What owners report
The contact owns a 2026 Chevrolet Trailblazer. The contact stated that while driving between 45 and 60 MPH, the air bag and safety restraint warning lights unexpectedly illuminated. After the warning lights illuminated, the steering felt loose, and the brake pedal locked, slid, and then released when engaged. The contact also stated that an electrical failure occurred. The vehicle was taken to the dealer; however, the failure was not diagnosed or repaired. The vehicle was scheduled to be diagnosed by the dealer for a second time. The contact noted that the vehicle had previously been repaired for a separate electrical failure. The failure mileage was approximately 20,000.
I experienced a Hard Stall at a Red Light. The Auto Start/Stop Feature was engaged. The Console displayed "Press Brake Pedal to Start". I had to shift into Neutral and manually restart the Vehicle. I had the Vehicle checked at my Dealer and there were No Error Codes Thrown and the Dealer Service Department could not recreate the Stall.
The contact owns a 2025 Chevrolet Trailblazer. The contact received notification of NHTSA Campaign Number: 26V539000 (Back Over Prevention); however, the part to do the recall repair was unavailable. The contact stated the manufacturer had exceeded a reasonable amount of time for the recall repair. The contact stated that while in reverse, the back over prevention camera displayed a black screen. The failure was causing the screen to flash and failed to display pertinent information. The failure caused the battery to become drained. The dealer was contacted and confirmed parts were unavailable for the recall repair, and any repair would be at the owners expense. The manufacturer was made aware of the failure. The failure mileage was 36,800.
The vehicle has experienced ongoing and unresolved issues despite multiple service visits. The primary concern is excessive engine vibration. It shakes concerningly when backed into a driveway at an incline and placed in park. This occurs while the vehicle is stationary and idling. The issue has been reproduced and acknowledged by a dealership service advisor during a test drive, who stated the vibration was excessive and concerning. However, no repair was completed, and no clear diagnosis has been provided. The vehicle has also displayed repeated error messages with no confirmed cause, ongoing Bluetooth connectivity issues even after system updates and resets, and a malfunctioning forward collision warning system. Prior repair attempts include replacement of the backup camera, center console, and exterior windshield trim. …
My daughter was stopped at a stoplight and the auto-stop engaged. The light turned green and she began to accelerate when all of the error lights on the dash lit up, then the dash info system and infotainment system went out followed by the engine turning off and not restarting. While all of this happened, the vehicle behind me struck my daughter's car. Luckily it was at a low rate of speed and no one was injured. I took the car to the dealer and after nearly a week of testing they found nothing wrong and found no error codes in the system. They ere not able to replicate the problem. However, once we got the vehicle back a similar instance happed again, except just the dash info system and infotainment system went out and the car was still drivable. Once restarted the electronics came back on as normal. It has not happened again at this point. …
I was driving my 1 week old vehicle, on a city street, foot still on the gas, and the vehicle COMPLETELY shut down; no power at all. it wasn't the auto start/stop technology, but rather a complete power down. no lights, no hazard lights, no dash, nothing worked. The car came to an abrupt stop. The gear shift could not be moved into neutral, nothing. Luckily I was on a city street with not a lot of traffic. If I had been on a highway it could have caused a SERIOUS accident; if I had been driving across railroad tracks and it stops - very dangerous. I was able to contact AAA, and after a "jump", it started. However, because of my proximity to the highway, I opted to have it towed to the dealer where I bought it....they ran service on it and can find nothing wrong with it...as you can imagine, I am nervous to drive on the highway (which I do 5 days a week normally)...
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. …
