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.

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.

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.

2003 Chevrolet Suburban 1500 Reviews

My truck has been very dependable and versatile, whether taking my family of six on a 2000 mile road trip or hauling loads of sheetrock and yard debris. Trim seems to hold together, except the color coating on my dashboard is peeling off -- revealing its true color, black. Paint has stayed true. Suspension handles well on and off road. It's a nice tough truck.

2003 Suburban...A great vehicle. Only problem in 82,000 miles has been a rear window regulator. Milage has been good, pulls my boat with ease. This is my second Suburban and I'd buy another.

I have had my suburan for 5 years and i have nothing bad to say about it the only trouble i have had is out of the tramission at 80,000 miles other than that brakes,oil changes, and we bought a battery, great truck and i bought it at 62,000 miles it has 140,000 on it now we are getting a new one
