Filed Apr 4, 2025 · Suspension · FL

This vehicle, with 115,000 miles has been discovered to have had the brackets in the subframe for BOTH rear lateral arms rust through and are broken causing a $5,000 repair estimate. The mechanic who found this (42 years as a mechanic) said he has never seen anything like it. This is a car where I had to replace the transmission at 49,000 miles and the control unit at 62,000 miles (over $13,000 in repairs). I saw through AI search that this problem has been reported many times but has not prompted an investigation. This issue should NEVER happen and is a MAJOR SAFETY threat.

Driving on interstate, hit the brakes and noticed the car was swaying hard to the left. After that it progressively got worse. When hitting even the smallest bump or braking I heard a metal on metal ‘thunk’ sound. My daughters were in the car and it was frightening. Upon further inspection by a Mercedes mechanic, the secondary frame had rusted and snapped into. After reading forums online I found it’s very common. They rust from the inside out. There was absolutely NO previous warning.

While driving at approximately 55mph on the highway, I was required to brake for a merging vehicle who decided to make a lane change at the last second. I used my breaks, and my car did not break correctly. Instead, the car pulled the the right and locked up, it felt as though I had lost control of the car. When I went to my mechanic, I thought it was a break issue. Instead, it turns out the whole rear sub frame had rusted. When researching this issue, I found many other similar experiences. The harm that this part failure lead to was extreme. This could have been deadly. This is a safety issue that the manufacturer does not address.

Purchased vehicle May 22, 2023 at Direct Auto Sales of Orlando, Florida. Approximately two and a half weeks later the subframe broke away from the support arm rendering the vehicle in an inoperable and unsafe condition. A local mechanic said this vehicle should not have been driven. He said we could have been in an accident and suffered severe injuries or even death. Mercedes Benz of South Orlando inspected the vehicle and reported the subframe, fuel tank, front and rear axles, exhaust system, support arms, motor mounts, etc need replacing. Cost is $30,000. How could anyone fail to see damage this extensive.and not report it.

The rear subframe has prematurely rusted. It had a shear failure at speed on the highway when I applied the brakes. The rear end of the car swerved, almost causing me to crash. I did manage to decelerate the car in a controlled fashion. I did not know the rear subframe failed at the time. This was confirmed by an independent mechanic several days later. After research, it looks as though a recall has already been issued for this issue in Canada and potentially Germany. The mechanic tells me that until the issue is repaired the vehicle is unsafe to drive. My and others safety was put at risk due to the failure of vehicle control at 65 mph on a busy road. The problem was verified by an independent mechanic. No police, insurance provider, or Mercedes dealer has inspected the car/damage, only an independent mechanic. No prior indicators were given either directly or indirectly prior to failure. I did keep the part for inspection upon request.

I was on the highway traveling at 70 mph, when I noticed something was not right. I would switch lanes and notice the vehicle swaying in the rear I would also brake, and notice car would sway. I didn’t have any warning signs, and have deemed my vehicle unsafe to drive. Upon further inspection, I noticed that the rear subframe has been compromised with rust, fully detaching the lower control arm from driver’s side rear. This incident could have been catastrophic. I could have easily loss control of the vehicle and death could have occurred to me and others. Perhaps the whole rear axel and wheels could have detached at high speeds
