On about 10 occasions since I took delivery of my new 2018 Elantra Sport Automatic at the end of February, my transmission has shifted on its own accord from D(rive) to 1, 2 or 3rd gear. This has been at various MPH ranging from 10 to 70. When I come to a stop it goes back to D(rive).

I can't reproduce it, and the conditions when it happens are varied. The dealer checked for computer error codes, but none were identified. Has anyone else experienced this?

you wont see what gears you in if in auto, in manual mode it only auto shift up if you hit rpm limit.

If you hit the paddle shifters while in D it'll show the gears and then switch back to D after about a minute. That's the only thing I can think of.
