What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2006 Mercedes-Benz CLS, 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.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

FUEL LEAK AT TOP OF SENDING UNIT UNDERNEATH LEFT REAR SEAT. FUEL SMELL IN CAR. I REMOVED SEAT AND COVER AND DISCOVERED FUEL POOLING. *TR
CLS 55, POST RECALL ON THE FUEL SENDING UNIT. HAVE TAKEN MY CLS INTO THE DEALER FOR OTHER THINGS AND ADVISED THEM THAT I NOTICED A FUEL SMELL IN THE CAR. THEY SAID THEY COULD NOT FIND ANYTHING, SO ON MY WAY I GO. NOW A YEAR LATER, I REALLY NOTICE THE FUEL SMELL WHEN I FILL UP, I PARKED IN THE PARKING GARAGE WHERE I WORK AND WHEN I CAME OUT THERE WAS A PUDDLE OF FUEL UNDER THE CAR ON THE DRIVERS SIDE (CAR WAS PARKED ON A SLOPED GARAGE AT POSSIBLY 20 DEGREE) AND STRONG ODOR OF FUEL IN THE GARAGE. I CALLED MB AND THEY SAID THAT IT'S NOT REALLY THEIR PROBLEM ANYMORE. HMMM, WELL, THE RECALL DIDN'T WORK, DID THEY RE MANUFACTURE THAT PART? *TR
Too few reports in this category for a page of its own — they appear in the full complaint list.
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.
