I HAVE EXPERIENCED RECURRENT BUT INTERMITTENT ISSUES WITH THE TRANSMISSION/ACCELERATION OF MY MERCEDES GLC 300 2017. TODAY, AFTER I WENT UP AND THEN DOWNHILL, THE CAR SLOWED DRAMATICALLY ON ITS OWN.

IN THE MEANTIME, I WAS WORRIED I WOULD BE REAR-ENDED BY TRAFFIC BEHIND ME. I HAVE HAD SIMILAR PROBLEMS IN THIS SAME SPOT (WHICH I DRIVE NEARLY DAILY) IN THE PAST, SUGGESTING GOING OVER THE HILL HAS SOMETHING TO DO…

I believe that my experience poses a significant risk to both my safety and that of other road users. In June, I encountered a distressing incident when my vehicle's steering wheel locked unexpectedly, leading to a hydroplaning incident that caused my vehicle to veer off the road. Fortunately, there were no injuries, but the situation was undeniably dangerous and alarming. My vehicle displayed a "ste…

2017 Mercedes Benz GLC 300 Coupe 27,700 miles. I was driving on MD I-95 when the Power Steering Malfunction warning light came on and I lost power steering. I got off the next exit. Steering was very difficult especially when the car slowed. The Mercedes Benz dealer is replacing the electronic steering power control unit, power steering motor and steering rack. Cost $4910. Mercedes Benz has had GLC 300 recalls for Power Steering Malfunction but not for my model year.
