A useful visit to this page takes five minutes. YearTell does not score years and cannot see the vehicle in front of you.

  1. Look up the VIN for open recalls at nhtsa.gov. This year has 2 campaigns on file below.
  2. Fuel system. Check for fuel smell, leaks and whether it starts and idles cleanly.
  3. Brakes. Have a shop check pads, rotors, fluid and whether the pedal feels firm.
  4. Engine. Have a shop check for oil consumption, coolant leaks, rough idle and unusual engine noise.
  5. Skim a few owner reports below for Fuel system. Look for the same symptom repeating.
  6. Take that list to a mechanic. Do not turn the complaint total into a score.

The contact received notification of NHTSA Campaign Number: 19V918000 (Visibility); however, the contact was informed by the dealer that the sunroof glass was manufactured in a year outside of the year stated in the recall. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue and informed the contact that the sunroof glass was not covered under the recall. The contact had not experienced a failure.

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)

SBC braking system stated as covered under 25 year/unlimited miles warranty. SBC system failed on 2/1/25. Vehicle towed to local dealer service facility on 2/3/25. Tow was authorized at no charge by MB Roadside Assistance at no charge plus $100.00 credit toward diagnostic. Was told by phone on 2/3/25 that upon confirmation that SBC did in fact fail, the SBC replacement would be performed at no charge due to warranty through 2028. As of 2/10/25 service facility did confirm that the SBC system had failed. Currently, MB USA has a HOLD pending for authorization of repairs, with no reason given as to why as of 2/13/25.

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.

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.

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.
