Ac not working

[Tommyd]

My 2020 ac just suddenly stop blowing cold air. I noticed on passenger rear by tire an oily liquid discharge onto concrete. Any idea if there are known ac line leaks in that area?

My AC issue on both my old 2015 and my current 2018 has been the rear A/C lines, they both leaked by the rear passenger wheel. Can take a blue light underneath and shine up on the lines in front of the wheel, should be green if leaking. Was able to diagnose my 2018 in about 30 seconds with the blue light, knowing exactly where the 2015 had leaked.
