2013 Mercedes-Benz E350 Owner Complaints

Last April, during our routine oil change our mechanic pointed out that our Cam sensors were wicking oil into the harness and making its way to the ECM. This is the first we had ever heard of this issue and the repair was $2400 or so. After researching the problem we wrote to MB USA and never got any response until we filed a lawsuit in sessions court. Turns out we cant do that locally. Mercedes has never contacted us since we registered the car in 2016 and never even acknowledged us until after we filed the attempt to collect the cost of repair. THE problem is endemic and well known. MB put a poorly designed part on their 270 engines and it could have had a worse outcome had the ECM failed while my wife was driving on the interstate Please let me know what has already been done about this problem and if they are required to notify owners. MB is silent on the issue to the point I feel as though they are hiding something.

I am the owner of a 2013 Mercedes-Benz E350 and am writing to formally express my concern regarding a persistent fuel leak issue I have experienced with my vehicle. Over the past months, I have spent more than $4,000 attempting to address this problem. Repairs have included the replacement of the fuel canister and the fuel pump. Despite these efforts, the vehicle continues to leak fuel from the area near the rear right tire, both when the vehicle is in motion and when it is parked. This issue presents a significant safety risk, not only to myself but to others on the road. I am aware that there is an existing recall for the 2014 E350 model related to similar fuel leakage problems. Given the similarities in design and the nature of the defect, I strongly urge Mercedes-Benz to investigate this matter and consider extending the recall to include the 2013 E350 models as well. I believe this is a critical safety matter that warrants immediate attention to prevent any potential accidents or hazards. Thank you for your time and consideration. I look forward to your response and to a resolution that prioritizes customer safety.

Excessive corrosion on rear brake lines. I've never had to replace brake lines on car before. The cost is almost $5,000 out of pocket and I believe this due to low quality products used to manufacture the original brake lines. I believe there should be an investigation into the brake lines as there could be serious injury if they fail.

Rear subframe recall and brake lines. I am very disappointed and frustrated right now. 2013 e350 has completely corroded brake lines on an otherwise relatively rust free car. The vehicle is due to get the rear subframe replaced as part of the warranty extension. The brake lines are not covered and are 4,000 dollar additional fee to replace. I can’t get the work done anywhere else for cheaper because the rear subframe needs to be dropped in order to do the brake lines, making it cost prohibitive to have the subframe and brake lines done at different shops. Something is wrong with the brake lines they used when building this car. I’ve owned cars with 10x more rust and perfectly in tact brake lines. Frames rot away before I see brake lines this bad. They should have extended the warranty to the brake lines and I hope they do so I can get reimbursed in the future.

my car has always had an issue with the extension of the steering column. On [XXX] I had the experience of my entire steering wheel locking up totally. once I reached the repair center of Mercedes Benz I was informed that the anti theft system was no longer working. I was also informed there were several cars in the dealership with the identical same problem.. this was a very dangerous experience and has and will cost me a lot of money, as well as a safety issue as I was traveling from Atlanta to tx, 4 hrs out managed to pull off the hwy and that's where my car was towed from, leaving me in the middle of no where for 10 hrs.

There was already a recall for my rear subframe that I am now getting done due to rust corroding the metal structure. However, upon the dealers inspection the corrosion is also present on the rear brake lines which cause a safety concern and are charging $4000 to replace the brake lines aside from the warranty repair. It poses a safety hazard if the lines were to fail and have heard of others having the same issue along with rotted rear subframes.

Was informed about the extended warranty for the rusting rear sub-frame issues on this make and year. Upon speaking with the dealership and further research online the rear hard brake lines are rusted as well and not covered by Mercedes. Upon further research this a common issue and danager to my safety and others as well. Upon work required to fix rear sub-frame would make it easier job to also replace rusted brakes lines. But Mercedes does not cover that and wants to charge customers a extra 3500$ to fix something that should not be happen as well. With the sub-frame out for replacement would make sense to replace other rusted parts with the extended warranty. It's a major safety issues already with rusted sub-frame and also added rusted brakes lines. This should be investigated further into to keep everyone safe. There are lot of owners unaware of this issues that could lead to brake failure. We use our brakes to stop and most new cars should not be having this issue so early.

I don’t know why your system is stating that there is not a recall there definitely is a recall in 2023. They recalled the subframe with the extended warranty covering it because it’s been corroded and nearly dropped out of the bottom of my car. I only found out that it was so rusted and corroded by taking it to an auto mechanic because my brakes spongy and my brake light came on, so I took it in automatically to get looked at, and the mechanic said that I needed two rear brake lines, and then proceeded to tell me about the corrosion all around my subframe which needed to be replaced, which is under warranty however, my question is why is the brake lines not covered when I’ve been reading numerous complaints about the corrosion of it and yet they still have not put an extended warranty to cover that Which they should do now before a definite recall is set in place with all of the complaints coming in. I’m very upset because now Mercedes is telling me that another $3000 job. I do not have an additional $3000 for this to get fixed so I ask you, how can I get some help here?
