While driving down busy road, for no reason engine power was suddenly reduced which could have resulted in a serious accident. This has happened numerous times. Called gm. No recalls. This appears to be an inherent problem, not wear and tear. This needs to be addressed asap. *tr

On multiple occasions the vehicle has lost power at highway speed and the engine dies. After a few attempts the engine restarts and operates normally for an unpredictable interval. This has happened at least 10 times. The authorized dealer and other mechanic shops have not been able to diagnose the reason for the power failure as they have not been able to cause it to duplicate failure when they have it. This sudden…

I was traveling at approximately 55mph on a smooth paved county road with my a/c on. It was about 78 degrees outside. I had the a/c running about 15 minutes before the air just turned warm. I tried 3 times turning off the a/c and back on, and the air failed to cool. I stopped the truck, turned the a/c on, got out and looked at the a/c compressor. The a/c compressor was not engaging. I took it to a mechanic and the…

Inspection revealed that the heads on several exhaust manifold bolts had broken off. Reportedly, this has been a very common defect in gm p/u trucks and suv's. From what some technicians have said, gm used substandard bolts for this application, and that they simply cannot bear up under the heat from manifolds. Many complaints have been filed by vehicle owners, but gm refuses to acknowledge the problem and institute…

I purchased this vehicle used on march 1 2013 didn't noticed any problems except a slight engine noise. I thought the engine noise was tapping valves, because i was told the truck was not on the road for about a year. When i changed the oil for the first time i noticed that the rear manifold bolt was missing, looked at the other side, that was missing also. I heard i could e-mail you to report a problem so i did.

Before this started happening it stayed at a steady 14 volts. Now the voltage is dropping and the rpm's are dropping to around 200-300 rpms then some times it will die in motion. I have replaced the alternator and had the battery tested they are good.…
