Which electric models have been on the road long enough to show battery wear?
Of the 299,705 electric and plug-in hybrid vehicles in Washington's registry, NISSAN LEAF (BEV) has been on the road since model year 2011 and 13,453 are still registered, so batteries from the first generation of popular models are now eight or more years old.
What it shows: TESLA MODEL 3 (BEV) is the largest at 39,391, followed by NISSAN LEAF (BEV) at 13,453; the smallest shown is TOYOTA PRIUS PRIME (PHEV) at 4,334.
Has the maker published a fix?
A bulletin is a repair procedure a maker sends its dealers, not a safety defect: if your maker is listed, ask the dealer whether one covers your car and quote its number.
| Maker | Vehicles | Bulletin number | Date | What it says |
|---|---|---|---|---|
| Chevrolet | Bolt EV 2017–2020 | 19NA210 | Oct 13, 2019 | This bulletin provides information on conditions that may cause EV Range Loss and for dealers/technicians to determine/differentiate items which require battery repair versus which items are normal for the vehicle. |
Check your car
A full battery pack for a mid-range EV like a Tesla Model 3 or Model Y runs $8,800–$19,800. The biggest factor is how much of the pack gets replaced: a module swap costs $3,080–$6,930 and cell reconditioning costs $1,320–$2,970.
The median car in these complaints was only 3 years old (median age at failure, 43 complaints), so check your battery warranty before you pay. Also test the 12-volt battery, because the car battery is named in 84% of these complaints (36), far more often than in complaints overall.
Nissan Leaf leads EV battery degradation complaints, with peaks on 2015, 2016 and 2022 models
The Nissan Leaf has more battery degradation or range-loss complaints than any other model (7). They cluster on 2015, 2016 and 2022 models, so this is not only an older-car problem. The Leaf is in the calculator's small-EV class.
The Tesla Model S comes next with 5 complaints, on 2015 through 2017 models.
2023 and 2024 model-year EVs have the most EV battery degradation complaints
Owners of 2023 and 2024 models filed 8 complaints each, the most of any model year. The 2016 model year is next with 5. The median complaint came at 28,000 miles, so most owners reporting range loss were early in the car's life. A range-loss quote that low on the odometer is more likely a warranty question than a bill you have to pay yourself.
One in five EV battery range-loss complaints describes stalling or lost power
Owners described the car stalling or losing power in 21% of these complaints, and 12% mention a warning light. Loss of power is the most common outcome owners reported, at 14%. Owners reported 2 crashes and no fires or injuries, and just 2% needed a tow. In 23% of complaints the dealer could not fix the problem or had to repeat the repair. If your car has had a battery repair that did not hold, keep that paperwork before paying again.
Before you accept a range-loss diagnosis, note that the car battery is named in 84% (36) of the 43 EV battery complaints, so price a 12-volt battery replacement first.
EV battery module swap vs cell reconditioning on a Model 3/Y-size pack
If the diagnosis only names specific weak modules, a full-pack quote is paying for cells that still work.

What is our own estimate
The price range comes from our calculator's formula. Its parts prices, labor hours per job and shop-rate tiers are CalcScrape estimates, not a published price dataset. Not independently checked: no established price guide publishes a general range for this exact job (looked 2026-10-06), so the default has no outside comparison. Methodology
