general problems of the 2014 Mercedes Benz E350 - part 2

Vehicle is 9 years old, with 73000 miles. Dealer service has advised that the rear subframe and brake lines are rusting and need to be replaced as a safety issue. Cost quoted was $8800. Mercedes agreed to pick up the cost of the parts and the dealer offered to split the installation cost, bringing my total down to $3150. On-line research reveals this is a common problem across several product lines and has been an issue for 20+ years. Failure at this point could lead to uncontrolled movement of the the rear suspension structure, the rear suspension members, wheels, and electronic sensors in the abs causing loss of control and brake failure.

Was driving the car with my family close to home and the brake light came on. I drove home and noticed break fluid under the car. I took the car to leober mercedes in skokie IL where I purchased the car and where I sometimes had it serviced. They told me my rear brake lining was corroded and it would be close to $4k to repair. I had it repaired but new that had to be a product defect since that just doesn’t happen as part of normal wear and tear and especially not to a car that has 57773 miles and hasn’t been flooded and that was regularly serviced. I’ve also found out that others have had the same issue with their mercedes.

Brake line failed the hard line. Lost my brakes . Mercedez ralley motors of roslyn n. Y said that it was normal rust . There was no warning before the failure.

Brake booster starting to squel and squeak. Brakes not feeling as firm driver seat leather was torn at stitching.

10/14/21 was cautioned that the rear brake lines and caliper hoses were very corroded. Mileage 43,185 10/19/22 cautioned about rear brake lines. Mileage 48,459 12/11/23 rear brake lines replacement cost $4497. Repair not done at that time. Mileage 53,375. Again cautioned. 10/30/24 service date- was informed that the rear subframe was corroded and would be replaced by mercedes-benz. I have photos from the dealer. There are holes in the rear subframe. The brake lines could be replaced at the same time at a cost of $2820 due to the fact it is in same area. Mileage 58,597 I asked m-b customer service to cover the rear brake lines as the under coating was not sufficient to protect the rear subframe and brake lines. They rejected my claim. I was told others have also tried to get m-b to cover this cost and were rejected. My vehicle has very few miles for its age. I have never had to replace rear brake lines in the 40 years I have owned a Mercedes Benz vehicle. I believe that they have not adequately protected the undercarriage from weather. The rear subframe is my evidence. At some point these brake lines could fail. They will be replaced. I want the manufacturer to cover the cost of the brake lines when the rear subframe is replaced. Please advise.

Distronic was in use, and failed. Abs locke up, causing me to skid into another vehicle.

Rotors fail after vehicle was idle for 12 weeks. Rust caused the rotors to make brakes pulsate. Dealer would not honor warranty, and maintained that the rotors were wear and tear items. But shop foreman informed me that this has been a problem for the last ten years and that they replace rotors of vehicles on the lot which have sat for several weeks in the winter. Upon my inspection of the rotors it was clear to see that the rust did indeed cause the surface of the rotors to score and deform.

Was driving on 95n around 65 mph when vehicle loses power !!! I was in the left hand lane and traffic was flowing. It was by the grace of god that I made it to the right shoulder without causing a major accident for myself as well as for other vehicles. The engine light came on and the anti skid and anti skid off lights came on also it said consult owners manual. The vehicle is brand new and I never want to drive it again!!!. After I stopped I cut the vehicle off and restarted the vehicle to try and get home. On the way home it did it three more times. I could have killed myself and my daughter also who ever else was on the road. Once I got home I was really pissed after reading about all the other benz owners that had the exact same problem. This is terrible for a brand new mercedes !!!!!!.

The vehicle was serviced on 11/27/13. On 12/2/13 pulling away from a stop sign there was a loud pop and sudden drop to the car. After getting out of the vehicle and looking to see what had happened we noticed that the wheel had detached from the car. Police were notified right away because the vehicle was still in the road. Mercedes benz embrace was notified directly afterwards and informed as to what had happened. The tow truck driver had to take a bolt out of each remaining wheel to re-attach the one that came off to load the vehicle onto the flat bed. Four lug bolts were missing. We did find a piece of a broken bolt laying on the ground not far from the car. The car was towed to the Mercedes Benz in memphis. I think this is a serious defect and should be thoroughly investigated to save the life of other drivers, had this happened to me on the interstate were I would have been driving at the speed of 70 mph all of us sitting in the car would have been dead and no one would have been able to find the cause. I hope you will take immediate action. Thanks.
