Most recent owner complaints, unedited.
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.
Rear subframe rotted / corroded. Rear brake lines rotted and rear springs broken from corrosion . Mercedes refuses to address the issues under warranty except the subframe issue . Almost crashed on i-84 with child in vehicle due to rear control arm being rotted from subframe .

Rear subframe snapped under hard braking on the highway and caused my to veer into leftmost lane. It was terrifying and a severe hazard on the highway. Had vehicle towed to my house. I lifted and inspected my car and found the rear subframe was rusted and a crack straight through. The rear brake lines were also severely corroded and are very close to failing. Front brake lines have no corrosion. It seems that the rear subframe and rear brake lines have the same anti rust coating which are clearly not sufficient.

The vehicle was then towed to the dealer, where it was determined that the subframe and rear driver's side control arm needed to be replaced.

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 bang, but they did say another front end alignment was done. The vehicle still continued to pull and the steering wheel was still off center. On [XXX] I took my car to Mr. Tire for a tire rotation because the car continued to sway and jolt when going over bumps. It also made a popping noise when making a sharp turn. Then on [XXX] as I was driving, the car pulled or slid to the left. In order to keep from crashing into another vehicle, I pulled the wheel right causing me to run over the medium and almost crashing into a building. I was extremely shook up and in disbelief. Has this type of thing ever happened to anyone else before after the subframe was replaced? INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Driving on a highway approximately 65 MPH. Had to break fairly hard due to unexpected traffic. When breaking, my car fishtailed and I thought I was going to hit the vehicle in front of me. I immediately took my car to my independent, Mercedes-certified repair shop. My mechanic informed me that it was a problem with the rear subframe. I then took it to Mercedes for an inspection. They confirmed that the rear subframe was rusted and needs immediate repair. I was told not to drive the vehicle as it is extremely unsafe. Mercedes is aware of this problem. There was a class action lawsuit filed in February of 2023. Mercedes supposedly informed owners of the potential problem, but I was never notified. I only became aware of this dangerous subframe problem as a result of this incident.
