Hyundai and Kia recall vehicles due to charging unit problems

Hyundai and Kia are recalling a combined 147,110 vehicles — including the electric vehicles Ioniq and the EV6 —because a part inside the cars may stop charging their batteries, federal auto safety regulators said. 

The recalled Hyundai and Kia vehicles have what the automakers call an "integrated charging control unit" — which is responsible for charging the car's 12-volt backup battery. 

But the charging unit may not operate correctly and eventually cause a driver to lose power while operating the car. Driving during a potential loss of power increases the risk of someone getting into an accident, Hyundai and Kia said in recall documents submitted to the National Highway Traffic Safety Administration.
