The engine and transmission shakes and they say all this normal. Vibration occurs throughout vehicle at idle or driving at any speed. Also, rpm hand slightly moves up and down while idling in park. The vibration is more prominent in 2 and 3 row seats. I have taken it in about 7 or 8 times for the same issue to 4 different dealerships. Only one has actually felt the issue and visually saw the vibration/hop in rear of vehicle. The technician could not determine the problem as GM only allowed a visual inspection. He was not allowed to take anything apart so I am still left with the issue and it is getting worse. In addition, vehicle taken to collision shop to inspect frame, vehicle was within spec. Vehicle is now back at another dealership to address the issue. The only thing that all the dealerships have done is road force balance tires, alignment, and changed out driveshaft axle from a prior recall. I paid to have to have a differential fluid change still has vibration. At this point, it is concerning because as I stated the problem is getting worse. Also, dealers are looking for a computerized answer and I dont think a powertrain issue will be diagnosed this way. My truck should be under recalls but none has applied to it.
