2009 Mercedes Benz C300 brakes problems

Filed Dec 21, 2024 · Brakes · ND

Went to the Mercedes dealership service department to replace the rear subframe that suddenly broke while I was driving due to extreme rust/corrosion. The dealership stated that it was being covered under the extended warranty due to the recall related to the rust/corrosion issue with the subframe. I was advised by the mechanic that the brake lines will need to be replaced due to extreme rust/corrosion in the rear at the same exact location of the rear subframe, making the vehicle very dangerous to drive because the brake lines could break at any moment and cause sudden brake failure. I was quoted a very significant amount to replace the rusted brake lines and per the dealership, it will not be covered under any extended warranty and/or recall.

Suspension Cross-Member - Mercedes-Benz (204-350-01-41) Driving regularly suddenly fill like the rear passenger side tire moved unevenly, then went to the tire shop, and when they take out the tire see how the rear frame was rusted and broken in a straight line exactly in the middle of the tire hole area. Then start to check used cars to donate that part and All of them have the same trouble in that piece, so I decided to review the frame and discover that the rust begins to damage the opposite side too, so I'm pretty sure is a component failure in metal and materials more than simple rust.

I took my vehicle to the Mercedes dealer for inspection on 7/13/22. It passed inspection, but I was told that the brake lines were very corroded and they recommended replacement before driving. Their cost to repair was $2825. I only have 54,000 miles on the vehicle. I checked on the internet to see if there were any other reported brake line issues with a 2009 Mercedes C300 and was shocked to see how many people had the same issue, some reporting that they lost brake power and had a very terrifying experience. Of course I am now afraid to drive the vehicle and not sure what my course of action will be. With the number of reported incidents, I feel that Mercedes used inferior materials that corrode readily and should have some accountability in remedying the situation. I am including some photos of the corrosion that were provided to me by the dealer.
