While driving the vehicle, noticed a smell of fuel inside the car. Parked the car in my garage and the next morning, noted a heavy smell of fuel in the garage. After some research, discovered a recall on the fuel filters for 2011-2012 Mercedes E350 for the fuel fillers. Took car to dealership and they stated the recall was not associated with my VIN despite my car being the exacted year, make, and model for the recall. I removed the back seat to view the fuel filter and saw fuel puddled inside the car, on top of the fuel filter, under the left side of the rear seat. The risk is twofold. Spark ignited the gas in the vehicle out a spiral ignited the fumes smelled in my garage.

Vehicle is 9 years old, with 73000 miles. Dealer Service has advised that the rear subframe and brake lines are rusting and need to be replaced as a safety issue. Cost quoted was $8800. Mercedes agreed to pick up the cost of the parts and the dealer offered to split the installation cost, bringing my total down to $3150. On-line research reveals this is a common problem across several product lines and has been an issue for 20+ years. Failure at this point could lead to uncontrolled movement of the the rear suspension structure, the rear suspension members, wheels, and electronic sensors in the ABS causing loss of control and brake failure.

Due to the odor of gasoline both inside and outside my car I brought my car to the local Mercedes’ dealership. Upon inspection they found a small crack in my fuel tank which allowed gasoline to leak into another compartment. The dealer stated they would not be able to replace fuel pump without replacing the gasoline because of the “danger and risk of fire”. I believe that the leakage of gasoline and the fumes associated inhaled presents a very real danger, and risk to health. Upon research I found that this is a major issue that has been addressed by your department. After a 3 year investigation this investigation was closed due to the extension of the manufactures warranty to 15 years. My car is 8 months out of the extended warranty. When speaking to Mercedes’ Benz hotline, the representative stated receiving several phone calls recently with reports of the same issue. I appreciate your attention to this matter. I am hoping this case with be reopened, and the manufacturer held responsible for replacing faulty fuel tanks.

Informed by local Mercedes dealer that the vehicle has severe rear brake line corrosion at 55K miles. Stated that the vehicle could suffer loss of braking power if the line(s) ruptured. This is unacceptable for a vehicle with this mileage. According to internet searches this is a widespread problem on 2014 models and earlier. Estimated cost to repair is $3600.

Vehicle fuel system known component issue, fuel pump failure, intermittent. Driving vehicle can lose power at speed, causing potential loss of control as hydraulic assist to steering and braking fails with engine. This known issue has intermittently cause our car to fail to start, or fail in operation. This was a known issue, the manufacturer was allowed to avoid a recall by extending the warranty for this component (fuel pump in fuel tank assembly) to 15 years. Our car started showing this around that time (3 months ago, when extended warranty expired), however we were not then aware of said warranty. Now that we've been two months of diagnosis and discussions with MBUSA Customer Care, they are not willing to replace the known failure point as warranty expired 3 months ago. This should have been a recall from the beginning, and now we, and many others to come, will have the value and usefulness of our vehicles reduced or eliminated. Those not aware of the potential failure of this very expensive part, will be at risk every time they operate their cars at speed on the public highways. NHTSA should never have allowed this warranty extension scheme to substitute for a recall. There is no way to predict failure, and entire fuel tank assembly replacement is <$4,000. Fuel pump is not individually accessible or available for replacement, only entire tank assembly in these PZEV vehicles is available. Mercedes-Benz is shirking responsibility here, and flipping it over to the dealerships and consumers.

The contact owns a 2009 Mercedes-Benz E-350. The contact stated while driving 30 MPH and coming to a complete stop, the vehicle started sputtering and stalled. The contact pushed the vehicle to the side of the roadway. The contact was unable to restart the vehicle after several attempts. The contact towed the vehicle to her residence five days later. The contact used an OBD reader to determine that the failure was associated with the fuel system. The contact replaced the fuel relay and fuses, fuel pump and fuel filter herself; however, the vehicle failed to start. The vehicle was then towed to the dealer and diagnosed with a fuel leak. The contact was informed that the fuel tank needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that the vehicle could not be repaired under an unknown recall because the VIN was not included. The failure mileage was approximately 147,000.

I have the similar issue with my sun roof as described by this entry found on your website below: Started developing (April 2021) a rattle in car's roof along with occasional metal popping sound coming from rear of car. Continued to get worse. Then rattle stopped for a while and so did the metal popping sound. Now ( August, 2021)it sounds like there is a bolt loose in the sunroof area and the metal popping sound is really loud and I think coming from roof. Most of the time when car body twist, like going up a slight incline at an angle when entering a parking lot this incredible loud popping sound resonates throughout the entire car body. Played around on Mercedes website and it appears that Mercedes has problems with sunroof bolts coming loose. This is a safety defect -- if sunroof comes lose at 70 mph it is going to fly off and hurt or kill someone. Also strength of roof is compromised and if have accident where roof protection is needed it will probably fail.

Just been told by the Mercedes Benz Service/Dealership that on my 2011 E-350 which has only about 73,000 miles that rear subframe of the car is so badly rusted that it is a serious safety hazard to drive this car, and it wouldn't pass the PA State Safety inspection. For safety reasons, the MB Service Manager has advised not to drive the vehicle until the issue is fixed. The cost to fix/replace the sub-frame and associated labor charges is quoted is $5400.00. The car has been serviced regularly as recommended by the manufacturer exclusively at the same Mercedes Benz dealership. It is hard to imagine that a company such as Mercedes Benz would make parts that would be rusted and damaged so easily and quickly. This ought to be a flawed part and/or poor-quality material to rust and become a safety hazard. I have now seen many postings on the BenzWorld.org forum who are experiencing this issue. I strongly believe, Mercedes Benz should be held liable and accountable to replace and/or repair the issue at their own cost - there should be a safety recall. Over the years, I have driven many cars for much longer time (over 15 years) and many more miles (over 150,000 miles) but never had such a rusting issue, and such expensive repair/replacement to rectify the issue. It is unfair to the consumers to subject them such safety hazard to themselves and others on the road.

Even though the my Mercedes is a 2010, it has forty three thousand miles and garaged for it's lifetime. The brakes lines are rotted and leak. This is a serious safety issue and should be looked into. I'm sure I'm not not the only person with this issue. [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

Have purchased a 2014 mercedes E350 59k miles. This vehicle has an issue as so do many Mercedes with their rear subframes rotted out at the control arm bracket which causes the rear link/thrust arm to detach from the subframe/axle carrier and posses a danger when breaking due to the rear spindle assembly flexing throwing the wheels out of alignment and could be at risk for a car crack. This vehicle has already been in a minor crash as a result of this issue. I personally have not brought it to Mercedes to get it diagnosed inspected or the police law enforcement but there are many cases online on the Mercedes Benz forums to which this has also happened to. This issue applies to other Mercedes models ranging from 2010 all the way to 2016. Videos of the exact vehicle brought to an independent shop available upon request.

Fuel leaking from rear passanger side tire area. Took vehicle to dealer. Dealer identified faulty fuel tank as source of fuel. This problem has been reported in other Mercedes classes, including a manufacturers recall. My vehicle is 10 years old with only 71,000 miles. Dealer wants over $7,500 to repair. This issue has occured in other Mercedes classes. This is a safety issue as driving with a leaking fiel tank can cause a fire and explosion. Please expedite this issue. Thanks

After the car sits for three or more days, brakes locks up. It takes lots of power to get the brakes to release. It’s a safety concern as the car is parked in the garage with not enough room to maneuver. We never had any car which locks the brakes in this manner. Took it to MB dealer and they say it’s the way brakes are designed. A complete nonsense.

My 2014 Mercedes E350 with 54k miles has a Harmon Kardon sound system. About 4 months ago there was static/popping sound from the rear deck speaker driver side. The radio was turned off but the static sound remained. The popping eventually went away. Today, the static sound came back along with plastic burning that filled the inside of the cabin. This is a safety concern that should be acknowledged as it can cause a fire or electrical shortage. The smoke and scent of burning plastic from the speaker can cause health issues, distract a driver, and lead to a potential fire. Please look into this matter and protect other drivers. Thank you.
