When accelerating from a stop, the car abruptly lost power and it felt like the engine was going to stall out completely, but then the car started accelerating again. This happened three time today. In two cases I was needing to accelerate briskly as I was either crossing, or entering onto, a busy street with fast traffic. In two cases (in both cases I was making a right turn from a stop) the red exclamation point warning sign appeared briefly on the dash board upper screen. On the third occasion (I was accelerating straight ahead from a stop), a red written message appeared on the center dash board screen, but it disappeared before I could read it.
