Both vehicles are at risk of rolling away unattended
A voltage drop in the shifter control unit is to blame
19,743 units are affected
The two Korean automakers have determined that a voltage fluctuation in the shifter control module can disrupt the parking pawl control signal, which could release the parking mechanism and allow the vehicle to roll away unintended when the ignition is off.
Kia received a report of an EV6 rolling away in Korea, which prompted the recall of 9,014 units of the electric Kia and 10,729 units of its Hyundai counterpart in the United States since both vehicles share the same control software for their shifter system.
Since then, four incidents of an Ioniq 5 moving unattended were also reported, all without injuries.
In the case of the EV6, the affected units were built between November 17, 2021 and April 7, 2022 while the recalled Ioniq 5 units rolled off the line between October 4, 2021 and April 26, 2022.
The fix for this problem will require dealers to update the software in the shifter control unit in order to prevent the disengagement of the parking pawl when the ignition is off.
Kia owners will be notified by mail on May 25 and Hyundai owners will receive a letter on July 10, after which they will be able to schedule a free visit to their dealership to have the problem corrected.
Until then, both automakers recommend to avoid parking on an incline if possible and to make sure to always use the parking brake when leaving the vehicle since this would prevent movement even if the parking pawl disengages.
Hyundai also said that the upcoming Genesis GV60 and G80 Electrified could also potentially be affected by the same problem, but the automaker said these vehicles will be fixed at the port of entry into the US since customer deliveries have not begun yet.
