Hyundai and Kia are recalling their new all-electric twins, the Hyundai Ioniq 5 and Kia EV6, with their electronic parking brakes to fix a software problem that could cause them to detach while the car is stationary, increasing the risk that they could move.
“The subject’s vehicles are equipped with a shift-by-wire system that includes a shifter control unit (SCU) and a parking pole actuator motor,” Kia said in its withdrawal report to the NHTSA. “If the vehicle is stopped and a voltage fluctuates while it is parked, the command signal from the SCU to the parking pole actuator may be affected, resulting in a temporary shutdown of the parking process and potential vehicle rollways,” it said.
Every instance of the Ioniq 5 and EV6 sold in the United States (less than 20,000 cars so far) that was made before April 8 has been shipped with this Gremlin, so if you have purchased one, expect to hear from your dealer. In the meantime, brands recommend that the fault be on the back of its ugly head if possible to mitigate the risk of roll-away from parking on a slope whenever possible. Vehicles assembled after the April 8 cutoff already have new software installed.
Although both the Ioniq 5 and EV6 are capable of over-the-air (OTA) updates, brands are asking customers to bring their vehicles to solve the problem. Customers can expect to receive instructions from Hyundai or Kia sometime in late May or early June.
