2007 GMC Sierra 1500 Problems

Suspension & Steering -- Verified

The steering may develop a clunk type noise from the upper intermediate steering shaft.  Our technicians tell us that you should check with you local GM dealer to find out what the latest repair is for this condition.

Electrical & Lights -- Verified

The daytime running lights are prone to burning out. Our technicians tell us that the light sockets may show signs of heat damage but usually are OK. Always be sure to use the correct replacement bulb for the best life expectancy. The new bulb recommendation for 1999-2003 models is #4114K (trade number).

Electrical & Lights -- Verified

The speedometer or other instrument panel gauge may begin to work erratically at times. Our technicians tell us that the instrument cluster must be sent to a repair facility to correct this fault. The warranty has been extended on some of these units to 7 years or 70,000 miles.

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.

Exhaust & Emissions -- Verified

The muffler heat shield may become loose on the muffler causing a rattle or popping noise. Our technicians tell us there is a kit available from GM to correct this problem.
