“The rear subframe rusted through risking the control arms from detaching from the frame. This could cause the car to be uncontrollable with the right, rear wheel and control arm from detaching from the vehicle.”
NHTSA complaint #11414126, filed 2021-04, 99,000 miles“Interior door handle on doors, specifically the driver side door, will break, and the person is unable to get out of the car. This is a very serious matter, but mercedes benz company has not put out a recall on this. Many owners have complained about this issue with no results. The owners have to pay for this out of pocket, and it is costly. I feel as if this should be a recall issue, because it poses an hazard of getting out the car if the car is in an accident or worse, catches on fire. …”
