RepairPal Expert Overview

The hydraulic brake booster may fail and leak fluid. The loss of fluid would cause increased steering and braking effort and a crash could occur without warning.


This should be considered a high priority recall. The hydraulic brake booster may fail without warning. Please contact your GM dealer. They will check to see if your specific vehicle is affected and advise you on what to do next. Always have your vehicle identification number (VIN) handy when you call.


On vehicles equipped with the Bosch hydraulic brake booster, the boost pressure accumulator may crack and break away from the hydro-boost assembly during normal operation. If this were to happen while the hood is open, fragments from the accumulator could injure people standing in the immediate area. The loss of fluid while driving would cause increased steering and braking effort and a crash could occur without warning. Dealers will test the hydro-boost assembly for function of the two-function valve. If the hydro-boost assembly fails the test, it will be replaced free of charge. The recall began March 23, 2005. The GM recall number is 05006.
