i have just purchased a santa fe 4 wd and by chance have found out a curious fault or normality in my car. If you put one of th ewheels on a pavement even just around 5 inches high, the back tailgate doe snot close properly and hits the side. This means that when the car is not level th ebodywork is moving and not steady. Is this normal as I cannot understand why the car is so flimsy.
