Corroded brake lines. This is a well known issue for many Ml350s built during this time period. This car was built with steel brake lines that easily corrode and present a serious safety issue.

Mercedes refuses to correct this under warranty.

4 Service Brakes problem

Failure Date: 08/15/2024

I was driving locally and when I put on the brakes for a car exiting a street. Immediately my car sensor went on and my car brakes started to fail. It was a very scary situation. This is a known problem with mercedes. Mercedes has a recall for the brake booster but will not fix the booster without the brake like being fixed. I have reached out to foreign motor car dealerships and this issue with the brake line is a known problem and a safety issue but mercedes is not taking responsibility for this issue that can kill someone for their parts that are corroding and rotting. Mercedes too years to take responsibility for the brake booster which can kill people and now they are not taking responsibility for their brake line issues that again can injure and kill people.

Failure Date: 03/08/2023

Brakes died in may, 2022 and it took the dealer to September to inspect as it was part of recall. They told me they had to order the part so I called every 3 weeks to see if it came in. In December they said they need to inspect to see if it is covered. Again they inspected and said yes it is and we need to order the part (this is crown eurocar mercedes in st petersburg). At the same time I called mercedes USA (they gave me a case number 2-37306691522). They picked up the car in December and since then it has been the same run around. They are not attempting to fix the problem. I am begging your department to help in this matter.
