When I shift my vehicle into park and hit the button to shut it off, a "shift to park" message appears on the DIC screen. I then am required to start my vehicle again, shift into gear, and then put it back into park and attempt to shut the vehicle off again. It has taken me up to 15 minutes to be able to get it to recognize that my vehicle is in park and for the message to not pop up. If I get out of the car while the message is still on the DIC screen, I cannot lock my vehicle and it drains the battery. I contacted my local Chevrolet dealer and they are saying that although this is a known issue which has had more than one GM Service Bulletin on this issue which includes my year and model, there is not an actual recall for this, so I have to pay out of pocket, because my bumper to bumper warranty expired at 36,000 miles and I am currently just shy of 39,000 miles. Of note, there is also a class action lawsuit for this exact issue so I am confused as to why a recall would not have been issued, or why it would not still be covered despite the expired bumper to bumper warranty.

Onstar module that is supposed to working in case of a crash or another emergency stopped working back in November 2024. It also is attached to other operations such as the vehicles microphone. I took it to the dealership Chevrolet said they would pay half of the replacement. My vehicle is not the only one. There is a forum online and other GM vehicles are having the same issue.

My vehicle displayed a Shift to Park message even though I was already in Park. I could not turn off the engine, I could not lock my car. I had to go back into Drive and then Park mode and wiggle the shifter multiple times to get it to recognize Park and turn off the car. This is now happening almost every time I drive the car. I did an internet search to see how to rectify the problem only to find that this exact issue has plagued GM vehicles for a decade and they still have not chosen to rectify the faulty part. There have been multiple recalls and class action lawsuits for the SHIFT TO PARK fault but not for my vehicle year YET! There are many Trailblazer owners who are experiencing this exact issue (on online forums) and GM so far is refusing to take responsibility and issue a recall to fix the issue for owners and also to stop using this faulty system in their cars. I have reached out to GM about this multiple times the past few weeks and requested they pay for diagnostic and fix the problem because it is a common and known problem with GM vehicles but they want me to pay for it myself and the repair and then they may decide to help out - unacceptable in my opinion. To be honest there needs to be a recall NOW and GM needs to be forced to change the components in all new models to stop this happening in future models going forward. This problem can cause the car battery to drain, it can cause the vehicle to roll away if it’s not recognizing it’s in Park. Thankfully that hasn’t happened to me but others have had this happen. Not being able to shut the engine off or lock my car is a problem. This is a safety issue that needs addressing. I have lots of messages and communication from General Motors which I have attempted to attach the screenshots with the photo below but get an error message on the upload page.

The front exhaust assembly is leaking. There’s many reports online for the same year and vehicle about bolts rusting out. Some still under warranty (36,000 miles, ridiculous!), and some not, like mine. I have 36,800 miles, of course out of warranty. GM has a problem with these exhaust systems, and should be recalled. Thank you

ENGINE
at around 42,000 miles my Trailblazer displayed a message that engine power had been reduced and the check engine light came on. I took it to my dealer who diagnosed as a problem with the engine turbo fixed it and returned the car to me. I drove for 2 weeks and the same thing happened. I traded it in on an Equinox after the service manager said the turbo was a know issued. I did not want to be driving on the interstate with reduced power. Also I took a financial hit on the trade.

The transmission shift control / transmission range sensor / shift interlock solenoid in my Chevrolet Trailblazer is malfunctioning. When I shift the vehicle into park, it fails to recognize the gear change and displays an error message stating, “Shift to Park.” As a result, I'm unable to shut off the engine properly, which poses both a safety risk and a serious inconvenience. I strongly urge the NHTSA to investigate this issue thoroughly and consider issuing a recall to address the defect.

The contact owns a 2021 Chevrolet Trailblazer. The contact stated that while stopped at stop light, the vehicle shut off with the check engine warning light illuminated. Due to the failure, the vehicle was towed to a dealer and the transmission was repaired. Despite the repair, the vehicle continued to shut off without warning. One day while driving 60 MPH, the vehicle shut off without warning, and the contact was stranded in the middle of the highway. The vehicle failed to restart after several attempts even with assistance from the Highway Patrol. Due to the failure, the vehicle was towed to the residence and remained at the residence unrepaired. The manufacturer was not notified of the failure. The failure mileage was unknown.

The bolts attaching my muffler to my exhaust pipe sheared off of my 30,000 mile 2022 chevy trailblazer at highway speed, launching them into my muffler. My exhaust pipe dropped-at 70 miles an hour it could have ripped off, and I am lucky the bolts went into my muffler and not something more vital. Also, If the pipe or muffler had fallen, I-or someone behind me- could have run over it causing potential control issues. I am seeing that this is a common problem on various consumer forums. There was NO warning- didn't even get a check engine light after the fact- things just got REALLY loud. I was fortunate to be close to an exit (as I was in a construction zone) and was able to get a tow to the nearest dealership.

SERVICE BRAKES
I reported my first issue back in late 2024 of the brakes squealing they took my car in and resurface the rotors. It stopped squealing for about a few months and now we are in summer of 2025 and they are squealing again. I took my car to the dealership because they told me that my car would be under warranty for 30,000 miles with the brakes. First started when they told me that the guy that told me I would have a rental car waiting for me did not set me up for a rental car. I live 45 minutes to an hour away from the dealership. When I pulled into the garage, I could hear the squealing of my car. When I went up to the counter the guy told me he couldn’t hear anything. They then tried to tell me that I would have to take my car back home and call back in the morning to talk to the rep I was talking to in the service department as he had already left for the day along with his associate. I was determined that I was not leaving there without a rental car and my car to be looked. I finally went in on my own to find the gentleman who sold me the vehicle who I really do appreciate and have no issues with him(Keith Keys) he’s a very good sales person at Weber Chevrolet. As they were getting me a rental the guy from the service department pulled around with my car and asked me to get in. He then told me that he had fixed the issue by slamming on my brakes a few times and that it was OK for me to take it home. I then let him know that it was staying to be looked at and I was going to take the rental. The next day when I called the service rep, he stated that they were going to replace the front brakes and it would be available the following day to pick up. When I went to go pick up my vehicle and leave the parking lot I didn’t even get out of the parking space and it was still squealing. I went back in and they told me it was normal and I would have to call the service rep the following day I’m still waiting to hear. I have owned many Chevy’s to know breaks don’t do that

SERVICE BRAKES, ELECTRICAL SYSTEM
My 2024 Chevrolet Trailblazer has two main issues. First, there is a constant squealing noise when braking. I reported this twice to the dealer — the first time they said it was just sand inside the wheel. The noise continued. On the second visit, they told me it would cost over $100 to inspect the brakes because the wheel needed to be removed, which I couldn’t afford. This problem started before the vehicle reached 36,000 miles. Second, the electrical system malfunctions occasionally while driving. When I connect my son’s phone to Bluetooth, both the dashboard and infotainment screens shut off completely for a few seconds. This happens while the vehicle is in motion, and it is extremely dangerous, especially on highways. The screens then turn back on. I believe both issues may relate to safety and should be investigated.

I am unsure which component maybe failing, Vehicle has not been in altered in any way ,inspected yet, nor has any warning indicators. This 2021 Chevrolet Trailblazer uses a traditional key for ignition. On several occasions now, the key is becoming lodged/stuck in the ignition when attempting to shut down or turn off the engine and remove the key. Have made sure foot is on the brake, front steering tires are straight, Shifter is properly engaged in the park position, and even jiggled the key tumbler assembly. Have had to leave the stuck key in the ignition while grocery shopping, until returning home to ask my fiance for his help and assistance. When this problem happens it is not only an inconvenience, but leaving a key in the ignition to an unattended car, obviously is not good, and leaves opportunity for many not good possibilites to occur.

AIR BAGS, ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM
Vehicle Diagnostic Summary – Trouble Codes Explained 1. P0562 – System Voltage Low The vehicle’s electrical system is running at low voltage. This could be due to a weak battery, a failing alternator, or poor electrical connections. It may cause various electronic issues and unexpected shutdowns if not fixed. 2. P1005 – Fuel Level Sensor Control Module: Too Many Resets The fuel level sensor module has been reset too many times, likely due to electrical glitches. This may cause the fuel gauge to be inaccurate or unstable. 3. P14C0 / P14CD – Fuel Pump Driver Control Module Signal Error There is a configuration signal error from the fuel pump control module. This could lead to fuel delivery problems, starting issues, or engine stalling if it worsens. 4.
