RepairPal Expert Overview
Our Quick Take:
Increased brake pedal effort may be required due to loss of power braking assist.
What Should You Do?
General Motors will notifying owners of affected vehicles beginning May 30, 2014. If you don't receive notification and believe you should have, please contact your General Motors dealer for further instruction. They may ask for your vehicle identification number (VIN), so please have it handy when you call. The General Motors recall number is 14201.
Power assist to the braking system may be lost due to a problem with the vacuum assist, disabling the hydraulic boost assist. If this were to occur increased brake pedal effort would be required to slow and stop the vehicle, increasing the risk of a crash. Dealers will update the software in the electronic brake control module to correct this concern. Affected vehicles are equipped with a 2.5L engine with the auto stop/start option.

Potential Number of Units Affected:
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."
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.
GM will notify owners, and dealers will update the electronic brake control module software, free of charge. The recall is expected to begin around May 30, 2014. Owners may contact General Motors customer service at 1-800-222-1020. General Motors number for this recall is 14201.
