NHTSA recall 99V238000
Service Brakes, Hydraulic · General Motors, LLC
Details
What's wrong: The brake booster to pedal assembly attachment nuts may be loose.
Why it matters: If these nuts are loose, the brake pedal may be low, the assembly may be loose, the brakes may not release, and if the nuts back completely off, braking may be lost. Also fume and water intrusion to the passenger compartment can occur.
The fix: Dealers will replace any missing brake booster to brake pedal assembly nuts and tighten all four (4) nuts to specified torque.
