Bought a left over 2017 Kia Cadenza in July of 18, within first 10,000 miles car started sounding like a helicopter, took to the dealership, they drove it, thought maybe a wheel bearing, replaced that, rotated tires told me to drive for awhile and see if that changed it, went back 3 weeks later saying need to rotate tires then went back again at 17500 miles with same issue, service advisor asked me harshly 'where have you been driving this thing', I tell on the highway to and from work and daily driving, he tells me you know you can take this to any other dealership, I say no it's called loyalty, I speak with service manager, he drives the car realizing it is loud, has tires taken off another identical car, sound goes away, he talks to Kia, they decide to give me new tires, they were installed car drive fine till about another 12000 miles and noise came back, I went to a different dealership for a oil change 2 times and they never said anything about tires on their inspection, decided to go back to original dealership and they tell me tires are feathered again, I say how is that possible I have never heard of a car going through 2 sets of tires in 37000 miles, they tell me it's out of alignment again, I have never had a car need alignment before a 100000 miles now the car shakes and sways with the groves in the roads and needs a third set of tires at 37000 miles I believe there is a problem with the chassis of this car, mechanic at the dealership told me these cars are known to feather tires.

I have 4 hancook ventis S1 noble 2+ tires on my 2017 Kia Cadenza. The size and dot numbers are 245/45R18 96V dot 5mef 1A H 0217 I have a bubble, in the sidewall, in one tire that may be the result of a crack in the sidewall. The tires are very noisy particularly at low speeds and the rear tires are at 4/32" depth at 22,500 miles. Can you advise me if these tires are part of a recall? thanks for any help you can give me.

Car cupped tires around 17000 miles. Dealer blamed me for car not being aligned and not rotated frequently enough I.e. 7500 miles. I disagreed with dealer filed complaint with Kia and they made a compromise and I paid for 2 tires and Kia paid for 2 tires, different tire brand than previous tires. Car again cupped tires around 44000 miles. I heard sound immediately after tire rotation back to front. Took car to Kia sean the service manager confirmed front tires were cupped. Took car to Kia dealer a week or so later to diagnose problem. They looked at car it was within alignment specs and tire rotations done approx. Every 7500 miles. Kia dealer then told me that they believed that the tires were at fault and were going to contact tire manufacturer to replace tires. I strongly disagreed with this position and said that according to everything I have read and been told the most likely cause is a suspension problem I.e. shocks or struts. It is also not good for the car to be driven with a suspension problem and or cupped tires. Cupped tires are caused by poor contact with the road which may also be dangerous. I don't believe the problem is caused by the tires (2 sets tires different brands) so can not with a good conscious support a tire warranty claim. I believe and there is a problem with the suspension of this car not sure if it is a design problem or a problem with a certain suspension part shocks, struts or both? on 5/17/19 I filled another complaint with Kia and am currently waiting on a response. I am filling this complaint in case others are having the same problem.
