There is a big hole on my 2020, all others seem to have it too, behind fuel door area if u look in the wheel well. I saw this when I first got it in september. I just drove it in some snow and all the crud they put on roads, and just washed today and rinsed that area out. Stuck my hose in the hole. Lots of dirty water came out that matched what was coming out from under rear number. So rinse that area!!! I can see things rusting in there in future.
