My parents just purchased a 2019 Sonata SE, 2.4L I4 F DOHC 16V Theta II GDI engine, 57,125 miles on the odometer. I'm wondering what sort of general preventative maintenance you'd recommend, as well as what NOT to do. I've seen engine/injector cleaner recommended several places, but also not recommended. A lot of contradictory information. Just looking for some clarification.

Also, I've tried to update the multimedia system, following all the steps laid out on the Hyundai website, but it doesn't recognize the USB drive. I know it's probably not necessary, but I'd love to know if anyone has any ideas.

Thanks!

[EDIT: Solved] I forgot to mention that only some songs are affected. All songs are in FLAC. However, I stumbled onto a solution: simply reconvert the affected songs into the same format. Doing so gets rid of whatever within the original file is causing the song to stop 5-second early. It's an easy fix...ish. Perhaps a bit inconvenient versus a simple pushed button or unchecked box. But it works and the reconversion is near instantaneous. So, go wild!

Songs are ending 5 to 6 seconds early. I have searched the internet for answers, but nothing seems to work. All crossfading is disabled/unchecked. I can't figure this out. I am in desperate need of help. Please help. I'm so confused and I'm going crazy.
