    - Redding, CA

    Someone pulled out in front of me going 45 mph and totaled my car when they smashed into the front drivers side of my vehicle. My airbags didn’t deploy and no warning notifications or emergency braking ever occurred. This is dangerous and was severe enough to total my vehicle. My airbags should have deployed. No warning lights or any other issues when it occurred. It was inspected by insurance and determined a total loss.

    Shortly after purchasing my trailblazer in 2020 I noticed a glitch in the speakers where it would make a crackling noise (mainly when the car is off). it hasn’t been consistent when it happens, but since observing the issue I notice the issue happens most often when I close the trunk (by pressing the button on the trunk door.) no warning lights shows when this happens. Although this doesn’t seem to be a harmful safety issue, anything electrical can result to something more serious. I plan to bring this issue up at my next oil change at the dealership.

    The vehicle began to give the error Shift to Park when the vehicle was in park and after the power was shut off. Because of this I cannot safely turn off the vehicle because it cannot recognize it's in park and will run the battery down whenever I use the vehicle. This problem has been previously presented in other models manufactured by GM. I am taking the vehicle in for inspection at a local Chevrolet dealership on 9/24/22 at 8 am. This issue first started around the second week of September this year with one or two errors here and there. Now, it happens every time I drive the vehicle.

    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!

    3 times in the last year while we were driving the acceleration wen very high like from 50 to all of a sudden went up to about 80. I had to stand on the brake and try to pull over. Still accelerating I put it in park and shut it off. When you restart it it drive fine again. This has happened three times and the dealership says they can't find a problem. We are stuck driving a death trap. Please help. They wanna charge diagnosis everything I take it in. Then they say they can't find nothing. Now I am finding others that have had same issue and dealership says there is no problem. This has got to be destroying the engine reving at such high speeds.

    The brakes make squealing sound when coming to a stop. the dealer has acknowledged the problem and said there is nothing they can do about it and that the problem is normal. It is not normal for brakes to squeak every time the car stops.

    Second time in dealership shop to get gas smell coming from engine. Vehicle still under warranty. Afraid of the vehicle catching fire on me. Took it into another repair shop and 2 technicians notice the strong gas odor and was afraid of working on it.
