WHILE DRIVING ON A LOCAL STREET, I NOTICED THAT BRAKES HAD STOPPED WORKING. AFTER INVESTIGATION, I NOTICED THAT A CORRODED BRAKE LINE WAS LEAKING BRAKE FLUID. I HAD CONTACTED MERCEDES BENZ CUSTOMER SERVICE. I WAS TOLD TO CONTACT A DEALER, WHO CONFIRMED THAT ALL BRAKE LINES ARE CORRODING IN THE AREA CLOSE TO THE ENGINE COMPARTMENT. I WAS TOLD THAT THIS IS NOT A SAFETY ISSUE SUBJECT TO A RECALL. I WAS FURTHER TOLD THAT IT IS NORMAL FOR BRAKE LINES TO CORRODE AND LEAK. I HAVE NOT NOTICED CORROSION ON ANY OTHER PART OF THE CAR, EXCEPT THE BRAKE LINES. *TR
