The car would seem to shift when stopping , when tires were removed the rear subframe had rusted out completely, this is a major safety issue and could cause loss of control of the vehicle. The failure is the same as what the w204s experienced but they’re being fixed at the cost of Mercedes

I was driving my car was sputtering or trying to shut off while I press the gas and I let go of the gas and it catches and stayed on. I took it to the dealership and they said they found nothing wrong. May 3rd around 12pm im driving on the freeway and as im getting on the express lane going 60 it dies and I couldn't move the steering wheel and I slammed into a guardrail. After doing research my car (vin [XXX] ) had multiple recals from the fuel pump and steering wheel and the dealership never fixed or checked any recalls before selling it to me.

Component/System Failure: The rear subframe on my 2015 Mercedes-Benz C300 failed due to severe corrosion/rusting. The subframe is available for inspection upon request. Safety Risk: This failure created a serious and immediate safety hazard. While driving at highway speeds, the structural integrity of the vehicle was compromised, I had to break and lost control of the vehicle and almost causing a crash. This also posed a danger to other drivers on the road. The condition was severe enough that I believe I narrowly avoided a major accident. Confirmation of Problem: The issue has been confirmed by a Mercedes-Benz dealership service department, who identified the subframe as rusted and structurally compromised. Inspection by Other Parties: The vehicle has been inspected by a Mercedes-Benz dealership. It has not yet been inspected by the manufacturer directly, police, or insurance representatives. Warning Signs Prior to Failure: There were no clear warning lights or dashboard messages ind...

Structure
04/20/2026
The rear of the car would begin to slip during turns and when brakes were applied. When I had the issue checked out, my mechanic said that the rear subframe has severe corrosion, rust and holes. The subframe perforation is causing instability in the rear wheels, which is a safety issue. I took the car to Mercedes for an inspection and they confirmed the holes in the sub frame,with the inspector stating that the sub frame is "about to fall off". I believe this to be a safety issue as having the wheels or subframe fall off could cause fatalities. This appears to be a manufacturing defect given recalls for the same issue in other models of the 2015 c300.
