When owners complained
A spike years after the car went on sale usually means a part wearing
out on schedule across the whole fleet — the kind of pattern no single
owner can see from inside their own car.

NHTSA investigations into the 2007 Mercedes Benz E350
An investigation is the step before a recall: the agency has seen enough
complaints to look into a pattern itself. An open one means it thinks
something may be wrong and nothing has been fixed yet.

FUEL/PROPULSION SYSTEM
Recently my wife and I noticed a very strong fuel smell from cabin of this car. When I inspected and lifted the seat there was a puddle of fuel leaked over the sending unit. This is extremely dangerous and potentially deadly for my family especially with 2 young children who are always seating in back seat. Upon checking with Benzel Busch Mercedes dealer in Englewood New Jersey, they said they cannot fix my issue because my warranty has expired. I am now writing to you to help me as I feel this should strictly be a recall and Mercedes USA should be required to fix this leak free of charge. Please understand that out of pocket will be more than $8,000 for this repair and I do have the means to come up with that amount of money. Upon checking on internet there are many E class Mercedes Benz between years 2003-2009 that have this issue. Could you please help me resolve this matter especially this being an extremely dangerous situation. I can be contacted via email: [XXX] or phone: [XXX] . Thank You Sincerely [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ENGINE
Vehicle began shaking on the highway. It was coming from under the front hood and was shaking the steering wheel. The check engine light came on. I pulled over and had it towed to the Mercedes repair shop. They said it was related to a bad balance shaft and that it was a systemic problem with the engine in certain Mercedes e350s. I was told I needed to replace the camshaft and it would cost $6,000!!! After some research, it looks like Mercedes agreed, back in 2015, to cover only certain of these Mercedes, but there was no recall. I could have been killed if I was rear ended.

FUEL/PROPULSION SYSTEM
Fuel tank fuel leak, NHTSA Action Number EA13003 I purchased a 2007 Mercedes E Class used a few months ago, and recently I noticed a fuel leak, strong fuel smell outside of vehicle when fuel tank is filled higher. More fuel means more fuel odor. Upon research, it seems like there was a warranty extension for 15 years, and with my luck, warranty extension ran out just after I bought the car but before I noticed the problem. As fuel is a safety issue and can easily ignite, and also affects emissions, I feel like the remedy should not just be a 15 year warranty extension, but longer as cars are staying on the road longer and longer. I'm sure I'm not the only one with this issue out of warranty extension period.

FUEL/PROPULSION SYSTEM
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.

FUEL/PROPULSION SYSTEM
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.

FUEL/PROPULSION SYSTEM
The component/s that have failed are (reputedly) the fuel system resulting in significant fuel fumes permeating into the cabin of the vehicle as well as being very evident around the rear outside of the vehicle. This seems to be more obvious after the car has been filled with fuel. Having fuel fumes leaking into the cabin of the car should be self evident as a risk to anyone travelling in the vehicle, especially in the rear seats. The fumes eminating from the car, externally, are a potential fire hazard should anyone walk by with a cigarette or naked flame. This is an on going problem well known to Mercedes Benz and one that should have been the subject of immediate recalls by MB and not subject to a Mileage, Time Frame or VIN number. Why should I, or anyone, have to foot a fairly significant bill, for fixing a manufacturing fault just because the previous owners didn't get the problem fixed and I purchased the vehicle after some 15 year warranty time frame? This issue could result in someone's death if Mercedes is not forced to remedy it and by remedy it I mean for ALL 2007 E350's to be recalled unconditionally. Consumer would like to amend the complaint to include the recall of ALL Mercedes E350 for the years 2006 and 2009 for inspection of the cause of the problem and the repair of those vehicles where repairs are needed at Mercedes Benz cost.
