GENERAL MOTORS recall on S10SIERRA,SILVERADO, and SONOMA models

Certain vehicles may have an Antilock Braking System (ABS) motor containing an out of specification spring clip which could in time become misaligned. This could cause retainer bearing friction, higher motor current draw and eventually render the ABS non-functional. This would cause the warning lights to illuminate and the Dynamic Rear Proportional (DRP) system to become inoperative. The base brakes would still remain functional and if the operator were to ignore the red brake warning light, the higher rear brake input could cause rear wheel lock up with the possibility of a crash. Correction: Dealers will replace the back pressure module valve assembly.
