2025 CHEVROLET BLAZER EV Electrical System Problems

Multiple safety-critical malfunctions have occurred on this vehicle involving unintended braking, unintended acceleration, and false activation of driver-assist systems. These events did not happen at the same time and occurred under normal driving conditions. At various points, the vehicle has suddenly applied the brakes without driver input, including hard braking events that felt like an automatic emergency braking activation when no hazard was present. In separate incidents, the parking brake has engaged while the vehicle was in motion, causing abrupt deceleration. There have also been instances of unintended acceleration where the vehicle surged forward briefly without additional throttle input.

This creates a situation in which the driver must wait in the middle of the road after placing the car in drive before being able to close the garage door. In seeking solutions from online forums, some drivers have reported their Blazer EVs allow the button to be accessed while others report they do not, so I speculated perhaps I missed a software update, but per the car's OTA system, the vehicle's software is current as of the time...
