Would appreciate knowing your outcome with this. I am having same problems but in a standard. Still, be interested in knowing what you find out.I’m having the exact same issue on mine, the dealership has replaced the transmission three times now and claimed it was fixed, went to go drive it to get tires and it won’t catch when I put it in gear. Restarted it and tried it again a few times and nothing. Came back an hour later and it catches but makes a fairly loud clank when you start to hit the gas initially.
I have the same problem, it just started ,did you ever find out what it was ?I have a 2012 Veloster. This morning when I went out to leave for work, I was able to back just out of the driveway but then I couldn't go anymore backwards or forwards. The engine would rev but no gear would engage. I shot the car off, came inside to get my daughter to see if we could push it out of the way. She said it had happened before and to let her look at it. She started it up and moved it. I figured what ever that problem was it reset itself when I turned the car off and she turned it back on. Guessing it was electrical or electronic or something.
Could this also be the GATE SHIFT ACTUATOR?
