Just sharing a tidbit of information here. In the last monthly health report of my Kona, I had a message telling me that there is a "Anti-Lock Braking System problem detected" and I should set up an appointment at my earliest convenience. Nothing showed in my car and the ABS System was working fine. Today I stopped in at the dealer for them to have a look. They checked all the systems and everything was up to specs. They cleared the error and it was done and I was good to go. No cost to me.
I had a similar thing happen. Vehicle diagnostics said I "may have a condition" and should check it out. The dealer said it was a code indicating something was up with the brake module. They cleared it and it's been fine since.
