NHTSA Campaign Number: 13V335000
Component(s): EXTERIOR LIGHTING
Potential Number of Units Affected: 6,308
Vehicle Model Year(s) Make Model: 2012-2013 FORD FOCUS
Manufacturer: Ford Motor Company
Ford is recalling certain model year 2012-2013 Focus BEV vehicles equipped with High Intensity Discharge (HID) headlights, manufactured September 15, 2011, through May 6, 2013; and model year 2013 Focus ST vehicles equipped with High Intensity Discharge (HID) headlights, manufactured February 16, 2012, through May 7, 2013. Due to a wiring incompatability, the front side marker lamps may not function. Thus, these vehicles fail to comply to the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 108, "Lamps, Reflective Devices, and Associated Equipment."
Without the proper illumination of the side maker lamps, the vehicle may be less visible in night time conditions, increasing the risk of a crash.
Ford will notify owners, and dealers will modify the headlamp assembly wiring, free of charge. The recall is expected to begin in mid-August 2013. Owners may contact the Ford customer relationship center at 1-866-436-7332. Ford's recall number is 13C04.
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
