My AWD went out on 3 occasions, each time I was told they found nothing. One day I lost acceleration power and then the engine light came on. The dealership said my pistons were not firing and had to be replaced with the turbo. All was covered, however two weeks later my red oil alarm came on, I was out of oil. The car went back to dealer, all oil was burned up and so was my turbo. I had taken my car in previously for large amount of smoke coming out the back-end. I was told nothing was found to be wrong?

While traveling at higher speeds (60+ mph), the check engine light will come on and the car will lose significant power in 4th and higher gear. This will present as speed can still be gained although very slowly in 4th gear, speed can be maintained but not gained while in 5th gear, and speed will only be lost while in 6th gear. 3rd gear and below all work fine. This issue is resolved by turning the car off for a while and then it continues to operate as it should thereafter, however, the check engine light will remain lit for a few days. The main concern is that the car loses the capability to get out of the way in the case of an emergency due to the lack of power while in this state.

Our vehicle started losing pick up and go in the middle of driving about 2 weeks ago. Check engine light came on, so we took the vehicle to identify the issue. Error codes P0299 turbo/super charger underboost issue was identified. We called the dealership and were told the part is on backorder until maybe July. Even after market parts apparently are unavailable because GM is purchasing them. We contacted service manager at dealership because we are without a car that we are paying for and there is a huge concern that if the part is this difficult to obtain, there must be an undisclosed issue going on here. The service manager said they are only able to obtain updates for parts once the part is ordered, but also did confirm there is ( not necessarily a backorder, but the part is hard to come by!?!). he could not answer why. He did encourage us to contact Consumer Affairs to escalate our concerns. We did contact Consumer Affairs and were directed to contact NHTSA. We currently are without our vehicle that we continue to pay for and continue on this journey of tell this person or department and we are getting nowhere fast. Something bigger is obviously going on here and as always the paying customer continues to be the one paying for it. We want the part and it would be nice to not be inconvenienced with scrambling everyday on how to get to/from work and how to get to/ from caring for elderly parents who are in need of our assistance to eat, bath and remain safe. This issue is a huge inconvenience and truth needs to be told by GM/Buick.
