Vehicles Affected: Approximately 9,100 model-year 2015 Mercedes-Benz C300 and C400 luxury cars manufactured between June 18 and Sept. 5, 2014
The Problem: The vehicles were assembled with horizontal adjustment mechanisms for headlamps that allow the owner to change the horizontal adjustment used during the manufacturing process, instead of the proper sealing caps. If the original horizontal adjustment is used to alter the low beam aim, the misaimed headlamp may not properly illuminate the road or may cause increased glare to oncoming drivers, increasing the risk of a crash.
The Fix: Dealers will replace the horizontal adjustment mechanisms on the headlamps with sealing caps.
What Owners Should Do: Mercedes-Benz began notifying owners on May 23. Owners can call the automaker at 800-367-6372, the National Highway Traffic Safety Administration’s vehicle-safety hotline at 888-327-4236 or go to www.safercar.gov for more info.
