CUSTOMER CONCERN The vehicle was towed in with a no-start condition and DTC P0A0D stored. CAUSE Interlock testing confirmed a fault in the service safety-plug wiring. The Red interlock wire measured 5 volts with the circuit open and should be near 0 volts with the plug installed and the circuit grounded; the Black wire is the ground circuit. CORRECTION Repair the service safety-plug interlock wiring, then verify the high-voltage interlock closes and the vehicle starts.

CUSTOMER CONCERN The vehicle drives normally at lower speed, then slips badly and stops moving when the engine clutch engages. Replacing the transmission without the attached hybrid motor did not correct the concern. CAUSE Engine-clutch command, pressure, solenoid, and slip data confirmed the engine clutch was slipping when commanded locked. The clutch-pressure sensor circuits are terminal 3 Red 5-volt supply, terminal 1 Black ground, and terminal 2 Blue signal. Engine-clutch

CUSTOMER CONCERN A clicking or thudding noise is heard from the steering column while turning the steering wheel, even after the related recall work was completed. CAUSE Inspection under Hyundai bulletin 14-ST-002-1 confirmed the flexible rubber coupling inside the motor-driven power-steering assembly was worn. CORRECTION Remove and replace the worn steering flexible coupling, then verify quiet steering-column operation through the full turning range.

CUSTOMER CONCERN The check-engine light is on with DTC U1008 for lost communication with the radiator-shutter Active Air Flap. CAUSE Circuit testing specified approximately 2.5 volts on terminal 3 White and terminal 4 Brown C-CAN wires, battery voltage at terminal 1 Red, key-on battery voltage at terminal 2 Pink, and ground at terminal 6 Black. The confirmed failure was the Active Air Flap assembly. CORRECTION Remove and replace the Active Air Flap assembly, then verify C-CAN
