On September 10, 2025, Kia responded to NHTSAâs IR: Kia reported the change in temperature from âcoldâ to âwarmâ engine testing was done to increase accuracy.

Should you keep driving it?

This page can't tell you that. 0 of 25 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
