The official notice
Defect
On certain vehicles, a software problem could cause the instrument panel cluster to reboot while driving. As a result, you may not be able to see certain information about the vehicle, including the speedometer, fuel gauge, tire pressure monitoring system (TPMS), warning lights and malfunction tell-tales. Note : For the Santa Fe model, this recall only affects the hybrid model. For the Palisade model, both gas and hybrid models are affected. For the Tucson model, gas, hybrid and plug-in hybrid (PHEV) models are affected.
Safety Risk
Warnings, tell-tales and gauges that don't display could increase the risk of a crash.
Remedy
Hyundai will notify owners in writing and send a wireless over-the-air software update to eligible vehicles to update the instrument panel cluster software. Alternatively, you may schedule an appointment to have the update performed at a Hyundai dealership.
