About 20,000 of Hyundai and Kia's newest electric vehicles are being recalled. Hyundai Ioniq 5 and Kia EV6 - two impressive electric cars built on Korean OEMs' new E-GMP platform - are affected by the problem.

Specifically, the parking brake function in EVs is problematic. Voltage fluctuations can cause the shifter control unit to send a signal disengaging the parking pawl if the vehicle is parked and turned off.

Automakers in Korea have identified the problem. Hyundai reports receiving four complaints about the Ioniq 5s.

There is a recall affecting 9,014 Kia EV6s, and 10,729 Hyundai Ioniq 5s, and owners are advised to use their electronic parking brakes when parking their vehicles rather than simply turning them off and walking away. The automakers will contact the owners of affected vehicles to schedule the software fix.

Tesla also experienced a similar issue in 2017, recalling 53,400 Model S and Model X cars produced in 2016.
