2018 Kia Sedona Tires & Wheels Problems

AT 18,870 MILES THE LEFT FRONT TIRE OF MY 2018 KIA SEDONA SX LIMITED (ORIGINAL TO VAN KUMHO CRUGEN 235/55/R19) BEGAN TO PULL TO THE LEFT DURING HIGHWAY DRIVING. WENT TO LOCAL FIRESTONE DEALER. THEY PLACED THE TIRE ON THE RIGHT SIDE AND PULLED TO RIGHT. THEY SUGGESTED I TAKE IT TO THE KIA DEALER TO HAVE CAM BOLTS ADJUSTED. WENT TO KIA DEALER WHERE I PURCHASED THE VAN. THEY WERE NO HELP REFUSED TO DO ANYTHING THEY SAID NOTHING WRONG WITH THE TIRE. WENT BACK TO FIRESTONE AND PURCHASED A NEW KUMHO CRUGEN 235/55/R19 TIRE AND HAD IT PUT ON.UPON EXAMINING THE TIRE THEY SAID THE STEEL BELTS HAD SHIFTED. CONTACTED KIA DEALER WITH NO RESPONSE. CONTACTED KIA CORPORATE AND RECEIVED A REFUND FOR COST OF NEW TIRE. AT 39,444 MILES AGAIN THE LEFT FRONT TIRE (ORIGINAL TO VAN KUMHO CRUGEN 235/55/R19) BEGAN TO PULL SEVERELY TO THE LEFT DURING HIGHWAY DRIVING. WENT TO LOCAL FIRESTONE DEALER. THE STEEL BELTS HAD SHIFTED SEVERELY MISHAPING THE TIRE. AT THIS POINT I PURCHASED 4 NEW TIRES OF A DIFFERENT BRAND.

2 OF THE 4 KUMHO CRUGEN PREMIUM 235/60R18 TIRES ON OUR KIA SEDONA HAVE HAD TREAD SEPARATION. 21,000 MILES ON THE CAR SO FAR. CAR WAS IN MOTION AND EXPERIENCED RATTLING AND SHAKING EACH TIME.

TL* THE CONTACT OWNS A 2018 KIA SEDONA EQUIPPED WITH KUMHO CRUGEN PREMIUM TIRES, SIZE: 235/65R17 (NA). WHILE DRIVING 60 MPH, THE STEERING WHEEL SHOOK VIOLENTLY WITHOUT WARNING. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHO DIAGNOSED THAT THE TIRE TREAD SEPARATED. THE DEALER WAS CONTACTED, BUT NO FURTHER ASSISTANCE WAS OFFERED. THE TIRES WERE REPLACED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND DID NOT ASSIST. THE APPROXIMATE VEHICLE FAILURE MILEAGE WAS 19,040 AND THE TIRE FAILURE MILEAGE WAS UNKNOWN.
