No automaker is having fun dealing with semiconductor chips and printed circuit boards, but Hyundai and Kia are having a particularly difficult time. The two brands recently had to recall four models for two problems with the printed circuit boards in their official towbar accessory. Now a potential problem with the circuit board that controls the oil pump in the eight-speed dual-clutch transmission used by Hyundai and Kia is forcing recalls of eight models. Potentially inadequate soldering work could allow a component on the board to come loose, thus causing the pump to malfunction. If so, warning lights, a beep and the “stop safely immediately” directive alert the driver and the vehicle enters failsafe mode to prevent further damage. The biggest problem is that the transmission control unit (TCU) gives the driver between 20 and 30 seconds to park in a safe place before disengaging the transmission clutches. Without clutch operation, the car does not move.
The vehicles concerned are:
There are 53,142 Hyundai in the United States in the total recall population, another 8,719 in Canada. There are 69,038 Kia involved, 65,612 of those Sorentos. Car manufacturers believe that no more than one percent of the total population is affected by the problem.
The solution is a trip to the dealer for a drivetrain inspection and software update. Dealers will replace faulty shifters free of charge and upload new TCU programming that extends failsafe operation to give drivers more time to get to a safe haven.
The owner’s notification letters will be sent by post by the beginning of December. Owners who don’t want to wait that long can contact Hyundai Customer Service at 855-371-9460 and mention the internal callback number 236, or contact Kia Customer Service at 800-333-4542 and mention the recall number SC250. They can also contact the National Highway Traffic Safety Administration (NHTSA) Vehicle Safety Hotline at 888-327-4236 (TTY 800-424-9153). The NHTSA campaign number for the Hyundai edition is 22V746000, the campaign number for the Kia recall is 22V760000.
