A used Chevrolet Bolt EV is one of the cheapest ways into an electric car, and the battery recall is the reason the price is what it is. Whether a specific car is a good buy comes down to one question most listings do not answer: did this Bolt get new battery modules, or did it get monitoring software? The two outcomes carry different warranties, different charging behavior and different risk. This page explains how to tell them apart from the VIN, which other recalls to confirm, and what to inspect on the car itself. Everything here is drawn from GM’s recall documents filed with NHTSA and GM’s own owner guidance; the new 2027 Bolt is a different vehicle and is not covered.
Which Bolts the Recall Covers
GM and LG traced the fires to two manufacturing defects, a torn anode tab and a folded separator, occurring together in the same cell. The recall grew in three steps: an interim software charge cap in November 2020 (20V-701), module replacement for 2017–2019 cars in July 2021 (21V-560), and an expansion to every remaining first-generation Bolt in August 2021 (21V-650). GM halted Bolt production in August 2021 and restarted it in April 2022; 2022 cars built after the restart, and all 2023 cars, were never in the campaign.
| Model years | Recall | What the car should have received |
|---|---|---|
| 2017–2019 Bolt EV | 20V-701, then 21V-560 (GM N212343880) | New battery modules. No software-only option existed for these years |
| 2020–2022 Bolt EV, 2022 Bolt EUV (built before the pause) | 21V-650 (GM N212345940) | Either new modules or GM’s Advanced Diagnostic Software, depending on eligibility |
| 2022 built after April 2022, all 2023 EV and EUV | Not included | Original pack with post-fix cells; standard warranty only |
Until a car was remedied, GM told owners to cap charging at 90% using Hilltop Reserve (2017–2018) or Target Charge Level (2019–2022), avoid running below about 70 miles of range, and park outside after charging. If a seller still describes those habits, ask why.
Two Remedies, Not One
Module replacement. New LG modules, installed at a dealer over about two days. GM attached a separate Bolt EV Battery Limited Part Warranty to the new battery: 8 years or 100,000 miles from the installation date, tied to the VIN, so a 2018 Bolt fixed in 2023 carries battery coverage into 2031. Owners of 2017–2019 cars generally report more usable capacity afterward, because the replacement modules match the larger pack fitted to later cars.
Advanced Diagnostic Software. Introduced in late 2021 and, from 2023, accepted by GM as the recall closure for eligible 2020–2022 cars. The software caps charging at 80% while it monitors the pack; after about 6,200 miles with no anomaly it lifts the cap to 100% on its own and keeps monitoring. GM considers the recall resolved once it is installed. If it flags a module, the dealer replaces that module. There is no warranty extension with this path: coverage stays at the original 8 years or 100,000 miles from the first sale date. A class settlement paid software-remedy owners for the difference, but claims closed in 2025 and nothing from it transfers to a buyer.
The software path has needed cleanup. In June 2024 GM re-recalled 72 cars where it had been installed incorrectly (24V-481), and in October 2024 another 107 where installation had failed outright (24V-812). Both are tiny populations, but they are exactly the cars a careless seller would not know about.
How to Check a Specific VIN
- NHTSA recall lookup. Shows open campaigns only. A clean result means nothing is outstanding; it does not tell you which remedy was performed.
- GM Owner Center or the Chevrolet app, Warranty tab. This is the decisive check. A car with replaced modules shows a line reading Bolt EV Battery Limited Part Warranty with an expiry roughly eight years after the repair. A car on the diagnostic software shows only the original EV component warranty. The seller can pull this up on their phone in a minute; GM says the new warranty appears in its systems within 30 days of the replacement.
- Dealer service history by VIN. Any Chevrolet dealer can read the recall closure. Ask whether N212343880 or N212345940 closed with module replacement or with software, and whether 24V-481 or 24V-812 ever applied.
- Vehicle history report. Carfax entries for the recall period will say “software update” or describe a battery repair; the report is a cross-check, not proof.
- In the car. If Target Charge Level will not go above 80%, the software is still in its monitoring window; note the odometer against the install date. On a 2017–2019 car, a full-charge range estimate in the high 250s rather than the 230s is consistent with new modules.
Other Recalls on the Bolt
Thirteen NHTSA campaigns cover the 2017–2023 Bolt EV. Beyond the battery, two are worth confirming on any car, and the rest are small or year-specific.
| Model years | NHTSA number | Issue | Remedy |
|---|---|---|---|
| 2017–2023 | 22V-930, redone as 23V-845 | Seat belt pretensioner exhaust could ignite carpet after a crash | Metal foil at the carpet, pretensioner cover; some cars fixed under 22V-930 needed a second visit |
| 2022–2023 | 23V-567 | Instrument panel missing the airbag tear seam | Instrument panel replaced |
| 2022 EV and EUV | 21V-517 | Driver airbag fastener missing or loose | Inspect and tighten or replace |
| 2020 | 20V-808 | Front-left brake caliper casting could fracture | Inspect casting lot, replace |
| 2020 | 20V-811 | Wrong seat-belt anchor bolts | Bolts replaced |
| 2019–2020 | 20V-184 | Rear door-handle cable could let the door open from inside | Cables replaced |
| 2018–2019 | 18V-576 | Rear caliper piston coating, reduced braking | Brake system bled |
Beyond the Battery: What to Check
- The fast-charge port. DC fast charging was an option, RPO code CBT, on 2017–2021 cars; it became standard with the 2022 refresh. Open the charge door and look for the lower cover below the J1772 socket. Without it the car charges on Level 2 only, and a road trip becomes an overnight stop. Even equipped cars peak around 55 kW.
- Onboard charger. 7.2 kW through 2021, 11.5 kW from 2022. On a 48-amp home unit a 2022–2023 car charges noticeably faster; on a 32-amp unit there is no difference.
- Cabin heater. The electric PTC heater is the most reported non-battery failure, and it can throw a Service High Voltage Charging System message. Run the heat on full from cold during the test drive and make sure the air actually gets hot.
- Infotainment. Freezing, black screens and reboots are most common on 2017–2020 cars. Run navigation, phone projection and the camera for the whole drive.
- Charge-port latch. The motorized lock can stick either way, trapping the cable or refusing to hold it. Plug in and unplug twice.
- Reduced-power warnings. A Propulsion Power Is Reduced message or turtle icon on a remedied car points to a low-voltage cell and belongs at a dealer before money changes hands.
- Brakes and 12V. Regeneration leaves rear brakes idle; check for seized calipers and uneven pad wear. The 12V battery is a wear item here as on any EV.
- Charge cord. 2022 EUVs came with the dual-level cord that plugs into 120V or a 240V NEMA 14-50; on the 2022 EV it was optional. Missing cords cost real money to replace.

FAQ
Is a 2020–2022 Bolt with the software remedy safe to buy?
GM’s position is that the software closes the recall, and the two follow-up campaigns in 2024 covered installation errors, not new fires. The practical difference for a buyer is warranty: the original pack is covered to 8 years or 100,000 miles from first sale, so a 2020 car is inside the last two years of battery coverage. Price accordingly.
Can I still get the modules replaced for free?
Only if the diagnostic software flags a module, or if the car was never remedied and the VIN still shows an open campaign. A car that closed the recall with software is not entitled to new modules on request.
Does the replacement-battery warranty transfer to me?
Yes. GM assigned the Bolt EV Battery Limited Part Warranty to the VIN, not to the owner, and it runs 8 years or 100,000 miles from the installation date.
Was the 2023 Bolt part of the battery recall?
No. Production restarted in April 2022 with revised cells, and neither those late-build 2022 cars nor any 2023 EV or EUV was included. The 2023 is still covered by the pretensioner and instrument-panel recalls above.
Why is DC fast charging so slow on this car?
The first-generation Bolt was never fast: about 55 kW at best, tapering hard above half charge. Owners also report lower peaks, often 30–40 kW, after the recall software and in cold weather. If the seller says it fast-charges in 30 minutes, that means 100 miles added, not a full pack.
