Driving along then the truck just shakes, check engine light comes on. Then dash says service stabilitrack and then says reduced engine power. Truck goes only 10 miles an hour and almost stalls . It’s so much fun when ur on a highway and this happens and you almost get killed by those riding your tail. This seems to be a major issue I have been reading up on. GMC is going to have some issues with customers who bought this death trap.
