General Motors is recalling just four model-year 2012 versions of the Volt gas-electric hatchback due to a problem with the brakes, according to the National Highway Traffic Safety Administration.
The affected vehicles were manufactured from March 1 through April 17, 2012 (check your vehicle's build date on a sticker on the driver-side doorjamb), and use a faulty brake pressure modulator valve. In these cars, brake pressure from the front brakes during a situation when the antilock brake or traction control systems engage is not relieved. If this happens, the brakes may lock up, increasing the risk of a crash.
GM will notify all affected owners starting Friday, and dealers will install a new brake pressure modulator valve free of charge. Owners can call Chevrolet at 866-694-6546 or NHTSA's vehicle safety hotline at 888-327-4236 for more info.
