| Engine And Engine Cooling problems |
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 service attempts and remain unresolved. The engine vibration and malfunctioning safety systems raise safety and reliability concerns, including the potential for reduced driver awareness and increased risk of a collision.
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!.
While driving the car stalled and eventually stopped running. The battery was still on, but there was no power to the engine. The car needed to be pushed out of the road and towed to the dealership for work.
