Engine Stall Problems of Mercedes Benz C250

Engine was stalling upon initial startup. Took to mercedes and received an estimate for $4500 for a new timing chain and cam adjusters. The car only has 46000 miles on the odometer. After searching the blogs, I find that there are hundreds of complaints about this exact issue. Why isn't there a recall or TSB on this?.

I was experiencing an engine stall when starting my vehicle and a rattling like noise coming from the engine as well in early January 2018. My engine light sensor came on about 2 days later. I took my car to mb long beach and was advised that I needed to have the camshaft adjusted which would cost me approximately $4k+. It was further explained that this issue was due to a crack in the shaft and the oil is not being properly dispersed. After further investigation on my own behalf, this is an engine manufacturer defect and there are several consumer complaints regarding this same issue. After calling mb USA several times, I finally received a call back stating, I could receive a "1-time, 10% off the total cost of the repair. If this was a consumer related vehicle repair negligence then the consumer covering the expense would be the right thing to do, but when this is a defect from the manufacturer and mb is aware of it then this expense should be one that should cover.

Random engine stall involving turbo and intercooler: we purchased this 2014 C250 with roughly 8,000 miles from nearby mb dealer. We have enjoyed the car immensely, exception this very serious "defect" with the engine. Observed on three separate occasions, this problem is very serious and could lead to potential collision while passing another vehicle, because the engine "stalls" under intense acceleration randomly, leaving only one cylinder working. With this one remaining cylinder, the car can barely be operated, shaking etc. , but can be maneuvered off the road if possible in traffic, shut off, and re-started without any after-affects. We took to the dealer twice, and both times the mb dealer admits there is a very real problem with, allegedly, the "intercooler," and that "all C250 engines have this same potential problem," and furthermore, mercedes does not currently have a solution or fix, but is working on it. Note: it's been six months since I reported my initial problem and had it recorded (filed at the dealer). The car computer does indicate the problem exists, and records each incident. Problem: mb does not have a solution currently. It is very dangerous to have the car under full acceleration in sport mode, and then the car suddenly without warning shuts down ("computer generated stall"). I was fortunate to be going very fast merging onto interstate traffic, then able to get off the road before I was rear-ended. This same scenario has occurred on two other occasions without any accident, and while motor was not even heavily stressed as the initial incident.
