    The failure was when I hit the brakes hard in an emergency braking situation and the car very eratically and violently veered to the left. There was no warning and thank God there was no car coming in the left lane otherwise it would have been a broad side hit. I was doing 55 mph. We had the car inspected at a local shop and the left rear tie rod link was completely severed from the suspension sub-frame because of rust. The brake lines above the sub frame were also severely rusted and leaking. I called my closest dealer and they said the rusted frame replacement is covered under extended warrenty but not the brake lines which had the same issue, severe corrosion and a potential catostrophic failure! Mercedes Road Side Assistance was called to tow the car 70 miles to the closest shop.

    While braking from highway speeds or any other speed, the vehicle becomes unstable and pulls to the left, making it difficult to maintain control. During hard braking, the vehicle does not track straight and requires steering correction to remain in its lane, creating a significant safety hazard. To diagnose the problem, the vehicle was inspected by an independent mechanic. An alignment was performed, and the suspension and braking systems were inspected. The mechanic determined that the rear subframe has severe rust and corrosion. The rusted rear subframe is available for inspection upon request. Despite the alignment and inspection of the suspension and brakes, the unsafe braking behavior remains. There were no warning lights or messages indicating this condition before it was discovered. The problem has been reproduced multiple times under similar braking conditions. This condition puts the driver, passengers, and other motorists at risk because the vehicle can become difficult to control during braking, particularly at highway speeds or during an emergency stop. Based on the mechanic's inspection, the severely corroded rear subframe is the source of concern and should be investigated as a safety-related defect. I have also contacted Mercedes-Benz USA regarding this safety issue and requested assistance, but I have not yet received a response.

    Vehicle subframe corrosion (manufacturer extended warranty offered). Rear brake lines corroded/leaking. Vehicle leaks fuel; steel fuel line corroded. Vehicle has about 105k miles. Minor fire started when yard maintenance came in contact with fuel saturated ground where vehicle had been parked/moved out of the way just prior. With rear suspension subframe springs corroded, vehicle bottom can contact road surface while driving, scraping steel exhaust with fuel present. EXTREMELY dangerous. Local Sunbury Ohio Mercedes dealership inspected then offered subframe replacement. Stated it was leaking fuel and not hydraulic fluid we originally thought. Brake, suspension and fuel line corrosion repairs were quoted in excess of $4,000, which was a "great deal" according to them "because the subframe would already be removed and would make it much easier."
