36 Electrical System problem of the 2024 Chevrolet Trailblazer

Failure Date: 10/05/2024

This is an update for complaint # 11619009 after doing some online research and discussing with the service manager at my dealership, we identified a simple issue- apparently there was a problem with the torque used in connecting the ground wire for the electrical auto start-stop feature, which is what cause my vehicle to completely die and not be able to be restarted. After it was identified, it was corrected within minutes. I highly recommend that there be a service bulletin for any purchasers/lessees of the new 2024 Trailblazer (and possibly other chevy vehicles) to have the grounding issue checked.

38 Electrical System problem of the 2022 Chevrolet Trailblazer

Failure Date: 09/16/2024

For about a month now my vehicle is telling me to put it in park when it is already in park. Have to restart multiple times and go through all the gears put it back in park turn it off and still get the "shift to park" error. It does not happen every time I use my vehicle, but it happens so much I am unsure if it is safe to use. Even though it shows it is in park I wonder is it really? I have called the dealer where I purchased it for them to look at it and they will not even schedule an appointment because they say the parts are on back order and they have no idea when they will get them. This is the first brand new car I have purchased and after having a lot of secondhand vehicles I went back to chevy. I am very disappointed in chevy it only has 23000 miles on it, and they are not doing anything to fix this, I would not recommend chevy/GMC to anyone.

39 Electrical System problem of the 2021 Chevrolet Trailblazer

Failure Date: 09/10/2024

After placing the vehicle in park I get the “shift to park error”. I can’t leave the vehicle, or lock it. It can take any where from 5 to thirty minutes for it to actually read the shift. My car is now not reading my key 80% percent of the time. The vehicle turns off while driving down the road. Saying no “remote detected”. The key has been locked in the car twice. Which should be impossible. I’ve been stranded outside of my vehicle at night in atlanta for long periods of time. Trying to get the vehicle to unlock because it is not reading the key.

05/29/24 I took this vehicle to cronic Chevrolet in griffin, GA due to check engine light being on. Code detected purge pump it was still under warranty at that time only had 43,906 miles on had to get the purge pump replaced. Several weeks after getting it back I kept getting a shift to park message come up when trying to put it in park then started having trouble getting it to go into drive. I have had so many close calls from people almost bashing into me because my car will not go into drive and you constantly have to switch in and out of gears for it to finally go in. Its sucking the had right out due to it not shifting gears properly. The code reader detected transmission control module which I find to be faulty and understand there are serval recalls on this specific vehicle , when it started this issue it didn’t even have 50,000 miles on it!.

46 Electrical System problem of the 2021 Chevrolet Trailblazer

Failure Date: 07/01/2024

I first noticed an issue about a year ago when an electrical blaring noise was coming from my speakers followed by popping and crackling noises. I have taken my car into the dealership several times without resolution. Since then, I have noticed excessive humidity in the vehicle and recently found the trunk was flooded. I took the vehicle in to the dealership again, and they say the interior fabric is compromised now and the electrical sounds I was experiencing are coming from electrical damage inside the body. I have now read another review online from someone who had the exact same experience with this make and model. I believe this is a safety hazard to drivers who are unknowingly driving around for months in a vehicle that could be flooding and could cause severe damages like in my case. I have documents to support these claims, but I do not have electronic copies. If someone reaches out to me I can provide hard copies.

50 Electrical System problem of the 2022 Chevrolet Trailblazer

Failure Date: 04/18/2024

We own a 2022 chevy Trailblazer and we have experienced the “shift to park” issue more times than we can count. We receive the “shift to park” message on the dash screen after the car has been shifted to park and we attempt to turn the vehicle off. This problem has caused me to be late to my job on numerous occasions and late to an exam that determines my graduation at school. Many users report being able to just shift through the gears a couple times or wiggling the gear shift and it shuts off, but that is not always my case. I have, on a few occasions now, had to remove my gear shift knob and panel completely, locating the park switch and manually bending it to recognize that my car was in park. Doing this will typically subside the issue for about a week, but no longer than that. We have tried to have the dealership see the message when taking it in for other things, but it never seems to happen when they are watching. There were no other issues with this vehicle before this started happening. We purchased the vehicle in February with about 44,000 miles. This issue has instilled fear in me every time I go to shut my vehicle off never knowing if it will actually shut off or not. Dramatic or not, it has caused unwanted anxiety and too many mental breakdowns that were not needed. This needs to be addressed and fixed ASAP!.

52 Electrical System problem of the 2023 Chevrolet Trailblazer

Failure Date: 03/01/2024

While driving 65-70 mph cruise control will continuously "bog" down and act like it is wanting to cut off the whole vehicle. Transmission is starting to act like it is slipping to the point where I am going all the way to the steering wheel before it catches again. Vehicle is under 36,000 miles and should not be having transmission issues. Radio has been replaced once before but is now doing the same thing where it is not recognizing my phone, directions given to it by touch on screen, and will even completely turn off while in the middle of driving. Will freeze and then act like the screen has 'water' damage. Back up camera is not calibrated correctly. It states that I have more than enough room to make a turn but when looking into my mirrors, it is off by almost a foot and a half. I was in a car accident due to the back up camera malfunction with the difference in distance and with the screen malfunctioning. I have had the vehicle inspected by the chevy dealership multiple times and they have stated that there is nothing coming up on the code reader. The vehicle is available for inspection. My children ride in this vehicle and after the accident, I do not deem it quite safe with the malfunctioning parts. There has not been any lights coming on for the issues but the issues are there.

When you shift to park a message comes up and says shift topark when it is already in park. The main problem is the vehichcle will not shut off. You have to do many differant things to try to get the message to leave and then it will cut off. This has been happening now since it hit 29700 miles and does it almost everytime we drive it now. There is a serious problem here if you cant shut off the vehicle . I also noticed many other people having the same issue with the Trailblazers. This needs a recall fix.

65 Electrical System problem of the 2023 Chevrolet Trailblazer

Failure Date: 05/25/2023

My 2023 Chevrolet Trailblazer is about 3 months old and it’s been making squeaky noises when I break. The squeaky sound is getting worse over time and I have an appointment scheduled with Chevrolet to get this resolved. My concern is a 2022 recall on this same vehicle due to the break system. Therefore, I am reporting this for the year or 2023 because my car is brand new and making screech noises every time I break. Also, my electric system randomly stops working. For example, my touch screen car play system pixelates and sometimes doesn’t even work. I turned off my car and the radio stayed on and the volume wasn’t going down. The car was off and the radio was still playing! after about 15 mins the radio stopped playing while the car was off. Something isn’t right with my Trailblazer, electric and breaks. Lastly, in the images you will see as my millage goes up so does the remaining fuel miles I have left. The fuel miles left are suppose to go down as I’m using the car. Therefore, something is also wrong with my electric dashboard system and fuel meter. Please consider a recall, this is dangerous.

Once on the left shoulder of a four lane hwy(one way), another four lanes on the other side. There was a cement barrier blocking from the other side traffic. I smelled like burnt rubber, now I now it was the brakes. I checked under the hood did not see or smell something burning. After a few minutes the SUV was able to move. I was afraid for my life, just waiting on a vehicle to hit me.

Failure Date: 04/04/2023

I've had the brakes replaced because I thought they were an issue I was having with my abs. But my car will randomly lock its brakes as I'm driving, no matter what speed. I'm scared to drive it. It also almost loses all power after breaking but then speeds up on its own making it almost impossible to slow down or brake.
