The 2004MERCEDES-BENZE500 carries 172 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 3 crashes, 2 fires, 3 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 2004 E500 is fuel/propulsion system with 55 filings, followed by fuel system, gasoline (26) and suspension (20). 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 2004 E500. 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.

20260120FUEL/PROPULSION SYSTEM

I am submitting this complaint regarding a suspected safety-related defect involving the fuel system of my Mercedes-Benz vehicle. I have experienced a persistent gasoline odor originating from the vehicle. The presence of fuel odor is not a normal operating condition and reasonably indicates a potential failure involving the fuel tank, fuel lines, or related fuel system components. Fuel vapors present a known fire and explosion hazard and constitute a safety risk to vehicle occupants, surrounding vehicles, and property. This condition was not present prior to the issue and has persisted despite inspection. I reported this concern to Mercedes-Benz USA and referenced that fuel odor and fuel tank-related defects have been documented in other Mercedes-Benz vehicles. During my communication with Mercedes-Benz USA, I was informed that an extended or long-term warranty related to the fuel tank or fuel system had existed but was no longer applicable because the coverage period had expired.

20240305FireUNKNOWN OR OTHER

Vehicle started smoking and caught fire while I was driving. Pulled over and vehicle erupted in flames. It took firefighters 2 hours to put out that fire.

20220907FUEL SYSTEM, GASOLINE:DELIVERY:FUEL PUMP

The contact owns a 2004 Mercedes-Benz E500. The contact stated while driving 55 MPH, there was an abnormally strong fuel odor inside the vehicle. The contact stated that upon making a stop, he noticed fuel leaking onto the driver's side rear wheel. The vehicle was taken to an independent mechanic where it was diagnosed that the failure was associated with an unknown recall for the fuel tank. The dealer was notified of the failure and informed the contact that the vehicle was out of warranty. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 71,000.

20220112FUEL/PROPULSION SYSTEM

the car has smelled like gas from the minute i received it. the previous owner told me that mercedes had quoted 5 grand to fix it so i would only put half a tank in at a time. turns out there was a warranty on it but has since expired. why wasn't it fixed for free when the previous owner brought it? this is very dangerous and can cause an explosion. the warranty should have been fixed rather than quoted and seems very greedy to not disclose that information but instead giving a quote. i have lung and heart problems and this is a definite safety issue that needs to be corrected regardless of the age of the car also brought it to dealership scared and they told me too bad it's been too long. how is a gas leak an ok thing to dismiss?????? i have been trying to get this fixed for years and this is my 2nd attempt for a recall with no response at all

20190614POWER TRAIN

THE PROBLEM WITH MY VEHICLE IS THAT WITH ITS CURRENT TCM( TRANSMISSION CONTROL MODULE) IN A 722.9 TRANSMISSION, THE CONDUCTOR PLATE THAT HOLDS THE SENSORS IN PLACE BECOME DEFECTIVE AND CREATES A PROBLEM IN WHICH THE TRANSMISSION GETS STUCK IN 2ND GEAR. THIS CAUSES A MAJOR PROBLEM DRIVING ON ROAD WAYS THAT ARE +45MPH BECAUSE THE VEHICLE CANNOT DRIVE OVER 25MPH FURTHER CAUSING MORE PROBLEMS THAT MAY ACTUALLY FREEZE UP THE ENGINE CAUSING THE CAR TO STOP. IF THE CAR IS STOPPED AND BEGINS TO GO AGAIN, THE RMP'S CAN GO VERY HIGH WITHOUT ANY POWER OR MOTION IN THE VEHICLE. THIS HAS HAPPENED TO 2 OF MY PERSONAL FRIENDS ALREADY WITH THE 722.9 TRANSMISSION. IN PARTICULAR THE CONDUCTOR PLATE OR VALVE BODY WAS CORRUPTED AND CAUSED THE VEHICLE TO FAIL. I AM REPORTING THIS BECAUSE THE PART CAN FAIL ANYTIME DURING OPERATION OF THE VEHICLE AND IS A SAFETY ISSUE TO THE DRIVER AND OTHERS AROUND WHEN THIS MAY OCCUR. MANY OTHER OWNERS (I'VE READ ONLINE) WITH THIS 722.9 TRANSMISSION CONDUCTOR PLATE FAULT

AIRMATIC SUSPENSION DROPPED WHILE DRIVING ON THE HIGHWAY. RED LIGHT WARNING FLASHED THAT VEHICLE WAS LOW. TRIED TO RAISE CAR BUT IT WOULD NOT RAISE. CAR WAS VERY CLOSE TO GROUND AND WOULD NOT RAISE..BEGAN LOOKING UP, IF OTHER SAME MODELS AS OURS HAVE THIS PROBLEM AND THEY DO. READ SEVERAL CONSUMERS COMPLIANTS/ CONCERNS WHO ALSO OWN A MERCEDES BENZ THEY SEEM TO HAVE THIS SIMILAR PROBLEM. IT'S VERY EXPENSIVE TO FIX AT A DEARLERSHIP. LOOKS LIKE THIS VEHICLE MAY HAVE A PROBLEM/DEFECT WITH THEIR AIRMATIC SUSPENSION AND IT IS VERY DANGEROUS DRIVING ON THE HIGHWAY UNKNOWING THAT YOUR VEHICLE IS DROPPING TO GROUND.THIS REALLY NEEDS TO BE INVESTIGATED TO SEE IF THERE IS A PROBLEM WITH THEIR AIRMATIC SUSPENSION BEFORE SOMEONE GETS HURT OR KILLED WHILE DRIVING.
