I have a 2015 Cadenza and in 2019 with under 60k miles I took it into the shop due to a noise coming from the front driver's side. They came out and told me that the coil spring was cracked and that I must've hit something hard to do that. I looked at him in disbelief because that was the ONLY thing wrong. There was no damage to any other part of the suspension. Of course they dismissed the idea of any warranty covering it, so I paid to fix it. Moving forward to 2021 (just under 80k miles), I hear a noise coming from the passenger side, take it to the shop and once again, broken coil spring. The mechanic was dumbfounded because that was, once again, the only damage found. Well, this time I got both springs replaced and with the mileage on the car, the struts and lower control arms were replaced as well. I've contacted Kia customer service to lodge a complaint because this is their own parts failing (only place they could get factory spec springs was through Kia. I guess we shall see how this turns out.
