Fuel/propulsion System
11/07/2025
An independent service center diagnosed my car as having a fuel leak stemming from the fuel rail and fuel injectors. This is a fire hazard due to a gas leak. There is a gas smell in the interior cabin that I noticed approximately one month ago. I believe this pertains to NHTSA ID #21V961, and I would like NHTSA to consider including my VIN in this recall.

Unknown Or Other, fuel/propulsion System
03/04/2024
My 2016 Mercedes Benz C300 started giving off funky fumes last year in 2024, now the fumes have turned into the smell of gas in 2025. Everytime that I call the dealership on Rockside Rd./ Broadway, located in Bedford Ohio, they give me an excuse as to why it's not their responsibility to correct the issue. What can I do?

Engine

CHECK ENGINE LIGHT appeared on dash at approximately 72k miles. Had code read and diagnosed by certified mechanic and he had an active code P06DA00(this code signifies an electrical fault, open circuit, or high resistance in the circuit for the oil pump control valve on vehicles with two stage oil pump, which can lead to incorrect oil pressure, which can cause engine damage if not addressed). Vehicle was taken to Harriman Mercedes in New York. They did not acknowledge an active code but wanted to diagnose and repair a stored code for a small evap leak, which was rectified with a new gas cap. After prying about the P06DA00 code, they finally admitted it did have a stored code but to ignore it because it had something to do with domestic and foreign car engine computers issues. How do you ignore an active code with a potentially serious engine issue and told to ignore it. I know for a fact that this is a common problem with these 2.0L engines in these cars for many years.

The contact owns a 2016 Mercedes-Benz C300. The contact stated that there was a gasoline odor inside and outside the vehicle on several occasions, while driving at various speeds and while parked. The contact stated that the vehicle failed to accelerate as needed. The contact stated that there was no warning light illuminated, the fuel consumption increased, with the fuel gauge lowered more quickly. The vehicle was taken to an independent mechanic who saw gasoline pooling near the fuel injector, and the coils were leaking between the fuel injector and the fuel rail, and the fuel rail or possibly the injector seals needed to be replaced. The vehicle was not repaired. The contact believed that the vehicle should be included in a recall. The manufacturer was notified of the failure. The failure mileage was approximately 98,000.
