Tesla’s standard extended warranty does not cover the high-voltage battery. The month-to-month Extended Service Agreement that most owners think of as “the extended warranty” specifically excludes the battery, drive unit, and 12V battery. To extend coverage on the battery itself, you need a separate product: Tesla’s Battery Extended Service Agreement (currently available only for Model 3 and Model Y) or a third-party service contract that covers EV batteries.
What the Factory Battery Warranty Already Covers
Every new Tesla comes with a Battery and Drive Unit Limited Warranty that runs eight years, with a mileage cap that varies by model:
- Model S and Model X: 8 years or 150,000 miles
- Model 3 and Model Y (Standard/RWD): 8 years or 100,000 miles
- Model 3 and Model Y (Long Range/Performance): 8 years or 120,000 miles
- Cybertruck: 8 years or 150,000 miles
All of these guarantee that the battery will retain at least 70% of its original capacity during the warranty period. If the pack falls below that threshold, Tesla replaces it at no cost.1FindMyElectric. The Ultimate Guide to Tesla Warranty Coverage Some pre-2020 Model S and Model X vehicles with 70 kWh or larger packs carry an even more generous term: 8 years with unlimited miles.2FindMyElectric. Tesla Battery Replacement Cost Explained
The warranty language excludes “gradual energy or power loss over time due to or resulting from Battery usage,” which reads like it could swallow the 70% guarantee. In practice, Tesla treats the 70% floor as a hard trigger. Degradation above that line is normal wear; a drop below it inside the warranty window qualifies for replacement. The documents do not spell out a more detailed formula.1FindMyElectric. The Ultimate Guide to Tesla Warranty Coverage
Both the factory battery warranty and any Battery ESA you purchase transfer with the vehicle once Tesla completes the ownership transfer.
Why the Standard ESA Subscription Does Not Help
Tesla’s month-to-month Extended Service Agreement covers repair or replacement of most mechanical and electrical parts that fail under normal use, with a $100 deductible per visit and coverage lasting up to four additional years or 100,000 miles.3Drive Tesla Canada. Tesla Launches Monthly Extended Warranty Program in the U.S. Monthly pricing runs roughly $50 for a Model 3, $60 for a Model Y, $125 for a Model S, and $150 for a Model X.4Jowua.

The plan explicitly excludes the high-voltage battery, drive unit, and 12V battery.3Drive Tesla Canada. Tesla Launches Monthly Extended Warranty Program in the U.S. Once the original Battery and Drive Unit Limited Warranty expires, this subscription will not help with a failed pack.
Tesla’s Battery ESA: The Real Extended Battery Coverage
For Tesla-backed protection past the factory battery warranty, Tesla sells a separate Battery Extended Service Agreement. As of 2026 it is available for Model 3 and Model Y vehicles only:
- Cost: approximately $2,000, paid upfront as a one-time purchase
- Term: adds 2 years or 30,000 miles to the existing Battery and Drive Unit warranty
- Deductible: $500 per visit
- Coverage: mechanical failure of the high-voltage battery and drive unit
- Exclusion: does not cover gradual range degradation
That last line matters. The Battery ESA protects against outright component failure, not the slow capacity loss most owners worry about.4Jowua. Is Tesla’s Extended Warranty Worth It – 2026 Edition That said, gradual degradation below 70% while your factory warranty is still active remains covered by that original warranty.
The Purchase Window
The Battery ESA has to be purchased before the original Battery and Drive Unit Limited Warranty expires. There is no grace period. If the warranty lapses by a single day or mile, the vehicle becomes ineligible.

If You Own a Model S or Model X
The Battery ESA in its current form does not cover Model S or Model X. Tesla has announced plans to introduce additional extended coverage for high-voltage batteries in 2026, possibly as a subscription costing between $100 and $200 per month depending on model and battery size, but full details have not been confirmed.6Drive Tesla Canada. Tesla to Launch Extended Warranty Battery Plans in 2026 Until that lands, Model S and Model X owners looking for extended battery protection have to go outside Tesla.
Third-Party Plans That Cover the Battery
Several service contracts now cover EV batteries, and they are useful if you own a Model S or X, bought your Tesla used from a third party, or let your factory warranty run out.
AmberCare
Amber offers service contracts exclusively for Tesla vehicles (Model S, 3, X, and Y) with fewer than 200,000 miles.7Forbes. Amber Scores Millions for Tesla Extended Warranties Three tiers are available: a Basics plan from around $65 per month that excludes the battery and drive unit, an Essentials plan from roughly $70 per month covering only the battery and drive unit, and a Premium plan from about $90 per month that covers both.8Amber. AmberCare Plans In California, Amber operates through a “Battery Club” membership rather than a traditional warranty, with terms lasting one year or 20,000 miles. One documented case on the Tesla Motors Club forum involved a 2016 Model S with 158,000 miles; the owner’s rear drive unit failed, Tesla quoted about $7,300, and Amber reimbursed all but $270 within three days.9Tesla Motors Club. A Review of Amber EV’s Battery Club Membership Warranty Like Tesla’s Battery ESA, Amber’s coverage focuses on component failure rather than gradual capacity loss.
XCare EV Protection
Xcelerate Auto offers two relevant plans. XCare EV Premium is broad coverage including the high-voltage battery for vehicles seven years old or younger with under 100,000 miles. XCare Battery and Drive Unit is a narrower, Tesla-only plan covering up to $25,000 in battery replacement costs. Both allow repairs at Tesla Service Centers or approved third-party shops, with deductibles of $0, $100, or $500.10Xcelerate Auto. XCare EV Protection Unlike Tesla’s ESA, these plans are available regardless of whether the factory warranty is still active, and used-vehicle buyers can purchase them.11Xcelerate Auto.

What Can Void Battery Coverage
Whichever route you take, several conditions can void battery coverage, and some catch owners off guard:
- Unauthorized service: opening or servicing the battery pack or drive unit through non-Tesla or non-certified personnel.12Tesla. Model 3 New Vehicle Limited Warranty
- External damage: physical impact to the underside of the vehicle, including scrapes or dents to the battery shield from road debris, rocks, or ice.13Torque News. Tesla Model Y Battery Warranty Denial – Analyzing the External Damage Clause
- Improper charging: letting the battery sit at 0% for extended periods, or using the vehicle as a stationary power source.1FindMyElectric. The Ultimate Guide to Tesla Warranty Coverage
- Modifications: physical alterations, programming changes, or unauthorized software and third-party applications.12Tesla. Model 3 New Vehicle Limited Warranty
- Salvage or flood damage: vehicles titled as salvage, flood-damaged, or total loss are generally excluded.
- Skipped software updates: failing to install updates after notification can void warranty rights.
The external damage clause has become a particular sore point. In one widely discussed case, a 2025 Model Y owner with fewer than 20,000 miles had a battery failure claim denied because Tesla’s service center identified underside damage, and the replacement quote came to $17,000. The stock underbody shield is primarily aerodynamic plastic and offers limited protection against road hazards.13Torque News. Tesla Model Y Battery Warranty Denial – Analyzing the External Damage Clause Photographing the underside during service visits helps document its condition, and some owners install aftermarket aluminum or steel skid plates for added protection.
What Replacement Costs Without Coverage
Through a Tesla service center, a full pack replacement runs roughly $13,000 to $20,000 depending on the model, with Model S and Cybertruck at the higher end.2FindMyElectric. Tesla Battery Replacement Cost Explained Tesla often uses remanufactured packs for service replacements, and customer-paid replacements (new or remanufactured) come with a 4-year, 50,000-mile limited warranty on the replacement part.14Tesla Motors Club. Firsthand Experience With Out-of-Warranty Battery Replacement Cost Tesla generally does not perform component-level repairs; the standard remedy is a full pack replacement.13Torque News. Tesla Model Y Battery Warranty Denial – Analyzing the External Damage Clause
Third-party specialists bring costs down. Aftermarket replacement packs range from roughly $6,500 for a Model 3 or Y to $11,500 for a Model S or X, savings of 30 to 50 percent compared with Tesla pricing.14Tesla Motors Club. Firsthand Experience With Out-of-Warranty Battery Replacement Cost Independent shops such as Gruber Motors and Electrified Garage can sometimes do module-level repairs rather than full pack swaps, cutting costs further. Most Tesla batteries retain 80 to 90 percent of capacity after eight to ten years of use, so total failure before the factory warranty expires remains uncommon.15Greentec Auto. Tesla Model S Battery Replacement – Cost, Specs, Warranty, Aftermarket Options Those numbers explain why the $2,000 Battery ESA appeals mainly to Model 3 and Y owners planning to keep the car well past year eight, and why third-party plans exist at all.
