2024 Chevrolet Tahoe Power Train

The contact owns a 2024 Chevrolet Tahoe. The contact stated that on four occasions while in reverse (R), the "Service Transmission" message was displayed, and the vehicle failed to reverse. The contact was able to shift into drive(D). The vehicle was taken to a dealer on four separate occasions, where it was diagnosed and determined that the transmission shifter had failed and needed to be replaced. The vehicle was repaired all four times, but the failure reoccurred. The manufacturer was not notified of the failure. The failure mileage was approximately 4,293.

My wife drove the 2024 Tahoe with 13,464 miles to Florida for a beach trip with the kids. The car stopped working while she was driving. The vehicle flashed and the automatic transmission wasn’t changing gears. She manually shifted the gears until arriving at a safe place. The dealer states it is the transmission valve body that needs replaced. The part is on back order and from what the dealer said being built as needed.

Brand new 2024 Z71 Tahoe at 11,000 miles had transmission failure due to the transmission valve body failing. No previous issues, has never driven long distance, has never towed anything. While in school drop off line was alerted and given an error message on screen stating “reduced acceleration, drive with caution” placing the vehicle in limp mode and check engine light came on.
