   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…

   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…

   As I went to have my vehicle inspected, the mechanic advised me that it could not be inspected, that the car is totaled because the rear subframe is all rotted and the brackets holding the trailing arms were broke off and said that this was a common problem with these vehicles.

   On 11/24/23 Mercedes Benz had replaced my subframe which was part of a safety recall. When I arrived home after picking up my vehicle, there was a loud bang from under the vehicle. I immediately called the service department and told them about what happened and also complained that the steering wheel was cocked to the left and pulling in that direction. My service advisor John advised me to bring it back the next day which I did. They never told me what caused the loud…

   The rear subframe of my vehicle failed at the lower trailing arm mounting point (passenger side). This resulted in the car swerving to the right when I applied pressure to the brake pedal, which was worse at higher speeds. This had been getting progressively worse for a few weeks until I almost spun out on the highway while braking. The next day, I randomly got a flat tire on the rear right side while driving at 30MPH near Valley Street in Providence. There were no warning…

   The vehicle was inspected during an alignment at a dealership. The sub-frame has rotted out. The car was swaying to the side. I believe this car is dangerous to drive. The repairs are around $5000.00 dollars. There should be a recall on this Mercedes Benz E-Class 350 SUB-FRAMES. It is not safe to be on the road. The dealer is no longer around. The manufacture of this car and so many other Mercedes Benz with the ROTTEN RUSTED SUB-FRAMES should be held responsible to pay for…

    While driving down the road at 60mph, I hit the brakes to slow down. I heard a pop and thunk from the rear of the vehicle. I thought it was some boxes in the back of my car and forgot about it. I then brought my car into the dealer for an engine computer update and during the inspection they found that the passenger rear control arm mount broke away from the sub frame and that the rear brake lines were heavily rusted. They quoted a new rear subframe and brake lines. If I was…

    I brought my car into Mercedes on 9/13/2022 and was told my brake lines and subframe were rusting. It's a 2014 with only 80k miles on it. I was told I had a year before it needed to be replaced/addressed. I brought the car in again on December 12, 2022 and they said on a scale of 1-10 the subframes and brake lines were a 7 and were a safety issue. After doing some research, I am clearly not the only owner of this model dealing with this issue. This is safety issue and should…
