“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.”

“We took our car into the local Mercedes Benz Dealership at Ft. Washington, PA for a routine service and PA inspection. Our vehicle is a 2011 MB E 4 matic and has ~70K miles. We received a call stating that the rear subframe of the vehicle had failed and was not considered safe and therefore did not pass the PA state inspection. We authorized the dealership to replace the component, which was done. The dealership suggested the corrosion may be caused by salt used for removing snow. …”

“I noticed fluid on the ground under my car in the driveway. Turns out it was brake fluid, the vehicle alerted me to low brake fluid. Here was a broken brake line which appears to have been caused by the subframe being rusted out. The issue is with the rear subframe on the Mercedes’ E and C class dating from 2008 on. Mine is a 2011 E class. The subframes on these vehicles rust and rot out causing issues to the brake lines and rear suspension parts rotting / rusting out due to the subframe being compromised. …”

“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.”
