2012 MERCEDES BENZ E350 Unknown Or Other Problems

The rear subframe got separated from chassis. I was driving to work and had to hard brake to void a collision with another vehicle all of a sudden vehicle shifted to the left and I ended up on a curb. Further inspection vehicle`s rear subframe rotted out due to rust. Also, both rear brake lines from abs module to calipers are damaged due to corrosion. I ended up replacing both brake lines and did not think too much of it and now I see a lot of people complaining about both brake line corrosion and subframe separation or excessive rust, casing rear subframe to fail. It is a very serios safety issue and Mercedes should hold accountable for these failures. My vehicle is 2012 Mercedes E350 and only has 118k miles on odometer. I have attached pictures for the rear subframe for your review, but I did not take any pictures of the brake lines due to limited space to get my camera between the body and the rear subframe.

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.

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.

The fuel pump filter failed and myself and grandchildren became sickened by the fumes. Once the back seat was removed and inspected by an independent source you could see how the gas had leaked into this area. There was no warning lights or messages that had appeared. This problem could easily ignited a dangerous fire situation.

I purchased the car late April. I drove the car for three or four days and started noticing a rattling coming the front right part of the car (passenger side.). I chatted with the warranty company (SilverRock.). They asked me to take it to a Meineke auto repair facility in Olympia, WA. Meinke’s mechanic diagnosed it as a loose component involving the brake caliper. He informed me they were covering it under the warranty, & asked me to bring the car back on Wednesday as he was short staffed. I brought the car back on Wednesday, it was there all day. He called late in the afternoon and informed me they found the problem and that SilverRock had amended the claim and refused to cover it. Told me it needed new brakes for 800+ bucks. That being said it was also sold to me with gouges out of several tires. Of which I have photos. This is inexcusable it is also a safety issue.

My check engine light has been on for about a year, I have been told by both the dealerships here in Memphis/Collierville that as long as the light is an orange color there is nothing to worry about but it has been on consistently for about a year. I had a Diagnostic test done on [XXX] by Dr. Benz Affordable Mercedes Benz care and it was revealed that ME control module, oxygen sensor, engine wiring harness has oil intrusion all throughout. I would hate to attempt to drive my vehicle and all of a sudden it is severely damaged because of this. I feel this may be a very costly expense and would like some assistance in taking care of this matter. I love my car and have not had any problems, and hope to have it several years more. I only have 116,038 miles on this 2012 vehicle that I purchased in 2015 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The rear subframe / axle carrier on vehicle failed. Rear subframe / axle carrier had significant corrosion / rot and large rust holes present. Also, the rear suspension parts & air shocks were seized / corroded to the rear subframe. Dealer advised vehicle was unsafe to drive.

I have video available that shows significant premature corrosion of the rear subframe and brake line. The safety of others will be put at risk at the time of failure. Failed subframes can lead to loss of control. This problem has been identified and the part inspected by a Mercedes dealership. There are no warning lamps or messages to alert the driver that failure is imminent. This was discovered in the process of the car being serviced for an unrelated emissions recall. Many Mercedes owners report having severe rear subframe and brake line corrosion issues on message boards. Some reported their cars unexpectedly sway and drift to one side while breaking. In multiple European countries, Mercedes is apparently aware of the problem and is voluntarily replacing the rear subframe for free. However, in the USA, Mercedes is quoting their customers approximately 6,000 to 7,000 to rectify the issue. Without NHTSAs intervention, dealer service departments will continue to profit from the failure of this critical component. Customers unprepared to pay for such a significant repair will defer maintenance until they can afford to address the matter. Some of these cars will be dumped at trade in and passed on to unsuspecting consumers. Those consumers may be your friends and loved ones. We need government to step in and protect the public interest. “If not you, then who? If not now, when?”

Camshaft sensor leaking oil into engine harness and ecu. Misfire

Camshaft sensor leaking into ecu and engine harness. Causing damage and contamination Known defect in prior years model but hasn't with the 2012 model..

Totally puzzled.. Intermittent misfire from.exhaust. not a very loud backfire sound. Sounds like a fart or gurgle from exhaust only when I start the car sometimes. No check engine light No lights on the dash Car runs fine, accelerates normal, no ticking, vibrating or shaking..no rough idle Put on a code reader No codes pulled Only misfires after being driven engine turned off and back on. Starts fine. Went to several mechanics and unable to assess misfire due to it being random Spark plugs and coils changed Air filter and cabin filter changed No leaks in the exhaust Looking for answers
