I have a 2013 Elantra limited and yesterday while driving I felt a small jerk, the engine light flashed and the RPMs dropped to zero. I was driving without issue at higher speeds (50-60). Then, after a stoplight, the car was running but starting sluggishly as though stuck in a higher gear. I then switched to shiftronic (or whatever it is called) and the dash indicator showed a number 6, but it would not shift out of that gear. I parked and stopped. Turned off the car and then back on. Everything works again. The fact that the tachometer and the shifting both stopped and then recovered makes me think that it’s an electrical or computer issue. Anyone else experience this? I have over 85000 miles on it, and I am hoping it is not the beginning of a big issue.
