CHEVROLET Complaints

Around 55,000 miles, my 2021 Chevrolet Blazer experienced a throttle body failure. The check engine light illuminated and the vehicle entered a reduced power/limp mode condition. Throttle response was significantly limited, and the vehicle could not accelerate normally. While the vehicle remained drivable, it took substantially longer to reach speed, which could pose a safety risk when merging into traffic or crossing intersections. Diagnostic trouble code P2101 (Throttle Actuator Position Performance) was present. A Chevrolet dealer confirmed an internal throttle body failure and replaced the throttle body assembly. This component is a critical engine control system, and failure could affect acceleration and vehicle control, posing a potential safety risk. The failure occurred well before expected service life and required a costly repair. The component has been replaced and is available for inspection upon request. I believe this may represent a premature defect and should be investigated for similar failures in other vehicles.?

turbo/superchargers malfunctioned, and I had to have it replaced back up sensors do not work properly. Say backup, assistant, malfunction.

Luggage and shudders at cruise speed, seems like auto transmission is coming apart. Paid $500 for the trans flush the service bulletin suggests but didn’t help, shop quoted a $8000 replacement on a vehicle with 60k miles. This should be a recall

Fuel gauge intermittently reports empty when vehicle was just fully filled with fuel

The tailgate on the truck popped open without being triggered to. This continued to happen like every 5-10 seconds. It drained the battery and was a hazard as I drive down the road.

At highway interstate travel speeds, vehicle was losing intermittent power. Exhaust at stopped, idle during trip smelled heavily of gasoline. White smoke blowing from exhaust with only 38k miles on the truck. Dealership is replacing the entire engine now and sounds like GM doesn’t want them to fully explore the cause of failure.
