I had no warning or indication whatsoever that my battery was going bad. I was at a major red light and my car shut down, then started back on its on with the entire panel lite up. The light changed and when I tried to turn I had hardly any stirring and almost no brakes. I almost ran into the car in front of me. I was able to get it into a parking spot and then it still gave me no light or notice of a battery issue. Because it had a recall on it that was repaired four days prior I had it towed to the dealership. They told me it was the battery but even when I picked up the car (for AAA to install the battery), it still showed 13.6% power on a 14 volt battery. This issue almost caused me to have an accident and caused me to waste $168 for a tow.

I am reporting a severe powertrain safety hazard involving my 2022 Chevrolet Blazer at approximately 69,000 miles. The vehicle's 9-speed transmission is experiencing a critical internal hydraulic failure that causes unpredictable and violent lurching. Specifically, there is a severe delayed engagement when shifting into Reverse. The engine revs without moving until the hydraulic pressure suddenly spikes, causing the vehicle to violently slam backwards and catch the gear. Furthermore, the transmission exhibits harsh and slipping shifts while driving forward, specifically violently jerking during the 2nd-to-3rd gear upshift. ​These exact symptoms align with widely documented hydraulic control and valve body defects in the GM 9T50/9T65 transmissions, which are known to cause harsh shifts, delayed engagement, and flaring between gears. Concurrent with these transmission failures, the ABS warning light illuminated. An independent shop misdiagnosed the severe drivability issue as a standard ABS fault, while a local Chevrolet dealership denied Goodwill assistance despite this being a premature internal transmission failure. ​This creates a severe safety hazard. The unpredictable lurching in Reverse endangers pedestrians and other vehicles in parking lots. Additionally, the violent shifting at speed creates a high risk of sudden internal component failure and a complete loss of propulsion while driving in active traffic.

"Steering Assist is Reduced, Drive With Care" showed up on the dashboard. The temperature gauge dropped to dead cold. Once the car was parked and cut off, the fan still kept running for 5 minutes. From my research it seems these are the signs of a thermostat being stuck open. It also seems this is a very common problem with this car, according to the internet. This vehicle has around 70K miles. There were no other issues prior to this failure.

I had the transmission serviced for its second serivce at 84705 miles just ten days before this happened. The first service occurred around 47k miles when I learned about this issue with Chevrolet transmissions.

As I accelerated after the traffic light turned green the vehicle stalled. I was able to move the vehicle to the curb on XXX [XXX] is a two-way road. The vehicle stalled while on an active road which could have led to my vehicle being rear ended causing potential injuries to myself and other drivers. The engine turned over and there was fuel in the gas tank, however, the vehicle wouldn't start. A warning light showed: "low battery", but since the engine was trying to start, it seems unlikely that the battery was low. A second warning light showed: "battery saving" mode. These lights appeared once the vehicle was parked on the curb of the road. The vehicle was towed to David Chevrolet, a GM dealership on [XXX] about 2 miles away.

My 2022 Chevrolet Blazer abruptly Shut down all power for about five seconds while I was stopped at a red light. The vehicle restarted after I pressed the push-button ignition, but the dashboard displayed a brake system error warning with no explanation of the cause or instructions for next steps. No other warning lights preceded the shutdown. The vehicle appeared to resume normal operation after restart, but the brake system warning remained. This appears consistent with complaints filed by other 2022 Blazer owners describing simultaneous electrical and brake system failures.
