2019 Chevrolet Blazer Recalls, Ratings & Complaints

Incident: October 6, 2026 · Filed: October 17, 2026

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.

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.

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.

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.
