On certain passenger vehicles, the clip that secures the brake pushrod to the brake pedal arm pin could have been bent when it was installed. A bent clip may come off, allowing the brake booster pushrod to separate from the brake pedal.
Dealers will install a new brake pedal push rod bushing and retaining clip and, if the clip was missing, a new brake pedal arm assembly free of charge. The recall began on April 26, 2005. Owners may contact Buick at 1-866-608-8080.
