2010 GMC Sierra 1500 Problems

Electrical & Lights -- Verified

It is common for the fuel level sensor in the fuel tank read the fuel level incorrectly. The sensor must be replaced to correct the condition. Our technicians recommend having the complete fuel pump module replaced on high mileage vehicles.

Exhaust & Emissions -- Verified

One or both secondary air injection check valves may become restricted causing poor air flow resulting in illumination of the Check Engine Light. It is often recommend to replace both check valves even if a fault code is set for only one bank of cylinders. Replacing only one valve may result in a return trip to the repair shop.

Heating & Air Conditioning -- Verified

Extended life coolant may become contaminated and require cooling system service before the recommended 100,000 miles.

Engine -- Verified

Engine -- Verified

The fuel pump may fail causing the engine to stall and not restart.

Bought this new off the showroom floor. 15 months later, I love it as much as the day I purchased it. Plenty of power, great looks, and decent mileage for a truck.
