Engine Stall problems of the 2014 Mercedes Benz C250

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.
