As I drove the car a warning message popped in the screen stating "Malfunction" without any further details. The car kept running, apparently we'll at first. Then after car was turned off and turned on again the car accelerated by itself proving very dangerous. The day after, le message popped up again, but the car began accelerating by it self in more than three occasions, at one point almost colliding with the car in front. Also a loss of control at certain times during driving was experienced causing impared drivability compromising occupants and driver's safety. In my car was my wife and my three kids.
