NHTSA Complaint #11713901 — 2024 KIA EV9

The contact owns a 2024 Kia EV9. The contact stated that while driving approximately 20 MPH, there was an abnormal slapping sound coming from the rear passenger’s side of the vehicle. While observing the tires, the contact became aware that the rear tires were bald, and the steel belts were coming from the inside of the tires. The contact used Fix a Flat inside the tires and was able to drive the vehicle to the residence. The following day, the vehicle was towed to the dealer, and the dealer that it was a known issue with the original tires on the vehicle. The contact was informed that the failure was caused by the battery, causing the vehicle to be too heavy for the vehicle. The inclination, tilt, or angle of suspension components with the shocks, struts, or control arms, known as the CANT, caused the tires to tilt outward approximately 2 or more inches. The dealer diagnosed that the suspension could have failed. The cant, suspension, and tires were replaced, and the wheels were aligned. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was 12,668.
