Read complaints for GMC C4500 (2007)
Truck lost almost all power and barley moved itself from the travel lanes to the side of the road, had to be towed and after a week in the shop! at my business loss .a crank sensor was determined to be faulty,then an e.g.r valve and finally replaced the p.c.m. Check engine light still on and off and still weak on power. Fuel usage is horrible most of the time 6 -7 mpg. Truck currently towed to another dealer for a transmission problem, it wont move!! i found trans to be almost out of fluid. I check fluids regularly. Truck has 16k on it now. And this is the second tow, the first at 2,000 miles.
Vehicle has complete fuel system failure.in talking to dsu in portland, they told me that this is a common problem in this year of vehicle and that a check valve in the fuel pump disintegrates and destroys the entire fuel system.they told me that gm knows about this issue, has changed the check valve in newer injection pumps but will not warranty and or recall these pumps.this causes a $12,000 repair.
