2021 CHEVROLET BLAZER Complaints

2021 Blazer Message steering assist reduced ESC needs attention 15,000 miles shoukd no way need rack n pinion . Steering reduced and is a hazard to drive

On the way to work my car said “driver assist is stopping drive with care” about 2-3 times. Upon getting out of my car it sounded like my car was still running. I turned it off and on a few times and it still sounded that way. I had to go inside or I would be late so about 20 minutes later I was able to come back and check on it and the noise stopped. It was coming from the hood. Upon googling I figured it was something to do with a faulty temperature gauge which correlated with the signal from the car as well as the sounds. It seemed like this is a very common occurrence for these cars. I called the dealership and they said they fix these everyday and the man knew exactly what was wrong before I could even finish describing it. Unfortunately I don’t know the cost of this and have already had several other things to repair in my home recently so this will be detrimental to my finances if this isn’t covered. On the way home it did it again along with no AC in the 90 degree heat and then the engine light came on. We had to open the hood and leave the garage door open to prevent any possible harm that may do in the garage. This could be very dangerous for me as I drive my car everyday to work and can’t afford to rent a car for several weeks while this one isn’t working. And I’ve only had it for 6 months. Now my husband and I have ti figure out how we are each getting to work with one car until we get this fixed or we borrow a family members car.

The temperature sensor fails randomly. I can reset it by unplugging the battery but it will just drop off again in a week or two.

Temp stuck on cold, ac doesn’t work and driving assistance off. Fan runs after shutting engine off.

Midway home I got a message on my dashboard “steering assist reduced - drive with care”, but my power steering was still functional. I parked my car in the driveway, shut it off, and the cooling fans started blowing excessively. This continued for 5-ish minutes before shutting off on its own. Then I noticed that the engine temp gauge wasn’t working. Unsure if this is a problem with the thermometer or the sensor currently.

The temp gage stays on cool. Ac does not work and the radiator fan stays on after car shuts off. Dealership finds nothing wrong.

The steering assist stopped working. The defrost stopped working because the ac stopped working. The temp gauge stopped working. Error code P0128. I have since found out all this is caused by a faulty temp sensor.

"Driver Assisted Reduced Use Drive With Care Message" comes on when it is over 70 degrees outside. The temperature gage reads zero, A/C does not work, when the car is turned off the fan runs on high for an extended period of time. Showing code P0128 Used car purchase, came on 3 days after receiving vehicle from the dealership. Reset the code came on again 2.5 weeks later (5/3/2025) when the outside temperature was in the 70's

Took 2021 Chevy Blazer to a Chevy dealer for small leak. 25000 miles and dealer said I have a leak in the radiator and needs to be replaced. If I didn't notice the small leak the engine could overheat, and possibly start a fire.

The vehicle’s brakes failed while I was driving. I was luckily able to steer the vehicle off the road narrowly avoiding hitting another car. We had the vehicle towed to a Chevy dealer and they told us the fault was due to a low voltage battery. They would also not drive the vehicle until the battery was replaced because it was giving an error message of “brake system failure”. The dealer is the only place that has inspected the vehicle at this time. The warning messages appeared at the time of failure and not before. I find this to be a manufacturing defect in need of a recall as this could have easily caused harm or loss of life.
