GENERAL MOTORS CORP.
What Happened
Your vehicle's anti-lock brake system (ABS) relies on a small spring clip that keeps the motor in place. Unfortunately, some of these clips are not meeting the manufacturer's specifications, which could cause the motor to become misaligned.
Risk if Unfixed
If the ABS motor becomes misaligned, it could eventually stop working, which means the system that helps balance your front and rear brakes (Dynamic Rear Proportioning) would fail — but your regular brakes would still work, albeit less effectively.
Free Fix
Your dealership will replace the faulty brake pressure module valve assembly at no cost to you.

Original — What Happened
VEHICLE DESCRIPTION: LIGHT DUTY PICKUP TRUCKS EQUIPPED WITH 4-WHEEL DISC BRAKES. SOME OF THESE VEHICLES HAVE AN ANTILOCK BRAKE SYSTEM (ABS) MOTOR CONTAINING AN OUT-OF-SPECIFICATION SPRING CLIP. THIS CLIP COULD ALLOW THE MOTOR BEARING TO BECOME MISALIGNED. IF MISALIGNMENT OCCURS, EVENTUALLY THE ABS WOULD BE NON-FUNCTIONAL.
Original — Risk if Unfixed
THE BASE BRAKES WOULD REMAIN FULLY FUNCTIONAL, BUT THE DYNAMIC REAR PROPORTIONING (DRP) SYSTEM, WHICH OPTIMIZES FRONT TO REAR BRAKE BALANCE, WOULD BECOME INOPERATIVE.
Original — Remedy
DEALERS WILL REPLACE THE BRAKE PRESSURE MODULE VALVE ASSEMBLY.
