The software update has been causing false alarms that puts engines into limp mode. The remedy is to install an overlay wiring harness to the knock sensor, that harness seems to be on back order. I would wait until they have solved the problems with the software update before having it performed. See this thread; > [@2018 Hyundai Sonata - Wiring issue](https://community.cartalk.com/t/2018-hyundai-sonata-wiring-issue/134559): > > I purchased my 2018 Sonata 5/2018. I took it in for it’s 1st check up & oil change 1/22/19 @ only 4k miles. They also did an ‘update’. As I drove home, the car was losing power. Took it back to the dealer who finally determined it needed a new major harness. Still waiting for my car 2/12/19. How bad is this? Potential future problems? Other thoughts?
