2014 mercedes E350 these models as well as those from2009-2015. Have recall on subframe but the brake lines rust out and deteriorate as mine has now done. If you go on line you tube etc. You will see the issue and all complaints. I had my subframe replaced under warranty at mercedes of flemington. About 1 1/2 years ago. While it was being serviced they asked me if I wanted to replace brake lines for $1200 since they had this part out job would be easy. So this means mercedes is well aware of the deterioration of these line the man at mb said the metal was inferior and this is result.

This also is dangerous condition should accidents occur the lines because compromised with rust can much easily rupture causing fuels to spew out causing possible explosive condition. I have pictures and can forward.

Fuel smell in the rear of the car, it was checked by a indepent mechanic and the tank is leaking fuel. They said is the fuel filter which is usually faulty in this model. It seems the car can catch fire according to the mechanig. No warnings of the leaking in the dashboard, only the strong smell.

Fuel leakage from the top of the fuel tank, leaking underneath the back seat. I'm told there was a past campaign to fix these issues in the sedan Mercedes Benz E350. The problem was found by the fumes in my garage where I park the vehicle. My smoke and carbon monoxide alarm kept going off inside my house, and I had to call the fire department to help me identify where the fumes were coming from. No warning lamps or messages on the vehicle are present. When I called the dealership they told me there hasn't been a recall on the vehicles. I have had a diagnostic with the dealership.

I notice a strong smell of gas inside my vehicle immensing from the back seat area of my car. And it's stronger everytime bi fill up the gas cap is placed back correctly and no top off ever.

Car was being driven at secondary road speed (~40mph). Engine suddenly began to spudder and misfire terribly. Came to a stop light engine was idled roughly. Accelerated from stop, when check engine light turned on. Car went into limp mode at a very dangerous rail road crossing and left turn intersection. Without acceleration, family was in danger of being hit by train and incoming traffic. Took car to mercedes mechanic. Faulty parts were the camshaft position solenoid valve, ignition cool. Short circuit in one part caused blown ignition fuse and cascading mechanical problems and safety risks. Repair cost so far is $1,100. Concern is the placement of the faulty part. It is exposed to high heat in the motor compartment and poses a fire hazard as well as a personal injury hazard to the occupants and driver.

Fuel smell really strong & a huge fuel leak started on 6/20/2022. The fuel smell was so strong inside the the car I couldn't stay in it. It started leaking before I fueled up my vehicle. Wen to the back of the car and notice a huge puddle of gas. I didn't know anything about this recall until today. I've owed the car for three years. I hope that mercedes will fix this issue. Very dangerous.

Strong gas odor inside cabin,whenever gas tank is full I can smell gas for extended time period. May relate to faulty gas line under the back seat.

Severe gasoline leak smell inside and outside the vehicle. Smell is so bad as to make it impossible to stand next to the vehicle without gasping for air and watering eyes. Due to a fire hazard situation, car can not be parked inside the garage as there is a gas water heater installed in the vicinity. Fuel leak in the feed system has been a known problem in mercedes vehicles in the past. A recall was even issued on E350, 2014 model (recall # 15v792000). However, my vehicle was excluded from the recall on account of mfg. Date not matching with the recall notice. But here we are same problem showing up in the vehicle even after so called fuel leak probe was closed. Took it to the dealer for diagnosis and repair was quoted to be $2297. That's an outrageous amount of money to repair a problem which should not have happened as part of regular wear and tear and is most certainly a fire-hazard and safety issue. My wife and kids ride in this vehicle several times a day and currently I can't let them in this car due to the fear of fire. I would kindly request you to reopen the fuel leak matter with mercedes and look into the matter while I seek a reimbursement of the repair cost from mercedes corporate.

Very strong gas smell enters the cabin and surrounding exterior of the car after fill up. Seems to be a very common problem with this model and follows the same issues with previous years that were filed with the NHTSA and ultimately needed to be repaired by mb. The problem appears to be with the components of the fuel tank immediately under the rear seat. I am at the point where this has become a very dangerous hazard that consumers should know that the manufacturer should address and that consumers should not have to pay for repairs.

For a couple of months when I put my 2014 E350 sport in park it would jerk forward. Never really thought about it being a problem. I was driving my car into my neighbors driveway and went to turn around and just as I went to put the car in reverse, the car propeled forward directly into her tree. If the tree had not been there my car would have went into the front of her house. I am thankful that I am just shaken up and a little sore. I am also thankful that I was the only one in the car during this freak event and that if happened where it did because the 2 other times that I was in my car that day is was in heavy traffic and I would have done major damage to myself and possibly someone else. At first I believe my shoe got caught on the accelerator, but there is no possible way this could be the issue as I was appying it to the brake when the car propelled forward. For as hard as I hit the tree the airbag did not deploy. I was able to drive my car back home with all the coolant leaking from it.

The contact owns a 2014 Mercedes Benz E350. The contact stated that while driving at 65 mph, the vehicle stalled. In addition, the contact noticed the vehicle had been leaking fuel. The vehicle had to be towed to the dealer where it was informed that the failure was related to NHTSA campaign 15v792000 (fuel system, gasoline). The vehicle was repaired under the recall. The manufacturer was made aware of the failure. The failure mileage was approximately 11,000.

I was traveling on highway 26 at approximately 60 mph getting ready to merge onto highway 526, when the entire digital warning panel lit up and then went dead, with the engine inoperable light coming on and asking me to refer to the owners manual. All power was cut from the gas pedal and I was lucky enough to be able to coast to a very small strip of median without being hit by any other vehicles. This is a very heavily trafficked area and charleston being a port city I was very fortunate that the trucks that were around me were able to avoid hitting me. If I had been in another situation, such as pulling out into traffic or trying to cross over a two lane highway the results could have been catastrophic to say the least. I have been told by the dealer that there was a bulletin issued involving the throttle valve actuator, topic # li54. 18-p-058597, version 9. They have not been able to tell me why this happened in the first place, cannot guarantee it will happen again and I would like to know why there was not a recall for this particular potentially life threatening issue? sincerely, lesly jones-noss.

Cruising at 65 mph the esc lights came on and the car lost power. It no longer responded to the accelerator and required that you pull off the road, come to a stop, and restart the car. This same problem has happened 3 more times once at 35 mph on a straight road; once at about 20 mph making a turn and again cruising on an expressway at ~50 mph. This is an extremely dangerous defect, since a failure of this type when entering a highway or trying to overtake another vehicle could cause a high speed accident, resulting in serious injuries or fatalities. The car has been to the dealer twice to fix this, and is now back for the third time.

I bought my first mercedes 20 days ago, I was driving with my kids around 6:30pm when suddenly I smell fuel inside the car and another vehicle approaches me to advised me that my car was leaking fuel all over the road. I took my kids out of the car immediately and I contacted the Mercedes Benz service department for help and I was told by a receptionist that the service department was closed that I need to contact a tow service that way the vehicle can be deliver to the dealership for service. You can't imagined how I felt on the side of the road at that time alone with my 2 kids with a car leaking fuel. I'm very disappointed!!.
