Alloy wheels might be covered under the Kia warranty, but it all depends on how the damage occurred. If the damage to your alloy wheels happened due to a defect in the manufacturing process or poor workmanship, Kia would cover the damage. However, if the alloy wheels were damaged due to an accident or some other mishap on your part, another motorist, or an act of God, it would not be covered.
If you have any doubt about whether the alloy wheels are covered, take your car to the dealership. The worst thing they can do is simply deny the claim, and you’re right back where you were.
