VISIBILITY/WIPER
Since I purchased this vehicle 2.5 months ago, the windshield wipers started chattering/making noise and not working properly after about 2 days. I brought the car in and the dealership replaced the wipers. The chattering started again shortly after, then the dealership polished the windshield. It worked well for about 2-3 weeks and now the wipers are starting to streak and chatter again. I have a third appointment to have the windshield re-polished and wipers replaced, again. I have no faith this will fix the issue since its been done before. I see that this is a common issue with this brand/model.

UNKNOWN OR OTHER
My sunroof exploded while I was driving on the highway. There were no other cars around me and no overpasses. There is no explanation for the sunroof breaking. I thought someone shot out my window. It was the scariest experience I have ever had driving. If there were cars around, it might have caused a major accident.

Steering wheel keeps locking up, won’t go up and down. And sometime the steering will just come crashing down on my lap while I’m driving. Did some research and was told by Mercedes dealership that this is a common issue happening with most of their cars.

UNKNOWN OR OTHER
The manufacturer service dealer (Mercedes) has been unable to clear a VIN recall notice, even though they say it has been updated. The system still says it's recall. They have had the vehicle for almost 30 days, and have not been able to fix the issue. The recall is for a software update, and the dealer says they've done everything at Mercedes of Ft Lauderdale, and the Manufacturer, (Mercedes) says it's the dealer problem. The dealer says its Mercedes problem, and we as the customer are stuck in the middle and have no car

STEERING
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.

ENGINE
Got the MIL obd2 error code P052E - Positive Crankcase Ventilation Regulator Valve Performance. After some research this seems to be a common issue for this vehicle and other similar Mercedes Benz vehicles with the same engine. It is something that it is extremely expensive to fix (2000) and very labor intensive. I believe that Mercedes Benz should recall these vehicles and replace the Intake line due to its constant failure on many vehicles including mine.
