Odometer: 50,379 Purchased used on April, 1 2024 Odometer: 47,027 Brought to dealer on 8/28/2024 for service. About two weeks ago we had a "Shift to Park" message is displayed on the DIC after the vehicle was placed in Park and shut off. Started it again and then put it in drive then back to park. Message went away. Then over the course of the next week this happened many more times to the point where we were stuck in a shopping parking lot because we could not leave the car as it kept beeping to fix the issue. Made appointment with dealer. After Diagnose from dealer they said it needed to perform Service Bulletin #23-NA-119, recommend replacement of transmission control. They at first wanted us to pay for it and we advised dealer we had a Chevy warranty. After a few days they advised it would be covered under warranty except for our $50 deductible. Main problem is the part # 13545091 was not available locally and dealer had to research to find part. Advise it could take until 9/26/24 to find part. This should be a no charge RECALL by the Mfg. as this can be a safety issue and to ensure more parts are in stock by dealer.

My 2021 Chevy Trailblazer has an error reading “shift to Park” that randomly appeared 2 weeks ago, now is doing it almost every time I stop my car, error has also cause my battery to die. When error is showing my car will not shut off. Took to a Chevy dealer and recommended changing the gear shift assembly, can’t guarantee it will fix the problem. They have ordered the part but $450 plus parts and labor for not a guarantee is concerning. I also travel for work and have been left stranded because of this issue.

The contact owns a 2021 Chevrolet Trailblazer. The contact stated while driving at 5–10 MPH, there was an extremely loud clicking and rattling sound coming from the vehicle. The contact stated that there was an unknown object moving inside the vehicle. There were no warning lights illuminated. The vehicle was taken to the local dealer, where it was diagnosed that the turbo needed to be changed. The vehicle was repaired, but the failure recurred. The dealer informed the contact that the sound was duplicated in other similar vehicles and informed the contact that no further action was needed. The manufacturer was not contacted. The failure mileage was approximately 48,482.

My key gets stuck in the ignition almost every time I turn the car off. In order to get it unstuck I have to restart the car, put the car in drive or reverse, put the car back in park and then try to take the key out again. This has to be repeated sometimes as many as 10 times for it to finally release the key. I have read about many other people having this same problem and eventually the key not coming out at all and they've had to have it cut out. I have an appointment at a dealership for August 1st (the first available appointment) and my vehicle is just out of warranty so I'm told I have to pay to have this fixed. This is clearly a manufacturers defect and first starting happening before my vehicle was out of warranty, I just didn't realize that it would become a much bigger issue the longer it kept happening.

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.

My vehicles check engine light came on at 80,000 miles with a reduced engine power alert. If I'm on the highway I'm unable to accelerate quickly if I needed to. We had the vehicle checked out and it was the Turbocharger that was bad. I had taken it to a Chevrolet dealership and they said other Chevy vehicles have already had a recall on some models for the exact same reason. I believe this is a serious problem with the Trailblazers as well for what I have found online. Please put a recall on this. It's very expensive repair for most people's financial situation.
