When starting up the vehicle make a terrible noise that last for 3-4 seconds before it goes away. The vehicle was verified by a mercedes technician and the diagnostics came back stating an issue with the "camshaft adjusters (internal fault)". I was told this condition will get worse and finally engine will stall and major damages will happen. Worst scenario could produce bent valves and will require a major engine overhaul with just 48,304 miles on it.
