Recalls, owner-reported complaints, investigations and safety data

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

Latest Dec 19, 2003
InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.

I HAVE BLACK MERCEDES C230 KOMPRESSOR SPORTS SEDAN 2004 MODEL. CAR WAS PURCHASED BRAND NEW AT MERCEDES AUTHORIZED DEALER. THERE IS NO MODIFICATION MADE TO THIS CAR AND ALL THE SERVICING DONE AT MERCEDES AUTHORIZED DEALER SINCE I BOUGHT THIS CAR. IT HAD ONLY 58000 MILES. LAST B SERVICING WHICH CHECKED ANY SAFETY RELATED ISSUES AND INCLUDES REGULAR MAINTENANCE, WAS DONE AT AUTHORIZED DEALER ON 02/18/2012. NO ISSUE WAS INFORMED ON 02/18/2012 TO US BY MERCEDES AUTHORIZED DEALER SERVICING DEPARTMENT. ON 06/21/2012, WHEN I WAS DRIVING THIS CAR FROM WORK TO HOME, I TURNED ON A/C, A/C SHUTDOWN AND I STARTED SMELLING SMOKE. ON LEFT SIDE OF MY CAR THERE IS A/C VENT AND I SAW FIRE INSIDE THE HOOD THROUGH THAT VENT.I PULLED OVER CAR RIGHT AWAY AND ELECTRICITY WENT OUT WITH IN 1 MIN OF MY PULLING OVER AND WITHIN 4 MIN, WHOLE CAR WAS BURNING. MY CAR IS NOW TOTALED. THIS POSES FOLLOWING SECURITY CONCERNS: 1. MERCEDES C230 2004 IS MADE OF HIGHLY INFLAMMABLE MATERIAL AND DRIVER AND USERS OF CAR HAS VERY LESS CHANCE TO SURVIVE IF THERE IS FIRE. 2. MERCEDES C230 2004 MODEL A/C UNIT IS NOT OF HIGHEST QUALITY AND ELECTRICAL SYSTEM IS FAULTY. BOTH OF ABOVE ISSUES POSES VERY SERIOUS SECURITY RISKS TO PUBLIC AND IT NEEDS THROUGH INVESTIGATION. I CONTACTED MERCEDES HEAD QUARTER FOR INVESTIGATION AND MERCEDES DECLINED TO INVESTIGATE. GEICO STATED IN REPORT THAT HOOD IS STUCK AND CAUSE OF FIRE IS UNKNOWN. GEICO INSURANCE COMPANY AUTHORIZED MERCEDES ENGINEERS TO INVESTIGATE FURTHER UPON MY REQUEST AND MERCEDES USA DOES NOT WANT TO INVESTIGATE FURTHER. I HAVE PICTURES OF BURNT CAR AND CAN SHARE IF IT HELPS IN INVESTIGATION TO RULE OUT ABOVE 2 CONCERNS. WE DO NOT WANT OTHERS TO GO THROUGH SAME ORDEAL AS WE WENT THROUGH. *TR UPDATED 06/13/13*LJ UPDATED 06/17/2013 *JS

I WAS TRAVELING ON THE FREEWAY (APPROXIMATE SPEED 60 MPH) WHEN I HEARD SOMETHING HIT THE WINDSHIELD OF MY 2004 MERCEDES C240. THERE WAS NO IMMEDIATE SIGNS OF DAMAGE. HOWEVER, ABOUT 30 MINUTES LATER AFTER I HAD MADE STOP AND LATER RETURNED TO THE CAR I NOTICED A 12 INCH CRACK IN THE WINDSHIELD. I BELIEVE THERE IS A SERIOUS DESIGN DEFECT WITH THE WINDSHIELDS IN MERCEDES. A CO-WORKER OF MINE HAS HAD TO REPLACE THE WINDSHIELD IN HER 2004 C320 MERCEDES TWICE WITHIN THE PAST 18 MONTHS. THE SERVICE REPS HAVE TOLD HER THAT THIS HAPPENS ON THE TIME, ESPECIALLY FOR COMMUTERS WHO TRAVEL THE 91 FREEWAY HERE IN SOUTHERN CALIFORNIA. I WOULD THINK THAT R&D WOULD HAVE DONE SUFFICIENT TESTING TO ENSURE THAT A WINDSHIELD COULD WITHSTAND CONTACT WITH A ROCK OR PEBBLE.
