Rear subframe corrosion and failure. Based on my queries this apparently a common issue. I am adding my report to add weight to this common issue. Vehicle is approximately 13 years old, is in good condition, and has not suffered any accidents affecting the rear subframe. Overall only minimal rust or corrosion is found during a visual inspection while on a lift. This vehicle has passed annual inspections as required by Virginia state law. The rear subframe has rusted from the inside. This corrosion was not visible from the outside, which is why it was not found in the annual inspections. Due only to this internal corrosion, the left-hand (driver) side of the rear subframe has broken loose where the rear wheel's control arm is attached. This removes one of the rear wheel's primary attachment points, making the vehicle unsafe to drive.

Per the technician: "the rear subframe is rusted out and the lateral strut arm is starting to break away". Because of this issue, the car unknowingly presented a safety risk to occupants and other drivers. A failure of the subframe or connected components could have resulted in a serious accident. Photos are attached. The vehicle is currently available for inspection upon request. There were no warning indicators to this issue. The issue was found only because the car was being serviced for brake pads. Mercedes Benz USA customer care said there was no recall or other warranty covering the issue and said the vehicle was outside their "good will assistance program". The vehicle is no longer able to be driven.

Rear subframe has rusted to the point car is no longer safe to drive. This is apparently effecting many Mercedes-?? vehicles and many unsafe cars are currently on the road.

My family has owned this vehicle since 2013 when it was purchased from the local Mercedes dealership as certified pre-owned. In the past few years, we have had to have several of the rear brake lines replaced due to rust. The last time, we were told by the mechanic that the complete rear subframe would have to be replaced due to rust. Specifically the attachment points from the subframe to the rear suspension have completely rusted through. I contacted the dealership where the car was purchased. They stated they are aware of this issue on almost all of the cars of that period but offered no solution other than a repair of $5,000. Many of the cars of that era and class have serious rust issues but Mercedes chooses to do nothing about it. This is a serious safety issue because the entire rear suspension and brakes attach to the subframe and could come loose at any point while driving. I would like this to be repaired by the manufacturer. Thank you

Hearing loud clunking noise from back. Cross member subframe. I feel like Mercedes should reimburse me.... car is only 10 years old my 2005 frame is perfect. This is a manufacturer issue with this particular year..

Mercedes dealer inspected the car. Found the rear sub-frame severely rusted at welds. He advised this was an unsafe condition and needed to be repaired soon. Service writer said this was an unsafe condition. One of the welds is almost completely failing. There is an actual safety hazard if the subframe fails completely. This condition has been occurring over a period of years. There is no recall on this type of problem. It has been well reported on many internet sites.

I was driving on the turnpike and thank god no other cars were next to me. Sometimes when I go over 50 the car tends to pull in another direction. I took it to get service a week after I bought it and got my car back 6months later. Than the accident happened. They just replaced computer chip they said. The car has never driven right since I bought it. So when the car decided to pull to the left I was pulling with all my strength to just keep the wheel straight but I had no control and spun around 5 times N landed backwards on the turnpike facing on coming traffic. I'm so upset that I never got to enjoy the vehicle it still pulls and the dealership always says its fine. The car rattles. One day I was driving N the seat I was sitting on blew up for no reason. They replace only the inside parts and never the stitching on the seat so I have a ripped seat for something that was not my fault. This call is def a lemon or should be recalled.

Another car made an illegal U-turn and caused me to T-bone on his passenger side. Front of my car hit his passenger side and dragged his car for about 10 feet. Air bags on my car did not deploy, safety system M-brace in car failed and did not call sos either. Car safety system did not detect the crash at all. Mercedes Benz did not detect a crash....updated 09-10-14 the consumer stated she received soft tissue injuries to the neck, shoulders, and back, bruised elbow, and headaches and loud ringing for 10 days caused by the crash.
