While backing into parking at a Humble Cow ice cream place. My 2025 Chevy Blazer EV AWD slammed to a stop. I was going 4 mph my spouses head hit the head rest and caused severe pain and stress. We had to go to the emergency room for treatment. This has happened 6 other times 3 since having the required updates and replacement of modules that took several months to complete. She was given medication and lytocain patches for the trauma of her neck and head. She is now afraid to drive in my vehicle. I looked up the situation and found on Reddit and the internet that this is a known issue with Chevy and several other vehicles relating to their braking and eboost system. One work around is to turn off all of the sensors from the settings menu to include parking. It also said to not use the one pedal driving. This is unattainable for a brand new car that I paid Cash $45-$50,000 for and not to be able to use it as intended. Please look into this. I will be filing another complaint with the dealership on 14 September 2026. Something must be done.

NHTSA complaint 117211191. Vehicle has a horrible squeaking sound coming from the brake pedal area. First dealer diagnosed it as the master cylinder needing replacement. Noise did not go away and GM said that it is normal. The noise is not normal and has never been on any other car I have owned. 2. When reversing, the car sometimes abruptly slams on the brakes as if it is avoiding a collision even though no collision is close to happening. GM refuses to fix the problem.
NHTSA complaint 11715633The contact owns a 2025 Chevrolet Blazer.

NHTSA complaint 11704188At a low speed, between 10 and 15 mph, the forward collision system automatically triggered and brought the car to an immediate stop. While we were lucky that no car was following behind us, the passenger and I experienced significant whiplash and lasting back pain as a result of this. The vehicle has not been inspected by anyone, and not been reproduced. The forward collision system flashed (red warning light, alert).
NHTSA complaint 11704018Multiple 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.
NHTSA complaint 11699144There 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.

NHTSA complaint 11691483My 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..
NHTSA complaint 11687679This 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.
NHTSA complaint 11684841At 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.
