Sierra 4WD 8-cyl

  • 39,471 miles
Traveling at a low speed on my property and the truck entered into a "reduced power" mode. Which cut off all power to the drive train. You were left with no ability to go front or back. After shutting off the truck and restarting it returned to normal. Local GMC dealer says he gets one a month for this condition. Costs to repair exceeds a $1000. Lost of power could happen any time. Very dangerous situation.
