2012 MERCEDES-BENZ E350 Complaints

In having maintenance on my vehicle, the dealer advised that the subframe is corroding and needs to be replaced. I searched several Mercedes forums and found a number of owners citing similar corroding subframes yet no other undercarriage components showed rust or corrosion. All owners felt that this should be remedied by Mercedes before a failure causes injuries. Forum participants suggested and encouraged to file a complaint to NHTSA for investigation.

Camshaft sensors and solenoid leak oil internally which then gets into the sensors electrical connector. From the the oil enters the engine wire harness through capillary action maki g it’s way to other sensors and ultimately the DME (Digital Motor Electronics). This can cause February DME to fail which in turn can make the engine stop running.

Recently, I took my 2012 Mercedes E350 4Matic for an oil change and after inspecting the vehicle, I was informed by my mechanic that the car had a rusted sub-frame, with visible holes near the right rear wheel. I was told this needed to be immediately addressed as it was a safety issue. He explained that if not fixed, the wheel could detach from the vehicle while driving and could result in a crash or serious injury/death. My mechanic indicated that Mercedes Benz of America is aware of this issue and they do not offer any assistance with the necessary repair. However, I did some research online and learned that if you own a Mercedes, have this same issue and also live in Germany, you can take it to a dealer for a free repair. I find it outrageous that this is not a valid safety recall and even more so, having to pay nearly 3K for the repair in order to make the car safe to drive.

The incident was not the vehicle persa but passengers riding in back seat experienced nausea and headaches. Found gas fumes emitting from vehicle. As time progressed fumes got worse and fuel mileage performance worsened. Gas consumption was extremely bad. Car was taken in for oil change and absolutely no gas leaks were found and technician showed me the under carriage of car. Nothing showing on the OBD. Afraid car will catch fire. Not driving as of today.

There is a strong smell of gas inside and outside of the vehicle. Gas is being consumed at a faster rate than usual. No warning lights have come on inside the care. The smell is strong and is affecting all passengers (headaches, nausea) including children and toddlers.

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.

The contact owns a 2012 Mercedes-Benz E350. The contact stated that upon exiting the vehicle, an abnormal fuel odor was detected. The contact took the vehicle to the dealer and was provided an estimate for a diagnostic test. Upon investigation, the contact discovered NHTSA Campaign Number: 12V557000 (Fuel System, Gasoline) which he linked to the failure. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 150,000.

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

The chrome handle on my driver's seat is peeling off and very sharp. It cut my inner wrist really bad last week. I searched online and found many people having the same issues. I was quoted at around $400 to fix this one little handle and I don't have that amount of money right now. This is serious danger and needs to be fixed immediately and it scares me to think of doing it again and cutting into the artery or nerves in that area of my wrist. 1) Yes, you can inspect it or I can send pictures in. 2) The risk it puts on me is cutting my wrist and/or hand, infection, stitches, pain, not being able to work, nerve damage, medical bills, etc 3) There are many accounts online of people experiencing this same problem. I'm surprised someone hasn't gotten seriously hurt from it already. 4) It has been inspected by a service and repair center that immediately told me to be very careful due to the high possibility of cutting me 5) No warning lamps or messages

I found that the subframe had been recalled in other countries, but not in the united states? The large number of failures on this subframe across multiple models is concerning. This is a gross failure of a major safety component that can cause serious injury or death. My research showed this part has been recalled in Canada; MBUSA feels the need to wait to do so until a serious injury or death has occurred. The defective subframe is known and the new part’s design has been amended to take into account this rust issue. This is especially concerning considering the recent recall on the brake boosters due to advanced corrosion. MBUSA’s decision exhibits a lack of accountability for a defective part and this issue needs to be promptly addressed for the safety of its customers.
