Other Fuel System Tank Assembly problems of the 2008 Mercedes Benz E350

Leaking gas tank pvez, mercedes will not replace it, was under recall.

My mbz E350 is leaking fuel. Very strong smell both from inside and outside. I believe this is extremely dangerous to the driver and or passenger in my car. Also, when gas tank gets filled up, my E350 engine will start but it will die within 5 to 7 seconds. I've contacted mbz USA to inquire about the issue, I was informed that there's no extended warranty available to address the issue. But I've couple of documents related to same issue in which mbz stated that they're extend the warranty to fuel components.

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.

After I filled the gasoline tank I noticed a strong gasoline smell inside the cabin. I got a bad headache from the fumes before I got home. I did not smell any gas in the trunk, engine compartment or in the fuel filler door. I ventilated the cabin and tried to determine where the smell was coming from. It seemed to be under the drivers seat or back seat. Even after sitting all night and having all the windows open all day it still wreaks of gasoline inside. The smell has not left the cabin and I am afraid to drive the car.

After refueling my car's gas tank I began to smell gas from driver/rear side when car is parked in garage. The smell disappears after about 50 miles of driving, but it comes back after refuel.

Fuel sending unit leaks when gas tank is filled. . . Gasoline leaks onto top of sending unit allowing a strong smell of gasoline around car and in garage. . . After burning to about 3/4's of a tank smell dissipates. . If lifting backseat and removing 6 screws and coverplate fuel can be seen pooled on top of sending unit. . Extended warranty (15 years ) on other mercedes vehicles with same year groups experiencing the same symptoms/problems but not our particular model. . . Don't understand why. . . This is a defective design. . . Been driving 40+ years do a lot of work on own vehicles and have only seen this problem 1 other time on our 2006 Chrysler pacifica ( both tanks) same type of setup. . . This was when they were doing joint development with daimler. . . Same faulty design. . . . Dangerous!!!!!.

When I fill the gas tank and park the car in the garage I get a heavy smell of gas around the rear of the car. No smell from inside. I see no leaking onto the ground.

The fuel tank leaks strong gasoline vapor into the passenger compartment and outside the vehicle creating a fire hazard and imperils the driver's ability to properly breathe. The vapors are strongest everytime the fuel tank is filled over half way. Current repairs are going to cost $3000. The mechanic says the root cause is the California emissions required components that are nonstandard. There are no pictures as the leaky fuel tank is concealed under the back seat, below where my children sit.

When you fill up the gas tank, there is a very strong fuel odor in and outside of the vehicle to the point where the vehicle cannot be parked inside a garage and when driven the windows need to be rolled down. On 9/4/14, mb issued a warranty extension for this very problem, however, mb is now saying that my vehicle is a pzev model car which is exempt from the 9/4/14 warranty extension. This makes absolutely no sense as it is the same issue that many mb owners have complained about and there is no difference between a pzev model to a non pzev model (only in the sense of the catalytic converter which is not in issue). The cost is over $3,000 to fix what is really a defective and unsafe product. The part which is leaking fuel is a "left side fuel level sender assembly". This is an integral part of the gas tank. Based upon the 9/4/14 extended warranty letter from mb, the NHTSA was satisfied that the extended warranty would fix this problem. But what mb was able to do was to limit the applicability of the 9/4/14 extended warranty to only non-pzsev vehicles which I am sure eliminated tens of thousands of vehicles from the extended warranty. Moreover, there is no indication that the vehicle is a psev vehicle (other than what mb has internally). The 9/4/14 extended warranty should apply to all E350 vehicles model year 2003-2009. There is absolutely no reason to exclude a vehicle because it is allegedly a pzev vehicle. It is the same fuel leak/odor issue. Dealership will not fix under warranty and the corporate office has denied warranty coverage. Please reopen your investigation and get to the bottom of this clearly defective and dangerous situation. Clearly mb recognized this as a problem and that is why they issued the 9/4/14 warranty extension but then slipped in the exclusion for pzev vehicles. There is no reason to treat a pzev vehicle any differently.

I smelled strong gas smell a few days ago. I took my car to mercedes arrowhead located in arizona yesterday. They informed me that the problem would be covered under a 15 year warranty (fuel tank had started leaking). Today they called me and said that the leak had saturated to my back seats and that it wasn't covered because I had taken too long to call them and that's why the back seats were saturated with gas (I didn't know that my seats were saturated with gas until I started to smell it through my vents while ac was blowing). Now, I am being asked to pay almost $500 to replace the pads and deafening material as they told me it wasn't covered by warranty even though it was caused by a defective fuel tank. At this point I'm not sure if there have been any health related issues for myself and my 2 kids who normally sit in the back of the car who has been inhaling the gas fumes for an unknown length of time.

Filled my tank, parked in my garage, gas smell was all over garage and all over inside the car. The car was leaking gas from under the back seat, in the sending unit. This is really dangerous and shameful of Mercedes Benz to have this defect, which I later found out from a lot of posting online.

Each time I fill up my gas tank (I do not top off), I smell gas for about 1 week in my garage. The odor has gotten so strong, I can smell the gas in my house. I started parking outside my garage until the smell disappeared. I took it to the dealer which cost me $750 to repair. It was the gas tank sealer which was leaking when I filled up my gas tank. After researching on the internet I found this to be a common problem, yet no recall notice was sent to me. I would like my $750 plus damages to my health of smelling the gas fumes in my garage and my home. Not to mention the danger of the damage a spark could have done.

Beginning approximately Nov 2014, I started noticing a strong fuel smell in my garage. The odor seemed to be stronger when I filled the car with gas. By December 2014, the fuel smell permeated to my kitchen, through the garage because the smell was so strong. My husband advised me to park the car outside because he was fearful the car would explode with the other chemicals near and around the vehicle. I called Mercedes Benz (mb) headquarters on two occassions telling them about my problem. They advised me that there would be 'extended warranty' letters issued in late January or early February 2015 that would provide me with reimbursement options and that they recommended getting it fixed ASAP. Therefore, January 13, 2015 Mercedes Benz of san antonio fixed my fuel tank and I paid $3,132. 03 for the repair. I later filed a complaint with the NHTSA in January. The odi# is 10669386. When I didn't receive my extended warranty letter, I decided to email mb to see if the letters had been sent. They informed me the letters were being sent. Today, March 25, 2015, I decided to call mb headquarters(again) to see what the delay was in sending my letter. Mb informed me I didn't receive a warranty letter because my 2008 E350 was a partial zero emmissions vehicle (pzev) and those 'labeled' vehicles were not covered under the warranty. I am distraught over this decision and feel I am being wrongly excluded from the extended warranty. My car is good for the environment and I'm being punished for it. I need assistance in any possible for reimbursement of my faulty gas tank. Not sure what the emmissions part plays in this? please help!!.

Vehicle diagnosed with a leaking fuel tank.

I purchased the vehicle used in may of 2014 from a non-mercedes dealer. Towards the end of December of 2014, I noticed a strong odor of gas in our garage every time I filled up the tank. The odor would dissipate after the gas level went down but the strong odor returned every time I filled up the tank. I did notice moisture on the garage floor but it would evaporate by the time I drove back into the garage so I didn't think much of it. The odor was so strong that I finally took the car to my independent mercedes repair shop to have it checked out. It turns out that there is a defective seal on the gas tank which requires the entire tank to be replaced to the tune of $2200 just for the gas tank-no labor included yet. Fortunately, I purchased an extended warranty but the company is sending out an inspector to my mechanic to verify that a new tank needs to be replaced in a 2008 mercedes. In other words, they want to dispute the repair. Based on my research, multiple lawsuits have been filed in various states on this exact issue. This appears to be a common problem with the year and model which should result in a recall against Mercedes Benz to cover this defective gas tank/seal. Thank you.

Fuel smell. Took vehicle to dealership and they stated that I need the fuel tank replaced and the fuel level sensor on the left side was leaking. Repair cost estimated $3000. 00.

Approximately 3 months ago I noticed a strong smell of gas coming from the left rear wheel well, every time I filled up the fuel tank on my 2008 mbenz e 350. I park the car in my garage and the smell gets very strong overnight. The smell of gas subsides when the tank is about 3/4 full. I have done some research on line and seems like this is a common and serious problem that Mercedes Benz refuses to acknowledge and repair free of charge to the consumer. I am specially concerned because my home water heater is in the garage were I keep my car overnite.

Starting approximately September/October 2014, my car smells like gasoline inside and outside the car when I feel up the fuel tank. When the car is parked in the garage, entire garage smelled like gasoline as well. The smell usually went away in a few days and the smell wasn't too bad in the beginning and I thought I was overreacting. However, on 12/19/14, immediately after I filled up the fuel tank, the smell was so bad and I had a terrible headache from smelling the gasolin while I drove the car. So I decided to take the car into the dealership and was later informed that there are two leaks in fuel tank and another leak in transmission connector. I was charged about $3,500 for the repair.

There is a strong smell of fuel vapor that is noticeable both inside and outside the car, particularly when the gas tank is full. An evap test shows that there is a gasket near/on top of the gas tank under the rear passenger seat that shows signs of a fuel leak. There are no signs of a recall that I can find online and mercedes wants to charge $2100+ just for parts for a replacement fuel tank for something that I feel is hazardous to our health and should have been resolved by mercedes.

The contact owns a 2008 Mercedes Benz E350. After the contact filled up the fuel tank, fuel fumes were present in and around the vehicle. While the vehicle was parked inside the garage, fuel leaked from the rear of the vehicle onto the garage floor. The vehicle was not diagnosed or repaired. The manufacturer was not notified. The failure mileage was 85,874.

The contact owns a 2008 Mercedes Benz e-350. The contact stated that after refueling, a strong odor of fuel was present on the rear left side of the vehicle. The vehicle was taken to the dealer. The technician diagnosed that the fuel tank needed to be replaced. No repairs were made to the vehicle. The manufacturer was not made aware of the failure. The failure mileage was 90,000.

Lately, each time I fill the gas tank, strong smell of gas fills the garage till I use up some of the gas in the tank, driving the car. The smell seems to come from driver side rear wheel area. I noticed NHTSA started an investigation about a year ago. I don't understand why it has not been concluded yet and how all these complaints of similar nature, have not been addressed. Mbnz should be held accountable for their engineering and design. As some noted, their cars were fixed under warranty, so mbnz knows about this problem and seems to choose to ignore. This is where NHTSA is supposed to come in and protect the consumers of these so called luxury ( expensive) cars.

The gas gauge randomly shows incorrect fuel level remaining. This makes it difficult to know how much gas and distance/miles remain before a refill is needed. After a full refill the gauge seems to accurately show a full tank. Randomly, when starting the car, the gauge sometimes shows incorrect fuel levels at empty or much less than actual. This sometimes corrected via restarting car. Sometimes restarting does not correct the gauge.

The contact owns a 2007 Mercedes Benz E350. The contact noticed that the top portion of the fuel tank was leaking gasoline onto the ground. The vehicle was taken to an authorized dealer, who informed the contact that the entire fuel tank would need to be replaced. The vehicle was not repaired. The manufacturer was not notified of the defect. The approximate failure mileage was 60,000. The VIN was not available.

Gas tank fuel sending unit failure causing inaccurate readings. One incident my wife was driving on the freeway in the fast lane and gas gauge indicated 1/2 tank of fuel remaining and car stalled because of no fuel causing a very unsafe situation due to no area to pull over safely. Please reference NHTSA action number: pe12001.

My wife and I noticed the strong smell of gasoline each time we bought gas and filled up the tank. Have mentioned this numerous times to personnel at the dealership and every person just expressed puzzlement over the problem and offered to take a look at the car and see what the cause might be. I finally scheduled an appointment about a year later to correct this issue or at least fine the cause because the odor was getting stronger. . . . Especially because the car is parked in the garage. The dealership called me and said it would cost about $2000 to repair the seals but they would split the cost with me. They said if I did not repair the seals the car was still safe to drive. . . We just could not fill up the tank. I went ahead with the repairs but searched the internet and found numerous other complaints on the problem and the ongoing class action lawsuit in the northern district of georgia and the Jun 16, 2013 request by NHTSA for information due to 528 similar complaints. . . . Please add this complaint to the previous 528. I think someone at mercedes should have been aware of the ongoing question of tank leakage. . . . The car is not safe to drive with a leaking tank.

Every time I fill up the fuel tank, the outside of the car smells of gas till the fuel comes down to about three quarter tank. The gas odor is especially perceptible in the morning when I walk into the garage. As a precaution I started parking the car outside the house for a few days after I fill the tank.

The smell of gas fumes from my mercedes was prevalent in my garage after refueling for a number of weeks before taking it in to Mercedes Benz of chandler to identify the problem. I took the car in for servicing on September 13, 2012. Mercedes identified the problem as a crack in the fuel tank and verified that it was a problem with the tank and not caused by an outside influence (road debris or similar). Mercedes replaced the gas tank at a cost of $2,759. 10 (after discounts) as it was a potential hazard. I have not had any other problems with the gas tank since.
