2003 Chevrolet Suburban 1500 RecallsRear Seat Belt for Smaller Passengers May Not Fit Correctly

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.
