Vehicle lost engine power on the road. Light display came on stating engine reduce power. It would not pull the trailer. Had to pull over and the display went away only to appear again later. We brought vehicle to chevrolet dealer . The part needed to hopefully fix is on backorder. There is also recall with no available remedy. This is a revenue generating vehicle. We had this problem happen on and off. Dealer didn't want us to bring in until the light physically stayed on dashboard for them to assess vehicle. It was now been in shop for over 2 months
