I reported this before. I had issue with my Veloster, I have 15K miles and I noticed grinding noise when going on automatic from 1st do 2nd gear. It would happen when I would slow down, almost come to a complete stop but then accelerate at speed around 5mph. Took it to dealer today and after I took technician for a ride, he ran few updates and did few phone calls to Hyundai Tech department they agreed to change the whole transmission, it's coming in 3 days. If you have similar issues take it to them right away but also make a call to Hyundai and open the case so they see you are serious + because so many people did before me they knew the issue right away and did not have to BS me!
