Electrical system

14 reports
“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.”

Power train

6 reports
“Component Affected: POWER TRAIN: AUTOMATIC TRANSMISSION / TRANSMISSION CONTROL MODULEDescription of Safety Defect:The vehicle is experiencing a severe, intermittent, and violent mechanical "garage shift" engagement lurch. This occurs specifically when shifting the gear selector from Reverse to Drive during a cold-start cycle.When the gear is selected, there is a distinct hydraulic delay followed by a violent mechanical slam that causes the entire vehicle to violently lurch forward. This unintended vehicle movement occurs even though the engine has naturally idled down completely below 1,000 RPM, and while the brake pedal is fully and firmly depressed to the floor.Safety Hazard and Consequences:This defect poses an immediate and severe safety hazard. The mechanical force of the lurch is strong enough to potentially overcome the vehicle's braking system or cause a foot-slip off the pedal, resulting in sudden, unintended vehicle movement. This creates a high risk of a low-speed collision, vehicle damage, or striking a pedestrian or property during tight parking or garage maneuvers. General Motors' internal service bulletins (such as Bulletin 24-NA-009) indicate…”

Engine

“My vehicle started overheating out of no where towed it to the shop, it’s been there for 2 weeks they’re actively waiting for a manufacturer engineer to tell them what to do because they can’t figure out how to fix it. On top of that there have been a lot of overheating issues cause by different parts on the vehicle. There was another trailblazer in the at the same time as mine that was also overheating! A 2025 vehicle should not be having issues at this point gmc should just take all the trailblazers off the market! Also they need to change their manufacturing warranty on rentals because not one person should not have to pay out of pocket for a rental when it’s the manufacturers fault!”

Forward collision avoidance

2 reports
“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. The windshield trim repair was incomplete, as only the middle section was replaced while the remaining components were not, resulting in a mismatched and unresolved condition. No service documentation was provided for the most recent visit despite being advised that updated findings would be sent. These issues have persisted across multiple…”
