Hi, I have had my 2018 4/4 a year and all is well, I have gelled with it and covered 9000 miles. But just something I have noticed, the rear of the car is slightly lower than the front, if measured from the wing or sill behind the front wheel to the ground its 1/2" higher than taking the same measurement from just in front of the rear wheel. I'm sure its nothing but is the sill(running board) underside normally parallel to the ground? I shall measure it again on the flat with 1/2 a tank of petrol rather than full as it is now.
