FUEL/PROPULSION SYSTEM
I noticed the strong smell of fuel around the rear of the car especially around the back. Upon inspection I noticed that the corner of the tank on the driver's side was wet with fuel. I took it to my mechanic who on inspecting the car reported that the pump outlet on the driver's side pump (which is accessed from the interior under the back seat) was spraying fuel up against the underside of the car against the rear seat and also noticed that the second pump on the passenger side on top of the tank was also seeping fuel. To have fuel leaking anywhere is dangerous, but to have it happening under the rear seat where my children sit is extremely dangerous. I checked for a recall for this problem with Mercedes but didn't find one on their site. I called them at their corporate HQ and they claimed not having a complaint like this before and didn't want to accept any responsibility for the faulty part/s. This is in need of immediate attention by Mercedes Benz before someone loses their lives because of MB ignoring this serious problem. [XXX]... Phone [XXX] email [XXX] Car fills with strong fuel vapors with raw fuel collecting on top of fuel pump Many more reports for same problem I found online that Mercedes would not react to, here is a typical one... Other Fuel System Pump problem of the 2012 Mercedes Benz E350 Date: 06/01/2020 1) My vehicle is emitting a very strong fuel smell and possible leak coming from the fuel pump. This is located under the rear seat, which had a recall. I believe that the item is faulty and should replace once again. I reached out to the dealership and to mb corp; but they do not want to take responsibility for their faulty design and product. The vehicle is not safe to drive with the strong vapors, which are dangerous to health. Also, I am forced to leave the vehicle outside of the garage because of my fear that this will cause a fire or explosion, resulting in massive house destruction and possible death.

FUEL/PROPULSION SYSTEM, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, ELECTRICAL SYSTEM
There are three main issues: As the weather got cold here in NJ, whenever the car is started in the morning, there is a strong fuel smell inside the cabin. Also there is a lot of fumes that smell gasoline. I think it is safety issue. The auto braking does not seem to operate right. I do not see any error message, but it had never tried to avoid a collision when I have tried other cars that would have normally applied the brakes in those situations. The garage door opening function does not work as soon as the ignition is turned off. This is an electrical issue in my view.

The contact owned a 2011 Mercedes-Benz E350. The contact stated that while his daughter was driving approximately 30 - 35 MPH, another vehicle crashed into the driver's side front door. The contact stated that the steering wheel and knee air bags deployed upon impact. The contact was unaware of the side curtain air bags had deployed; and if so, did the Emergency Response Unit cut away the curtain air bags to remove his daughter from the vehicle prior to his arrival. The contact stated that the driver’s side door was totally smashed but he did not see where the side curtain air bags might have deployed. The contact's daughter was transported by ambulance to the hospital with a fractured and dislocated pelvic bone in four locations and a fractured left arm. A police report was filed. The vehicle was towed to a salvage yard and deemed totaled by the insurance company. The manufacturer was not made aware of the failure. The failure mileage was approximately 130,000.

FUEL/PROPULSION SYSTEM
Noticed strong gasoline odor in left rear wheel well after filling the vehicle with fuel. Since the vehicle had just been repaired for an unrelated issue at a local Mercedes dealer, I took it back to them for troubleshooting. They diagnosed the problem as a leak at the seal on the fuel pump in the tank. I researched this issue and found it is a recurring problem for which Mercedes had offered a warranty extension of 15 years. This extension expired for my vehicle in July 2020. Cost to repair was $3,256 as after a 10% discount. I was not informed of this issue or the extended warranty despite having the vehicle serviced at Mercedes dealers multiple times since purchasing it in 2008.

POWER TRAIN, ELECTRICAL SYSTEM
The camshaft position sensors leak oil into wiring harness. The oil circulates to other engine sensors and the ECU(engine control computer). Oil in the other sensors and the ECU causes the car to stop operating or operate erratically while driving. a real problem. This is a safety issue there should not be oil leaking into the ECU! The mercedes dealer replaced the leaking camshaft position sensors and confirmed oil had leaked into the ECU and wiring harness on december 13,2021. They recommended replacing the wiring harness and ECU at cost of $6500. I have the replaced bad sensors. Mercedes says they have no culpability in this or a fix. The mercedes complaint number is #23264730932. The previous mercedes engine generation had the same problem and mercedes did a recall on that engine.

SEATS
I drove a short distance and started to smell burning, and saw some smoke in the cabin. I immediately pulled over and shut down the car. I called my husband and when he arrived we discovered that my driver's seat back had burned through from the seat heater. Luckily I was not injured and the burning did not spread, I assume because I was able to stop quickly and get out.

The transmission shifts hard, with cluck. This is a know problem, according to the Mercedes service manager. My question is why hasn't the manufacturer been made to recall or at least repair it at NO cost to the owner? This is a expensive repair.
