I have a 2020 SX Prestige ordered in December '19 and delivered in March 2020. Both center row captain chairs have an incredibly irritating repeating vibration that occurs north of 15 mph and upwards to freeway speeds. The noise is intermittent and frequent, particularly on roads with small or large ruts, bumps, etc. Those set off the vibrations which last a couple of seconds. Sometimes the vibrations are grouped together in sets of two or three. The dealership last Spring said others had complained of this and to bring it in so they could share the complaints with the factory. When I had enough initial build quality issues to take the Telly in, they didn't know what I was talking about with the seat noise. A tech sat in the center row and thought the noise came from the transverse bar at the back of the seat base and he felt taped it. That did nothing. My son determined that the bottom of the seat cover (the fabric part not the leather) has a seam that rubs against the plastic shroud that covers all of the ugly bits of the seat cover and chair frame on both the inside and outside of the center row seats. It's clearly a design flaw, one which is slowly driving me mad. The dealer and head of service say Kia won't be interested as the rule in noise issues is that if you can't hear the noise with the radio playing at a moderate volume, it isn't a problem. That of course is the stupidest thing I've ever heard but what can I do about it? I actually did record the noise with and without the radio playing and it's clearly evident over the radio unless it's sort of loud; I've attached two files of that. Forgive Xavier Cugat and whoever is singing. Also, note that I recorded this from the front seat area so the complaint can't be made that I stuck the phone near the source of the noise. If anyone has the same issue I would love to hear about it. It is real, visible and aural and reproduceable easily all of the time.
Two other issues I've noted, when the center row seats are down, a horrible metal squeaking noise is heard when the Telluride goes over bumps. It isn't all of the time, the squeak being dependent on temperature and maybe something else? The second problem is that over several months of ownership, the rear split bench seat backs no longer line up. It's a minor problem but again, very irritating. A car with barely 7,000 miles on the odo should not have a bench seat that is anything but perfectly in line. The tech guy said, "well if you're looking for perfection you won't find it on cars that cost twice as much," to which I said that the rear seats in my Honda Odyssey with 125K on the clock still looks perfect. He even replicated the issue on a brand new Telluride in his shop and showed it to me as though seats not lining up on ANOTHER new Telluride proves that it isn't somehow a problem. Fit and finish issues are a part of car ownership, but these things seem to point to Kia being way below the Japanese in QC and frankly below Ford and GM.
