I had this popping up every 3 days. Tyre pressure low on 3 tyres.!!!
Turns out the valves hadn’t been changed with tyres and had perished and one was damaged. Replacement valves are available on Fleabay for a few pounds. All fixed!!!

Hi.
I just joined and thought I’d say hello.
I own a 2.0 CRDI 2016
Love it to pieces. I’ve owned Vauxhall cars for decades but the Hyundai is better built and more solid.
