Recall - ABS Module Reprogramming
Subject:
F/CMVSS Noncompliance-Rear Brakes May Not Fully Release-Reprogram ABS Computer Module
# 07177 - (09/21/2007)
Models:
2007 Chevrolet Express
2007 GMC Savana
Condition
General Motors has decided that certain 2007 Chevrolet Express and GMC Savana vehicles fail to conform to Federal/Canada Motor Vehicle Safety
Standard 108, requiring the illumination of the stop lamps whenever the brakes are applied. When the brakes are applied on these vehicles, the stop
lamps will illuminate. When the brake pedal is released, the stop lamps are no longer illuminated but the rear brakes may still be applied. The brake may
release after a few seconds or after the next firm brake pedal application. If the rear brakes are still applied after release of the brake pedal, the driver
may notice a substantial drag when driving and may need to depress the gas pedal further than usual to continue vehicle movement. A vehicle driven with
the brakes applied can cause overheating of the brakes, resulting in increased stopping distance, which could result in a vehicle crash.
Correction
Dealers are to reprogram the anti-lock brake system (ABS) module.
