While driving to work one morning an error message flashed engine reduced power, stability control loss. Truck struggled to accelerate. Has happened several times since November 2015 on city streets or highways can happen at any time. I had to replace entire system from throttle body to the pedal assembly have found out that this is common problem that GM knows about along with the cracks in the dash around air bag on passenger side and the instrument cluster and refuses to recall and fix cracks in air bag housing could pose a safety hazard along with loss of engine power from faulty wiring.

The stability track control came on and I took it back to a GMC dealer to have it checked. I had extended warranty and they covered it. The problem was they took 9 days to find out what was wrong. I was out 9 days without my vehicle.the light continues to come back on and now I have to take it back. It occurs when I am on the street moving.
