Steering
11/03/2025
EPS- Electric Power Steering failed while driving causing hazardous and dangerous conditions. While unable to steer the vehicle it crossed the median into oncoming traffic barely avoiding an accident and endangering my life and life of other drivers and passengers. Unlike on hydraulic systems where in case of defective pump it is still possible to steer the car, this electric steering it was impossible to control even to load the vehicle on the tow truck. Terrible technology or design, most importantly it is NOT SAFE !

Unknown Or Other

Upon purchasing my 2016 C300, I starting experiencing a right pull whenever I press on the brakes. I was very concerned as I use this vehicle to assist with dropping and pick up of my 2 grandchildren. The more I drove the car, the more unsafe especially when I attempt to bring my car to a stop. I took the car to a local mechanic and I was advice to take it to a Mercedes dealership. The mechanic also advice that it was an issue with the REAR SUB FRAME. A week later I took the car in to Mercedes as suggested and a day later I received a call and video from Mercedes that the subframe was broken and that is why I am getting that hard pull whenever I brake. Mercedes also stated that the control arm bracket is barely on and it is causing the vehicle to flex.

Picked my 5 year old Granddaughter up from camp we had a down tornado warning and we were driving home suddenly the sunroof opens it starts raining on us I hurried and pushed the button to close it when I did it made a loud crunch noise and almost shut but stayed vented and one side is higher than the other. When you try to close it or open it it does move a like but I’m scared it will break on us
