CUSTOMER CONCERN The information display reports that hybrid-battery cooling performance is low. CAUSE The hybrid-battery cooling inlet filter beneath the right rear seat was restricted with debris. CORRECTION Clean the restricted hybrid-battery cooling inlet filter and verify the low-cooling-performance message clears.

CUSTOMER CONCERN The 12-volt auxiliary system reads 0 volts at the jump-start terminals. The vehicle starts with a jump but returns to 0 volts after the charger is disconnected. CAUSE Low auxiliary-battery voltage caused the Battery Management System to open the B+ relay, isolating the auxiliary battery from the vehicle. CORRECTION Press the auxiliary-battery reset switch, jump-start the vehicle, allow the hybrid system to recharge the auxiliary battery, and verify the vehicl

CUSTOMER CONCERN Check-engine and master-warning lights return every few days with DTC P0A80. CAUSE Battery-cooling-fan service did not prevent P0A80 from returning. Hybrid battery block monitoring and repeated exact-source confirmations identified a deteriorated high-voltage battery pack. CORRECTION Remove and replace the high-voltage battery pack, clear DTC P0A80, and verify the hybrid warning lights remain off.

CUSTOMER CONCERN The check-engine and master warning lights return with DTC P0A80 stored. CAUSE Hybrid-battery block-voltage testing confirmed deterioration inside the high-voltage battery pack. CORRECTION Remove and replace the failed high-voltage hybrid battery pack.

CUSTOMER CONCERN The hybrid warning is on, and DTC P0A80 is stored. CAUSE Battery-block voltage testing confirmed excessive voltage variation caused by deterioration inside the high-voltage battery pack. CORRECTION Remove and replace the failed high-voltage hybrid battery pack.

CUSTOMER CONCERN Battery warning light is on with DTC P1A59. CAUSE Testing confirmed a fault in the high-voltage hybrid battery assembly addressed by the applicable battery campaign. CORRECTION Perform the applicable high-voltage battery campaign repair and remove and replace the failed battery assembly as specified.

CUSTOMER CONCERN Battery warning light remains on after generator-battery assembly replacement. CAUSE Testing confirmed the replacement generator-battery assembly was faulty. CORRECTION Remove and replace the failed generator-battery assembly.

CUSTOMER CONCERN The check engine and hybrid warning lights are on with DTC P0A80 stored. CAUSE Battery-block voltage testing confirmed excessive voltage variation caused by deterioration inside the high-voltage battery pack. CORRECTION Remove and replace the high-voltage hybrid battery pack.

CUSTOMER CONCERN The check engine and IMA warning lights are on with DTC P0A7F stored. CAUSE Battery-module testing and the applicable Honda bulletin confirmed deterioration inside the high-voltage IMA battery. CORRECTION Remove and replace the high-voltage IMA battery, then update the Motor Control Module with the applicable calibration.

CUSTOMER CONCERN Customer states the engine intermittently stalls during an automatic restart and usually will not restart. The Service Hybrid System message is displayed. CAUSE Testing under GM bulletin PIT4808 confirmed an internal failure in the hybrid battery pack. CORRECTION Remove and replace hybrid battery pack. Perform sequential EBCM, HCP, ECM, TCM and BECM programming with current calibrations and verify automatic start operation.

CUSTOMER CONCERN Customer states the check-engine and master warning lights are on. DTCs P0A80 and P3193 are stored, although the engine appears to run normally. CAUSE Hybrid-battery block-voltage testing confirmed abnormal voltage variation inside the high-voltage battery pack. CORRECTION Remove and replace high-voltage battery pack. Clear hybrid-system DTCs and verify battery block voltages remain balanced.

CUSTOMER CONCERN Customer states the vehicle was parked for approximately two months and now stores DTCs P0AFB, P1A22, P1A26 and P1A29. CAUSE Campaign inspection confirmed the hybrid battery pack had failed after the extended storage period. CORRECTION Remove and replace hybrid battery pack under the applicable campaign. Clear hybrid-system DTCs and verify battery-system operation.

CUSTOMER CONCERN Customer states the IMA and check-engine lights are on. DTCs P0A7F, P1570 and P1435 are stored. CAUSE Battery-module testing and Honda TSB 09-025 confirmed deterioration inside the high-voltage IMA battery pack. CORRECTION Remove and replace high-voltage IMA battery pack. Reflash applicable IMA control software and clear DTCs.

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 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.

CUSTOMER CONCERN Customer states the master warning and check-engine lights are on. DTC P0A80 is stored. CAUSE Hybrid-battery block-voltage testing confirmed excessive voltage variation inside the high-voltage battery pack. CORRECTION Remove and replace high-voltage battery pack. Clear hybrid-system DTCs.

CUSTOMER CONCERN Customer states the check-hybrid-system warning is on and DTC P0A80 is stored. CAUSE Hybrid-battery voltage testing found more than a 0.5-volt difference between battery blocks, confirming high-voltage battery deterioration. CORRECTION Remove and replace high-voltage battery pack. Clear hybrid-system DTCs.

CUSTOMER CONCERN Customer states the malfunction indicator light is on and DTC P0A80 is stored, with no noticeable drivability complaint. CAUSE Hybrid-battery block-voltage testing confirmed an abnormal voltage difference inside the high-voltage battery pack. CORRECTION Remove and replace high-voltage battery pack. Clear hybrid-system DTCs.
