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. This is a failure on behalf of Mercedes Benz as it is simple to conclude that the issue includes more vehicles than initially recalled. These vehicles need to be included as well.

I'm having the same issues as described in Recall no. 12V557000. However when I called Mercedes they mentioned that my Vin wasn't part of that recall. I don't understand how can that be when my car is 2011-2012 glk350 model as described in recall and I smell gas, can see gas leaking and the flange where my fuel filter is cracked as well as the flange to the fuel pump side. This car as well as many other Mercedes have two separate flanges that are prone to crack and not just the fuel filter side but the fuel pump side as well. there's many forums where they all have complained about this issue. If you can smell gas, there's obviously fuel vapors leaking and not to the mentioned the physical leak that is landing everywhere you drive. This is a serious fire hazard and is extremely harmful to my kids and passengers.

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. I am very afraid of a fire because the tray underneath the car on the passenger side is full of gas & the tray is right over the exhaust. I stuck a large cotton swab in the tray to soak up the liquid & since it smelled like gas I tried to light it. It caught on fire immediately. This is definitely a safety hazard as it can ignite if a spark or lit cigarette would happen to bounce up in there. Yes it is unlikely but I have seen stranger things. The tray holds a large amount of gas and is directly under the gas tank. The check engine light came on and the diagnostic machine says fuel evap control system leak. A mechanic looked at the leak after taking the rear passenger tire off and finding the gas pooling in that tray. Odometer reads 145,000.

Because of the low quality of the plastic, which was used in the fuel pump body on my Glk350, formed a crack on both bodies of the fuel tanks. Fuel is coming out directly under the rear seat and dripping down to the road. This is a safety hazard, and could cause a possibility of fire.

The vehicle did not pass inspection showing a small fuel leak. I noticed a smell of fuel odor coming from outside parked vehicle and noticed a leak coming from underneath the vehicle as well. It appears to leak the most when the gas is full. The vehicle was taken to a certified mechanic who diagnosed that the fuel leak with the fuel pump. The certified mechanic informed the contact that their failure was related to NHTSA campaign number 12V557000 (fuel system, gasoline). I contacted park place Mercedes of grapevine, tx, phone number 843-815-0300) who informed me my vehicle was not included in the recall. The vehicle had not been repaired as of yet. The approximate failure mileage was 56,000. This issue seem to be wider than the initial recall sample. This is very dangerous.

When I fill up my 2011 glk 350 with gas I have a very strong raw gas smell from the vehicle. It is so bad that I am afraid it will cause a fire inside my garage. It goes away as the fuel is run out of the vehicle. I check with Mercedes and with my VIN # it was not on a recall list however many other glk 350 were on a recall list for the same problem. It is recall 12V557000. I feel Mercedes should cover all 2011 glk 350 for this issue as it is a definite safety issue with raw gas leaking. It was also in a bulletin sent to dealers about this issue. NHTSA id 10059568. It is a leaking fuel filter flange. It is also a very dangerous problem!! the fix for it is replace the fuel filter flange and plastic pump also normally at a cost of $1200 at the dealer. Mercedes needs to recall all 2011-2012 glk 350 for this issue in my opinion.

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.
