This page combines three types of NHTSA data: recall campaigns (official manufacturer or government actions), owner complaints (unverified consumer reports), and crash test ratings (where available). A vehicle with many complaints is not necessarily less reliable — complaint volume correlates with sales volume and vehicle age. Recalls indicate identified defects, not overall quality. To compare this model year with others, use the year navigation in the sidebar or return to the model overview page.
The secondary instrument fuse block located on the driver's side of the dashboard erupted in flame while the vehicle was being driven, endangering its occupant, causing significant damage to its interior, and resulting in a local law enforcement "traffic hazard" determination.
The contact owns a 2003 Mercedes-Benz C320. The contact stated that the sunroof had failed to open, and the sunshade cover failed to close, causing the sunrays to penetrate the vehicle. The vehicle was taken to the dealer, where an unknown assessment was made. The vehicle was not repaired. Additionally, the contact stated that the horn was inoperable. The SRS warning light was illuminated. The vehicle was taken to an independent mechanic, where it was diagnosed with front driver's side air bag failure. The vehicle was not repaired. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 124,000.
The PRINX tires and the dealer - Mavis Tires, Auburn Avenue, Columbus, Georgia, are equally to blame for the flat I had in traffic endangering myself and other motorists with Brand New Prinx Tires, and also the skid I had at an intersection in Columbus Georgia. It's the old story of Chinese aftermarket parts that do not fit causing accidents. Prinx pushes Mavis to make sales of their 205/55/16 even though my Mercedes C240 door panel sticker shows the brands Mercedes lists for safety as in climates averaging 39 degrees and above for traction size 225/50/16 has to be placed in the rear (205 only on the front) and I did by buying more tires I didn't need and that stopped the skidding. MAVIS also installed the Prinx tires pretending to have replaced the dry-rotted stems, I had a flat at an intersection endangering other drivers, my wheel was also damaged. I have replaced the other stems and the rear tires which did not fit and had poor traction, but MAVIS will not exchange with me for a proper fit. I think Mavis should be fined as they are endangering motorists by not replacing dry-rotted stems to pinch pennies and deliberately placing tires on the rear despite the door sticker warning for size and fit and brand. The Prinx tires are also low on the ground like a go-cart, making the car harder to maneuver. The Better Business Bureau has so many complaints against Mavis Tire, home office New York, that I didn't bother.

AT 178,000 MILES THE TIMING CHAIN TENSIONER FAILED WHILE THE CAR DRIVING APPROXIMATELY 25 MPH AND ALLOWED THE TIMING CHAIN TO SKIP SEVERAL TEETH LEAVING THE CAR STRANDED AND POTENTIALLY CAUSING THOUSANDS OF DOLLARS WORTH OF DAMAGE TO THE ENGINE INTERNALS. THE CAR WAS DEALER SERVICED SINCE NEW AND ALWAYS HAD MAINTENANCE ON TIME. THERE IS THOUSANDS OF PEOPLE ONLINE THAT HAVE HAD THE EXACT SAME ISSUE AND MERCEDES BENZ USA REFUSES TO DO ANYTHING ABOUT IT YET THEY ACKNOWLEDGE THEY MADE THEM WRONG BECAUSE THEY HAVE UPDATED THE CHAINS AND TENSIONERS.
THE BACK SIDE OF THE TIRES CRACK OPEN AROUND THE RIM.
HARMONIC BALANCER /CRANK PULLEY WOBBLING VERY BAD . AFRAID IT WILL COME APART AND CAUSE CATASTROPHIC DAMAGE WHILE MY KIDS ARE DRIVING. MERCEDES COVERED THIS PART UNDER SAME ENGINE FAMILY BUT ONLY FROM MODEL YEARS 1998-2001. WOULD LIKE THEM TO TAKE RESPONSIBILITY FOR THE SAME FAULTY PART AS THE OTHERS.
I WAS DRIVING MY CAR AND IT SUDDENLY TURNED OFF ON ME. I TRIED TO START IT AGAIN BUT IT WOULD CRANK BUT NOT TURN ON. I HAD A LIL LESS THAN HALF A TANK OF GAS BUT THERE WAS NO GAS BEING DELIVERED TO THE ENGINE. AFTER INSPECTING THE FUEL SENDING UNIT I NOTISED THAT THE PLASTIC AROUND THE WIRE CONNECTOR PINS WAS A BIT MELTED AND THERE WAS A SMALL HOLE THAT WENT STRAIGHT TROUGH THE SENDING UNIT COVER. I REPLACED THE SENDING UNIT BUT THE MELTING STILL CONTINUES. IT SEEMS LIKE THE WIRE GETS TOO HOT AND THE PLASTIC MELTS AROUND THE PINS. IM AFRAID THIS CAN EVEN CAUSE A FIRE SINCE ALL THE FUEL IS JUST INCHES BELLOW IT.
TAKATA RECALL SRS WARNING LIGHT ON
MERCEDES BENZ POSSIBLE RECALL / EXTENDED WARRANTY FOR FUEL SYSTEM... INVOLVING A C CLASS 2003 WITH SAME ENGINE AS THE E CLASS. THE CAR FUEL SYSTEM IS TOTALLY MESSED UP, WILL ONLY FILL A HALF TANK AND RUNS OUT OF GAS BECAUSE THE FUEL TANK SYSTEM IS NOT WORKING CORRECTLY. CAR WILL NOT FILL. ONLY ONE TANK TAKING AND SENDING FUEL APPARENTLY. DASH IS MESSED UP, LIGHTS OUT, FUEL SYSTEM TOTALLY MESSED UP. I ALMOST WENT OFF A CLIFF IN THE CAR, SLID BACKWARDS ON A HILLSIDE WHEN THE CAR RAN OUT OF FUEL UNEXPECTEDLY. NO GAS, NO POWER, MY CAR WENT BACKWARDS, BRAKES NOT WORKING, I WENT INTO A DITCH AND ALMOST INTO A STEEP HILLSIDE, VERY SCARY. A CAR BRANCH SAVED MY DEMISE, HOLDING THE TOP OF THE CAR AND KEPT ME FROM GOING DOWN INTO A RAVENE. DENT ON THE BACK ROOF IS STILL THERE. MERCEDES BENZ REFUSES TO ACKNOWLEDGE ANY PROBLEMS ALTHOUGH THE PROBLEM IS APPARENTLY PROLIFIC IN CARS THIS YEAR AND TYPE. SAME FUEL SYSTEM ON A C320 AS AN E320 SAME YEAR. SAME ENGINE TOO. MY MECHANICS ARE BAFFLED, NO ONE CAN FIX IT, MERCEDES SHOPS DON'T WANT TO HELP, NO ONE CAN HELP.
AFTER FILLING MY GAS TANK, THERE'S A VERY STRONG RAW GAS ODOR INSIDE THE CAR WHILE DRIVING, AND WHEN PARKED. SEEMS STRONGER IN THE BACKSEAT. I SEE THERE'S A EXTENDED WARRANTY FOR THIS ISSUE FROM MERCEDES BENZ ON THE E CLASS FOR MY YEAR (2003). THAT WARRANTY EXTENSION SHOULD HAVE COVERED ALL CLASSES WITH SIMILAR DESIGN OR THE SAME PROBLEM. THE FUMES ARE SO STRONG I AM AFRAID ANY SPARK COULD IGNITE THE VAPORS. I REALLY NEED YOUR HELP! IF MERCEDES BENZ ACKNOWLEDGED PROBLEMS WITH MY YEAR (2003), IT SHOULD INCLUDE MY C CLASS UNLESS THEY CAN ESTABLISH THE ISSUES ARE TOTALLY UNRELATED IN NATURE. THANK YOU FOR YOUR ASSISTANCE.
