THE COMPONENT THAT IS MALFUCTIONING IS THE COVERTABLE TOP OF MY 2020 C300 CABRIOLET MERCESDES BENZ. THE STRINGS/CORDS THAT HOLD THE LINER OF THE COVERTABLE TOP TO THE ROOF ARE BREAKING AND IT MAKES THE COVERTIBLE TOP INOPERABLE. THERE WAS NO WARNING LAMP OR NOTICE OF THIS DEFECT. THERE IS ONLY 11595 MILES ON MY 4 YEAR OLD CAR THAT IS GARAGED. THIS OCCURRED 1 YEAR AFTER MY WARRANTY EXPIRED. THIS WOULD CAUSE THE TOP TO BE STUCK IN THE MIDDLING OF OPENING AND IT COULD NOT BE MOVED MECHANICALLY TO GET IT FULLY OPENED OR CLOSED TO THE WEATHER AND IS UNDRIVABLE.THE COST TO REPAIR IT IS ESTIMATED BY THE DEALER AT $4,000.00. tHE DEALER IS WELL AWARE OF TGIS LATENT DEFECT.

Roof panel is peeling and rattling loose. I’m afraid it will come off like the other C-300s that were recalled for their roof panel flying off.

I was driving on the highway, with no other cars near me and my panoramic sunroof exploded. It made a very loud gunshot like sound and I felt shards of glass fall on my head while driving. I had 2 other passengers In the car. One in the passenger set and one in the rear passenger side seat. They both had glass hit them in the face on head and go inside their clothes. I was extremely startled thinking that someone had shot at us or something and had to quickly take a highway exit to pull over and see what happened. Apparently this is a common thing with Mercedes as there is a class action lawsuit relating to this issue.

My wife was driving our 2020 Mercedes Benz C300 coupe near our house and the engine light came on. Then the car could not be driven over the speed of 30 miles per hour. Then it stopped and had to be towed. Fortunately, she was able to avoid being hit by other vehicles.The car only has 25219 miles. It was towed to a mechanic who performed a diagnostic test which provided a series of codes regarding the malfunction. Three codes were related to the CAMTRONIC camshaft system and its Solenoid ( Codes: P003C-53; P34AE-00; P34AD-09). Camshaft position actuators Failure codes: P34AD; P34AE. The way it happened could have resulted in damage, serious injury or death since the car suddenly stopped. The car is well maintained. We believe that there is a manufacturer's defect since this is a garaged vehicle that is well maintained and has low mileage.

Cylinder head is defective. Service advisor told me it was a known issue in which exhaust valves within cylinder head are prone to premature wear. If left unaddressed it leads to inevitable engine failure. I was quoted $12,000. My car is 2020 model year with not even 60,000. Barely even 4 years old.
