Other Fuel System Tank Mounting Problems of Mercedes Benz E320

I filled the gas tank full and on pulling in the garage could smell a strong smell of gasoline. . . Went to get my oil change the next day and the gentleman mentioned he could smell gas coming from my car at valvoline oil change. . . . Very strong smell in the interior of the car as well as when walking around the outside of the car you could smell a strong smell of gas. . . The gentleman from valvoline looked under the car and said there's some type of cover that goes underneath the gas tank itself and put his finger into it and could touch gasoline on his hand. . . I just went onto the internet and read many many complaints of the same thing with this type of car lawsuits have been filed. . . In those complaints the people that brought their car to dealership said that it was very expensive to remedy and that there should have been a recall. . . After driving a little bit and reducing the amount of gasoline in the tank the smell has subsided somewhat. . . Those complaints also mention that it can be very dangerous with this type of leak.

After fuel filter replacement, vehicle operated fine for about 7 miles. While idling a couple of minutes in the driveway upon return from the short trip, the return line hose exiting the fuel filter expanded, ruptured, and sprayed fuel out at a high rate. After hose was repaired, fuel gushed out of evaporative canister discharge tube and purge valve canister. Vise grips placed on the rubber tube leading from the return line to the canister stopped the gusher. New fuel filter that was just installed (pronto pf5416) was suspected to be defective - causing excessive return line fuel volume. With the poor design of the return line plumbing and restriction back to the tank, the excess volume was piling up in the evaporative canister and out the purge valve in a massive gushing leak. Once a second new fuel filter was fitted (purolator f65416), vehicle ran properly again without leakage - however, severe leakage from the top of the evaporative canister was noted during a fillup attempt shortly afterwards. This never occurred in the prior to the filter replacement. From all indications, the design is very poor and susceptible to any conditions which result in excessive return line fuel volume. The amount of fuel pouring out of the top of the evaporative canister assembly and discharge was indeed a fire and environmental hazard - the equivalent of an open fuel pump output discharge. In addition to all of this, during the filter replacement/testing process, loud banging was heard from the tank itself. Removal of the gas cap resulted in a massive pressure release. From my observations as a mechanic with over 25 years experience servicing foreign cars, the ventilation and fuel pressurization system on this vehicle is improperly designed and unsafe. Vehicle was on a lift while being serviced.

Vehicle presented with red light indicating to take vehicle to workshop in red. Braking was extremely difficult, srs system stalled the vehicle, emergency mode was activited,we were unable, at first to turn on the ignition switch. The vehicle operated as if it was paralyzed. We finally got the vehicle to run and turned vehicle into mb dealership. We were informed that the sbc unit was in need of replacement, we were beset with 1,800. 00 repair. The vehicle is very dangerous to drive if you are not prepared for longer stopping distances, thankfully my husband was able to get the vehicle to the dealership. I found myself not strong enough to press on the brake pedal for adequate braking distance. Fuel: upon fueling vehicle, the fuel handle will stop and immense amounts of fuel will spurt out from fuel tank. There is also a smell of gas/fuel in the cabin after fill up. This creates a huge spill and notification to attendant. Takes up a great amount of time to fill up tank. Surprisingly we haven't been charged for fuel spills. Srs: light on for safety response system, shortly after visit at mb dealership. Have not taken vehicle to mb dealership for fear of another expensive repair.

I filled the tank and it leaks on the garage floor at a steady drip underneath the rear driver passenger side tire where the tank sits . . . Notice it leaking from the top of the tank coming down on to the floor. . . I cannot fill the tank and the smell and the amount of gas on the floor I believe is quite hazardous in an enclosed garage underneath a bedroom.

Began noticing gasoline smell in garage. Traced smell to the car. The smell has now intensified that I can smell fuel as soon as I exit the vehicle. The smell is now prevalent regardless of the amount of gas in the tank! it smells really strong in the driver side rear wheel well. I can no longer park the car in my garage for fear of fire. The smell is now becoming noticeable in the cabin as well. My understanding is NHTSA is aware of the problem and Mercedes Benz will not acknowledge a design flaw. I suppose I or some other owner will have to go up in flames before anyone decides to do the right thing. How sad.

Stong order of gas from left side near back seat area , always after fill up , thought just loose gas cap , removed rear seat and left fuel sending unit cover , found puddle of gas on and round gas tank . Was told from dealer parts dept , very common for seal to weep , replaced ,but still same problem , after last fill up , dried around pump and gas just weeped though top of sending unit , hair line crack I assume , will replace sending unit myself . Disappointed that this doesn't meet recall standards per mercedes.

When the gas tank is filled full of fuel a strong odor of fuel is present inside of the car. I have looked under the back seat and seen a small amount of fuel escapes from the fuel system. Since I noticed this I have not filled my car up all the way as long as I don't fill it more than three quarters full the problem does not occur,.

The contact owns 2003 Mercedes Benz E320. The contact stated that there was a strong odor of fuel inside and outside of the vehicle as well as a small amount of fuel leaking onto the ground. The vehicle was taken to an independent mechanic who stated that the fuel tank would need to be replaced. The vehicle had not been repaired. The manufacturer was not notified of the problem. The approximate failure mileage was 110,000.

Our car was purchased off lease around November 2008. It had 47,000 miles on it when we purchased it. We noticed that when we filled the gas tank up the gas fumes were strong in the garage since the time we purchased the car. In March 2012 the check engine light came on while on a trip shortly after that gas tank was filled. I read the manual and stopped by an auto zone and they told me it was probably due to the gas cap being loose and the fuel tank loosing presure and they cleared the warning. The light has come on a few times since then and I have had it cleared twice at auto zone since I did not think there was a big problem and I was in between services. Within the last six months I have had it the mercecedes service department and they told me they did not know why the check engine light was on and that they did not have enough time to find out what was wrong. Yesterday, September 25, 2013, I went to a Mercedes Benz specialists, local mechanic that only works on mercedes and uses mercedes parts, for an annual oil change and checkup and asked him to check out the problem that the mercedes service department did not know what was wrong. He tested the fuel tank using a system to detect leaks and noted that the top of the fuel tank had a crack and I need to replace the fuel tank and it would cost $2,082. Over the past few years I just filled the tank to half or three fourths so it would not emit fumes, however, I filled it up for a trip last week and you could smell the fumes badly in the car. Our car has about 134000 miles on it now.
