2021 Kia Sedona

The first of four tire failures (all the same DOT Number) of the OEM tires that were on the 2021 Kia Sedona when purchased in April, 2021. The first tire belt broke when on an approximate 1000 mile drive and was replaced on an emergency basis on January 24, 2024 with 16,760 miles on the vehicle. The second tire belt broke on the trip home and was replaced on an emergency basis on March 8, 2024 with 18,927. After arriving home, the tires were inspected, found to have defective belts and were replaced with a warranty adjustment by Discount Tire in Oswego with 19,191 miles. Kumho has still not honored the warranty by sending checks for the first two defective tires. (Can't find receipt from warranty replacement by Discount Tires but will continue looking. Have many photos of defective tire if desired.)
