NHTSA Complaint #11543139 — 2011 MERCEDES-BENZ C300

On 8/3/2023 we could smell a strong gasoline smell inside and outside our 2011 Mercedes C300. We towed the car to a Mercedes specialty repair shop for inspection. The found that the passenger side fuel pump cover (which is a large cylinder assembly actually) was leaking due to cracked plastic. Gas vapors could be detected outside the car, in the trunk, and in the car as the gas tank is right under the back seat. Our mechanic said he had just fixed another Mercedes with the exact same problem. Apparently this is a well known defect and I understand that Mercedes has an extended warranty for later models. We believe the extended warranty should be extended to our 2011 C300 which has only 55,000 miles.
