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.
0
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.
0
Crash or fire reportedComplaints whose submitter recorded that a crash or a fire occurred. These are the reporter's own answers on the NHTSA form, not verified findings.

WHILE DRIVING WITH A/C SET ON "AUTO" THE A/C SYSTEM WOULD SUDDENLY TURN OFF BY ITSELF AND WOULD TURN OF REPEATEDLY WHEN STARTED AGAIN. DURING SUCH EPISODES THE A/C WOULD ACT ERRATIC WITH FANS TURNING ON AND OFF AT DIFFERENT OUTLETS, CYCLES BETWEEN HEATING AND COOLING, AND MAKES HISSING SOUNDS. THIS WOULD OCCUR MANY TIMES A DAY ON A DAILY BASIS IN SUMMER WEATHER (EXCEPT WHEN THE CAR IS TAKEN TO THE DEALER, IT SEEMS). IT TOOK ABOUT 2 YEARS FOR THE DEALER TO FINALLY FIX THE PROBLEM SINCE THEY COULD NOT AVOID ADMITTING ITS EXISTENCE AFTER I HAD VIDEO TAPED THE MALFUNCTION AND SHOWED THEM THE VIDEO.. *JB

I OWN A 2003 MERCEDES C240 STATION WAGON WITH ABOUT 42000 MILES, A FEW DAYS AGO I OBSERVED SOME MESSAGES ON DASH WHICH SEEM TO INDICATE ALTERNATOR PROBLEM. MY VEHICLE HAS NOT BEEN HEAVILY USED AND I AM SURPRISED TO LEARN THAT A NEW ALTERNATOR MAY BE NEEDED, THIS BECAUSE A FRIEND WITH C CLASS SEDAN HAS HAD THE SAME ISSUE JUST 2 WEEKS AGO AND COST HIM $1500 TO REPLACE THE ALTERNATOR & BATTERY. I BELIEVE THERE MAY BE MANY MORE FOLKS THAT EXPERIENCED THE SAME SITUATION AND PROBABLY THE C CLASS MERCEDES ARE OUTFITTED WITH FAULTY ALTERNATORS AND INVESTIGATION MAY BE IN ORDER HERE. *JB

MY MERCEDES-BENZ C-240 (2003 MODEL), HAVING LESS THAN 18500 MILES, SUDDENLY LOST POWER AFTER SOME 2-HOUR WORTH OF FREE-WAY DRIVING. AROUND NOON ON FRIDAY, 8/26/05, I WAS DRIVING SOUTH -BOUND ON I-15 PAST VICTORVILLE (CA), ABOUT 9 MILES PAST THE EXIT FOR ROUTE 18, WHEN MY C-240 SUDDENLY LOST POWER. AS I DEPRESSED THE ACCELERATOR, I FELT NO POWER AND THE RPM WAS DECREASING. IT FELT LIKE THE ENTIRE ENGINE-TRANSMISSION SYSTEM WAS SHUTTING DOWN. THERE WAS NO PRIOR WARNING. I MADE RIGHT TURN SIGNAL LETTING OTHER VEHICLES KNOW I WAS COMING OFF THE FREE-WAY. I MANAGED TO PULL OFF TO THE RIGHT SHOULDER SAFELY AND CAME TO FULL STOP ON THE GRAVEL. AT THAT TIME, MY DIGITAL ODOMETER READ "1 MALFUNCTION". USING MY CELL PHONE, I IMMEDIATELY CALLED THE MERCEDES HOTLINE. THE ROADSIDE ASSISTANCE REPRESENTATIVE, KRISTIN, ADVISED ME NOT TO DRIVE THE VEHICLE, EVEN AFTER THE "1 MALFUNCTION" SIGN BECAME "NO MALFUNCTION" A LITTLE LATER. MY VEHICLE WAS TOWED TO A MERCEDES-BENZ DEALER IN RIVERSIDE, SOME 50 MILES AWAY. AT THE DEALERS SERVICE DEPT, AFTER A BASIC CHECK INVOLVING COMPUTER AND ELECTRONICS, SOME FAULTY IDENTIFICATIONS WERE MADE, BUT IT WAS DETERMINED TO BE SAFE AND DRIVABLE. I DROVE MY VEHICLE HOME, PLANNING TO HAVE A MAJOR CHECK UP LATER. *JB

They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.

Complaint and recall counts across every year of this model
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers. Older model years have had longer for reports to accumulate.
