The dealer in Hawai’i refuse to honor the recall warranty. It’s traveling a bomb.

This complaint relates to a prior government investigation and related extension of warranty. The government investigation determined leaks could occur from the gas tank pressure sensor, the outlet of the gas tank filling limiter valve and at the top of the fuel pump. Determined leaks could occur from the gas tank pressure sensor, the outlet of the gas tank filling limiter valve and at the top of the fuel pump. As a result, benz extended its warranty to 15 years on gas tank components in 2003-2009 e-class vehicles and 2006-2011 cls-class vehicles. Consistent with the problem, my fuel pump failed last week; the car would not start. I had the car towed to oakland mercedes for service under the warranty. Benz was notified and inspected the car last wednesday. The dealer took possession on friday. I have called the service dept many times to learn status of the car. Benz tells me the car still has not even been assigned a service advisor. They refuse to give me any information re the status of my car and when it will be repaired. This amounts to a refusal to fulfill their promises given upon the discovery of their faulty fuel tanks.

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.....updated 10/15/15

The design of fuel pump in all the mercedes benz is very very defective , the company has shown gross negligence to safety of consumers, when ever I fill up the fuel tank , it starts leaking and starts emitting very foul smell in side and out side the car, I think if there is too much leakage of gas which is fitted under the back seats of car , if there is smoker passenger , the car can catch fire right away, I have complained to the dealer to fix this problem , the do not want to cover under warranty for safety , because the car is more than 4 years old and the mileage is more than 50,000, I complained to the head office in new jersey , they suggested me to replace the tank , and pay for it ,the estimate is about $4000.00 , since it is safety issue they should recall all the cars, which are in thousands with the same defect, I hope you can take care of this problem or file a class law suit to be files again the company for gross negligence.

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.

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. Re: (odi number) is: 10628900.

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.
