I bought this car new on 1/16/14. on 2/19/14 the engine light came on and the engine lost power. i took it to the dealer and they replaced a sensor assembly. on 3/18/14 the same thing happened and the car lost power. the mileage was about 1,500.. now i am being told that there is a problem that the engineers at gm are looking into but no fix is in sight.. the first two times i lost power i was in town but if this happened on the highway it could be a real problem. i feel gm has a major problem and they do not want to be honest. i am being told nothing other then they are working on the problem. *tr
