This is 2018 Mercedes Benz - C300 and it seems across this model line up and models from that year it looks like headliner particularly fabric starts to separate from the pillars in the rear. Across google there is bunch of C300 with the same issue in the same spot starting. The Car is only 5 years old and if it would be any other brand I would not be to upset about it. But this is Mercedes and they pride themselves of being a " Luxury " Vehicle where their standards should be much higher. Needles to say we contacted and went to one of the Mercedes Dealership that we got charged $226 for the inspection and Mercedes did not honored to replace the defect nor MBUSA - did not helped either. This is the problem across the model. Be AWARE and take this into consideration when thinking of purchasing this particular model year C300.

I have a 2018 C class. Purchased it with 32k mikes 12/21. April 2022 I started experiencing issues. When I put my car in drive/reverse the gears shift it-€™s self back to neutral. When I-€™m stopped at a light it will take me out of drive and shift it-€™s self in neutral. I-€™ve taken my car to the Mercedes dealer for a diagnostics paid out of pocket and they were unable to find the issue. This is a major safety concern and I would like to be contacted as it is unsafe to drive and no one seems to be able to locate the issue so it can be repaired.

The sunroof on the vehicle jams and either stays partially open or won-€™t close in the rear completely. I finally got it to close but it will not open again. I know multiple mercedes owners who have this issue with the sunroof and if the sunroof will continue to not lock properly this could be a hazard on the highway if the brackets were to break and the glass slides off.

To Whom It May Concern, I bought this certified preowned Mercedes Benz, and the recall is open. I have taken the car to the dealership, they deny me from service because its an over the air recall. The Mercedes Benz website clearly states on their letter for consumer that the remedy for this recall can be taken care at the dealership free of charge or an over the air update. Its July and I got the car back in February.

Forward collison system ($1700 option) aeb, does not work as described in mb literature or website. In my opinion, the forward collision avoidance system (aeb) in my 7 mo. Old 2018 Mercedes C300 simply does not work. I special ordered the car with the 997 pkg that includes, driver assistance, bas+, and distronic the mb manual states: 'if active brake assist detects that there is a risk of collision, you will be warned visually and acoustically. If you do not react autonomous braking can be initiated in critical situations.' And further that 'autonomous braking works at 4-124mph for moving objects and 4-31 mph for stationary objects.'
