Regenerative Braking

[2022] Same situation occurred twice. I was in the car at a red light. Car had been stopped for about a minute. Was on a slight decline, engine brake was engaged to hold car in position. Car was stationary completely. Suddenly tons of warning lights flash on the dash board 'One pedal driving unavailable', 'Service ESC', 'Service trailer brake system', 'Service active steering system', '4wd unavailab
[2024] During the morning drive, while in one pedal driving mode, the need to apply more brake due to a quick change of traffic lights occurred. The brakes felt hard and the vehicle did not feel like it was stopping as quickly as it normally would. When I parked the vehicle and exited no warning lights or other items were shown on the dash. Once I got back in the vehicle, a MIL light was lit and the "Ser
[2024] On August 11, 2025, at about 2:52pm, my vehicle was at a complete stop at an intersection awaiting the traffic light to turn green. There was a slight downgrade slope towards the intersection. The vehicle one-pedal driving was enabled. Weather was sunny with no wind or rain. Suddenly, the vehicle started vibrating violently and started rolling into the intersection. I pressed on the brake pedal b

Electric Propulsion

[2025] While driving on a public road, the vehicle suddenly shut down and rebooted itself. Motive power was lost during the event. This has happened at least a dozen times during normal driving, including while transporting a child. Video of an occurrence was recorded. The vehicle is a 2025 GMC Hummer EV with approximately 10,400 miles and has been in service about eight months. This creates a serious s
[2023] My 2023 GMC Hummer EV 3X has experienced repeated thermal-protection failures in the high-voltage battery and drive-motor cooling system, causing the vehicle to enter limp mode and drop to as low as 12 mph without warning. Stored fault codes: P0C12, P0C13, P2EE0, P2EE1 (battery and drive-unit overheating). A sudden, unannounced drop to 12 mph in a 9,000-lb EV is a serious safety hazard — on highw

"Battery-related" includes high-voltage propulsion battery, charging system, hybrid drivetrain, electric propulsion, regenerative braking, 12V auxiliary battery, and thermal-event complaints. Other complaints (suspension, steering, brakes, infotainment) appear in the engine and vehicle-level sections. Rates are absolute counts, not normalized per-VIN — high-volume models naturally produce more raw complaints than low-volume ones. Self-reported death and injury counts are capped per complaint to limit form abuse.
