CUSTOMER CONCERN The engine stalls after the vehicle sat for an extended period and DTCs P0BBD and P1A1F are stored. CAUSE The high-voltage battery state of charge fell too low during extended storage to support normal hybrid operation. CORRECTION Recharge the high-voltage battery using the scan-tool Jump Assist procedure, clear P0BBD and P1A1F, and verify starting and hybrid operation.

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 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.
