Issue:
Over time, the integrated charging control unit (ICCU) could become damaged. As a result, the 12 V battery will not charge and could cause the vehicle to enter a reduced power mode. If this happens, and you continue to drive the vehicle, there could be a loss of power to the wheels.
Note: This problem will cause a warning light to turn on and warning messages to display before any loss of power.
Safety Risk:
A loss of power to the wheels could increase the risk of a crash.
Corrective Actions:
Hyundai will notify owners by mail and advise you to take your vehicle to a dealership to update the vehicle software. The dealer will also inspect and, if necessary, replace the ICCU and ICCU fuse.
