What owners wrote

“Shift to park message on display when car is already in park, preventing the car from turning off completely draining the battery completely.”

“After the vehicle has been put into parked and attempted to shut off, a message displays “Action Required Shift To Park”. Although the vehicle is in parked there is some kind of sensor that is not reading it is in park. Vehicle first started doing this when parked on an incline but frequently happens since the first occurrence. One temporary solution is to shift into different gear or shake the gear shift.”

“My vehicle has been throwing an error code related to the thermostat. The temperature gauge will remain on C resulting in the fan running loudly, the air conditioner not cooling the cabin of the vehicle well, and a message displaying "steering assist is reduced drive with care". When I check the fluid levels everything is fine without issue. I'm VERY frustrated and want to get rid of my Blazer ASAP.”

“The backup camera in my preowned 2020 Chevy Blazer RS stopped operating within 7 months of purchasing Jan 13, 2024. It was replaced by local dealership. However, less than two weeks, it stopped working again. It's a safety feature that's not operational concerned may lead to accident. I did some research online where other owners have experienced the same problem.”

Should you keep driving it?

This page can't tell you that. 0 of 27 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.

File your own report with NHTSA. Complaint counts are how a problem gets an investigation.
