Three NHTSA battery fire campaigns, propulsion warnings, charging limits. California Bolt EUV owners may qualify for a full GM buyback. Free review.
The Chevrolet Bolt EUV arrived for 2022 as GM's most affordable electric SUV — a practical everyday EV priced under $35,000, with the optional Super Cruise hands-free driving system as a differentiating premium feature. For many buyers, it delivered on that promise. For others, it became the center of one of the most prolonged safety-recall sagas in EV history. The core problem was present from day one: LG Energy Solution battery modules manufactured with two simultaneous defects — a torn anode tab and a folded separator — created a latent internal short-circuit risk. When the battery was charged to full or near-full capacity, thermal runaway and fire were possible. NHTSA recall 21V650 (August 2021) covered 7,366 Bolt EUV units alongside over 44,000 Bolt EVs. GM's interim fix told owners to limit charging to 90% and park outdoors after charging. The permanent fix — battery module replacement — took many months to execute across the fleet. Then the remedy itself started failing. In June 2024, recall 24V481 re-called 72 vehicles (Bolt EV and EUV combined) after GM discovered the advanced diagnostic software installed as the primary fix had been incorrectly deployed at some dealerships, leaving those vehicles without the monitoring layer designed to detect a defective cell. In October 2024, recall 24V812 re-called another 107 units for the same installation-failure issue — meaning some Bolt EUV owners went through three separate recall campaigns on the same underlying fire defect. Separately, 2022 and 2023 Bolt EUV owners who took delivery with the Webasto portable Level 1 charging cord faced a second recall (23E065) for an electric shock hazard when the cord's ground connection was lost. And Premier-trim owners with Super Cruise found the system frequently unavailable due to two separate software defects in the digital map module — a feature they paid extra for that repeatedly failed to operate. California owners who made multiple dealership visits for battery software re-installation, who lived under charging restrictions for months, or who experienced recurring propulsion warnings may have strong grounds for a lemon law evaluation.
The issues owners report most, ranked by severity — each one verified against a cited NHTSA source.
Vehicle fire or smoke emanating from battery area, especially after charging to full or near-full; warning lights; battery temperature alerts. Fire can occur while parked.
Charging remains limited to 80-90% state of charge beyond the expected 6,200-mile evaluation period; propulsion power reduced warnings; battery will not charge above 30% SOC; false DTC U3636 triggers MIL with 'Reduced Propulsion' and charging limit.
Charger fails to stop charging if ground connection is lost; potential brief electric shock when handling cord during or after a charging session.
Super Cruise refuses to activate on mapped highways; 'Super Cruise Unavailable' displayed on instrument cluster; 'Service Driver Assist' warning message; system drops out unexpectedly during use. DTC B126B may be set in the Digital Map Control Module.
Malfunction Indicator Lamp illuminated; Driver Information Center displays 'Propulsion Power is Reduced'; battery will not charge above 30% State of Charge; vehicle may operate normally after restart. History codes P0A3F and P1B03 may also set.
No driver-visible symptom before a crash; airbag may fail to deploy or may deploy improperly in a collision.

Open any defect for the symptoms and why it matters for a California lemon-law claim. Each is tied to a cited NHTSA source.
Vehicle fire or smoke emanating from battery area, especially after charging to full or near-full; warning lights; battery temperature alerts. Fire can occur while parked.
Catastrophic safety defect subject to three consecutive recalls (21V650, 24V481, 24V812) spanning 2021-2024. Owners whose vehicles required multiple repair visits for battery software/module remedy, or who experienced reduced charging capacity under interim restrictions, have strong lemon-law standing. 7,366 EUV units originally recalled; further sub-populations re-recalled twice for failed remedy installation.
Defective battery module replacement (or full pack replacement if needed); advanced diagnostic software (ADS) deployment via HPCM2 reprogramming to monitor cells and detect anomalies. Interim: charge limited to 90%, park outdoors after charging.
Charging remains limited to 80-90% state of charge beyond the expected 6,200-mile evaluation period; propulsion power reduced warnings; battery will not charge above 30% SOC; false DTC U3636 triggers MIL with 'Reduced Propulsion' and charging limit.
Owners who returned to the dealer multiple times for ADS software re-installation after 21V650 remedy failures accumulate repair visits on a single safety-critical defect. Charging restrictions (80-90% cap) constitute substantial impairment of vehicle use.
Reinstallation of correct advanced diagnostic software via HPCM2 reprogramming (SPS). Requires GM EV-certified dealer. No hardware parts required.
Charger fails to stop charging if ground connection is lost; potential brief electric shock when handling cord during or after a charging session.
Safety defect affecting the included charging equipment. GM characterized the shock as 'very brief' (1/40th of a second), but a shock hazard from a primary charging accessory is a safety-relevant defect. Applicable to 2022-2023 EUV owners with the specific Webasto cord.
Dealer inspection of charging cord; replacement if defective. Performed free of charge.
Super Cruise refuses to activate on mapped highways; 'Super Cruise Unavailable' displayed on instrument cluster; 'Service Driver Assist' warning message; system drops out unexpectedly during use. DTC B126B may be set in the Digital Map Control Module.
Super Cruise is a premium advertised feature on Premier trim (adds significant cost). Persistent unavailability after multiple dealer visits constitutes substantial impairment of a specific promised feature. Lane-keep assist ping-ponging and collision avoidance inconsistency add to ADAS complaint pattern.
TSB 1: Dealer updates map module data via USB. TSB 2: Toggle Wi-Fi Hotspot Share Hotspot to 'on' and reprogram HPCM2 / map module as directed.
Malfunction Indicator Lamp illuminated; Driver Information Center displays 'Propulsion Power is Reduced'; battery will not charge above 30% State of Charge; vehicle may operate normally after restart. History codes P0A3F and P1B03 may also set.
Repeated 'Propulsion Power Reduced' warnings with charge cap at 30% SOC effectively render the vehicle undrivable for its intended daily-use range. Multiple dealer visits for software reprogram without resolution of recurring propulsion warnings support a lemon-law claim pattern.
Dealer scan for DTC P0BBD; follow GM diagnostic procedure per TSB 22-NA-151. For false DTC U3636, ADS software update via HPCM2 reprogram (Service Update N222369401).
No driver-visible symptom before a crash; airbag may fail to deploy or may deploy improperly in a collision.
Very small affected population (8 EUV units). Relevant only if VIN confirmed in recall. Latent safety defect with no owner-observable symptom until crash event.
Dealer inspects and replaces as necessary the driver-side air bag fasteners. If fasteners cannot be tightened, the air bag assembly is replaced. Free of charge.

Every item below comes from this vehicle's documented defects. The more you recognize, the more a free case review is worth your time.
California's Song-Beverly Consumer Warranty Act applies to new vehicles purchased or leased in California. The law creates a presumption that a substantial defect exists when a manufacturer has made two or more unsuccessful repair attempts for a safety-related defect, or four or more attempts for any other substantial defect, or when the vehicle has been out of service for 30 or more cumulative days during the warranty period. If your Bolt EUV qualifies, you may be entitled to a full repurchase at the original purchase price (less a reasonable mileage offset), a comparable replacement vehicle, or a negotiated cash settlement. General Motors is required to pay your attorney's fees if you prevail, which means most California lemon law cases cost the owner nothing out of pocket. The Bolt EUV's battery fire recall chain — three consecutive NHTSA campaigns (21V650, 24V481, 24V812) over three years for the same fundamental defect, with some owners making multiple dealership visits for software reinstallation — represents the type of recurring safety issue California lemon law was designed to address. If your vehicle was also subject to charging restrictions for an extended period, that restriction on the vehicle's core function may constitute substantial impairment of use. The above is general information only and is not legal advice; results depend on the specific facts of your situation.
“Could not duplicate” doesn't mean the defect isn't real. Here's exactly what to do to protect a potential California lemon-law claim.
Document the moment it happens. Photos, video, and screenshots of any warning lights — with the date and the mileage.
Get a repair order every visit — even “found nothing.” That paperwork is the foundation of a claim.
Check your VIN at nhtsa.gov/recalls. Note any recall that has no available remedy yet.
Track your out-of-service days. California law counts the cumulative days your vehicle spends in the shop.
Keep loaner & rental records. Alternate-transport paperwork during long repairs matters.
Save everything in one place. Symptoms, dates, repair orders, and every repeat visit — the intermittent ones especially.
A 'could not duplicate' (CND) or 'no trouble found' (NTF) notation on your repair order does not end your lemon law rights — it still counts as a visit. Here is how to protect yourself when the dealer cannot reproduce the problem: 1. Document every occurrence before the visit: exact warning message wording, date, time, odometer reading, recent charging conditions, ambient temperature, and any warning lights. Take a photo of the instrument cluster if it is safe to do so. 2. Ask the service advisor to pull all stored and historical Diagnostic Trouble Codes — not just currently active ones. DTCs P0BBD, U3636, B126B, P0A3F, and P1B03 frequently appear in history even after a warning light has cleared. Ask for a printed copy of the full DTC history attached to your repair order. 3. Specifically ask whether TSB 22-NA-151 (P0BBD propulsion reduction), GM Service Update N222369401 (ADS software improvements), and TSBs N222-MAP-UKL-01 and N232-MAP-B126B-01 (Super Cruise map module) have been checked against your symptoms. Reference them by number if needed. 4. For battery recall work, confirm with the service advisor that the Advanced Diagnostic Software was installed correctly and ask them to note the ADS software version and HPCM2 calibration number on the repair order. This is how the re-recall failures were identified. 5. Keep every repair order including CND visits, software-only visits, and any notation of parts being on backorder. Days when the vehicle is at the dealer for a covered defect count toward California's 30-day lemon law presumption, even if the repair was not completed.
The Bolt EUV is fundamentally a capable, affordable electric SUV — and for most owners the battery fire recall was resolved without incident. But the owners who fell into the re-recall population, who made two or three dealer trips for the same ADS software fix, who lived under a 90% charging cap for months, or who experienced 'Propulsion Power is Reduced' warnings that kept returning after service visits, faced a very different ownership experience. Three NHTSA campaigns over three years for the same underlying battery defect is an unusual record for any vehicle. If your Bolt EUV has had repeated visits for battery-related warnings, software re-installations, or charging limitations, a free lemon law evaluation costs you nothing and may result in a full repurchase from GM.

If you own a 2022 Bolt EUV, your vehicle was covered by NHTSA recall 21V650 (issued August 2021). The defect: LG-manufactured battery modules containing two simultaneous manufacturing defects — a torn anode tab and a folded separator — that create a risk of internal short circuit and thermal runaway when the battery is charged to full or near-full capacity. 7,366 Bolt EUV units were included in the recall. The remedy involved replacing defective battery modules and installing Advanced Diagnostic Software via HPCM2 reprogramming. However, two follow-on recalls — 24V481 (June 2024, 72 total units) and 24V812 (October 2024, 107 total units) — were issued when GM discovered the software had been incorrectly installed at some dealerships, leaving those vehicles without proper battery monitoring. To confirm your specific VIN's recall status and whether any open campaigns remain, check nhtsa.gov with your 17-digit VIN.
Two separate documented causes can produce this symptom. The first is DTC P0BBD, a code indicating a battery cell chemistry anomaly. GM Service Bulletin 22-NA-151 (December 2022) provides a specific diagnostic procedure for this code, which may require a battery module evaluation or replacement. The second cause is a false DTC U3636 triggered by the Advanced Diagnostic Software under certain low-speed driving conditions — specifically simultaneous brake and accelerator application. The false code caused the system to unnecessarily cap charging at 30% state of charge. GM issued Service Update N222369401 (August 2022) to reprogram the HPCM2 with improved ADS software that reduces these false activations. If your 'Propulsion Power is Reduced' warning has returned after a dealer software update, or if the dealer noted 'no fault found,' ask specifically for the DTC history and request that both TSB 22-NA-151 and Service Update N222369401 be applied and documented on your repair order. Recurring episodes after multiple repair attempts may support a lemon law evaluation.
Yes. Two separate Technical Service Bulletins from GM address Super Cruise unavailability on the 2022-2023 Bolt EUV. The first (filed with NHTSA June 2022) affects 2022 model year vehicles and is caused by outdated map data files in the K179 Digital Map Control Module. The fix is a USB-based map data update performed at the dealer. The second (filed with NHTSA October 2023, DTC B126B) affects 2022-2023 vehicles and is triggered when the Wi-Fi Hotspot 'Share Hotspot' setting is turned off, which stops the vehicle from receiving map data updates and causes the 'Super Cruise Unavailable' and 'Service Driver Assist' messages. The fix involves toggling the Wi-Fi Hotspot setting and reprogramming the map module. Super Cruise is an advertised premium feature on the Premier trim. If your vehicle has been back to the dealer two or more times for Super Cruise failure without a lasting resolution, this pattern may support a lemon law claim for failure of a specific promised feature.
NHTSA recall 23E065 (September 2023) covers 9,423 Webasto portable Level 1 charging cords (part number 24044913) shipped with 2022-2023 Chevrolet Bolt EUV vehicles built before September 22, 2022. The defect: the cord contains incorrect software that may fail to stop charging if the ground connection is lost, creating a brief electric shock hazard when the cord is handled. The remedy is dealer inspection of the charging cord and replacement if the cord is the affected unit, at no charge. If you have not yet had this recall performed, stop using the portable Level 1 cord and contact your Chevrolet dealer to schedule the inspection. Your dealer can confirm whether your specific cord is the affected batch by checking the part number. Vehicles built after September 22, 2022 are not impacted by this recall. GM recall reference number is N2324073000.
You may. California's Song-Beverly Consumer Warranty Act presumes a vehicle is a lemon when the manufacturer cannot fix a safety defect after two or more repair attempts, cannot fix any other substantial defect after four or more attempts, or when the vehicle has been out of service for 30 or more cumulative days during the warranty period. The Bolt EUV battery fire defect went through three consecutive NHTSA recall campaigns — 21V650, 24V481, and 24V812 — spanning August 2021 through October 2024. Owners who returned to the dealer for ADS software re-installation under the follow-on recalls (24V481 or 24V812) accumulated additional repair visits on the same underlying safety-critical defect. Owners who were subject to mandatory charging restrictions (limiting charge to 90% or less) for an extended period may also have grounds based on substantial impairment of use. If General Motors failed to permanently fix the defect, you may be entitled to a repurchase at the original vehicle price (less a mileage offset) or a comparable replacement, with GM paying your attorney's fees. This is general information only, not legal advice — your eligibility depends on the specific facts of your case.
No. A 'cannot duplicate' or 'no trouble found' entry on your repair order still counts as one repair attempt under California lemon law. The manufacturer does not get a free pass simply because the warning light was not active when the vehicle was in the shop. For the Bolt EUV specifically, battery-related fault codes (P0BBD, U3636, P0A3F, P1B03) often appear only in stored or historical DTC memory rather than as active codes. Ask the dealer to print the full DTC history and attach it to your repair order. Also ask whether GM Service Update N222369401 and TSB 22-NA-151 have been applied. Keep every repair order — including CND visits — and note the exact date and mileage at each visit. That documentation is the foundation of a California lemon law claim, regardless of whether the dealer replicated the fault. A lemon law evaluation is free; speaking with an attorney before your next dealer visit can help you document the problem in the most useful way.
