This vehicle has been in and out of the shop several times for the same reason, "reduced engine power". It puts me in a dangerous position sometimes because the vehicle will suddenly go into this "limp mode" I have spent several thousand dollars in repairs and fixes by qualified mechanics and yet this problem will not go away. After much research I find that I among many people with the same problem. It happened three times yesterday!.

I was driving on the 55 freeway, and all of a sudden my electrical gps, radio, and power turned off for approx. 5 sec. And the dash rebooted, and radio remained off, and the car was still crusing, but losing speed. I put the car in neutral and had to restart while cruising. It is not the first time this has happened. Spoke to GMC parts dept. On the phone, and he stated there is no recall for this vehicle. This has happened approx. 5 times. I shared that information to the parts dept. And he stated that they could do a diagnostic that would cost a pretty hi amount to check, and if nothing come out of it I asked. Then he stated nothing.
This is the 2nd occurrence of the same incident in 3 months. While moving slowly through a parking lot, the engine just stops. No shudder, no rough idle, no warning. Without power, steering is impaired or impossible. Turning the ignition key restarts the engine normally. Jiggling the key cannot replicate the problem.
The reduced power light comes on and the engine loses power.
Whining in engine-found to be metal in differential.
