When pressing the START/STOP button, the ignition may not turn off on some vehicles equipped with a gate-type AT shifter. Although the shift lever is in “P†position and the engine shuts off normally, the ignition may stay on (in accessory mode). Some customers may describe this concern as "the radio stays on" or "the radio is staying on". This concern may be caused by a worn switch unit. To eliminate this concern, the switch unit material has been changed to improve wear resistance. Modified switch units have been established as new service
parts.
