2022 CHEVROLET BLAZER Complaints

Thermostat fails resulting in steering power reduced, temperature goes to C and fan runs overtime. This thermostat or temp sensor fails intermittently and fixes itself. Car could be overheating and you wouldn't know. This part is recalled on 2021 Blazers already.

I have a 2022 Blazer with a 3.6 engine. The thermostat has failed and dealer says only certain blazer vehicles are covered under aspecial warrnty exstesion. I know several people having the same problem.I have a check engine light, with a scan shows code P0128(thermostat0. I also have a display of power steering assist reduced and tempature gauge stays much lower than normal.. When you turn vehicle off the high speed cooling fans remain running ub=ntil battery is dead.

I have received this warning a few different times “Steering Assist is Reduced". Which causes my vehicle to not blow cold air when AC is on. Fans are louder than normal. And when I turn off my vehicle fans continue to run for roughly around 8 minutes.

My engine coolant temperature sensor failed. Replaced it and still not fixing the issue. This takes my steering assist away as they are all interlinked? I have seen on forms this is a common issue. This has the potential to blow up my engine, I’m not sure how this is not a recall with so many 2020-2026 blazer owners having the same issue.

My Drive Assist stopped working. Then my Air conditioning stopped blowing cold. Then the temperature gauge stopped working. Upon turning the car off the fan continued to run for several minutes. Took to repair shop where it required a new thermostat housing, coolant temp sensor and coolant flush. The total cost for repair was $1,131.52. The car has 37,000 miles on it. Barely out of warranty. This is a well-known issue among Chevy owners.

When shutting off the car, the fan continued to run. I started the car up again to see if this would allow the fan to turn off. No luck. The steering assist was dis-enabled on the dash. I took my car to the dealer to find out that it has a bad thermostat and that my radiator was leaking. The thermostat was covered but I had to use my extended warranty to pay the additional repair. My deductible for my extended warranty is $300.00. My daughter has a 2021 Chevy Blazer and the same situation happened. There was a recall and all her parts were covered.

Driving the vehicle when all of a sudden the engine shut off. All electrical systems continued to function. Luckily this occurred at low speed in a parking lot but had it happened at high speed on the freeway it could have been a huge safety risk. The vehicle was towed to a nearby automotive shop that diagnosed it as a bad fuel pump controller. There is an open GM recall that includes the 2021 Chevy Blazer (and a suite of other GM vehicles), but not the 2022 Chevy Blazer. I am concerned that the GM recall does not fully cover all of the vehicles that could be impacted by this issue.

Unknown…. Cut open my shin (leg) on the bottom corner of my driver’s door (black plastic side molding). That part is sharp! Required ER with 14 stitches on 9-24-25. As of today I’m still recovering.

Car is displaying a “Steering assist is reduced drive with caution” engine light is on and fan continues to run for 5-8 minutes after car is turned off. Was told by a mechanic it is a P0128 code, coolant thermostat. This is the third time it has happened in the last year. Other two times the codes cleared.

Incident Description: While my wife was driving our 2022 Chevy Blazer at approximately 40 miles per hour, the vehicle’s dashboard suddenly went dark and became unresponsive. Multiple warning lights illuminated simultaneously, including the check engine light, ABS light, and other system alerts. The dashboard appeared to flicker as though it was repeatedly shutting down and restarting. When the brake pedal was applied, it offered no resistance and traveled completely to the floor without slowing the vehicle. To bring the vehicle to a stop, my wife shifted into neutral and allowed it to coast until it came to a complete stop. Fortunately, there were no intersections or other vehicles in front of her at the time, preventing a potential accident. This incident raises serious safety concerns, as both electrical and braking systems appeared to fail simultaneously.
