I-??m just adding confirmation to my solenoid/waste gate/ turbo system reduced engine power on the 2021 trailblazer around 23,000 miles. [XXX], Raleigh n.c INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Turbo failure resulted in loss of engine power. I was driving down the road and the engine light came on and I got a notification that the engine was in reduced power mode. The vehicle became very sluggish and lost speed. While I was fortunate that I was not on a busy road, had the incident happened on the highway it could have been dangerous given my loss of speed. What's of greater concern, this appears to be a common problem on the Trailblazer message boards. The dealer confirmed it was the turbo and stated that the part was on back order. This indicates the problem is occurring very frequently. The vehicle only has 33k miles on it.

The Turbo is bad in the car at 90,000 miles. It is a common issue among these, lots of other people have the same issue with the -??engine power is reduced-?? message popping up, per the 2021 Chevrolet TrailBlazer facebook group. There needs to be a recall so they can be fixed. It has happened on mine for the past few months and the dealer said the turbo is bad. The purge pump has already been replaced.

When I shift the gear from PARK to DRIVE & step on the GAS, the vehicle hesitates to DRIVE. I have to turn off my vehicle, play with the gear shift, then shift again to get it to move. The other day I put my vehicle in DRIVE and it rolled back and REVERSED. Nobody can figure out what-??s wrong with my vehicle. The check engine light comes on then goes off. Nobody can get the problem to duplicate. A ticket to GMC was submitted and from them, my vehicle seems fine on paper. This is a safety hazard. I-??ve taken my vehicle to a Chevy dealer and also to a GMC dealer multiple times.

The vehicle began to give the error Shift to Park when the vehicle was in park and after the power was shut off. Because of this I cannot safely turn off the vehicle because it cannot recognize it's in park and will run the battery down whenever I use the vehicle. This problem has been previously presented in other models manufactured by GM. I am taking the vehicle in for inspection at a local Chevrolet dealership on 9/24/22 at 8 am. This issue first started around the second week of September this year with one or two errors here and there. Now, it happens every time I drive the vehicle.
