Filed Mar 21, 2023 · Engine, Fuel system · CA

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.

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.
