The 2000MERCEDES-BENZ400 carries 2 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 0 crashes, 0 fires, 0 injuries, and 0 fatalities. No NCAP 5-star crash-test rating is available for this model year in the federal database.
Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2000 400 is engine and engine cooling:engine:gasoline with 1 filings, followed by fuel system, gasoline:storage:tank assembly:filler pipe and cap (1). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability.
NHTSA currently has 15 investigation files overlapping the 2000 400. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

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
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
