My veloster just hit 144k miles and while I drive it will switch into sports mode on its own. Even without touching the paddle shifters, the car will stay stuck on a gear. I’ll cycle the car to neutral back to drive or sports to drive and the car will perform as if nothing ever happened. I tried driving it in sports mode and same result will occur it won’t respond to any inputs I make to down or up shift. But switching it back to drive seems to reset the issue. I even disconnected paddle shifters to see if it was sending any signals causing the issue to occur. Some drives it occurs once and other times it can occur 20times within a 30min drive. Wondering if anyone else has had this similar issue?
