Shift to park displays on dash when put in park after I turn the car off. Have to turn the car back on shift from park to drive several times before it finally goes off. Something going on with backup camera when backing up it not always comes up on interior display monitor. The outlet in the console dc outlet not working had it looked at several times the mechanics can't figure out what the issue is all fuses are good And a few times couldn't stat the car after shift to park display pops up had to try several times before it started. Can't understand why GM hasn't ordered recalls on these matters and I'm sure I'm not the only one dealing with these issues. It's a same that in 2026 dealing with issues that I have to pay out of pocket to try to find out what is the problem is.When GM knows these issues are the with the 2019 Chevy Blazer. GM needs to start addressing the issues my car wasn't a cheap car I pay a high price to have the issues that I have .

Electronically controlled thermostat and sensor fail or get stuck at a much lower coolant temperature causing the dash to display the “steering assist is reduced drive with care.” It isn’t just a message, the steering is much harder to use potentially causing an accident. The ac completely doesn’t work causing potential for sensitive, elderly, or young children and pets to overheat inside, it’s significant risk of injury or death from the hot summer temperatures. The engine coolant temperature gauge is all the way down on C position which isn’t registering how hot/cold the engine gets potentially causing damage to the vehicle and a total loss of the vehicle entirely due to damage from the engine overheating. After doing research online, this problem is affecting all years of the 2019+ blazers with the 3.6L V6 engine AND other known problems with other models and years of their other lineup of cars, it’s very widespread across their platforms. So what are people supposed to do when it isn’t? Pay an $3800+ repair bill to GM when they KNOW it’s more widespread than just this year/make? This is a scam. I’m reporting this complaint to raise awareness and hopefully GM will do the right thing.
- Electrical system · Structure › Body
Driver's side floorboard floods during rain, dripping water under the dashboard directly onto the accelerator and brake pedal. Trapping water and trapped moisture has caused severe mold buildup throughout the interior, creating respiratory hazards and window fogging. This matches GM Technical Service Bulletin 23-NA-087.

The contact owns a 2019 Chevrolet Blazer. The contact stated that while starting the vehicle, there was a strong odor coming from the vehicle, and no warning lights illuminated. The contact also stated that a "Shift to Park" warning message displayed while the vehicle was already in Park, requiring multiple shifting attempts to clear the message. The vehicle was taken to a dealer, where it was diagnosed that the radiator had failed and needed replacement. The vehicle was repaired. The contact was informed that the radiator issue was a known failure that could recur. Additionally, an inspection revealed that the rear tow hook had failed and needed replacement. The vehicle was repaired. Regarding the shifter failure, the contact was informed that the failure could not be duplicated. The manufacturer was not notified of the failure. The failure mileage was approximately 22,000.

I was driving into a parking lot when my back passenger side window imploded like a rock was thrown at it, but no rock and nobody in sight. I looked all around for a cause but believe it somehow spontaneous shattered. Thankfully 3 minutes prior I had dropped my kids at school otherwise there would have been injury I am sure.

Electronically controlled thermostat and sensor fail or get stuck at a much lower coolant temperature causing the dash to display the “steering assist is reduced drive with care.” It isn’t just a message, the steering is much harder to use potentially causing an accident. The ac completely doesn’t work causing potential for sensitive, elderly, or young children and pets to overheat inside, it’s significant risk of injury or death from the hot summer temperatures. The engine coolant temperature gauge is all the way down on C position which isn’t registering how hot/cold the engine gets potentially causing damage to the vehicle and a total loss of the vehicle entirely due to damage from the engine overheating. GM sent out letters to 2021 blazer owners which included a special coverage number N252508350 applying to people with this year having this problem and they have until 2036 or 150,009 mi to get the repairs made free of charge, they just bring the document with the special repair codes to the dealer and they fix it free of charge. After doing research online, this problem is affecting all years of the 2019+ blazers with the 3.6L V6 engine AND other known problems with other models and years of their other lineup of cars, it’s very widespread across their platforms. So what are people supposed to do when it isn’t the 2021 year? Pay an $800+ repair bill to GM when they KNOW it’s more widespread than just this year/make? This is a scam. I can’t even do the repair myself because I’m having trouble finding the correct parts online and not only that the repair is extensive, the whole top half of the engine needs to be taken apart just to get to the thermostat, we’re talking the airbox and intake manifold, all the plastic parts and shrouds and sensors covering engine, the fuel rail and injectors, pipes and clamps, engine coolant needs drained and refilled. It’s a major fix. I’m reporting this complaint to raise awareness and hopefully GM will do the right thing.
- Steering
Power steering goes out intermittently while driving.
- Vehicle speed control
The transmission or torque converter has slippage and shuddering that has caused one or both to go bad. My safety was at risk due to this item beginning to fail to cause the inability to accelerate to maintain my position in traffic. The problem was recreated for the service technician. There was no warning or indication before this became an issue.

The vehicle will not shut off when you shift to park. You are forced to sit in the vehicle for extended periods of time attempting to get the vehicle turned off. Apparently Chevy is familiar with eat problem and there are pending class action law suits in Ohio. According to the dealership Chevy has acknowledged there is a defect but no recall has been issued. We have had this issue for about two months and it is getting worse.

Shift to Park issue: Known issue where the car fails to recognize it is in Park, preventing it from shutting off. Electronics: Potential blanked-out display screens, USB port issues, and malfunctioning cameras. Steering Assist: Restricted, temperature gauge goes to cold and radiator fan blows hard. I have to unplug negative cable to battery and reconnect and everything goes back to normal.

2019 Chevy Blazer. Car would not turn off the electrical components when parked. Put car in park and walked away and there is a warning note that says, "Shift to Park." But the car was in park. Called Chevy and they know about the issue on the 2019-2023 vehicles. They sent me the Technical Service Bulletin. Back in 2020, the car had the shifting harness and button replaced and we just had to have it replaced again because it is a consistent issue with the vehicle. Except this time, the dealer charged us $668.40 to fix it! It is a known issue by the company and THEY sent me the service bulletin to get it fixed. It should have been covered by Chevy, or, at least a recall should be instituted. The power to the car wouldn't shut off. We were able to jump the car to get it started again.

I believe my thermostat is a problem. I keep getting "P012B" "coolant under operating temperature" codes on my obd2 meter. This seems to coincide with "driver assist reduced" on my instrument cluster on my dash board. I researched it and on a forum it sounds to be a very common problem.…
I believe my thermostat is a problem. I keep getting "P012B" "coolant under operating temperature" codes on my obd2 meter. This seems to coincide with "driver assist reduced" on my instrument cluster on my dash board. I researched it and on a forum it sounds to be a very common problem. Someone said to report it on here. I can clear the "p012b" error code with my obd2 and my thermostat instantly becomes responsive however it comes back within 2 days or so.

Faulty thermostat. Check engine light comes on due to thermostat getting stuck open and needing to be replaced. This is terrible for the engine and the environment.

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.
