Vehicle Message ‘Reduced Acceleration Drive with Care’ . My car then ran like it was in 1st gear for my drive home. Next morning couldn’t go into reverse so I had to have my buddy help me tow it. Went to the dealer and they said that it’s ‘an ongoing issue with GM that they haven’t addressed with several vehicles and the part (Valve Body) is on backorder with no ETA. With this horrible safety issue you would think GM would just take the hit and change out the entire transmission instead of making people wait so long without their vehicles.
