2023 Chevrolet Trailblazer Problems

This incident is in regards to a fire that occurred in the engine bay area, post having turbo replacement and spark plug replacement done by a local dealership where this car was purchased new. Car had roughly approximately 60,000 miles and had a check engine light and engine reduce power notification on dash. Was taken to the aforementioned dealership for general scope of work while in the possession and actively being test driven for the repair the vehicle was driven 5 miles and the driver was flagged down by motorists for smoke. The incident was recorded by Riverside Police Department and Riverside fire department. The origin and caused are still undetermined at this time. Some background in history of this vehicle has never been in a crash and has not had any parts replaced from the original purchase.

While driving to work last Thursday morning suddenly my 2023 Trailblazer let out a sorta growl and then a dragging noise thankfully I was able to get over and stop on the shoulder only to discover that my tail pipe was dragging from just after the catalytic converter as the bolts apparently sheared off leaving only the head of the bolts intact. Lucky for me I there wasn’t major damage. I did however have to get my vehicle towed and have the bolt heads cut off in order to have the exhaust fixed

The contact owns a 2023 Chevrolet Trailblazer. The contact stated that while his wife was driving at an undisclosed speed, the brake pedal felt extremely firm and was difficult to depress. The contact stated that his wife needed to anticipate the stopping distance to apply enough force to the brake pedal while stopping the vehicle. The vehicle was taken to the dealer on several occasions, but the technicians continuously stated that there was no failure with the vehicle. The vehicle was taken to an independent mechanic and was diagnosed with an inoperable brake master cylinder. The contact was informed that the brake master cylinder needed to be replaced. The vehicle was taken back to the dealer with the information; however, the dealer stated that the brake master cylinder replacement was not necessary. The vehicle remained unrepaired. The manufacturer was notified of the failure. The failure mileage was 40,000.

When shifting to park, car alerts to “shift to park”

Shift to Park error message when car is already in park and then difficulty getting car to turn off. This is an ongoing issue. I have seen online this is a common problem. This is a safety issue because if the car doesn't turn off the battery will go dead leaving a driver stranded. This issue began soon after the car was out of warranty.

When shifting to park, car alerts to “shift to park”

The shift assembly is going bad and causing a Shift to Park error that GM is aware of. They have issued a Technical Service Bulletin about this exact part. The error code will cause the battery to run down leaving me stranded. The dealer has inspected the vehichle and ordered the necessary part to replace it. The vehicle has not been inspected by the manufacturer, police, insurance representatives or others but is available to have an inspection done. There were no warning lamps for this other than the Shift to Park error showing on the display when the car has been turned off. These error messages started happening around August 1, 2026.

The contact owns a 2023 CHEVROLET Trailblazer. The contact stated that while parking the vehicle, the computer system failed to recognize that the vehicle had been shifted into the park position, causing a "Shift to Park" warning light to illuminate on the instrument cluster. Although the gear selector was physically in park, the contact was unable to fully shut down the vehicle and had to cycle the ignition on and off multiple times until the system eventually recognized the park position. The vehicle was driven to the dealer where it was diagnosed to be a transmission control assembly failure. The vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was 61,097.

My family and I was I involved in a hit and run accident. My minor child is still suffering from shoulder/rotator cuff injuries. Hewas in the process to start conditioning for football. The seatbelt on the day of the accident did not lock. GM sent a criminal investigator not a trained engineer for the vehicle. The seatbelts needs to be inspected. The motor/transmission is making a ticking sound.

I was in a collision. Traveling a four lane highway during daylight ours with no in-climate weather. The car in front of a line of approximately 4 cars missed their exit and slammed on his breaks to make a right turn from the driving lane. The line of cars in front of me stopped and/or left the roadway to avoid a collision. I was unable to stop in time and had nowhere to go and I rear-ended the car in front of me, which was fully stopped in the lane. According to my dash camera my speed on Impact was approximately 45 mph. No front end collision warning alarms went off. No automatic breaking occurred. No airbag deployed. None of the vehicle safety and anti collision measures performed as I had expected. $10,000 worth of damage to my car alone.

While driving on the highway in light traffic at approximately 70 mph and changing lanes, the side airbags in my vehicle suddenly deployed without warning. There was no collision, no contact with another vehicle, no road debris, and no apparent external cause for deployment. I did not strike anything before, during, or after the deployment. There were no vehicles within several car lengths of my vehicle at the time. Highway Patrol was dispatched to the scene. Officer TJ Carter with Guilford County responded. Upon inspection of the vehicle at the scene, we found no evidence of impact or contact with another vehicle, object, or debris. The vehicle was covered in yellow pollen at the time, and even light contact would have left visible marks or disturbance in the pollen. After examining the vehicle, no signs of contact were identified. The vehicle does have unrelated prior body damage from over a year ago on one side, but that damage predates this incident and was not caused by this event. The responding officer can confirm there was no collision or new impact associated with the airbag deployment. There was no accident associated with this airbag deployment. The airbags deployed while I was traveling at highway speed, which caused a sudden and dangerous driving event and required me to quickly maneuver to the side of the roadway. This created a serious safety risk to me and to surrounding traffic. Prior to this incident, there were no warning lights, safety alerts, or service notifications indicating an issue with the airbag system or vehicle safety systems. However, a notification did appear in the My Chevrolet app at or around the time of the incident. The vehicle has not yet been fully inspected following the incident. A safety claim has been submitted to General Motors. I also have video footage of the Highway Patrol Officer cutting down the airbags on-site but cannot add that below so I have added a screenshot.

The ABS system in this vehicle flashes warnings at quick restarts and while holding the brake down, it has no “sponge” when this happens. The brakes squeal constantly. I’ve had them inspected at every single maintenance and there can be no flaw found. When driving on the interstate, the engine is very “jerky” almost like the transmission can’t keep up with the speed of 70-80mph (not always, but it is noticeable when it happens). At first I didn’t think much of it but with the mass recall of chevys identified, I believe it needs to go on record - particularly about the brakes.

The contact owns a 2023 Chevrolet Trailblazer. The contact stated that while driving at undisclosed speeds, the vehicle independently activated the brakes while the accelerator pedal was depressed. In addition, the contact stated that while attempting to make a left turn, the steering wheel independently veered towards the right. The check engine warning light was illuminated. The vehicle was towed to a local dealer where it was diagnosed, and the brake master cylinder assembly was replaced. The vehicle was repaired; however, the failure reoccurred. The vehicle was taken back to the same local dealer and was left for further investigation. The manufacturer was not made aware of the failure. The failure mileage was approximately 25,000.

Steering warning light comes on while driving and steering locks up. Dealer inspected the vehicle and states the steering unit did pull a code, however is not serviceable and will need replaced. I do not feel safe driving the vehicle as the steering locks up and cause a serious accident. The dealer advised it may take several weeks for the parts to arrive. I am reading other reports of Trailblazer owners facing the same service issue. I am requesting a rental car from GM and/or the dealer until my car is fixed, however they told me I have to pay out of pocket myself. I am disgusted this brand new car is facing such a serious safety issue. This needs investigated ASAP before someone is killed on the highway.

The sunroof shattered/exploded while driving. Sounded like an explosion. Nothing hit it. Shards of glass fell inside before I was able to close the material part.
