2013 Mercedes-Benz E-Class STRUCTURE,SERVICE BRAKES

I took car to dealer to have subframe repaired due to rust and the brake lines are rusted as well due to this issue and i am being charged for the brake lines.

The brake lines leaked fluid brakes started failing. Brought to a repair garage. Advised that subframe is cracked and completely corroded. Mercedes is covering the subframe but not the inferior brake lines which are failing.

Brake line corrosion and rear subframe corrosion

The contact owns a 2013 Mercedes-Benz E350. The contact stated while driving approximately 10 MPH, the brake pedal was depressed; however, the vehicle failed to respond, and the vehicle veered into another lane. Additionally, while her son was driving at high speeds, he detected a shimmy in the front end. While approaching a stop, the brake pedal was depressed; however, the vehicle was slow to respond. There were no warning lights illuminated. The vehicle was taken to the local dealer, where it was diagnosed that the rear subframe needed to be replaced. The vehicle was repaired under warranty. The manufacturer was contacted but no additional assistance was provided. The failure mileage was approximately 30,000.

I TOOK MY CAR IN FOR ITS ANNUAL SERVICE ON JANUARY 21, 2021, AND WAS TOLD THAT THE REAR SUBFRAME AND BRAKE LINES WERE SO BADLY RUSTED THAT THE CAR WAS UNSAFE TO DRIVE. THE ENTIRE SUBFRAME AND REAR LEFT AND RIGHT BRAKE LINES HAD TO BE REPLACED AT A COST OF $5,300 (MERCEDES BENZ USA GAVE ME A "GOOD WILL" DISCOUNT SO I PAID LESS THAN THAT AMOUNT). I AM THE ORIGINAL OWNER OF THIS VEHICLE AND I TAKE METICULOUS CARE OF IT. IT IS PARKED IN A GARAGE, RECEIVES EVERY RECOMMENDED MAINTENANCE CHECK AT THE SAME MECHANIC (EURO MOTORCARS BETHESDA, MD) AND HAS LOW MILEAGE FOR ITS AGE. ONLY ONE YEAR AND 7,000 MILES HAD ELAPSED BETWEEN THE CAR'S LAST SERVICE AND THE DISCOVERY OF THE CORROSION. IN OTHER WORDS, IN JUST ONE YEAR THE SUBFRAME OF THE CAR CORRODED TO THE EXTENT THAT IT WAS SO UNSAFE TO DRIVE THAT ACCORDING TO THE MECHANIC I AM LUCKY THAT I DID NOT GET INTO AN ACCIDENT. I HAVE OWNED MANY CARS THROUGHOUT MY LIFE FOR UPWARDS OF 10 YEARS AND NONE OF THEM HAVE HAD RUST CORROSION ISSUES. I HAVE TO BELIEVE THAT THERE WAS SOMETHING DEFECTIVE WITH THE MATERIALS MERCEDES BENZ USED ON THIS VEHICLE'S SUBFRAME. THE NHTSA DATABASE SHOWS THAT ANOTHER PERSON WITH THE SAME VEHICLE (WHO COINCIDENTALLY SEEMS TO HAVE PURCHASED HIS CAR AT THE SAME DEALERSHIP WHERE I PURCHASED MINE - EURO MOTORCARS BETHESDA) ALSO FILED A COMPLAINT FOR THE EXACT SAME ISSUE. HOW MANY OTHER OWNERS HAVE HAD THIS PROBLEM BUT DON'T KNOW THAT THEY CAN FILE A SAFETY COMPLAINT WITH THE NHTSA? THE MECHANIC TOOK A SHORT VIDEO OF THE CORROSION THAT I AM NOT ATTACHING TO THIS COMPLAINT; PLEASE CONTACT ME IF YOU WOULD LIKE ME TO SEND IT.
