My 2016 has developed a nasty habit of dropping the front end down to the stops. Been back 3 times to the dealer. Twice with the car still in the extreme low-rider mode (towed both times) and once after it "fixed" itself. I've contacted Hyundai, opened a case #, in regards to the problem and that the dealer is clueless. Dealer has the car now (been a week so far this time) and can't get new front struts until sometime in Jan. 2019 due backordered. I doubt that the struts are the problem and am thinking it's more of an electronics issue since the car works for days/weeks on end and then does it's thing at random. Once down the car does give dashboard warnings and codes are stored in the computer. Also, the high/normal switch function doesn't always raise the car even when the car is maintaining normal road height and otherwise working.
