As I was driving down the road at 55 mph hour my SUV began to shake extremely and was throttling at very high rpm's and the SUV thrash to sudden halt and continued to shake and idle very high and loud. I tried to hit the gas to get myself off the road as I was on a 2 lane highway with my 4 year old son in the car, and the engine revved and the rpm's spiked but I went not more than 15 mph, at the same time the following errors appeared on my screen: 1) service stabaili trak 2) engine power is reduced slowly I was able to safely get the car up to 35 mph and get us home safe. I did some research and seems that this is a very well known issue with GMC so I contacted GMC and was basically given the runaround. I took the car to a GMC dear today and was told it was the fuel pump that needed replaced. . . . .
