EV Warranty Coverage by Model: Basic, Battery, Corrosion and Roadside Terms

Last verified October 25, 2026

Re-verification overdueThis guide remains available for context but is not presented as current until it is rechecked.

An EV's warranty is not one number. Basic vehicle coverage, high-voltage battery coverage, battery-capacity protection, electric-drive coverage, corrosion protection and roadside assistance can use different clocks and mileage limits — and exclusions can have very different consequences.123456789101112131415

This is a deliberately source-versioned U.S. starter matrix. It compares the warranty layers a current new-EV buyer is likely to care about without turning unlike programs into a subjective best warranty ranking. A blank or not established field means the checked first-party surface did not establish that field for the stated scope; it does not mean the vehicle has no coverage.

The exclusions section below uses the same rule. It distinguishes whole-warranty void language from the more common damage/issue caused by an excluded condition is not covered wording. It does not use void as a generic synonym for every exclusion.

For a used EV, the more important questions are often whether battery coverage transfers, when the original clock started and how degradation coverage works. Those are maintained separately in ATC's used-EV battery warranty transfer and degradation guide.

Current U.S. warranty matrix

EV / exact checked U.S. source scope Basic / new-vehicle coverage Battery / EV-system coverage Capacity / degradation state Corrosion / other useful layers Roadside state Scope and clock note
Tesla Model Y — current U.S. listed warranty terms 4 yr / 50,000 mi Basic Vehicle Limited Warranty.1 Current Model Y RWD/AWD: 8 yr / 100,000 mi Battery and Drive Unit; current listed Premium RWD/AWD/Performance and Model Y L Premium Launch Series: 8 yr / 120,000 mi.1 Minimum 70% battery-capacity retention during the applicable battery/drive-unit term.1 Supplemental Restraint System 5 yr / 60,000 mi; Body Rust 12 yr / unlimited mi. MY2027+ Model 3/Y may also have an 8 yr / 80,000 mi Emissions Performance Warranty on eligible components.1 Not established on the checked warranty page. Tesla says the warranty supplied with the individual vehicle is authoritative and earlier purchases may have different terms. Do not apply this live support table retroactively by model year.1
2026 Ford Mustang Mach-E — current U.S. product page 3 yr / 36,000 mi bumper-to-bumper.2 High-voltage battery: 8 yr / 100,000 mi.2 Battery coverage states minimum 70% of original capacity over the 8-year/100,000-mile period.2 Other EV-component, corrosion and restraint-system terms are not established on the exact checked 2026 product page; Ford directs readers to the BEV Warranty Guide for details.2 Not established on the checked 2026 product page. The current product page establishes the basic and battery layers for MY2026. The exact 2026 BEV Warranty Guide supplies the exclusions/limitations used below.29
2026 Hyundai IONIQ 5 — current U.S. product + 2026 warranty-handbook scope 5 yr / 60,000 mi New Vehicle Limited Warranty.3 10 yr / 100,000 mi Hybrid/Electric Battery Warranty; the product page also lists 10 yr / 100,000 mi Powertrain Limited Warranty.310 Hyundai's exact 2026 warranty handbook states that warranty-period battery-capacity degradation below 70% of original capacity is covered under its stated repair/replacement approach.10 Anti-perforation: 7 yr / unlimited mi.3 5 yr / unlimited mi 24/7 Roadside Assistance.3 Hyundai says the battery term runs from original retail delivery or first use under its stated conditions; the exact 2026 handbook supplies the stronger capacity and exclusion detail used on this page.310
2026 Toyota bZ Woodland — exact U.S. FAQ + launch + current Toyota BEV warranty page 3 yr / 36,000 mi basic new-vehicle warranty.14 Electric Vehicle Driving Components, including the traction battery: 8 yr / 100,000 mi, whichever comes first.1314 Toyota's current U.S. all-electric warranty page says BEV battery coverage protects against abnormal capacity loss and provides for a minimum 70% of original BEV battery capacity.15 Powertrain: 5 yr / 60,000 mi; corrosion: 5 yr / unlimited mi.14 3 yr / unlimited mi Roadside Assistance.1314 Toyota's exact Woodland sources establish the 8-year/100,000-mile EV-component term. Toyota's separate 10 yr / 150,000 mi battery term is labeled for hybrid batteries, not this BEV.1315 The exact Woodland FAQ does not itself restate the 70% capacity threshold; that field comes from Toyota's current U.S. BEV warranty page.15
2026 Nissan LEAF — S+ / SV+ / Platinum+, current U.S. Nissan product/EV benefits 3 yr / 36,000 mi basic.16 Powertrain and electrical/EV-system layers: 5 yr / 60,000 mi; lithium-ion traction battery: 8 yr / 100,000 mi.1617 Nissan separately lists lithium-ion battery-capacity coverage: 8 yr / 100,000 mi, but the redesigned MY2026 capacity-loss trigger and remedy are not established by these checked sources; do not import the previous LEAF's capacity-bar rule.1718 Corrosion/perforation: 5 yr / unlimited mi.1617 3 yr / 36,000 mi.16 Exact currently displayed U.S. S+/SV+/Platinum+ scope. Terms are summaries, not a VIN-specific entitlement; the controlling written warranty and applicable in-service date, exclusions and transfer terms matter.1617
2026 Kia EV9 — current U.S. EV9 inventory + Kia U.S. warranty program Exact 2026 EV9 inventory lists 5 yr / 60,000 mi Limited Basic Warranty.4 Exact 2026 EV9 inventory lists 10 yr / 100,000 mi Limited Battery Warranty and 10 yr / 100,000 mi Limited Powertrain Warranty.4 Not established on the checked current U.S. EV9 inventory/warranty pages. Kia's current U.S. warranty-program page lists 5 yr / 100,000 mi Limited Anti-Perforation Warranty for 2008+ Kia vehicles; the exact EV9 inventory page checked does not separately restate that layer.5 Exact 2026 EV9 inventory lists 5 yr / 60,000 mi Roadside Assistance; Kia's current U.S. program page also lists 5 yr / 60,000 mi.45 The exact EV9 inventory page establishes the basic, battery, powertrain and roadside layers. The checked public pages do not establish a battery-capacity threshold or a complete EV9-specific warranty-start rule for this matrix.45
2026 Polestar 4 — current U.S. product page 4 yr / 50,000 mi vehicle warranty after delivery.6 High-voltage battery: 8 yr / 100,000 mi.6 If battery State-of-Health falls below 70% of original capacity within the term, Polestar says the battery will be repaired or replaced at no cost.6 Corrosion: 12 yr after delivery for covered body perforation.6 4 yr complimentary roadside assistance.6 The current U.S. page's active Sept. 2026 offer identifies the advertised Polestar 4 as MY2026; warranty text is presented on that current product surface.6
2027 Volvo EX90 — current U.S. support/manual scope 4 yr / 50,000 mi New Vehicle Limited Warranty.7 High-voltage battery: 8 yr / 100,000 mi; 12V battery: 4 yr / 50,000 mi full coverage.7 A numeric high-voltage battery capacity-retention threshold is not established on the checked EX90 warranty page.7 Seatbelts/SRS: 5 yr / unlimited mi; corrosion protection: 12 yr / unlimited mi; adjustments: 1 yr / 12,000 mi.7 Volvo Assistance warranty coverage: 4 yr / unlimited mi. The page separately says out-of-warranty vehicles can receive complimentary towing to an authorized Volvo retailer within a stated radius.7 The checked page is explicitly scoped to EX90 2027 and tells owners to consult the service and warranty booklet for detailed terms.7
2027 Chevrolet Bolt — exact U.S. Chevrolet model FAQ and announcement; complete written MY2027 booklet not yet audited Chevrolet's exact 2027 Bolt FAQ lists 3 yr / 36,000 mi Bumper-to-Bumper New Vehicle Limited Warranty.19 Chevrolet lists 8 yr / 100,000 mi limited battery coverage; complete motor/EV-system scope is not established by these model summaries.2019 Not established; do not import older Bolt capacity-loss remedies. Not established in the checked exact-model summaries. Chevrolet's general U.S. EV page advertises 5 yr / 60,000 mi roadside and 8 yr / 100,000 mi towing for 2016+ Chevrolet EVs; the exact 2027 Bolt written terms have not been independently audited.21 Maker FAQ/benefits-page scope, not complete warranty certification. Vehicle-specific MY2027 written booklet, conditions and in-service clock control. Optional EV Protection remains a separate sample-dependent service contract.201921

Original auxiliary/12V battery versus replacement-part coverage

A low-voltage battery's warranty depends on how that particular battery entered the vehicle. The original factory-fitted battery, a separately paid service part, and a battery installed to resolve a previous warranty claim can follow different time and mileage limits. Those clocks should not be confused with high-voltage traction-battery protection. The table compares published written policy for exact U.S. document versions; it does not determine any individual warranty claim.17102223

Exact U.S. vehicle/manufacturer document scope Factory-installed auxiliary battery Separately purchased OEM replacement Battery replaced through a warranty claim / does the clock restart? What still controls a real claim
2026 Hyundai IONIQ 5 — Hyundai's 2026 U.S. Owner's Handbook & Warranty Information Hyundai's 2026 handbook separately specifies 3 yr / 36,000 mi for the original 12V battery, subject to the booklet's conditions; do not substitute the IONIQ 5's 10 yr / 100,000 mi high-voltage battery term.10 For eligible Hyundai Genuine parts purchased and installed by an authorized Hyundai dealer, this handbook specifies 12 months / 12,000 miles from installation, whichever comes first; qualifying dealer-installed parts and labor are covered. Parts bought over the counter but not dealer-installed instead have 12 months from purchase under the separately worded rule; that OTC clause does not state the same 12,000-mile cap, and installation labor is not covered.10 A component replaced under the New Vehicle Limited Warranty continues for the remaining period of that underlying warranty in the checked handbook. This does not prove that every auxiliary-battery repair, goodwill repair or service-part replacement restarts or follows the same clock.10 Confirm the VIN, in-service date, diagnosis, specific warranty program used on the repair order, genuine part, original invoice and dealer/owner service conditions. Lease reimbursement and an individual's entitlement are not established by this comparison.
Rivian R1T/R1S — U.S. warranty guide revised Dec. 31, 2024 This exact guide separately lists the 12V battery: 3 yr / 36,000 mi, subject to the stated exclusions. This is not automatically the warranty for a later R2 or for every 2026 vehicle.22 Rivian's separate genuine Service Parts Limited Warranty provides 24 months under its stated conditions. It distinguishes Rivian-performed service from over-the-counter purchases and excludes OTC installation labor.22 Under the cited guide, a part replaced under the new-vehicle warranty carries the remaining original vehicle-warranty period; a part replaced under the service-parts warranty carries the remaining original service-parts period rather than a brand-new 24 months.22 Check that the Dec. 31, 2024 guide applies to the vehicle, obtain the original repair/sale record, identify warranty versus paid-service installation and inspect Rivian's exclusions and version-specific terms.
Tesla — current U.S. warranty support and Dec. 1, 2025 Parts Limited Warranty Tesla lists a 4 yr / 50,000 mi Basic Vehicle Limited Warranty, but the checked summary does not independently specify the original low-voltage battery's part-specific factory coverage. That cell remains not established; the traction battery/drive-unit warranty cannot be substituted.1 Tesla's separately published Parts, Accessories and Body Repair Limited Warranty generally lists 12 mo / 12,500 mi for eligible purchased Tesla-branded parts; Tesla-installed versus third-party/owner-installed labor follows different terms. Applicability to a particular paid low-voltage battery requires the specific part/invoice and controlling edition.23 The cited Tesla policy distinguishes repairs made under another vehicle warranty or service plan (follow that underlying term) from replacements made under the purchased-parts warranty (its own remaining-period and written conditional minimum language). Do not treat the parts-warranty rule as a new factory-warranty clock.23 Obtain the vehicle's supplied warranty, actual auxiliary-battery type, Tesla service order, purchased-part date/mileage and whether the prior repair was factory-warranty, parts-warranty, or paid service.
2027 Volvo EX90 — exact U.S. Volvo manufacturer support scope Volvo's EX90-specific U.S. warranty page separately lists the 12V battery: 4 yr / 50,000 mi, distinct from the 8 yr / 100,000 mi high-voltage battery term.7 Not established by the checked exact-EX90 warranty summary: no controlling purchased Volvo service-battery parts term was verified here. Not established by that summary: whether a warranty-installed 12V battery inherits remaining factory coverage or receives another conditional term is not specified there. The delivered vehicle's detailed service and warranty booklet, repair order, purchased-parts policy, in-service date and exclusions; no automatic lease or used-owner result inferred.

Before agreeing to pay or assuming a free replacement, ask the service provider to identify the claim type in writing. Useful documentation is the original in-service date and odometer, battery part number, diagnostic finding, previous repair order and mileage, whether the component was purchased or installed under a warranty, and the precise written policy revision. A prior warranty replacement does not automatically reset a full factory warranty; the exact governing policy decides.102223

The separate low-voltage dead-vehicle access and recovery guide covers physical access, jump-support and service constraints, not financial coverage. For a used EV's traction-battery transfer or degradation provisions, see the used battery-warranty guide. Owner anecdotes do not establish a defect rate, OEM claim denial, or what a warranty must pay.

Source-edition boundary (October 27, 2026): The four manufacturers' low-voltage terms in this section were checked against the cited source editions. That targeted verification does not refresh every older whole-vehicle warranty entry elsewhere on this page or establish any specific signed 2027 Bolt protection contract. The dated policy and actual repair order remain decisive for a particular owner.

2027 Chevrolet Bolt: factory warranty versus optional EV Protection Plan

Separate the manufacturer's original warranty from a dealer's optional service contract. This section is a document-and-questions checklist, not confirmation that a particular 2027 Bolt qualifies for any optional plan, or a recommendation to purchase it. Chevrolet's 2027 Bolt U.S. model FAQ specifies 3 years/36,000 miles of basic bumper-to-bumper coverage and 8 years/100,000 miles of limited battery coverage, consistent with the original launch announcement.1920 Chevrolet's separate general EV owner-benefits page advertises roadside and towing durations for 2016+ Chevrolet EVs, not a directly inspected, controlling MY2027 Bolt warranty booklet.21 Exact 2027 component, degradation, corrosion, eligibility, exclusions and clock wording remain not independently established here. A not established matrix field does not mean no such benefit exists.

Chevrolet currently markets a separate EV Protection Plan, including Platinum for up to 96 months/100,000 miles and deductible selections of $0, $100, $100 disappearing or $250. An advertised maximum does not prove a particular 2027 Bolt is eligible, does not quote its actual price, and does not establish an extra eight years of high-voltage battery coverage.24

The buyer's decision What the original Chevrolet sources establish What the buyer still needs to verify
Already included versus paid option Original Bolt limited-battery coverage is manufacturer-advertised; EV Protection is a separate optional purchase. Chevrolet's sample contract says it is not a vehicle-sale, lease or financing condition.202425 Exact vehicle's 2027 written warranty and the optional offer's eligibility, signed contract form and price.
Do the advertised plan years start after factory coverage? Chevrolet's FAQ says factory and optional-plan time runs concurrently. Its maker-hosted sample says manufacturer-covered parts are not paid under the service agreement until the manufacturer/supplier warranty ends, while the service-agreement clock already runs.2625 Compare actual years of incremental eligible repair coverage, not simply sum the advertised numbers.
Clock, mileage and Wrap selection The CHEVSC 10/23 sample starts non-Wrap terms from contract purchase date/odometer and measures selected Wrap expiry from manufacturer's original in-service date/odometer; the signed registration controls selected term.25 In-service date, agreement-purchase date, selected plan term, Wrap option, final expiry date/miles and applicable state rider.
Is a traction battery or charger covered by the optional plan? The maker-hosted sample, in its exclusions, explicitly lists BATTERIES and certain mobile/wall connectors, adapters and hardwired charging equipment. This describes that sample form, not all signed 2027 Bolt contracts or factory-warranty coverage.25 The exact plan's covered and excluded parts, HV pack/drive-unit clauses and state amendments. Do not infer high-voltage-battery replacement from the plan's EV branding.
Buy later, waiting and transferable benefits Chevy's public FAQ describes qualified purchases after delivery while the original limited warranty has at least 1,000 miles or 30 days remaining before expiry. Its sample includes conditional waiting rules for later purchase, and the published EV Plan describes transfer/cancellation options.262425 Dealer/VIN eligibility, agreement effective date, waiting-period trigger, claim authorization, transfer and refund terms in writing. No universal waiting period or later eligibility is established.
Is a quoted plan actually worth the price? Chevrolet's marketing and sample identify potential benefits, deductible and contract-price fields but no exact 2027 Bolt quote or prospective failure rates.2425 The actual total price, deductible, incremental covered components/years, exclusions and personally relevant risks. There is no evidence here to estimate savings or claim all buyers should purchase/decline.

Document scope (October 26, 2026): The Chevrolet-hosted 16-page CHEVSC 10/23 PDF is a sample, with state variations, not a completed 2027 Bolt agreement. It was read and its sample agreement/overlap and exclusions were checked in the rendered pages.25 Chevrolet's original 2027 electric-vehicle warranty PDF has a specifically indexed manufacturer URL, but its approximately 14.9 MB response exceeded this review's document-retrieval limit on October 28, 2026. Its pages were not fully inspected, so this table does not rely on that PDF for unstated 2027 Bolt provisions. An earlier link missing the /2027/chevrolet/ directory returned 404; that is not proof the actual 2027 document does not exist. Chevrolet's directly inspected 2027 Bolt warranty FAQ explicitly directs buyers to the warranty materials provided with the vehicle for complete terms.19 Obtain those exact factory materials and the actual signed EV Protection agreement, including applicable state provisions and price, before relying on a coverage or cost comparison. Other manufacturers' rows retain their separate historical verification dates.

Toyota bZ Woodland: the hybrid and BEV battery terms are not interchangeable

Toyota currently publishes two conspicuous battery-warranty numbers on the same U.S. electrified-vehicle warranty surface: 10 years/150,000 miles for a Toyota hybrid battery and 8 years/100,000 miles for EV Drive Components.15 For the 2026 bZ Woodland, the exact model FAQ independently says its EV Component Warranty is 8 years/100,000 miles and includes the traction battery.13

That is why the Woodland row above does not import Toyota's longer hybrid-battery term merely because both vehicles are electrified. The capacity field is also kept separate: Toyota's current U.S. BEV warranty page states a minimum 70% of original BEV battery capacity protection, while the exact Woodland FAQ itself does not restate that percentage.1315

The complete exact-model Warranty & Maintenance Guide should still control details such as exclusions, remedies, state-specific layers and VIN-specific application. This update does not infer those details from the shorter FAQ or launch summary.

Nissan LEAF (2026): capacity-coverage duration is not a proven degradation threshold

Nissan's current U.S. 2026 LEAF Specs & Trims page lists the S+, SV+, and Platinum+ grades with 36 months/36,000 miles basic and roadside coverage, 60 months/60,000 miles powertrain and EV electrical coverage, 96 months/100,000 miles high-voltage battery coverage, and 60 months/unlimited miles corrosion coverage.16 Nissan's current EV Benefits page separately identifies 96 months/100,000 miles of lithium-ion battery-capacity limited warranty protection.17

The term is established, but the exact redesigned 2026 LEAF's degradation test, threshold, remedy, and exclusions are not established by those checked summary pages. In particular, a previous LEAF generation's nine-of-twelve battery-capacity-segment remedy18 must not be copied into a MY2026 row without an exact current, controlling 2026 LEAF warranty statement. Likewise, a published 8-year/100,000-mile term does not imply a universal 70% threshold or a guaranteed replacement remedy. Owners should check the warranty booklet issued for the actual VIN and model year for eligibility, limitations, transfer and start-clock details.

What can actually exclude EV battery or EV-system warranty coverage?

The useful question is not simply what voids the warranty? The checked current sources use several different consequences. A claim-level exclusion is not automatically the same thing as the entire new-vehicle warranty disappearing.

OEM / exact checked source scope Charging / battery-use conditions Third-party parts, service or HV work Warnings / software / maintenance Collision, fire, flood and title state Exact consequence boundary from the checked source
Tesla — Model S/3/X/Y New Vehicle Limited Warranty effective Sept. 1, 2026 + current U.S. support Tesla's support page says damage caused by third-party vehicle adapters or chargers is not covered. The warranty says resulting battery issues are not covered when recommended battery maintenance/charging procedures are not followed.18 Tesla says consumers may use non-Tesla providers or non-Tesla parts for non-warranty service and the New Vehicle Limited Warranty will remain in effect, but Tesla may exclude an issue arising from that service/repair/part. Battery/Drive Unit damage from service or opening by non-Tesla/non-certified personnel is excluded.8 Battery damage from intentionally ignoring active vehicle warnings/service notifications is excluded. The warranty also lists failure to install software updates and comply with recalls/repair instructions in its general exclusions/obligations.8 Collision/accident and battery flooding damage are excluded. Separately, Tesla's Voided Warranty section says it may void the whole NVLW in limited VIN/odometer, specified non-clean/branded-title or insurance-total-loss circumstances.8 Both categories exist: caused/issue-specific exclusions and a separate limited whole-warranty-void section. Do not collapse one into the other.8
Ford — 2026 Model Year BEV Warranty Guide / Mustang Mach-E Ford lists damage from incompatible charging devices or methods, extended near-zero state of charge over 14 days and improper storage among exclusions.9 Ford excludes damage caused by HV-battery/system/wiring modifications and repairs by unauthorized facilities/personnel. Aftermarket parts themselves may not be covered; damage they cause to Ford components is also excluded.9 Ford lists failure to resolve battery warnings and failure to complete Ford Power-Up updates, typically within 30 days, among battery-related exclusions.9 Accident/collision, fire and HV-battery immersion/flooding damage are excluded. Separately, specified dismantled/fire/flood/junk/rebuilt/reconstructed/salvage title branding and an insurer's total-loss determination will void the NVLW.9 Both categories exist: caused-damage/repair exclusions plus explicit whole-warranty-void title/total-loss states.9
Hyundai — 2026 Owner's Handbook & Warranty Information, USAHYUNDAI-250905 An exact blanket third-party-charger or DC-fast-charging warranty rule is not established in the checked handbook sections. Do not infer one from silence.10 Hyundai excludes damage/failure resulting directly or indirectly from non-equivalent parts, devices/accessories not supplied by Hyundai, modification/tampering and improper repair. Battery damage from service/opening by non-authorized personnel is separately excluded.10 Hyundai says failure to perform required maintenance invalidates warranty coverage on parts affected by the lack of maintenance. Battery damage from intentionally ignoring active warnings is excluded.10 Damage/failure resulting from accident, water/flood or fire is excluded; the handbook also lists vehicles ever declared total loss, scrapped or salvage/similar as not covered.10 The checked provisions use affected-part and resulting-damage/failure language. Do not rewrite them as a universal aftermarket part voids the whole warranty rule.10
Nissan — 2026 U.S. Warranty Information Booklet + current EV/2026 LEAF scope A current LEAF-specific third-party-charger exclusion table is not established in the checked 2026 general warranty booklet.1127 Nissan excludes damage/failures resulting from repairs by anyone other than an authorized Nissan dealer, alteration/tampering/improper repair, non-Nissan-approved accessories/components, improper installation of approved aftermarket accessories and non-equivalent parts.11 Nissan excludes damage/failures resulting from lack of or improper maintenance and failure to operate the vehicle according to the owner's manual.11 Accident/collision, fire and flooding are among the listed caused-damage exclusions. Separately, Nissan says specified salvage/similar branded-title states or an insurer's total-loss determination render the NVLW VOID.11 Both categories exist: resulting-damage exclusions and a separate explicit whole-warranty-void salvage/total-loss section.11

Aftermarket parts do not automatically mean the whole warranty is void

FTC's current automobile-warranty consumer guidance says using aftermarket or recycled parts does not by itself cancel the warranty. FTC also says that if a defective aftermarket/recycled part — or its improper installation — damages a covered part, the manufacturer or dealer can deny coverage for the damaged part, and FTC says the manufacturer/dealer must establish the causation before denying coverage on that basis.12

That federal consumer guidance is a useful boundary, not a VIN-specific legal determination. The actual written warranty, the facts of the repair/damage and applicable law still control an individual claim.

Why not established matters

If the checked warranty is silent about a specific activity — for example a particular charging network, fast-charging frequency or third-party charger — this page does not turn silence into safe, covered or void. A future exact source can change that row.

The exclusions matrix is currently representative rather than all-OEM. Toyota, Kia, Polestar and Volvo remain in the coverage-term matrix above, but this update does not manufacture detailed exclusion rows without current written-warranty depth comparable to the Tesla/Ford/Hyundai/Nissan source set.

Why a single 8 years / 100,000 miles column is not enough

Battery coverage is often the most visible EV warranty number, but the starter matrix shows several ways that a one-number comparison can mislead:

  • The basic-vehicle term can be much shorter than the battery term. The checked 2026 Mustang Mach-E page lists 3 years/36,000 miles basic versus 8 years/100,000 miles for the battery; the 2026 IONIQ 5 lists 5 years/60,000 miles new-vehicle coverage versus 10 years/100,000 miles for its electric battery.23
  • Capacity retention is a separate field from defect/EV-component coverage. Tesla, Ford, Hyundai, Polestar and Toyota's current U.S. BEV warranty page publish 70% capacity language, while the checked current 2026 EV9 and 2027 EX90 pages used here do not establish a numeric capacity trigger for those rows.12671015
  • The same automaker can publish different battery terms for different propulsion categories. Toyota's current U.S. page labels hybrid batteries at 10 years/150,000 miles and EV Drive Components at 8 years/100,000 miles; the exact 2026 bZ Woodland FAQ aligns with the EV term, not the hybrid term.1315
  • Corrosion and roadside terms vary independently. The checked sources range from Tesla's 12-year/unlimited-mile body-rust term to Hyundai's 7-year/unlimited-mile anti-perforation term and Kia's current U.S. 5-year/100,000-mile anti-perforation program.135
  • A live support page may not be the controlling document for an older vehicle. Tesla explicitly says the warranty supplied with the individual vehicle is authoritative, while Volvo directs EX90 owners to the service and warranty booklet for detailed terms.17

Use the exact vehicle and warranty revision

Before comparing warranties or exclusions, pin down:

  1. model year and configuration;
  2. the controlling U.S. warranty booklet or source revision;
  3. which layer is being compared — basic vehicle, battery, drive/electric components, capacity retention, corrosion, restraint system or roadside assistance;
  4. what consequence the source actually states — whole warranty void, caused-damage exclusion, affected-component loss, or something narrower;
  5. when the clock begins where the OEM directly states it; and
  6. whether the question is about a new buyer or a used buyer.

This page owns the current/new-buyer whole-vehicle comparison and source-versioned exclusion boundary. Transfer, original-in-service clocks for used buyers, CPO interaction and used-battery degradation eligibility remain in the used-EV battery warranty guide instead of being duplicated here.

For maintenance schedules that can affect warranty disputes or required service, use ATC's EV maintenance schedule matrix.

What is not established yet

This version does not fill unsupported rows from secondary warranty comparison sites.

  • Toyota bZ Woodland detailed exclusions/state-specific layers: exact current model sources establish the core coverage terms and Toyota's current U.S. BEV page establishes its capacity language, but this pass did not reproduce the exact 2026 Woodland Warranty & Maintenance Guide. Detailed exclusions, remedies, transfer rules and state-specific coverage therefore remain outside the row pending an exact controlling booklet.
  • 2026 Nissan LEAF exact battery-capacity remedy: 8-year/100,000-mile capacity coverage is separately published, but the checked summaries do not establish the redesigned vehicle's capacity-loss threshold, test, remedy or transfer exceptions; consult the exact MY2026 written warranty before making entitlement claims.1617
  • GM/Chevrolet/Cadillac beyond the scoped 2027 Bolt summary: the 2027 Bolt row above exists, but covers only Chevrolet's exact-model published basic/battery warranty summary and separately qualified general EV assistance terms. The full MY2027 Bolt booklet is not audited; no other GM-brand/model-year row or battery-capacity/drive-unit/exclusion/optional-plan entitlement is inferred from brand-level support pages.201921
  • Rivian: ATC has source-versioned battery-warranty material for MY2022-2025 in the used-buyer guide, but this page does not carry that older scope forward as a current model-year whole-vehicle row without a current exact warranty source.
  • Lucid: a current warranty page exists, but this pass did not promote it into the starter matrix while its surfaced model-year wording is internally awkward enough to merit a cleaner exact-scope recheck before publication.
  • Detailed exclusion rows for Toyota, Kia, Polestar and Volvo: not added in this update without current warranty-booklet depth comparable to the Tesla/Ford/Hyundai/Nissan source set.
  • Missing fields: not established is deliberate. Silence on the checked page is not proof that a coverage layer or exclusion does not exist.

Update policy

This is a frequently rechecked living reference. Reverify a row on a new model-year warranty booklet, a material OEM warranty/support-page revision, a battery-capacity/remedy change, a charging-adapter or charging-method warranty wording change, a software/update obligation change, a roadside/CPO program change, an FTC consumer-guidance change or an exact model/configuration change that alters a listed term.

The scheduled next review is October 31, 2026, with earlier verification on a controlling-source change. The 2026 LEAF capacity trigger/remedy remains a priority source gap; this is a recheck of the Nissan terms, not a claim that every older comparison row was independently reverified on October 24.

This guide summarizes published manufacturer warranty information and FTC consumer guidance. It is not legal advice or a VIN-specific coverage determination. The warranty supplied with an individual vehicle, applicable exclusions, vehicle use, mileage, in-service date, ownership state, facts of the damage/repair and jurisdiction-specific rights can control the actual outcome.
