NHTSA campaign 14V247000
Hazard
General Motors LLC (GM) is recalling certain model year 2014 Chevrolet Malibu vehicles manufactured June 12, 2013, through May 2, 2014, and equipped with a 2.5L engine with the auto stop/start option. The affected vehicles may experience a complete loss of brake vacuum assist, disabling the hydraulic boost assist. As such, these vehicles do not comply with Federal Motor Vehicle Safety Standard (FMVSS) number 135, "Light Vehicle Brake Systems."
Consequence
If the hydraulic boost assist is disabled, slowing or stopping the vehicle will require additional brake pedal effort and a lengthened stopping distance. Both of these effects increase the risk of a crash.
Remedy
GM will notify owners, and dealers will update the electronic brake control module software, free of charge. The recall began on July 3, 2014. Owners may contact General Motors customer service at 1-800-222-1020. General Motors number for this recall is 14201.
