2021 Hyundai Sonata Owner Comments

Car transmission seemed to make a "clunking" sound when selecting gear from park. The car would not accelerate, the throttle seemed to be stuck and the transmission would try to downshift, but the car was not picking up speed. I eventually pulled off the road into a parking lot and turned the car off. I then restarted the car and it seemed to clear the problem, but no warning lights ever came on, and no error codes were displayed on the instrument cluster.
