My car has smelled like gas for the past few years. Also it has not past inspection for the past 2 years. Mercedes said it was due to a defective intake manifold. Paid to replace the intake manifold and Mercedes said 2 new codes appeared. Now the gas tank, fuel pumps, brackets and hoses need to be replaced at a cost of of over 3500. The fuel pumps were replaced in 2014. Not sure why I continue to have problems with fuel pumps and now gas tank. Was informed this year after replacing the intake manifold that there was an extended warranty that concluded December 2022. I think Mercedes should resolve this as other vehicles had this same safety issue.

Very strong gas smell both inside and outside of the car with check engine light on. This happened in May of 2022. Could not park the car inside the garage. Contacted MBUSA, they said there is an extended warranty for this vehicle for this problem, advised me to take it to Mercedes dealer. I took the car to the dealer. They checked it out and said it is not covered under the extended warranty because it has passed the mileage ceiling for PZEV which I do not know what PZEV is. I checked the federal safety agency website, it says 15 years unlimited miles. I had no other choice but to fix the car at the dealer and pay for the cost. A few months later MBUSA sent me a letter telling me although it has passed the mileage I might be eligible for a refund and wanted me to file a claim at the dealership. I did and after over two months the dealer again told me it is not covered. I paid about $1100 for the repair and told MBUSA that the dealer does not honor what the MBUSA letter says. Now even MBUSA does not honor what they wrote me in their own letter. They say if my car was non PZEV it would have been covered? How was it my fault to have a PZEV vehicle? Why did Mercedes had PZEV and non PZEV? How is it the customer fault. Both vehicles have the same issue but why one is covered and the other is not? Please you be the judge.

When car is filled with gas(full) , a gasoline odor consumes my garage. When we open garage all you can smell is gasoline. When the car gets less than 1/2 tank, the fuel odor subsides. Usually when I take it to dealer I have 1/4 tank and smell is hard to detect. This has occurred for over 2 years but smell is getting worse /stronger it starting to give us headaches

Tl* the contact owns a 2008 mercedes-benz e350. The contact stated that upon refueling the vehicle, the contact would smell a strong gasoline odor.

After the second failure, the contact called the manufacturer who informed him that the vehicle was under warranty for a defective fuel pump.

I have a 2008 mercedes e350 pzev model and the issue I came across is a major one. These models in particular have a big reputation on failing fuel pumps, and to make things worse on the pzev versions it can not be fixed unless the whole fuel tanked is swapped with a new one. The fuel pump is located inside the gas tank and its sealed just so there's no way of fixing the issue, on the other hand the non-pzev models have a replaceable pump which reduces the work and money to fix the issue. Mercedes has an applied extended factory warranty for the model w211 which covers this issue until 15years / unlimited miles for non-pzev models and 15years / 150k miles for pzev models. I see this very wrong because the pzev models are super expensive to fix and many people are over the 150k mile mark. This term should have been applied to the pzev models. I purchased this vehicle for $3,200 but to fix this problem it is over than $3,500. I am requesting mercedes to help me on this situation as these cars are well know to fail in that department. As it stands this car is unsafe to drive, it releases lots of raw gas smell and sometimes it will not start. I want mercedes to take full responsibility of this matter because this issue could have been a couple hundred dollar fix if the design after tank wasn't so bad. There are thousands of people complaining about the same issue with the pzev models and most of them are over the 150k mile limit which is not enough considering the age of the vehicles.
