2019 Chevrolet Blazer

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.

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.

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.

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
