Rear Suspension Coil Springs problems of the 2018 Volkswagen Atlas

The rear of the vehicle dropped 5" to 6" after driving approx. 400miles. The driver side wheel well is 1. 5" from the tire & the passenger side is 2" away. The wheel well has a "warped" wheel well. The springs seems to be locked or dropped. Looking at the Atlas in profile the rear is lower than the front. Before the trip I was able to walk under the tailgate when open without hitting my head & now the rear of the vehicle is low, I have to bend over to prevent hitting my head. Please note, I am not a trained service tech. I am an owner; I am doing a process of elimination for why the rear is lower. I searched google & found that in February Volkswagen recalls 6,322 vehicles to repair faulty rear springs. But my vehicle was not listed on the recall. I am out of state from my purchased dealer & the local dealer does not have a recall listed as "faulty rear springs" for my VIN. We have 20� black rims / wheels on the vehicle. The photo shows the factory installed trailer hitch receiver at 13" & according to vw website it should 19". (Feb. 18, 2019 - Volkswagen has recalled 6,000 vehicles to repair possible faulty rear springs. According to the automaker, it is possible that a rear coil spring might shatter causing handling problems and the possibility for an accident. ).
