What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2000 Mercedes-Benz 400, 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
Engine
Reports naming the engine itself — including stalling, misfires, oil consumption, cooling and internal engine components.
From owner reports, verbatim
VEHICLE SHUTS ITSELF OFF WHILE IN MOTION. PROBLEM PERSISTS AT RANDOM TIMES AND SITUATIONS. INCIDENTS HAPPENED TRAVELING AT 60MPH AFTER 30MIN OF TRAVEL, AT 5MPH AFTER 1 HOUR OF TRAVEL, AND AT 5MPH IN REVERSE SECONDS AFTER TURNING VEHICLE ON. INCIDENTS HAPPENED THE DAY AFTER DEALER DELIVERED NEW VEHICLE. BOTH DEALER AND MANUFACTURER HAVE BEEN INFORMED. DEALER TOWED TRUCK TODAY TO INSPECT. *AK

Fuel system
Reports naming fuel storage or delivery — tanks, pumps, lines, injectors and fuel leaks.
From owner reports, verbatim
ON FILLING THE FUEL TANK WITH GASOLINE, THE GASOLINE SPEWS OUT OF THE FILLER FITTING AS THE TANK FILLS BEYOND 3/4 FULL. THIS OCCURS WHETHER FILLING THE VEHICLE USING THE AUTOMATIC SHUT-OFF FROM THE PUMP OR WHETHER VERY SLOWLY FILLING THE VEHICLE MANUALLY. THIS IS A NEW PHENOMENON INSOFAR AS IT HAS OCCURRED DURING THE LAST THREE FUELINGS OF THE VEHICLE. THIS DID OCCUR ONE TIME ABOUT TWO YEARS AGO. WHEN REPORTED TO THE DEALER, I WAS INFORMED THAT THIS WAS NOT A PROBLEM WITH THE VEHICLE, BUT WITH THE GASOLINE PUMP PUMPING TOO VIGOROUSLY. WHEN I ALMOST LITERALLY DRIBBLED GASOLINE INTO THE PUMP AT THE LAST FILLING, GASOLINE STILL SPEWED OUT OF THE TANK. I ATTEMPTED TO STOPPED THE OUTPOUR (AND I MEAN OUTPOUR) BY PLACING THE GASOLINE CAP ON THE CAR TO CLOSE OFF THE FLOW. AFTER THIS THE CAR MISFIRED WHEN DRIVEN. ALSO, THE GASOLINE GUAGE IN THE VEHICLE ONLY REGISTERED AT 3/4 FULL. IN THE LAST INCIDENT WHICH I JUST DESCRIBED, ONLY A SMALL AMOUNT OF GASOLINE ESCAPED SINCE I WAS "READY FOR IT" THIS TIME, SO IT DOES NOT APPEAR TO BE A PROBLEM WITH THE SPEED OF THE FILLING OF THE TANK, NOR WITH THE VEHICLE HAVING BEEN "OVER-FILLED". I DID NOT REPORT THE LATEST INCIDENT TO THE DEALER SINCE THEY INDICATED THEY WOULD NOT HELP ME WITH THIS MATTER. *AK

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.
