engine stall under intense turbo acceleration 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.

SOLUTION: Since MB is unable to fix the car, they should be notifying ALL C250 owners of this problem and the potential associated hazards and issues. They should recall them ALL, and settle with each MB customer owning these cars. WE discussed a trade-in, and the dealer said MB would grant us a meager $2,000.00 off from the manufacturer ONLY on a NEW CAR (C300) purchase. Apparently, the 2016 C300 does not have this problem at all, so they say.

BOTTOM LINE: Though happy with the car in general, we are disgusted with this specific problem and the associated and unacceptable non-solution, not to mention the potential liability in driving the car. Our dealer is not the problem; Mercedes is - especially NOT RECALLING ALL THESE CARS!
