What owners report
The contact owned a 2021 Chevrolet Trailblazer. The contact stated that while driving, the vehicle suddenly shut off. The message "Reduce Engine Power" was displayed before the instrument panel went blank. The manufacturer was notified of the failure. The vehicle was towed to several mechanics and the dealer, and the vehicle was diagnosed with timing chain failure. The contact was informed that the engine needed to be replaced. The failure mileage was 48,000.
I have been having issues shifting into park. My Trailblazer will sit there and tell me to shift into park multiple times before it will recognize park. Iâve had to hit the gear shift a couple times before it will recognize park.
While driving on the interstate on October 17, 2026, my 2021 Chevrolet Trailblazer (1.2L turbo) suddenly lost engine power and would not accelerate, with the check engine light on. I had to coast to the shoulder and have the vehicle towed. The dealer diagnosed a failed turbocharger and a failed timing belt at 110,904 miles â far below GM's own 150,000-mile replacement interval for this belt. A timing belt that fails early can cause sudden, total loss of power at highway speed with no warning. This is a serious safety hazard. An Ohio state trooper had to assist with getting myself and my minor son off the interstate and to a safe location.
My 2021 Trailblazer does not shift into drive properly from park or reverse. When shifting into drive, the engine revs but does not move forward. In some cases, the vehicle also shakes and jolts for several seconds. It is also slow to shift into higher gears at high speeds on the freeway. In cases of quick acceleration, the check engine light comes on and the message "Engine Power Reduced" shows. This has caused potentially dangerous situations where I am not able to accelerate to match the flow of traffic, especially when merging onto the freeway. I have taken the car to both a Chevy dealership and an independent shop, who have both confirmed that there is a "loss of forward gear" and pul
ABS brake system failed causing breaking to surge and not work correctly and not stop like it should resulting in having to have the ABS module and pump replaced at an extreme cost. With no clear cause and using the same parts this is likely to happen again. Had to be taken to the dealer because it required special software and bleeding procedure that a local shop wasn't able to do. The dealership stated that this should probably be covered soon in a recall that this was a known problem and they have had quite a few issues with this ABS pump assembly.
