general problems of the 2012 Mercedes Benz CLS550

For several months I been smelling different odors from my 2012 Cls550, getting stronger as the weeks go by now smelling like gas, would noticed puddles whenever I parked from rear driver side area towards middle, just got the news from the mechanic that the driver side fuel gas pump is cracked and leaking gas and passenger side is also cracked. Labor + parts $1,660. 00. .

There is a strong odor of gasoline coming from the drivers side rear. I conducted a google search on the issue and there are a lot of instances of the same thing. It appears to be the gas tank sending unit, they have a tendency to crack and leak.

I have Mercedes Benz cls 550. Whenever I fill up a tank full, I smell gas in the car and in my garage. After researching the cause of this issue , I found its a common issue with Mercedes Benz older vehicles where the fuel sender unit cracks and start leaking gas which is located under the rear seat driver side. Mercedes benz sent a recall notice for same problem for older vehicles from 2006-2008 to fix this issue. Below are the steps to reproduce the issue 1. Fill the car up. 2. Drive straight home. 3. Park in the driveway. 4. Take rear seat out(pull up on the leading edge of the lower cushion. . . There are 2 tabs to depress then the seat comes up) 5. 8mm socket and take the drivers side inspection cover off. 6. There will be a fuel lake around that sender.

Premature rusting on brake and fuel lines which lead to further issues with driveability and saftey. This us caused by the same defects leading to the premature rust on the subframe that can cause a serious wreck on the interstate.

Unknown every time the car is refueled there is a very strong smell of gasoline in and around the vehicle. If you check carcompliants. Com the are many complaints about this defect. . In the article @ car complaints . Com the nhsta claims it knows about the problem but since Mercedes Benz has completely ignored the this dangerous situation and neither of you have not followed thru with Mercedes Benz's offer to extended a warranty to 15 years for all these cars , ie e class, Cls550 and others, mb denies this is a proplem ,the NHTSA is part of the issue since they have not enforced the promise by Mercedes Benz to recall and extend this all current owners of these vehicles , since they refuse to acknowledge this issue my next step is a major class action against mb and nhsta for neglince in following up on mb promises which were made in return for the nhsta not enforcing a recall of these vehicles.
