2012 MERCEDES-BENZ E350 Complaints

Gasoline Fuel System problem of the 2012 Mercedes Benz E350. Driver side fuel leak was excessive. Leak caused an excessive amount of gas to spill while driving on a 600 mile long round trip to St. Louis. The fuel filter sending unit had numerous stress cracks in the plastic. A massive failure was looming. I have pictures and have documented the failure. 2184700194 was the original part and now has changed too 2184700994. A component should be easily inspected to prevent such a dangerous situation. For the past 13 all services work was preformed by Mercedes.

Air bag notice on monitor, Passenger front seat locked in forward position up to the dashboard..

Steering wheel lock module steering wheel was locked in place and vehicle wouldn’t do anything.

The contact owns a 2012 Mercedes-Benz E350. The contact stated while driving 5 MPH, the contact smelled fuel on the interior of the vehicle. No warning lights were illuminated. The contact stated that the dealer was contacted. The vehicle was taken to an independent mechanic where it was diagnosed and determined that the fuel filter sending unit needed to be replaced. The vehicle was being repaired. The contact related the failure to NHTSA Campaign Number: 12V557000 (FUEL SYSTEM, GASOLINE). The manufacturer was notified of the failure and informed the contact that the VIN was not included in the recall. The failure mileage was 124,900.

I have a 2012 E350 with less than 95000 miles and I see these vehicles were recalled in the past for their fuel tank manufacturer malfunction but my VIN number was not included. This car went numerous times to the mechanics and the fuel components fixed but it still leak gas and smells even when I do not drive the car. I spent over $15000 on this matter. This is now becoming a safety issue for me and my neighbors. I don't know what to do. Here is what happened. All began February 2023, I towed the car to an approved MB mechanics who said fixed the car. 9 month later, I brought the car back for the same issue. Strong fuel smell. The attachments for repairs will show the work done. Some repeated and recharged to me. The following year April 2024, I woke up one day with a fas leak all over my drive way and a strong smell of gas. I had the car towed for a repair cost of $7754 total. I am constantly having the same problem with the car and wanted to alert here to bring Mercedes Benz awareness to their faulty parts putting consumer lives at risk.

Recall exists related to a potential issue with the high-pressure fuel pump, which could lead to engine stalling and increase crash risk. My 2012 Mercedes E350 stops the engine in the middle of the road couple of times and for some reason, its stops or shut off the engine completely. The last time I was pulling out on the main road and stop right there. I made a big traffic, and I was scared because I cannot start the car. The guy stops and help me to push out of the road, but we cannot push the vehicle unless someone is inside the car. If I go out, it will automatically go on "park" and cannot push the car. When you check the dashboard the check engine light is not on. 2nd incident I bring this car to Mercedes Benz Dealership, and I told them that there is something wrong in my car, I explain what was wrong but, the guy I talk to, told me that if the check engine light is not coming on, my car is fine. I repeated that the car stops ones in a while when the temperature light is on inside the dashboard and the engine shuts off. He told me if the check engine light turns on then I bring it back. I show the code reading but the same thing he said. I left and went back home and suddenly I get stranded again; I got stock in the middle of the road for 3 to 4 minutes. I start the car and suddenly the car starts and find the nearest place to pull over. I let it call down for couple of hours and start again, the car starts and try to go back home. When I was in the interstate hwy. My car engine shut off, so I quickly pull over, but I was having a hard time to turn the wheel. I believe that this is very unsafe and should have Mercedes Dealer has to repair this issue. I research on the website that 2012 Mercedes Benz E350 have recall to a potential issue with the high- pressure pump and other things like Battery fuse relay box positive terminal and low fuel circuit.

[XXX].The engine intake manifold on our 2012 Mercedes E350 (64,000 miles) EXPLODED with enough force to bend the hood up 2 inches. It was a damp cold morning & the engine had not been started in 12 hours. The car was not locked & the key fob was nowhere close. The fuel level was under 3/4 full. This happened when wife went to get something out of the car and when she pulled the passenger door handle to open - B O O M !!!! If this happened 30 minutes later, I would have been under that hood checking the fluid levels for a trip to San Francisco. I WOULD HAVE BEEN SERIOUSLY HURT OR KILLED!. It was towed to Mercedes-Benz of Carlsbad, Carlsbad California on [XXX] & they have not been able to identify the cause. They could replace the broken parts at the cost of $8,000 but that doesn’t fix the problem. And if it happens again & hurts or kills someone, they could be held liable. Similar intake explosions have occurred on these Mercedes engines but Mercedes is denying any knowledge even though it’s clearly a dangerous design flaw in this intake system.

I am writing in regards to the 5 vehicle recalls that were for the make, and model of my car that is showing as having no recalls for. The recalls involved air bags, air bag software, fuel filter flange, and I am also wondering with the driver headrest deployment module if that is associated with an airbag module; as when I had purchased the vehicle I had found out that both my airbag modules had malfunctioned with showing the srs lights on the dash. I was told that Mercedes of Sarasota, FL had replaced the passenger airbag module by Mercedes of South Orlando. When asked for a printout verification of this repair showing to be completed; they said they couldn’t provide me with this information. As proof of the service to being completed could not be provided. I had tken my car to their to have them look into this, and the tpms sensors showing malfunctioned; communication error message, and they couldn’t figure out what the problem was causing this. I had to take my car to an auto electrician to find out the problem; that I had found out that a 100 amp fusible link had blown, causing all those problems with also the roof wasn’t working. Along with I was smelling fuel. I found out about the recall for these items after getting them repaired out of pocket by the auto electrician Mike from Peak Audio, and Electric, and as to the fuel filter flange I had to pay like $1,200 to replace as they had replaced the fuel level sending unit that include the fuel filter flange. I would like refun; still have the headrest driver side that needs to be replaced. I found out that their is an recall for this make, and model of car that had said the air bag deployment software was under recall for those vehicles; which I believe could have triggered the deployment of the head rest while I was driving; as if I had been near a car; I could have been involved in an accident. I think that this should have an open ticket for repair placed on all 2012 Mercedes E350 Cabriolet Blue Efficiency.
