It's possible, Rafael, but it looks like the GVWR of your Atlas ranges just a bit over 6,000 lbs which I personally wouldn't be comfortable with.
So with that said, I'd recommend using a bit beefier ball mount like the B&W Tow & Stow 2-Ball Mount # BWTS10038B which has a 7.5K capacity and has 5" of drop or 5 1/2" rise depending on what you need. view full answer...

Hey Kevin, yes the EcoHitch part # 306-X7362 that you referenced does fit your 2024 Volkswagen Atltas SE.
If you want trailer wiring too the Tekonsha kit part # 118754 is the kit to go with as it has the most reliable converter box and an easy install. view full answer...
So from what I can gather, Marshall, the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118754 may have not been tested extensively to see if it'd be compatible with the 2024 Atlas.
It shows here that there is a chance that this harness possibly won't work with a 2021.5 and up Atlas, so I'm assuming that's why you're experiencing what you're experiencing.
The Curt # C67WR however has been tested and is confirmed via Curt as well to work with your 2024 Volkswagen Atlas. view full answer...
