On certain vehicles, the tow hitch harness control module software could cause the instrument cluster to reboot while driving. If this happens, you may not be able to see certain information about the vehicle, including the speedometer, warnings, and tell-tales.
Warnings, tell-tales and gauges that don't display could increase the risk of a crash.
Kia will notify owners by mail and advise you to take your vehicle to a dealership to inspect and, if necessary, replace the tow hitch harness control module.
