Every time the car's tank is filled with gas some leaks out on the ground. There is also a strong smell of gas in the cabin. I see there are many other complaints concerning this issue. Will someone please take action and force Mercedes Benz to fix this defective product.

I have a Mercedes GLK 350.When I fill up the gas tank in full I can smell gas. I called the dealer and they refused to fix it because there is no recall in Mercedes GLK 350 and it is not covered by emission warranty. They will charge me $200 just to diagnose the problem

The glk smells like gas any time it's fueled up. I never top it off because if I do, it leaks fuel until I get down to 3/4 of a tank. I took it in to get looked at and the dealership warranty dept. Told me my VIN number was not one of the ones affected by the sameexat type of fuel leak as others in the recall! I am sorry that I ever bought this vehicle, I will never buy Mercedes-Benz again1

Since new the glk would smell like gas any time you fueled up. I never topped it off because the dealer told me that may be a reason you smell the fuel. I took it in to get looked at an they told me it's common it's just the evap system working. That's fine but after a few years anytime I filled up I noticed it would start leaking onto my garage floor. I took it in to the dealer and they told me it's out of warranty by a month an this would cost over a thousand to get fixed. I told them I read that a lot of mb are getting recalled due to the fuel leak. And they told me mine is not one of them. It's so frustrating to buy a car brand new an have fuel leaking out of ur gas tank. I have to fill up to 3/4 of the tank to keep it from leaking. I've been doing that for almost 2 years now.

Everytime I fill up the tank, it smells gas in the garage after it stays overnight. I do not overfill the tank. But, this still persists. Many mb owners I have seen on the mb blogs and inquiries about this have the same issue. This is a potential safety hazard issue that requires immediate saftety recall. Please investigate. Thank you.
