CHEVROLET Complaints

My vehicle is having an oil consumption problem. 2 quarts were missing from my oils consumption test. The dealer is now doing a secondary oil consumption test and I’ve read up and learned that there have been a lot of recalls with the engine and oils changes.

Afm lifters has failed in my vehicle 3 times as of date. Being that its a costly repair this should be recalled. Information provided is the latest mileage.

While pulling a 14' enclosed trailer when i left off the gas pedal there was a sudden low growl/vibration coming from the bed area of the truck. I was slowing down for a red light and it started at around 20mph. I pulled off slowly when the light turned green and was listening with my head out the window but everything seemed normal, about 2 miles down the road from the initial vibration/growl incident and running about 40mph the rear differential completely locked up causing the drive shaft to snap off the pinion yoke and left me sideways in the middle of both lanes with an enclosed trailer and alot of ticked off people cussing at me like i did it on purpose or something. Because the rear end was completely locked up, there was no way for me to move out of the road way so i had to sit blocking both lanes for 2 hours while waiting for a tow truck. There was no warning lights, the only kind of warning was the quick and subtle vibration/growling noise at the redlight.

The shift-to-park sensor in my 2019 Chevy Blazer RS is malfunctioning. After shifting into park, the vehicle does not detect that it is in park and displays a “Shift to Park” message. The issue is/has been ongoing and now it is almost impossible to bypass with wiggling the shifter. Safety Risk: The vehicle cannot be fully shut off or locked, increasing the risk of battery drain or unintended movement. This poses a safety risk if the vehicle is left in public or on an incline. Inspection History: The vehicle was taken in to the dealership in November/December 2025 due to MULTIPLE Warning Lights: “Shift to Park”, "Steering Assist", "Stabilink" and the usb-C charging port under the radio screen will stop working all together when this happens as well. This started around September 2025 and has occurred regularly since.
