1 Other Fuel System problem

Failure Date: 09/24/2024

This is a pzev vehicle. When the car is filled over 3/4th of the way, the driver's side near the back tire starts to leak the fuel. There was no warning lights, just the smell and the leaks. It's obvious why this is a safety hazard. This was not inspected by anyone other than myself as it was quite obvious after removing the back seat and accessing the sending unit location. This started after I resolved a fuel pump issue (back in March, resolved this month) mercedes refused to handle ($3k) and noticed on or around 9/24/24.

2 Other Fuel System problem

Failure Date: 05/01/2024

On [xxx] I was driving and the vehicles stalled in the middle of the street, I couldn’t start it back. I managed to contact aaa and had the vehicle towed to my home because it around 6pm and auto repair shops were closed. Next morning I had aaa towed the vehicle to a local auto repair shop and they told me that fuel pump failed. It would have been very dangerous if we were driving on the freeway, not to mention I had my 85 year old mother in the passenger seat. Please help me as I am sure what I need to do now. It’s a mercedes-benz model E350 2008. I can be reached at [xxx] my name is [xxx] . My car has 87,200 miles. Thank you in advance for all your helps.

Gasoline smell all times inside of the car.

5 Other Fuel System problem

Failure Date: 05/01/2022

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.

6 Other Fuel System problem

Failure Date: 05/01/2022

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 NHTSA 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.

19 Other Fuel System problem

Failure Date: 06/10/2014

After filling up the gas from gas station, we see gas leak/gas dripping under the car (underneath the rear seat). We can see gas dripping and the smell of the gas inside the car as well as outside the car. When I looked at the internet, there has been lot of incidents reported by plenty of customers and I don't know why mercedes is taking a look at it. It can cause serious fire issues since gas is exposed to air. I hope you will take this seriously. The contact merc dealership where we got this vehicle is 17510 north fwy, houston, TX (281) 305-8970. Thanks.
