FUEL/PROPULSION SYSTEM05/26/2026
Approximately in March 2026, I started noticing a very strong gasoline odor coming from my 2004 Mercedes-Benz E 500 4-matic with original miles approximately 56,300. The fuel odor always got stronger whenever I would fill up the gas tank. The history on my car is such that it has always been garage kept. The gasoline odor coming from my car started getting stronger and stronger while in my garage. On Memorial Day 2026 I called HQ, Mercedes Benz and told them about the gas odor coming from my car. After the call ended I decided that the car needed to be towed to the nearest Mercedes Benz service center. I considered that the gas order to be very dangerous so I parked my car in the driveway. Once parked in my driveway, there was no longer a gasoline order in my garage. Now even while parked in my driveway, I could smell gasoline around the rear of my car when I opened the doors the gasoline smell was very strong. All of this happens suddenly and only grew worse within the last four days. The gasoline smell was probably there for a long time but I didn’t notice it since I do not drive the car very often. That should be obvious because there is only approximately 56,300 miles on the car and those are original miles. I called Mercedes-Benz headquarters and requested a tow to the nearest Mercedes-Benz repair shop which is in Tampa Florida. As my car was being placed on the flatbed tow truck gasoline started spilling out onto the bed of the tow truck. That is a very dangerous situation. My car could’ve caught fire if it hit something hard or if I had been in an accident. I read where there is a 15 year extended warranty from year the analysis was actually completed in 2012 by the ODI NHTSA. I believe my car falls under the purview of the extended warranty. I’m reporting this problem because it is very dangerous and there could be other vehicles out there.
FUEL/PROPULSION SYSTEM01/20/2026
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. I was not made aware of this extended warranty at the time it was active and therefore had no opportunity to seek inspection or repair while coverage was in effect. Mercedes-Benz USA has acknowledged my complaint but has declined to provide corrective action beyond internal review. Given the safety implications of fuel system defects and the potential impact of inadequate disclosure of extended safety-related warranty coverage, I am requesting that NHTSA document this complaint and evaluate whether this condition represents a broader defect trend and whether recall or further investigation is warranted. This complaint is submitted to ensure the issue is formally recorded as a potential fuel system safety defect.

To Whom It May Concern, I took my 2004 Mercedes-Benz into the Stevens Creek location located in San Jose, CA 95129 to have the sliding roof bonding recall fixed on December 24, 2024. I have attached the repair invoice to this complaint. It has now been almost two full months and I am still being blocked from updating my vehicle registration because my vehicle needs to complete an Official Brake and Light Adjustment Certification. However, the recall vin lookup page (https://vinrcl.safercar.gov/vin/) has been showing my recall as incomplete for almost two full months now. The mechanic that performs the Brake and Light inspection says the vehicle will fail the test until the recall vin lookup page displays a 0 for my vehicle. Once again, this issue is preventing me from updating my vehicle registration until the recall vin lookup page shows the successful completion of the vehicle recall performed on December 24, 2024 at Mercedes-Benz of Stevens Creek. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The sunroof has a recall due to the fact that it has a bad seal, which could fly off due to this issue. I know the seal is bad because the whole roof leaked a few years ago and fried all the electronic; e.g. lights, sunroof controls, trunk light controls, side door controls. I went to the dealership and they said they would not fix it because they could not open the sunroof to see the manufacturer date on it.
VISIBILITY/WIPER04/22/2024
The driver's side mirror auto-dim function failed (as theorized by simple research where others have this issue) December 2023 and leaked a liquid behind the glass causing blurriness, double vision, and extremely dim reflection. This makes it difficult to safely judge other traffic using the mirror and seems very dangerous while driving. It also seems to present a risk of misjudging any other objects on the road which are reliant on this mirror. The equivalent replacement mirror glass alone is prohibitively expensive and Mercedes-Benz USA was contacted twice for help and refused to provide help or replacement. Neither the manufacturer nor another entity has inspected it yet. The mirror is available for inspection upon request. The passenger side view mirror is not auto-dimming so there is no issue.

The glue around front windshield has deteriorated and has caused major damage to my interior lights, electrical essemblys , interior damage to seats , dash board and flooring. Including the trunk seal is also deteriorated and causing the battery to stop working and has made my car non drivable.
EXTERIOR LIGHTING12/27/2023
Mercedes Benz has a KNOWN safety problem with this model and has not put it under recall yet and it needs to be. The wire casing in the wiring harness for the headlights crumbles and leaves exposed wires that touch, short, and draw causing dim headlights. Due to being cited for dim headlights the night before, I called MBUSA on December 27 2023 and they initially REFUSED to take a case from me.

The TRUNK will not open. It is supposed to open by pressing the button on the key fob or taking the thin key out of the key fob and manually open the truck with the keyed lock. Neither method works. There is absolutely no way to open the trunk otherwise (i.e. inside button or lever). When the key fob button and the thin key do not work there is absolutely no way to open the truck. There is no way to access the lock from the trunk lid rear and there is no way to access the trunk from behind the back seat cushions. It is a very bad situation and dangerous.
