Just bought a 2019 C300 4-matic a month ago. Love everything about it. One issue - filling up the fuel tank. Had problems two times in the row, trying to fill empty tank. Just would not take gas. First time managed to only get 1 gallon in after spewing and caughing. Second time, managed to get almost half a tank after just barely squeezing a trigger. Third fill up was OK. Last fill-up was still somewhat probelmatic, but got full tank after a lot of work just barely squeezing trigger. Will see a dealer soon, probably this week. Anyone else having these vapor locks?

Sounds like the fuel tank vent is blocked. Vapor from the incoming fuel backs up and the resulting back pressure trips the venturi on the filler nozzle. Either the tank valve is stuck/defective or is otherwise blocked.
Dealer should be able to easily get it sorted.
