“I was approaching an intersection about to make a left turn as the turn signal was flashing yellow and my truck just stopped accelerating. If i had taken that turn i would have got hit and most likely cause a huge pile up because the amount of traffic going through. I put my hazard lights on and tried shifting my truck into park, and then back into drive, and it would not accelerate. I had to turn my truck off and on a few times for it to accelerate.
