2019 CHEVROLET BLAZER Complaints

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.

Engine temperature gauge is not working. Dash is displaying driver assist issue and steering intermittently locks up while moving. Air conditioning does not work and cooling fan is running at high speed. Thermostat and coolant temperature sensor need to be replaced. Such a high number of these vehicles are failing that i can’t even get factory parts

Nothing necessarily happened, but I've been getting the "steering assist reduced, drive with care" pop up, which assist I've been reading might mean a faulty thermostat. Sounds like a common issue and may e time for a recall? Only 60k miles on my blazer.

i was in a severe accident on 10/6/2025 with a vehicle traveling at approximately 50+mph. My front quarter panel was struck crossing an intersection when a vehicle ran a red light. My vehicle sustained a lot of damage with my head striking the drivers side window --- with no air bags deploying

The contact owns a 2019 Chevrolet Blazer. The contact stated that upon shifting to park(P) and attempting to turn off the vehicle, the message "Shift to Park" was displayed and an alarm sounded loudly. The contact stated that upon turning off and restarting the vehicle and shifting in and out of park(P) several times, the vehicle responded as intended. The contact stated that the failure had become a recurring failure. The dealer and the manufacturer were not notified of the failure. The vehicle was not diagnosed or repaired. The failure mileage was approximately 65,000.

Dashboard goes on like a Christmas tree (almost all lights turn on ABS GAS LIGHT TRACTION CONTROL PARKING SERVICE LIGHT) check engine stays on then disappears after a few days. Transmission won’t gear into shifts only stays in one shift.

My transmission is leaking fluid and has trouble going in reverse. This model Has had two recalls in 2020 and 2021 with the one from 2020 Was specifically for missing parts on the transmission causing leaks. My car is under the mileage for the transmission to even be a problem as stated by multiple mechanics. If there was a recall why wasn’t I informed before the transmission began to leak. The is serviced regularly by dealership where car was purchased. My safety is important to me but I guess not to CHEVROLET BECAUSE I MEVER WAS TOLD ABOUT A POSSIBLE ISSUE WITH THE TRANSMISSION. SO I HOPE YALL TAKE NOTICE AND DO THE RIGHT THING

Warning message flashes "put car in park" after putting it in park and pushing the stop button. It flashes for a few minutes, beeps the horn alert, and you can't lock it . It was diagnosed at a Chevy dealership as needing new switch and jumper harness at almost $800.
