Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering electrical on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
This engineering information (EI) will assist GM to recover a small number of electric vehicle battery packs from customer-owned vehicles in the field for further engineering study and analysis.

The failure pattern owners describe
Owners report two distinct electrical failure patterns on the 2020 Bolt EV. The first and most prevalent is high-voltage battery degradation and failure tied to recall campaign 21V650000 (issued August 2021). Owners describe reduced charge capacity, "Propulsion Power is Reduced" warnings, inability to charge above 80%, sudden immobilization, and spontaneous fire while parked or charging—sometimes within months of a battery replacement done under the same recall. Several owners report the software fix (which limits charging to 80%) has persisted for years without replacement battery availability, leaving them with roughly 50% effective range loss.
A secondary cluster involves unexplained electrical faults affecting charging systems, display screens, and vehicle controls. Owners cite charging port damage and fusion (one case involving a third-party Level 2 charger), intermittent blank dashboard screens, seat heaters and high-beam headlights engaging on their own while driving, and sudden loss of propulsion without warning or error codes. Some report the vehicle becomes inoperable with doors locked and windows trapped shut after electrical shutdown.
A third pattern involves camera system failures (rear mirror camera, backup cameras) that black out after rain and occasionally overheat to dangerous temperatures. One case involved a headlamp shutter mechanism failure after a pothole impact, requiring a $1,100+ replacement due to poor solenoid pin retention in the sealed assembly.
Across narratives, owners express frustration that replacement parts remain unavailable years after recall issuance, leaving vehicles restricted or inoperable pending repair completion.

Failure modes owners describe
High-Voltage Battery Degradation and Failure
High-voltage battery loses capacity, fails to hold charge, or stops functioning entirely—often after prior battery replacement under recall 21V650000. Vehicle displays 'Propulsion Power is Reduced' and 'Service Vehicle Soon' warnings, or becomes completely immobilized. In multiple cases the battery has failed within months of replacement, and owners report the vehicle catching fire while parked or charging.
When: Reported as soon as miles into a battery replacement (65 miles in one case), or months/years after prior battery replacement. Charging failures occur after overnight charging attempts or while parked.
Symptoms owners cite: Propulsion power reduced warning; Service vehicle soon warning; Inability to charge above 30–80%; Vehicle will not start; Loss of range (100 miles effective range when rated 259); Vehicle exploded/caught fire while parked or charging; Battery overheating while charging
Codes mentioned: N232421260 (False DTC Causing Unnecessary Battery Pack Replacements), NHTSA Campaign 21V650000 (Electrical System), NHTSA Campaign 24V812000 (Electrical System)
Repairs/costs cited: Battery replacement required; however, replacement parts have been unavailable for extended periods (18+ months reported). Interim remedy is software reprogram limiting charge to 80%, which persists for years without final remedy. One replacement battery failed within 65 miles; another failed within two years of replacement.
Recalls/TSBs owners mention: Recall 21V650000 issued August 20, 2021; temporary fix is software reprogram reducing charging to 80% (implemented mid-2023 at some dealers). GM has cited parts unavailability repeatedly. Some owners report GM denied repurchase claims despite prolonged immobilization. Recall N212345944 and N232421260 reprogram attempted with mixed results.
Charging Port and External Charger Damage/Thermal Failure
Third-party Level 2 charger (Mustart SAE J1772) overheated and melted, causing damage to the vehicle's charging port. The charger fused to the port and became so hot plastic burned and oil leaked into the vehicle's charging system. Vehicle became locked and immobilized with charger still attached. GM blamed the owner for user error and refused warranty coverage.
When: During active charging session
Symptoms owners cite: Smell of burning plastic; Oil leak from charging port; Charger plug overheated and melted; Charging port charred and fused to plug; Vehicle locked with charger attached, unable to shift out of park; Vehicle beeping with charger issue warning
Repairs/costs cited: Vehicle charging port required repair by licensed technician at dealer. Mustart charger melted. Owner reported damage but GM refused warranty claim, alleging user error.
Recalls/TSBs owners mention: GM refused warranty repair, claiming user error and abuse caused the loose connection and short circuit.
Intermittent Electrical Faults—Unintended Device Activation and Loss of Control
High-beam headlights and seat heater engage independently while driving with no manual input or warning light. Vehicle will not respond to manual attempts to disengage. In another case, the vehicle stalled at low speed with check engine and check gear shifter warnings; unable to restart. Negative 12V battery cable short-circuited. A third case reports sudden buzzing under dash, vehicle shutdown, locked doors, non-functional windows, inability to restart or unlock doors, and burning wire smell—trapping occupants in the vehicle.
When: While driving; while parked; at gas station
Symptoms owners cite: High-beam headlights activate on their own; Seat heater engages on its own while driving; No warning lights before activation; Manual controls fail to disengage features; Check engine warning light; Check gear shifter warning light; Vehicle stalls during low-speed operation; Unable to restart; Buzzing sound under dash; Vehicle shuts off while parked; Doors lock and windows trap occupants; Burning wire smell
Codes mentioned: NHTSA Campaign 21V650000
Repairs/costs cited: Power inverter module replaced under warranty in one case (March 2023). Reprogramming done ($400 out of pocket, December 2024). Negative 12V battery cable short-circuit replaced in one case. One vehicle required engine harness replacement ($1,500, not covered under warranty).
Recalls/TSBs owners mention: Dealer unable to duplicate failures in multiple cases; vehicle not repaired. One case referred to dealer service; manufacturer cited parts not available for recall repair.
Dashboard and Display Screen Electrical Failure
Both instrument cluster display (behind steering wheel) and center infotainment screen go completely blank—appearing unplugged. Screens unresponsive to ignition cycling. In past instances, issue cleared after charging or time. Most recent occurrence required 6–7 restart attempts with 5-minute intervals to restore function. No warning lights illuminate.
When: Intermittently; after recent car wash (mentioned one case); on rainy days (one case); at gas station parking lot (another case)
Symptoms owners cite: Both display screens completely blank; No speed, warning, or turn signal information visible; Screens unresponsive to ignition on/off; Issue intermittent but recurring over years of ownership
Repairs/costs cited: No repair completed by dealer. Issue resolved on its own after multiple restart attempts and charging overnight.
Recalls/TSBs owners mention: Dealer suggested humidity from car wash may be cause; advised against use of automatic car washes. No recall or service bulletins mentioned.
Rear Camera and Mirror Assembly Overheating and Blackout
Rear camera mirror display blacks out intermittently, then completely. Wiring harness re-seating, replacement, and camera replacement all performed without lasting fix. Mirror assembly overheats to dangerous levels—too hot to touch safely. Dealer unable to diagnose and extremely delayed in scheduling inspection.
When: Intermittent initially; became worse over one week; subsequent shutdowns occur regularly
Symptoms owners cite: Black screen on rear camera mirror; Assembly shuts down intermittently; Extreme heat buildup—nearly burning to touch; Issue recurs after component replacement
Repairs/costs cited: Wiring harness re-seated (no fix). Wiring harness replaced. Rear camera replaced. Issue recurred despite all repairs.
Recalls/TSBs owners mention: Dealer unable to diagnose; extremely delayed in scheduling further service (one week-plus wait cited).
Headlamp High-Beam Shutter Mechanism Failure
Bi-xenon HID projector system with mechanically actuated shutter controlled by solenoid. Pothole impact (1/4 wheel size, 6–12 inches deep, at 35–40 mph) caused solenoid metal pin to detach from shutter control arm, preventing shutter actuation and disabling high-beam. No mechanical retention on solenoid pin; design appears inadequate for routine road impacts. Owner repaired using tar/gum substance to retain pin.
When: Immediately after pothole impact
Symptoms owners cite: Front high-beam headlights disabled on side of impact; Solenoid pin dislodged from shutter control arm; Vehicle failed state safety inspection
Repairs/costs cited: Recommended repair: full headlamp assembly replacement, ~$1,100 + labor (sealed unit). Owner self-repaired using tar/gum compound to secure pin in place.
Recalls/TSBs owners mention: None cited; issue treated as impact-related, not manufacturer defect.
Sudden Transmission/Propulsion Loss and Limp Mode
Vehicle unexpectedly shifts into neutral while driving and enters limp mode, unable to accelerate above 45 mph. 'Conditions Not Correct For Shift' warning displayed, preventing return to Drive. Multiple occurrences: first in March 2023 (power inverter replaced), second in December 2024 (reprogramming), third in March 2025 (engine harness replacement recommended but not covered under warranty). Each occurrence requires roadside towing.
When: While driving at normal speeds; occurred while approaching intersection and while traversing intersection
Symptoms owners cite: Vehicle shakes then shifts into neutral; Warning: 'Conditions Not Correct For Shift'; Limp mode engaged; Unable to accelerate above 45 mph; Unable to shift back into Drive
Repairs/costs cited: Power inverter module replaced under warranty (March 2023). Reprogramming performed ($400, December 2024). Engine harness replacement recommended for third occurrence (~$1,500, not covered under warranty).
Recalls/TSBs owners mention: Covered under warranty for first repair (power inverter). Second repair (reprogramming) charged $400 out of pocket. Third repair (harness) denied warranty coverage.
