2013 Mercedes-Benz C300 Brakes Problems

“On 09-12-16 I was involved in a rear end collision (35+ MPH). I was stopped in traffic (interstate highway). My vehicle was in eco mode and the vehicle's brake hold feature was activated, the brake was fully engaged/pressed, and hold was displayed on the forward instrument cluster. While stopped, another vehicle struck my vehicle from the rear. My vehicle's neck-pro retraint system activated and the hazards activated. No air bags were deployed. However, a few seconds after the accident, the brake hold feature deactivated and my vehicle began to roll into rush hour traffic. …”

“While making a right turn into a parking lot at low speed accelerator pedal not depressed the vehicle suddenly accelerated. When brakes were depressed they failed and did not stop nor slow the vehicle. Car crashed into the building. Air bags additionally did not deploy as car hit building in corner at center of front. Minor injury to driver from seat belt restraint.”

“The rear subframe on the car is completely rusted. I get an oil change and a inspection of the car done at the dealer each year. Nobody mentioned to me that the rear subframe is rusted and is about to crack and fall apart. Was driving home from work when I suddenly had to stop and the whole car shifted to the right almost causing me to crash. Drove home and noticed a noise every time I hit the brakes. The next day took it to a mechanic and he showed me that the subframe cracked and fell apart. …”

“The Brake lines in this car rot very early in life span. This is a severe issue as no one would know unless car is brought in for repair. There is already a extended warranty for subframe rotting for my c300 and several other models and years . Both of these should be repaired due to poor manufacturing not just the subframe. Both of these issues even independently put everyone on the road at risk of potential failure. Car has been brought in for repair and has been pointed out to me both by independent party and Mercedes Benz dealership in my area. …”

“On several instances of breaking, my 2013 Mercedes Benz C300 pulls hard to the right and becomes very unstable. I assumed it was a brake problem by the way the car drove. I took it to my mechanic, who immediately identified the rear subframe had rusted so much that a control arm had broken loose from the subframe. The rear subframe acts as a foundation for the rear suspension and holds the backend together. Fortunately I was able to get this diagnosed prior to a serious accident. The car gets very unstable, especially at higher speeds, when braking. …”
