I have seen several posts on this condition occurring, where the Engine Power is reduced, and the stabilitrack and traction control go off, and the message is to service both. I have NOT seen a consistent solution to this problem. There have been some that said electrical, the battery, something with the AWD, etc. I have had a local dealer tell me that it is the Throttle Body. This is a serious issue, needing a resolution. Imagine being on the highway, you lose engine power, and a tractor-trailer and other are barreling on behind you. How do you get out of the way? Once pulled over, and letting the car sit for a short while, the car will start and run fine. This is an intermittent problem, that comes unpredictably. Is there an answer? Is it the Throttle Body? I have this cleaned twice, once by the dealer and once by a local mechanic. This is short-term fix evidently. I need something permanent. Someone please advise, and share your success in getting this resolved.
