Sample complaint excerpts
Charging System
- [2024] There is a defect in the motorized electric charge port door. When you press the button it rarely works to open the charge port door leaving me with unable to charge my vehicle. I fear this will leave me stranded and my only course of action will be to rip the door off in anger. Many others are experiencing this issue. Chevy needs to address this.
- [2024] This is the 2nd time I have been left stranded unable to charge my vehicle due to the charge door malfuction on the vehicle. This is a safty issue due to the fact that if you are unable to charge the vehicle, you can get starnded somewhere unsafe putting yourself and family at risk. This charge door failure has happened once within 8 months after purchasing the vehicle, the charge door was replace
- [2025] The Telematics Module failed and is on backorder. This is a known issue across the U.S. This makes it so OnStar doesn't work and I am paying for it. Not just that the safety concern of it not working. GPS, Maps, Level 3 Tesla doesn't work. Car is really not usable as we can't charge on a level 3 when going over 100 miles. We have loss access to navigation, Google Built-In services, the myChevr
Regenerative Braking
- [2024] I’ve had intermittent issues where the one pedal driving feature would disable itself. Last night I narrowly avoided a T-bone collision as the OPD deactivated and as I approached a junction it took me a second to realize the car was not stopping and it was only by sheer luck that the other vehicle stopped abruptly so we didn’t collide.
- [2024] While this vehicle was in motion the brakes suddenly stopped working. The brake pedal went to the floor with no braking. The screen read brake assist failure. Safety was at risk due to being unable to stop the vehicle until it slowed itself down. This could have resulted in a fatality. The vehicle is available for inspection upon request. The vehicle was towed to the dealership today and no answer
- [2024] Although the owner's manual specifically states "When enabled, One-Pedal Driving applies in R (Reverse) and D (Drive). This feature remains enabled until manually disabled by the driver." One pedal drive does not work in reverse. Car does not creep in reverse like an ICE vehicle, but quickly lurches backward, surprising an experienced or forgetful driver and possibly endangering pedestrians walk
High-Voltage Battery
- [2024] This vehicle massively underperforming based on what was told to me at the time of sale (250–300-mile range), I have never come even close to that range. I am averaging about 125 miles using about 70% of the fully charged battery. I WAS informed that during colder temperatures I would experience faster battery degradation but it was not mentioned that it could be as dramatic as losing 50% of my ra
- [2024] On multiple occasions the electrical system of my car has gone completely haywire. Various error messages display on the dash referencing problems with almost all car systems including: high voltage battery warning, reduced acceleration, power steering failure, and others. These error message occur in conjunction with the display screens flickering, all the fixed dash warning lights coming on, and
- [2024] The Lithium-Ion Battery is not performing as expected. An issue has been detected in the Onboard Charging System which manages your vehicle's battery pack charge level.
Electric Propulsion
- [2024] My 2024 Chevrolet Blazer EV AWD has experienced two separate incidents involving sudden loss of propulsion without warning. First Incident – XXX While driving in [XXX], the vehicle suddenly lost propulsion without warning while I was in a turn lane in front of a medical center. Following the loss of propulsion, the Driver Information Center displayed warnings associated with the AWD system, shift
- [2025] Complete and total failure of the telematics module resulting in loss of self driving, onstar, WiFi, gps, and all connected services. Severe battery drain due to module forcing the vehicle to completely shut down while driving, resulting in loss of power steering and brakes.
12V Auxiliary Battery
- [2025] 2025 Chevrolet Blazer EV AWD purchased 5/23/25 (under 3,100 miles) The vehicle's Telematics Control Module (TCM) has failed, disabling the built-in navigation system, OnStar services, remote start, and My Chevrolet app connectivity. The dealership confirmed the TCM needs replacement and the part is on backorder with no ETA. This is a known issue affecting this model. I am reporting this as a saf

"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.
