Water may enter the windshield wiper motor module resulting in damage over time. The wipers may work intermittently or not at all. Visibility could be reduced, increasing the risk of a crash. Dealers will inspect the wiper module cover and replace it if necessary to correct this concern. The General Motors recall number is 08243.
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.
