I was driving and stopped car to make a turn waiting for incoming traffic to clear. When I went to accelerate after traffic cleared, the car would not go above 0.5 miles per hour. I made sure the gear had not shifted to neutral, it was on comfort drive. I changed to sports drive and the car still would not accelerate above 0.5 miles. I was now stuck in the middle of intersection with incoming traffic, so I tried to reverse. The car reversed no faster than 0.5 miles per hour. I turned car off and back on, and acceleration then worked. Very scary. I was lucky incoming traffic avoided me. Big safety hazard. Dealership so far has not been able to replicate the issue, but I read other blogs where people experienced a similar event.
