CUSTOMER CONCERN The vehicle has a no-crank, no-start condition with a Service Hybrid System message and DTC P0BBD after an earlier stall. CAUSE The BECM reported insufficient drive-motor battery voltage, and the confirmed repair identified the high-voltage battery assembly as failed. CORRECTION Remove and replace the drive-motor high-voltage battery assembly, clear DTC P0BBD, and verify starting and hybrid-system operation.

CUSTOMER CONCERN Power-steering assist is unavailable and the PSCM stores DTC C056E-4B. CAUSE The confirmed repair identified an invalid Power Steering Control Module calibration rather than a failed steering motor or power circuit. CORRECTION Calibrate the Power Steering Control Module and perform the steering position and torque-sensor calibration, then clear C056E-4B and verify steering assist.

CUSTOMER CONCERN The engine has a repeat oil leak, the dipstick is pushed out of its tube, and moisture is present in the fresh-air tube. CAUSE Inspection confirmed a leaking valley-pan gasket and an oil-pressure-sensor leak rather than an isolated rear-main-seal failure. CORRECTION Remove and replace the valley-pan gasket and leaking oil-pressure sensor, clean the crankcase-ventilation passages, and verify the oil leak is eliminated.

CUSTOMER CONCERN The engine will not start and the Service Hybrid System message is displayed after repeated restart attempts. Battery Energy Control Module DTC P0BBD is stored. CAUSE Inspection confirmed water-contaminated fuel had entered the fuel system, and repeated attempts to start the gasoline engine discharged the high-voltage battery. CORRECTION Remove the contaminated fuel, clean or replace the affected fuel-system components, perform the required engine-oil and ind

CUSTOMER CONCERN Check-engine light is on with DTC P0430, although the engine otherwise runs normally. CAUSE Fuel-trim, misfire, coolant-consumption, and catalyst testing confirmed the bank 2 catalytic converter had failed. CORRECTION Remove and replace the failed bank 2 catalytic converter.

CUSTOMER CONCERN The oil-pressure warning light comes on while the engine is running, and DTC P0521 is stored. CAUSE Pressure comparison and circuit checks confirmed a failed engine oil-pressure sending switch. CORRECTION Remove and replace the engine oil-pressure sending switch.

CUSTOMER CONCERN The Reduced Engine Power and Traction Off messages are displayed, and DTC P2135 is stored. CAUSE Throttle-position signal testing and the applicable service coverage confirmed a failed throttle-position sensor cover assembly. CORRECTION Remove and replace the throttle-position sensor cover, then program the Engine Control Module with the applicable calibration.

CUSTOMER CONCERN Customer states the vehicle has low power. DTCs P061B and P0AC4 are stored. CAUSE Hybrid-system DTC and battery-pack testing confirmed deterioration inside the high-voltage hybrid battery pack. CORRECTION Remove and replace high-voltage hybrid battery pack. Perform required module setup and clear hybrid-system DTCs.

CUSTOMER CONCERN Customer states the engine stalls at stops instead of completing a normal Auto Stop. Multiple ECM, HPCM and TCM communication DTCs are stored. CAUSE Inspection following bulletin 08-07-30-021H confirmed chafed high-speed CAN wiring causing intermittent module communication loss. CORRECTION Repair chafed high-speed CAN wiring and protect harness from repeat contact. Clear communication DTCs and verify normal Auto Stop operation.

CUSTOMER CONCERN Customer states the engine intermittently stalls during Auto Start, often will not restart and displays Service Hybrid System. DTC P0BBD is stored. CAUSE Battery-module voltage testing and the applicable battery service bulletin confirmed an internal hybrid battery-pack failure. CORRECTION Remove and replace hybrid battery-pack assembly. Perform sequential EBCM, HCP, ECM, TCM and BECM programming, clear DTCs and verify Auto Start operation.
