Everything below is an owner-reported complaint submitted to NHTSA about the 2007 Mercedes-Benz CLK550, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.

PARKED MY CAR IN MY GARAGE FOR THE NIGHT, NEXT MORNING MY GARAGE HAD A STRONG SMELL OF GAS. WHEN I GOT IN THE CAR IT WAS EVEN STRONGER. HAS BEEN 3 DAYS NOW AND YOU CAN EVEN SMELL THE GAS OUTSIDE OF THE CAR WHEN IT'S BEEN PARKED.THE OVERWHELMING SMELL OF GASOLINE INSIDE CABIN OF MY CAR IS NAUSEATING AND I'M AFRAID IT'S GONNA CAUSE ME TO LOSE CONSCIOUSNESS.
THE VEHICLE STALLED, ENGINE QUIT, ON A BUSY SIDE STREET. THE DRIVER PULLED OVER ON THE DIRT SIDE OF THE STREET. RESTARTS WERE ATTEMPTED TO NO AVAIL. THE ENGINE WILL IDLE FOR A COUPLE OF SECONDS THEN SHUTDOWN. IT SOUNDED LIKE FUEL STARVATION. THE FUEL INDICATOR SHOWED 4 BARS OR A LITTLE UNDER HALF TANK. THE FUEL TANK WAS FILLED WITH 5 GALLONS OF GASOLINE WHERE THE VEHICLE STARTED FINE AND DRIVEN HOME. THE CAUSE WAS FOUND OUT TO BE A FAULTY FUEL INDICATOR. IT LATER FREEZES ON HALF FULL EVEN IF IT IS FILLED TO FULL TANK AT THE GAS STATION. FUEL GAUGE READINGS ARE INCORRECT AND INTERMITTENT. RESEARCH FROM NADA GUIDES ON THIS VEHICLE REVEALED US NHTSA CAMPAIGN ID 08V303000 AND MERCEDES BENZ RECALL NO. 2008 07000, REGARDING INCORRECT SOFTWARE CALIBRATION NUMBER CODING. HOWEVER, THIS VEHICLE'S VIN DOES NOT SHOW ANY RECALL OR SERVICE BULLETIN. UPDATED 09/25/15*LJ.......UPDATED 10/19/15 *BF UPDATED 12/21/2015 *JS UPDATED 01/25/16.*JB
