2003 Chevrolet Suburban 1500 Problems

ABS Light Due to Poor Electrical Ground Under the Battery Tray

A poor electrical ground under the battery tray may cause the ABS warning light to illuminate. Our technicians tell us that cleaning and properly securing this ground and also the main ABS ground on the frame rail below the drivers door may be necessary.

Intake Manifold Gaskets May Leak Coolant or Engine Oil

The intake manifold gasket may develop an external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Running the engine with a coolant/oil mix may result in engine damage. Replacing the intake manifold gasket should correct this issue.

Power Door Lock Actuators May Fail

The power door lock actuators may become slow to operate or stop working completely and require replacement.

2003 Chevrolet Suburban 1500 Recalls

Rear Seat Belt for Smaller Passengers May Not Fit Correctly

The second row center seat belt routing may make it difficult to position correctly on smaller passengers. If the seat belt rides up to fit around the abdomen, the risk of internal injury is increased in a crash. Dealers will cut the guide loop, remove a portion of the loop, and the remaining sides should be folded over and secured with a retainer. The recall began July 21, 2005. The GM recall number is 05037.

Hydro-Boost Relief Valve May Not Function Properly

The hydro-boost housing relief valve bore may be out of specification. The seal may fracture as a result, which may reduce braking assist and slightly increase the steering effort while braking. Under certain conditions, more braking effort will be required to stop the vehicle. Dealers will replace the hydro-boost relief valve. The recall began June 18, 2004. The GM recall number is 04004.

Vehicle With Installed Southern Comfort Running Boards Recalled Due to Board Lamp Failure

The courtesy lamps on affected running boards may overheat when exposed to moisture and road salt. Overheating may cause the lamps and boards to melt or start a fire. Dealers will replace the wiring harness for these running boards.
