CUSTOMER CONCERN The check engine light is on with DTC P0448 stored. CAUSE Command testing of the EVAP vent valve and its external filter confirmed that the canister vent-control valve was stuck closed. CORRECTION Remove and replace the EVAP canister vent-control valve.

CUSTOMER CONCERN Customer states the check-engine light is on and engine idle speed is too high. DTC P0507 is stored. CAUSE Idle-speed testing confirmed the idle-air volume adaptation was not completing, leaving engine speed more than 200 rpm above the target value. CORRECTION Perform accelerator-pedal released-position learning, throttle-valve closed-position learning and idle-air volume learning. Clear DTC P0507 and verify normal idle speed.

CUSTOMER CONCERN Customer states the vehicle does not power up or start when the push-button ignition switch is pressed, although remote-key functions still operate. CAUSE BCM steering-lock status testing confirmed the electronic steering column lock failed to report the required unlock state and authorize ignition power-up. CORRECTION Remove and replace electronic steering column lock unit. Complete required steering-lock registration and verify push-button starting operatio

CUSTOMER CONCERN Customer states the malfunction indicator light is on. DTC P0A93 is stored, and the inverter water pump runs briefly before shutting off when commanded with a scan tool. CAUSE The pump retained battery voltage and ground but would not continue operating, confirming an internally failed inverter water pump. CORRECTION Remove and replace inverter water pump. Refill and bleed inverter cooling circuit, clear DTC P0A93 and verify commanded pump operation.

CUSTOMER CONCERN Customer states the vehicle will not start after the discharged 12-volt battery was replaced. DTC P0A0D returns immediately. CAUSE Inspection confirmed the high-voltage battery service-plug grip was not fully seated, leaving the safety interlock open. CORRECTION Correctly seat and latch the high-voltage battery service-plug grip. Clear DTC P0A0D and verify READY-mode operation.

CUSTOMER CONCERN Customer states the malfunction indicator light is on with DTCs P0A93 and P0AC4, and the vehicle will not complete its emissions test. CAUSE The inverter cooling reservoir was empty, and inspection confirmed coolant leaking from an inverter cooling-system hose. CORRECTION Repair leaking inverter cooling-system hose. Refill and bleed inverter cooling circuit, clear DTCs P0A93 and P0AC4 and verify coolant circulation.

CUSTOMER CONCERN Customer states the tire-pressure warning light is on. DTC C1727 identifies low battery voltage from the left-rear tire-pressure sensor. CAUSE The internal battery in the left-rear tire-pressure monitoring sensor was depleted. CORRECTION Remove and replace left-rear tire-pressure monitoring sensor. Register sensor identification and perform TPMS relearn.

CUSTOMER CONCERN Customer states the malfunction indicator light is on with DTCs P0A93 and P0AC4, and the vehicle will not complete its emissions test. CAUSE The inverter cooling-system reservoir was empty, and inspection confirmed coolant leaking from an inverter cooling-system hose. CORRECTION Repair leaking inverter cooling-system hose. Refill and bleed inverter cooling circuit. 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.

CUSTOMER CONCERN Customer states nothing powers up when the push-button ignition switch is pressed and the vehicle will not start, although remote key functions still operate. CAUSE BCM steering-lock status testing confirmed the electronic steering column lock unit failed to unlock and authorize vehicle power-up. CORRECTION Remove and replace electronic steering column lock unit. Perform required steering-lock registration and verify push-button starting operation.
