In owners' words
Complaint narratives as filed with NHTSA, trimmed for length.
-
When I filled up gas and start the car, it has gas smell. seems like fuel is pooling on the left side on top of the fule filter module underneath the cushion. Searched the internet and found out it is a common problem on Mercedes.
-
The seal that connects the fuel level sensor to the fuel tank has failed, allowing fuel to leak onto the top of the tank when it’s filled. This creates a serious risk of fire or explosion. Unfortunately, Mercedes does not offer a remedy unless you pay a prohibitively high fee.
How to read this page
Every figure comes from the National Highway Traffic Safety Administration's public complaint database, which holds every safety-related defect complaint filed by owners since 1995. We refresh it monthly and count each complaint once per component it names. Data through September 6, 2026.
NHTSA only accepts safety-related complaints. Rattles, paint, infotainment bugs and other annoyances are under-reported here, so this page is a map of what fails in ways owners consider dangerous, not a full reliability score.
Counts are raw. Use the year-over-year shape and the component mix, not the absolute numbers. Where a component maps to parts we stock, the row links to that category filtered to the year you are viewing. Air bag and seat belt complaints link to the recall checker instead, because those repairs are almost always covered.
