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.

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.

Rusted brake lines after Sunframe rust. All E350 models are experiencing this issue with the rear brake lines and the dealership is charging upwards of $4300 to replace even when the subframe is already removed from the vehicle due to subframe issues

Brake line corrosion and rear subframe corrosion

Rear brake lines rusted and replaced. Had taken to dealer to replace rusted rear subframe for which Mercedes had covered under an extended warranty. During this repair dealer noted that the brake lines were rusted and should be replaced. This was not covered by Mercedes.

Rear brake line failure, loss of brake fluid, caused loss of braking

NHTSA ODI 11601763

The brake fluid lines rusted. The front line, due to the rusted hole, leaked brake fluid to the point that the car had little to no braking ability. In addition, the computer warning did not activate. The car was taken to the dealer, where they verified that the computer warning did not activate, and that the brake fluid had bleed out causing the vehicle to have no brakes. This is a dangerous situation! The car is a little over 10 years old, has about 54,000 miles. Had I been on the highway and tried to make a hard stop, I could have had a terrible accident. The dealer now has the car for repairs, but there are many other E350 that have posted online that they have had an identical situation where the brake fluid lines have rusted out! This leaves the driver, without any warning, to be put in a life threating situation!

Complete system brake failure. Brake lines are completely corroded.

My break’s completely failed with no warning signs while I was driving on the freeway. About 6 months ago my driver side break lines were rusted and had a leak in the line causing my brakes to fail. The line was replaced with nickel copper lines and on Sunday when driving the car at 40 mph for ten minutes and the breaks began to fail. As I pulled over to get to safety after parking the car the check BREAK fluid level warning came on the dashboard. I got the car towed to my house and the following morning I added brake fluid the following and realized it’s leaking near the rear brake line on the driver side. But why and how?

Corrosion in rear brake line. Brought car for warranty service for rear subframe corrosion at a Mercedes dealership, and the service advisor noted corrosion in rear brake line. Researched online and another complaint for same issue was denied in October 14, 2020 (85 FR 65136). A website [XXX] lists anecdotal evidence of complaints following the initial investigation. Since it is the same problem effecting same model year as the subframe, further investigation seems warranted. Before being brought in, the car fishtailed, which could have been due to the defective subframe. No lights or warnings.

On July 5, 2023, I was driving my 2013 Mercedes E350, when a red text warning appeared in the speedometer display: "BRAKE Check Brake Fluid Level". I immediately took my car to the dealer's repair shop at Contemporary Motor Cars in Little Silver, NJ. Their mechanic inspected and found that both rear brake lines were leaking and needed to be replaced. I requested that they do the necessary repairs. The total cost I paid was $2309.18. My car has 106,352 miles driven. In my 50+ years of driving, I have never experienced such a serious failure in the many cars I previously owned. Subsequently I did some research and found the the NHTSA denied a Defect Petition DP20-004 for a complaint that had been filed by Mr. Surjit Singh for the same failure in his 2013 Mercedes E350. I also found many other on-line complaints about leaking rear brakes lines in 2013 model Mercedes E350 cars. I recommend the NHTSA re-investigate this serious car defect.

I have a pre owned 2013 Mercedes Benz E-Class 4 Matic. This car runs beautifully and has been not missed a service appt since I took ownership in 2016. September 2022, the cars break light came on, took it to Mercedes Benz Natick, Ma and they states the cars brake lines were heavily corroded and was unsafe to drive. It was leaking brake fluid as well. Upon doing extensive research it seems to be a trend with this years model due to the material that Mercedes Benz used instead of the brake lines used in previous models that had no issues at all. It is a safety issue and they are endangering lives due to the poor quality material that they used for the brake lines.

We have been told by our Mercedes Auto Repair shop and subsequently confirmed by two additional auto repair shops, that our rear sub frame has deteriorated and that the steel brakes lines are also rusting creating a very dangerous situation. We were warned to drive straight home and not to drive it again. We have also been told that this is a "known" problem with Mercedes C and E class cars and that the sub frame deteriorates from the inside out and has nothing to do with salt on the roads or snow or ice. Had we not brought it in for the usual oil change and check up we could have been killed. We understand that there are recalls in the UK, Canada, Ireland, and other countries but not in the US. The repair is $7,000.00+ and the wait for the part is approximately 6 months. Why is there no recall in the US? We have read numerous reports on the Menz World Forum with the same issue. I would like to file a complaint as someone could be killed and Mercedes is not addressing this hazardous issue. Does someone have to die before it is recalled?
