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.

The thermostat has been sticking, and needs to be replaced after only 30,000 miles.

Was getting a steering assist reduced error code. Auto stop quit functioning and air conditioning stopped cooling. Engine sounded like a jet. P 0128 thermostat error code came up and had to be replaced. I see lots of similar complaints. Cost me $700.

Shift lever to Park Alert on dashboard. Paid to have shift lever replaced on Blazer. Also had same problem on 2018 Malibu..paid myself to have shift lever replaced! I was NEVER NOTIFIED about a Class Action suit. I believe this is a MAJOR PROBLEM on GM vehicle. NEED GM TO HAVE A RECALL!

Steering assist reduced message, then no AC, temp gauge stuck at Cold, P0128 error Code.

We are noticing the coolant meter seems to be stuck on C, the AC is not blowing cold and we are getting a message that ACTION REQUIRED steering assist is reduced, drive with CAUTION. Today the brakes slammed on by themselves and almost sent my wife thru the windshield. Luckily she was in a clear area with no other cars around.

The thermostat is stuck open and needs replaced. If left as it is, could create overheating issues for the engine and even more damage. A service engine light was illuminated prior to finding the issue. The light was accompanied by a warning about assisted steering. Two days after the light first came on, a Chevrolet service department diagnosed the problem and is repairing it. An invoice can be provided at a later date once repairs are completed.
