2016 MERCEDES-BENZ C300 Complaints

Electronic power steering failed. The electronic power steering on this vehicle has failed several times, making it almost impossible to steer. When this occurs, steering requires a tremendous amount of force and puts the vehicle and driver at enormous risk of an accident.

Electric power steering lost power and failed while driving on drive way. The steering became very difficult to turn and the car became very hard to control if not impossible. If it had failed while on the road with other cars, especially while turning, the car could be in a crash with serious accident that could have injured me and others. The problem was reproduced by the dealer. The dealer examined the car and steering components and has confirmed that the electric power steering rack failed. There was a recall done (17V243000) some time ago, however, my VIN is not included in the recall. The problem that my car is having is exactly the same as is described in this recall, 17V243000. It seems that more cars are having this same issue.

I took my car for service "B" at the dealership. They told me the rear subframe is rusting and there is a hole forming already. Apparently, this is a known problem that Mercedes Benz provided warranty extension up to 20 years with unlimited mileage. However, they stopped at 2015 models. Mine was bought from the same dealership in October 2015, but it is a 2016 model, but actually has the exact same problem earlier models have and they cover with their voluntary extended warranty. I am told to replace it, it will cost at least $4600. They are refusing to cover it under warranty because I my car is at around 60,000. The car did not even reach 100K and well maintained, but has rusted frame already that can be a serious safety hazard according to Mercedes Benz associate.

Power Train System - P052E Positive Crankcase Ventilation Regulator Valve Indicates a fault in the Positive Crankcase Ventilation Regulator Valve. I repaired my car for the same issue in 2019 January and it failed again in 2024 January. It costs $2000 to repair and it has a warranty of two. It failed after 3 years. Same issue is occurring in Mercedes C300 and GLC 300 and multiple times. But company isnt taking any responsibility to fix the issue or at least extend the warranty. 1.
