Vehicle has 120,000 miles on it and has a random misfire, with traction control and stabiltrack warnings and a flashing check engine light. Engine has excessive oil consumption and runs rough. Installed new plugs and wires, no change. After reading up on these engines I found out that the afm / dod feature is a common failure for these engines. Gm should step up and help owners with some of the repair costs. This is going to be expensive.

Traveling at a normal rate and speed on a 5-lane highway. Vehicle loss power, engine lights activated. After maneuvering the vehicle off the highway, I shut the engine off. No signs of smoke or any leaks from engine (topside or underneath). I attempted to restart the vehicle and upon doing so the engine turned over and ran at a rough idle, clearly not on all 8 cylinders. I shut the engine off again. From that point on it was towed. The chevrolet dealership (after 8 days and 449 miles later) then told me they could not find a problem. When they received the vehicle the original codes had been taken by a precision tune mechanic (nearest facility from location of break down) the dealership then informed me they could not duplicate the problem and was apologetic for any inconvenience. I received a bill for $103.95 and my vehicle which had only a 1/8 of a tank of fuel. After a little research I found gm recall no:08048 consequence: may cause electrical features to malfunction. Thanks chevrolet and chevrolet service technicians for taking care of your customers. Unfortunately their dealerships and district specialist do not follow their own executive director of safety who is quoted on the gm website "we always want to make sure customers can count on the safety and quality of their gm vehicle." says, [xxx].
