Consumer Description

Driving at normal speed when my 2021 Yukon backfired and began to lose power. The check engine light came on. The vehicle would go into reverse and would not get over 20 miles an hour. It has been at a GM repair shop since March 24th waiting on the tranmission valve body. There is no ETA from General Motors on when this part will be available. Could this be associated with the most recent GMC recall of 2021-2024 Cadillac, Chevrolet and GMC vehicles?
