Several times now my Automatic Emergency Braking has kicked in, my car jerked me so hard that I just missed hitting my face on the steering wheel. This is the scariest thing in that moment, and it has happened when I have so much distance from the other cars so it’s very unexpected when it kicks in. Not to mention it makes like a grinding sound each time it happens. Again, this has happened several times before this last time. This is something that can easily turn in to a safety problem, not only does it make the car slide a little during this period—- but it also scares the person operating the vehicle because of the unexpected times that it happens. With no warning and safe distance between me and another vehicle it still happens.

What 2019 Chevrolet Blazer owners say
Most recent owner complaints, unedited.
Steering assist reduced message appeared Check engine light appeared, po128 code, thermostat and sensor defect. Common problem with these vehicles, GM has only recalled 2021 model even though the same engine and thermostat are on all V-6 models. Contacted GM, no assistance available on my year Blazer.
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.
