4 Other Fuel System Pump problem of the 2003 Mercedes Benz E500

Failure Date: 07/20/2015

My vehicle started puttering and finally shut off. I had it towed to the nearest Mercedes Benz shop located on independence drive in charlotte. After the diagnostic, I was told that the fuel pump was bad. I informed the service advisor colton and the service manager todd about the extended warranty on the components of the fuel system. I was denied warranty coverage because they stated that the fuel tank had to be cracked before they would honor the warranty. To my understanding if the item is a part of the fuel system components, it should be covered for the warranty. They refused to satisfy the warranty and I ended up not authorizing the repairs. Now because mercedes will not repair the covered part, I have to take it to another repair shop to have it fixed. I think mercedes should reimburse me for my time and parts and labor for not satisfying their extended warranty.

Failure Date: 12/21/2014

While driving home I smelt smoke. I stopped the car to investigate the smell of smoke that was overpowering the now normal scent of gas which filled my vehicle cabin due to a fuel pump leak. When I exited my vehicle I opened up the drivers side rear passenger door to find smoke emitting from that area. I quickly left the immediate vicinity of the smoldering car and when I turned to look back, I saw flames under my car. I proceeded towards the overpass while moving away from the vehicle attempting to find cellular phone signal, I saw my car now being engulfed in flames. (odi number) 10628900.

6 Other Fuel System Pump problem of the 2005 Mercedes Benz E500

Failure Date: 11/24/2014

Bad fuel smell coming into the cab of the vehicle. They have already replaced fuel pump last year and it was smelling so I thought there was something related to that. I went to the mechanic and after they took apart the back seat, they showed me the work they did and the current problem which was a leak in the gas tank from the top bolt that is molded to the plastic tank. He then showed me a stack of tanks about 5 or 6 fuel tanks high, that he said were the tanks that they changed out last week, saying this is a common problem. The rough estimate was $2000. 00.

19 Other Fuel System Pump problem of the 2003 Mercedes Benz E500

Failure Date: 07/23/2012

As reported by many mercedes owners, our mercedes E500 has begun the dreaded leaking fuel pump and sending unit. Upon lifting the backseat and tank covers gas is pooling and leaking all over the top of the tank and onto the ground from these assemblies. These part appears defective and not suited to be overlooked by ntsb. Unfortunately my dealer stated there is not a formal recall yet on these parts, but has heard about the problem many times. What does concern me is there was a recall on the e55 model, but in doing the research just as many E500 owners out there are experiencing the same problems. Please give this high consideration for a recall or further investigation. The well being of owners and drivers is not worth the risk and financial obligations that may occur from a recall. Thank you for your time.

20 Other Fuel System Pump problem of the 2005 Mercedes Benz E500

Failure Date: 01/11/2012

21 Other Fuel System Pump problem of the 2004 Mercedes Benz E500

Failure Date: 09/26/2011

A strong gas smell in the passenger cabin as well as outside driver side passenger door and the check engine light prompted me to take the car to a local dealer. After diagnostic test, dealer indicated there was a leaking fuel purge valve and shut off valve. After a $1,600 quote, I requested they not do the work so I could take it for a second opinion. Was called back later that day and informed of a "miscommunication" and that the car was fixed with a $1,600 bill awaiting me. I worked out a payment agreement with the dealer and never took the car back despite intermittent gas smells in and outside the car and check engine light going on and off. The check engine light came back on for good less than 12 months later. Took car to another local shop where I was told one of the fuel pumps needed to be replaced. $600 later, and 4 more trips back to the shop, the check engine light and strong gas fumes still permeate the car. Took it to shop #3 today and was told there is a crack in the fuel tank. The quote is $1,700. I don't trust the dealer, and believe that the fuel pump replace by shop #2 was not the issue. It appears as if it's been the fuel tank all along. This is clearly a defect in the part as the car has never been in an accident and has less than 70k miles on it currently. It's a safety hazard and with two children, I don't have a choice but to fix the problem. Please let me know if there is anything additional necessary to help conclude this investigation. I'm hoping there will be recourse with mbusa to reimburse it's customers for the faulty part replacement and labor costs. Thank you.

22 Other Fuel System Pump problem of the 2004 Mercedes Benz E500

Failure Date: 08/25/2010

I starting smelling a gassy smell seeping into my house at night and after a few days concluded in had to be coming from the attached garage and subsequently after eliminating all other variables I narrowed it down to the car. I parked it outside for a couple of nights and the smell ceased in the house and garage. I then took the vehicle to pompano mercedes to have them check it out and was informed my seals were bad/leaking at the fuel line connections, so without a choice I had them repaired at a cost of $968. 21 on 9/13/2010. This resolved the problem for about 2 months, then the gassy smell returned. I took the car back to pompano mercedes again and explained that I had the car had the same symptoms of a gassy smell. They checked out the vehicle and informed me at this time I had a different fuel leak and that would require them to replace the entire gas tank and internal fuel pumps and seals at a cost of $3000 this time. Quite unhappy with this diagnosis considering I was just there 2 months prior and thought they had repaired the problem only to find out now it was more encompassing than their first attempt at a fix and it was going to cost a boatload of money to re-repair the problem as I was just over the 50k warranty to boot. With the news of the extended warranty settlement at this time I strongly feel my vehicle issues are as described in the class action suit and I should be entitled to reimbursement for the $968. 21 I spent at mercedes discretion.

23 Other Fuel System Pump problem of the 2004 Mercedes Benz E500

Failure Date: 01/01/2009

There has been a strong gasoline smell following a tank fill that fills the garage with gasoline fumes. This problem has been occuring for at least the last 5 years. I entered 1/1/2009 on the form data as an approximate begin date. The fuel smell can be detected in the vehicle at times, but is extremely strong immediately after fill-up. An internet search has revealed that this is a common problem on all mercedes e class models from 2003-2009. I have asked continually about this problem at the mercedes dealer, now mercedes of natick, formerly foreign motors west in natick, massachusetts. Service personnel have denied that there was/is any pattern or problem and indicated that this problem seemed to affect my car only. Only recently have they indicated that at times they have had to replace the fuel tank and both sending units at an out of pocket cost of $850 -$2000. All this for a problem that current research indicates that mercedes has known about for more than 7 years. A class action lawsuit was filed in texas in 2012 for this exact problem. The dealer has offered no financial assistance in this repair, but did indicate that after I paid for the repair, that they would try to contact Mercedes Benz for assistance. While nice, this still puts the entire financial burden on me with only a hope that assistance would come later. So far I have declined the repair. While some vehicles were included under a voluntary recall in 2008, my vehicle was not one of them. In fact, I have never been contacted by Mercedes Benz for this problem. I asked about this issue only 2 weeks ago, late June 2014, and was told that there is no factory repair campaign or recall at this time. This morning I removed the bench portion of the rear seat, folded back the insulating pad and removed the metal access plate for the left side fuel sending/fuel pump unit. Gas was visible.
