Same dual clutch problem as on 2016 Hyundai Tucson. Hesitates for several seconds prior to engaging which causes significant danger in oncoming traffic. I had this same problem with the 2016 and Hyundai continued to deny any known problems. Now there is a class action lawsuit regarding this issue. I traded my 2016 in for the 2018 to get away from the problem because I was so scared. Now I have the same problem with the new car. This problem is ongoing. Also I was coasting with foot not on the pedal and not in cruise control and the rpm's shot up to 4200 then down to normal, then back up to 2200 and then back to normal. Very scary. Had clutch engaged car would have shot forward into car in front of me. Dealer has acknowledged trouble with both problems and informed me that Hyundai has switched clutch manufacturers.
