I have had the 2021 chevy Trailblazer since may 2021, it has been 15 months, not even a year and a half off the lot and I have had wayyyy too many problems. I have has service the stabilitrak stability control system, service the antilock breaking system multiple times within the first 8-10 months. I had to get a part replaced due to that. The dealership had my vehicle literally for a month after I bought it, had an open tak report through gm due to my engine light coming on. Gm did not know why it was happening. Had 2 service engine and transmission system alerts. I have had a fuel injector and line replaced as well within the first 6 months. I have had to get the system updated 2 times also. Now August 2022 im having service battery, or starter. Have had my vehicle shut off on me at an intersection then come back on two different times. My breaks have been squealing ever since I got this vehicle. Dealership confirms everything is in good standing. I have not had a vehicle where breaks squeal when I am coming to a stop or backing out of my driveway constantly. Dealership keeps saying OH its just probably dust or dirt, spray them out and it should stop. But, it has not for about a year now! unbelievable! I am going it to trade this vehicle in. This is wayyy too much to be dealing with when you pay $30 grand on a vehicle!.
