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. These malfunctions appear to be related to electrical or ADAS system faults affecting braking logic and propulsion control. No warning lamps or messages reliably appeared before these events. The issues pose a serious risk to the safety of the driver and others because the vehicle’s behavior is unpredictable and can interfere with safe control. The dealership was unable to reproduce the conditions during inspection, but the incidents have occurred multiple times in real-world use.

There is a really bad rattling noise that comes from the dash. The dash at the windshield you can push down very easily. Whem driving on rough road the ratteling noise is very loud and distracting. During daylight driving you get a very bad glare from the dash board in the windsheild. I havent found a dash mat yet to fox the problem temporarily but some people have mentioned trying felt.

My windshield is defected with no real time when a replacement can be ordered..the interior lining is not sealed properly which is causing a buckling effect by drivers and passengers visors.. Rain is getting inside and soaking into the dashboard causing the electrical system on screens to blink in and out Finally my brake harness is still on recall and my car has been shifting into park which could cause severe problems if I am on the highway..

This is a report of defective software that could increase the chances of an accident, injury and or death. This vehicle features a built-in garage door remote which is utilized exclusively through the touch screen. However, when the vehicle is in reverse the backup cameras restrict access to the needed menu. After backing up and putting the car in drive there is a delay before the back up camera turns off. 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 of this submission. I have recorded a video that I am happy to share , however it exceeds the size limit allowed for uploads in this report.

At certain times of day it is nearly impossible to see through the windshield as the glare from the dashboard reflection is very bright. The attached pictures do not really show the extent of the glare.

The contact owns a 2025 Chevrolet Blazer EV. The contact stated that while driving at various speeds, there was a clicking sound coming from the front suspension of the vehicle, and the vehicle was difficult to drive in a straight line or turn in either direction. The vehicle was taken to the local dealer, who was unable to determine the cause of the failure. The vehicle was not repaired. The contact was informed that the vehicle could not be repaired, and a buyback was offered for the vehicle. Additionally, while driving at an undisclosed speed, the Forward Collision Avoidance system erroneously activated, causing the vehicle to abruptly stop in the middle of the road. The vehicle was taken to the local dealer, who reprogrammed the Forward Collision Avoidance sensors, but the failure persisted. Additionally, the charging port had malfunctioned and became inoperable. The charging port was replaced, and the vehicle was repaired. The manufacturer was notified of the failure.

The motorized charge port door no longer opens. There is no manual operation rendering the vehicle unable to charge. This presents a potential hazardous situation if the error occurred during a road trip where there are greater distances between charging stations and services. GM customer service and OnStar could not resolve the issue when contacted.
