Vehicle is equipped with a 9 speed automatic transmission that will not engage (even after dealer re-program/re-learn). Transmission must either be manually shifted to 9th gear by paddle shifter or shifted to manual mode and quickly back to auto for it to shift to 9th gear (fuel efficiency affected). Report twice to dealer with no concern for repair. Incident happens at every use of the vehicle (infrequent times it does work (shifts to 9th on its own)).

Transmission fails to automatically shift into 9th gear. A GM bulletin #21-NA-181 indicates this is normal for efficiency operation, but the information indicated is false. Experiencing 9th gear is allowed to be shifted when manually over ridden or when shift to manual mode (without shifting to 9th gear), then shift back to auto mode, then transmission shifts to 9th gear automatically after this is performed then shift to 9th gear automatically during that cycle until vehicle is turned off. So condition GM claims in their "operating condition" is false.

The vehicle's transmission does not shift smoothly in the lower gears (1-3) when decelerating. It feels like a clutch is popping and the vehicle 'jerks' when this occurs.

The vehicle's transmission does not shift smoothly in the lower gears (1-3) when decelerating. It feels like a clutch is popping and the vehicle 'jerks' when this occurs. This began to occur immediately after purchase and continues to do so today. The vehicle was returned twice to the dealer for warranty service and they stated it was operating as designed. The vehicle currently has less than 5,000 miles.
