What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2001 Mercedes-Benz Clk Class, 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.

Each component in detail
What the reports in each category say, in the owners' own words
Electrical
Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.
From owner reports, verbatim
THE PIXELS ON THE INSTRUMENT CLUSTER WENT OUT AND YOU CAN NO LONGER TELL WHAT GEAR YOU ARE IN. I'VE BROUGHT THE CAR TO MY LOCAL DEALER FOR THEIR INSPECTION AND I WAS QUOTED $1500 FOR THE REPAIR BECAUSE IT IS NOT COVER UNDER WARRANTY. *TR
LEDS ON INSTRUMENT CLUSTER FAULTY. ACCIDENT FREE VEHICLE. *TR

Engine
Reports naming the engine itself — including stalling, misfires, oil consumption, cooling and internal engine components.
From owner reports, verbatim
ENGINE STALLING AND FAILURE TO START DUE TO CRANKSHAFT POSITION SENSOR (CPS) FAILURE. CAR IS A 2001 CLK430 WITH APPROX 60,000 MILES. *TR
MY CAR SHUTS DOWN WHENEVER I DRIVE IN TEMPERATURES OVER 90 DEGREES IN SLOW TRAFFIC. BROUGHT CAR TO DEALER WHO STATED NOTHING WRONG WITH CAR THAT THEY CAN FIND. *NM

Transmission
Reports naming the automatic or manual transmission, including shifting behaviour, shudder, slipping and transmission control modules.
From owner reports, verbatim
THE INSTRUMENT CLUSTER IN MY 2001 MERCEDES-BENZ CLK430 DOES NOT FUNCTION PROPERLY. THE PIXELS IN THE GEAR SELECTOR, TEMPERATURE AND CLOCK SECTION DO NOT LIGHT UP. THIS MAKES IT IMPOSSIBLE TO TELL WHAT GEAR THE CAR IS IN, AND POSES A SAFETY HAZARD. THE "P" AND "R" ARE DIFFICULT TO DISTINGUISH. THIS CAR HAS TRANSMISSION PROBLEMS, AND THE NECESSITY TO IDENTIFY WHICH GEAR THE CAR IS IN BY "FEEL" IS DANGEROUS. *TR
THE AUTOMATIC TRANSMISSION IN MY 2001 MERCEDES-BENZ CLK430 WILL FREQUENTLY BECOME STUCK IN ONLY ONE GEAR. MOST OFTEN 3RD GEAR, BUT SOMETIMES 2ND. THIS IS A TERRIFYING SITUATION FOR ME, ESPECIALLY IN TRAFFIC, AS THE AUTOMOBILE DOES NOT ACCELERATE FROM A STOP IN 3RD GEAR AND ABRUPTLY SLOWS WHEN LETTING OFF THE ACCELERATOR IN 2ND. 2ND GEAR ALSO LIMITS THE SPEED OF THE CAR SIGNIFICANTLY AND HAS CAUSED ME TO BE THE TRAFFIC SLOWDOWN AT RUSH HOUR ON MANY OCCASIONS. I HAVE HAD SEVERAL CLOSE CALLS, AS I CANNOT GET THE CAR OUT OF A BUSY INTERSECTION QUICKLY OR CHANGE LANES TO MAKE A TURN WHEN THIS IS HAPPENING. I DRIVE MY CHILDREN IN THIS CAR AND AM AFRAID THAT A 3RD GEAR START OR A 2ND GEAR ABRUPT SLOWDOWN OR ITS SEVERELY LIMITED VELOCITY WILL CAUSE AN ACCIDENT AND THEY MAY GET HURT. THE ONLY WAY TO REMEDY THIS SITUATION IS TO PULL OVER, SHUT OFF THE CAR AND RESTART IT. THIS IS NOT ALWAYS POSSIBLE ON A BUSY STREET, AND IS DANGEROUS AT BEST. MY MECHANIC HAS DETERMINED THAT THIS IS NOT A MECHANICAL FAILURE IN THE TRANSMISSION, BUT A FAILURE IN THE ELECTRONIC MODULE THAT CONTROLS THE TRANSMISSION. I UNDERSTAND THROUGH CORROBORATIVE AND ANECDOTAL EVIDENCE THAT THIS COULD BE A RESULT OF LIQUID FROM THE CUPHOLDER SEEPING DOWN INTO THE ELECTRONICS. THERE IS EVIDENCE OF A LIQUID SPILL, AND IT IS CLEAR THAT THE POOR DESIGN OF THE CUPHOLDER AND ITS LOCATION ABOVE THE TRANSMISSION ELECTRONICS ARE THE CAUSE OF THIS SAFETY ISSUE. WE HAVE NOT PURSUED REPAIR AS OF YET, AS THE PARTS AND LABOR ARE QUITE EXPENSIVE. THE CAR IS NOW PARKED IN MY GARAGE, AS I CONSIDER IT UNSAFE TO DRIVE. *TR

Body & structure
Reports naming the vehicle structure, frame, body panels, doors, hood and trim.
From owner reports, verbatim
IN MOST PARKING LOTS, LOW CONCRETE "CURBS" ARE PLACED IN STALLS TO PREVENT CARS FROM PULLING TOO FAR FORWARD. TYPICAL CURBS ARE ABOUT SIX INCHES IN HEIGHT. WHEN PARKING IN MANY LOTS IT IS NECESSARY TO PULL A CAR FORWARD SO THE FRONT TIRES TOUCH (OR NEARLY TOUCH) THESE CURBS. OTHERWISE, THE BACK END OF THE CAR WILL BE TOO FAR OUT IN THE FLOW OF TRAFFIC. THE FRONT BUMPER OF THE 2001 MERCEDES CLK 430 IS PRONE TOWARD DAMAGE ON THESE CURBS WHEN BACKING OUT OF A PARKING STALL. THIS OCCURS BECAUSE OF A LIP ON THE LOWER PORTION OF THE FRONT BUMPER THAT CATCHES ON THE CURB. WHEN THE CAR IS BACKED OUT, THE LOWER FRONT BUMPER CATCHES ON THE CURB AND WILL CAUSE THE BUMPER TO BREAK. THIS SITUATION IS NOT ISOLATED TO MY OWN CAR. OVER THE PAST YEAR I HAVE EXAMINED THE BUMPERS OF MANY CARS OF THE SAME MODEL AND YEAR (IN VARIOUS PARKING LOTS). WITHOUT EXCEPTION, EVERY BUMPER HAS BEEN BROKEN IN A SIMILAR MANNER. THIS BUMPER WAS DESIGNED SO THAT BREAKAGE IS UNAVOIDABLE, EVEN UNDER NORMAL USE. THIS SEEMS TO BE A MANUFACTURER'S DEFECT THAT WOULD JUSTIFY A RECALL.*JB

Fuel system
Reports naming fuel storage or delivery — tanks, pumps, lines, injectors and fuel leaks.
From owner reports, verbatim
FUEL GAUGE NOT READING CORRECT FUEL. AFTER FILLING TANK, FUEL GAUGE READS EMPTY. AFTER APPROX 20 MILES OF DRIVING FUEL GAUGE MOVES TO FULL. FUEL GAUGE THEN CONTINUES TO READ INACCURATE MEASUREMENTS. I AM USING THE MILEAGE TO KNOW WHEN TO REFUEL. *TR

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.
