Update:
- Mercedes-Benz must face class action claims that its 2015-2019 C-Class vehicles suffer from a manufacturing defect that causes raw fuel to leak within the engine compartment, endangering drivers, a Georgia federal judge ruled.
- On Nov. 1, U.S. District Judge William M. Ray II issued an order denying Mercedes-Benz’ motion to dismiss the class action lawsuit, which drivers refiled after mediation failed.
- The automaker argued that the drivers’ claims should be dismissed because it extended the warranty program for the 2015 to 2019 Mercedes W205 vehicles and C300 models.
- But Judge Ray said the drivers do not simply seek reimbursement for the repairs but also damages to reflect the diminished value of the vehicles.

Consumers who say that 2015-2019 Mercedes-Benz C-Class vehicles, including its popular C300 models, suffer from a manufacturing defect that causes raw fuel to leak within the engine compartment, endangering drivers, are heading to mediation under a new ruling by a federal judge in the class action lawsuit.
U.S. District Judge William M. Ray II issued a six-month stay on the Mercedes-Benz C-Class class action lawsuit. Judge Ray encouraged the plaintiffs and the automaker to try to work out the allegations in mediation, pointing out that Mercedes-Benz extended warranty coverage to the leaky fuel pump defect alleged in the lawsuit.
Mercedes-Benz C-Class class action lawsuit
Lead plaintiffs Nicholas Rosen, Tamer Nassar, and Reginald St. Jean claimed in a class action lawsuit filed in February that Mercedes-Benz is aware of the defect and intentionally conceals it from consumers.
Rosen, Nassar, and St. Jean want to represent a Nationwide Class of current or former owners of 2015-2019 Mercedes-Benz C-Class vehicles.
The Mercedes-Benz vehicles’ propensity to leak fuel can lead to dangerous situations including the inhalation of fumes, vehicle stalling, and vehicle fire, according to the class action lawsuit. Plaintiffs claim Mercedes-Benz is “unable or unwilling” to repair the C-Class vehicles, often telling consumers the repair of fuel system components is not covered under warranty.
This refusal includes towards drivers who have new vehicle warranties and certified pre-owned warranties, which cover 48 months or 50,000 miles and 60 months with unlimited mileage from the in-service date, respectively, say plaintiffs.
“Mercedes-Benz has done nothing to address or correct the Fuel Leak Defect when it manifests in the Class Vehicles,” states the class action lawsuit. “Instead, Mercedes-Benz has denied their requests to provide a repair under warranty and instead forced Class members to pay out of pocket.”
Plaintiffs claim they and Class Members would not have chosen to purchase the vehicles or paid substantially less for them if they had known about the defect.
Rosen, Nassar, and St. Jean allege Mercedes-Benz violated California’s Consumer Legal Remedies Act, the California Business & Professions Code § 17200, the Connecticut Unfair Trade Practices Act, the New Jersey Consumer Fraud Act, the Georgia Fair Business Practices Act, and the Georgia Uniform Deceptive Trade Practices Act.
The plaintiffs are seeking actual, general, special, incidental, statutory, punitive, and consequential damages for themselves and Class Members.
Although the automaker received a temporary reprieve in this case, Mercedes-Benz was part of a nationwide recall this month involving multiple car manufacturers after it found some vehicles had problems with their child restraint systems.

I bought a 2017 Mercedes C300 in June of 2025 it only had 42000 miles on it. In November I had a strong gas smell in the cabin I took it to the mechanic they replaced the fuel line under the car and charged me 500$ I still have a gas smell in the cabin it’s stronger in the morning. I took it back to the mechanic they me there was no leaks anywhere. I know it’s leaking somewhere the smell is vary strong. It’s vary frustrating!
I have a 2016 c300 and been having a gas smell for quite a while. My mechanic told me to go to dealership to get it fixed because it should be covered by an extended warranty but Mercedes declined to cover the repair

I bought a 2017 C300 April 1, 2025, I just started receiving a gas smell sunday November 30, 2025.
I’m receiving a gas smell from the engine area. I own a 2014 Mercedes Benz 2014 CLA 250.
I had a 2016 C300 which also had the gas smell. The dealer repaired that and then not too long later the yellow engine light came on. I spent approx 2k to get it fixed but the dealer didn’t seem to really know what it was. The yellow light came on again abs again intermittently. Last Saturday it ran rough and I had to pull iver and call AAA for a tow.A. Local mechanic that we trust assessed it and said it likely needed a new engine. If only had 129k on it and was dealer maintained on schedule. Rather than repair I sold it to Wheelzey with full disclosure. Please include me in your class action suit. We have all maintenance and repair records. Thank you.
