2011 BMW X3. Consumer states multiple drive train failures the consumer stated while driving, the vehicle lost power while passing another vehicle on a rural two lane highway. The vehicles computer system flashed a warning signal with a half engine icon stating: Drive moderately. Maximum drive train output not available. Have the system checked by your service center. The dealer had isolated the problem and stated a vacuum tube supplying air to the engine was crimped. However, the next weekend, the consumer experienced a similar though less extreme loss of power and the same drive train warning appeared again. The vehicle was taken to the dealer again, where they stated a possible cause was a faulty gasket, but was not sure if it would resolve the problem.
