2025 Chevrolet Blazer EV Problems

Attempting to merge into another lane today. Collision warning emergency breaking triggered and break checked the vehicle behind me. Almost caused me to be rear ended by the vehicle behind me.

I was driving down a road. Vehicle slammed on the brakes and then accelerated in it own causing me to hit a guardrail.

I was driving down a road. Vehicle slammed on the brakes and then accelerated in it own causing me to hit a guardrail.

This is now the second report from this vehicle with similar issues. This incident happened when in reverse with nothing behind me, the vehicle slammed on its brakes. No audible warning in the vehicle and nothing showing on the dashboard. The vehicle just applied emergency braking. This was a witnessed event.

See attached document for complaint.

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.

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..

The contact owns a 2025 Chevrolet Blazer. The contact received notification of NHTSA Campaign Number: 25V433000 (Parking Brake); however, the part to do the recall repair was unavailable. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The dealer was contacted and diagnosed that the windshield was not installed properly and needed to be replaced. The contact stated that while raining, water leaked into the vehicle through the windshield onto the dashboard. The contact stated that the seal had detached on the passenger’s and driver’s sides of the vehicle. The contact stated that while driving at an undisclosed speed, the vehicle shifted into park(P). The vehicle had to be turned off and restarted to shift out of park(P). The failure had occurred while driving, idling, and while parked. There were no warning lights illuminated. The dealer also discovered that the hood of the vehicle and the windshield were not flush, causing a slight detachment. The vehicle was not repaired. The manufacturer was made aware of the failures; however, no assistance was provided. The failure mileage was approximately 3,000.

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.

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 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.
