Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Gasoline smell when fuel tank is full. I removed my rear seats and removed access panels to fuel filter/pumps...and discovered the passenger side access panel had gasoline on the unit and surrounding area. Somehow, there is a gasoline leak coming from that passenger side unit. I did not take any photos since I did not want any active electronics near the gasoline and gasoline fumes.”

My steering column and handling seems out of alignment column feels shaken and faulty and difficult to handle at times at others times”
NHTSA complaint #11164235, filed 2018-12, 52,700 miles“After a fuel fill-up, I smell fuel inside the cabin and outside by the gas tank opening. This causes a constant stress..., what if there is a fire? I heard and read so many similar complains and concerns. This should constitute for a RECALL. What is the responsibility of NHTSA to the consumer's safety.”
NHTSA complaint #11607580, filed 2024-08“Fuel/Propulsion System - There is a gas leaking from somewhere above the gas tank. I did not have this fixed yet because I see a recall for this but my VIN wasn't included in the initial recall. There are 17 other complaints on here for the same issue but we haven't been included in the recall as of today 1/2/2023. The recall that fixed other 2011 GLK 350s is NHTSA CAMPAIGN NUMBER: 12V557000 (FUEL SYSTEM, GASOLINE). My car is available for inspection upon request. …”
NHTSA complaint #11499874, filed 2023-01“I noticed the smell of fuel coming from my vehicle, specifically when I top off at the gas station. This is dangerous as fuel can combust if ignited. I took the vehicle to be service, to find out about the fuel odor and was advised of the NHTSA recall. Upon researching I see that although the NHTSA recall #12V557000 specifically covers this issue, when entering my VIN, the recall does not appear for MY specific vehicle, which is a 2011 GLK-350. It appears there are several affected vehicles not included in the recall. …”
