To your issue that you have experienced with the sonata. I too have had this system malfunction on my car not but a few days ago. Kind of concerned reading the post on the issue doesn't seem to be good. Would like to find out what happened with your situation.I have a 2020 SEL Plus. today when i tried to put car in drive I got a "gear shift malfunction" warning. It took several minutes of trying to turn car on/off and pressing drive before I could get it in drive. Anyone else have this issue?
