CUSTOMER CONCERN The check engine light is on with DTCs P2450 and P0442 stored. CAUSE The confirmed failure is the fuel-vapor vent valve in the evaporative-emissions system. CORRECTION Remove and replace the EVAP fuel-vapor vent valve.

CUSTOMER CONCERN The check engine light is on with DTC P0130; the vehicle may otherwise run normally or surge while driving. CAUSE The confirmed failure is the universal heated oxygen sensor at Bank 1 Sensor 1. CORRECTION Remove and replace the Bank 1 Sensor 1 universal heated oxygen sensor.

CUSTOMER CONCERN Power steering assist is inoperative, and DTC B2278 returns after it is cleared. CAUSE Testing and confirmed-fix history identify a failed steering shaft torque sensor in the electronic power-assist steering system. CORRECTION Remove and replace the steering shaft torque sensor. Perform the required steering torque and steering-angle sensor calibration.

CUSTOMER CONCERN The vehicle intermittently enters limp mode with DTCs P0A7C, P1A0D, P1A0E, and P1A0F stored. CAUSE The confirmed failure is the Motor Electronics Cooling System pump, which is not circulating coolant through the hybrid electronics cooling circuit. CORRECTION Remove and replace the Motor Electronics Cooling System pump.

CUSTOMER CONCERN Customer states the oil-pressure warning light comes on while the engine is running. DTC P0521 is stored. CAUSE Mechanical oil-pressure testing remained normal while scan-tool pressure stayed low, confirming a failed engine oil-pressure sending unit. CORRECTION Remove and replace engine oil-pressure sending unit and inspect or replace the sender screen. Clear DTC P0521 and verify the warning light remains off with stable pressure readings.

CUSTOMER CONCERN Customer states the airbag warning light comes on intermittently after the driver seat-belt pretensioner was replaced. SDM DTC B0015-0D is stored. CAUSE Inspection at the driver-side B-pillar confirmed poor terminal contact at the driver seat-belt pretensioner connector and its connector-position assurance device. CORRECTION Repair driver seat-belt pretensioner connector terminals and secure the connector-position assurance device. Clear DTC B0015-0D and veri

CUSTOMER CONCERN Customer states the engine runs rough and enters reduced-power operation. DTC P0121 is stored. CAUSE Throttle-position data and connector-terminal testing confirmed an internal throttle-body position-sensor fault. CORRECTION Remove and replace throttle-body assembly. Perform idle-learn reset, clear DTC P0121 and verify throttle response and normal power.

CUSTOMER CONCERN Customer states engine oil pressure drops intermittently and reduced-power operation occurs. DTCs P0011 and P0521 are stored. CAUSE Mechanical oil-pressure testing showed pressure falling after warm-up. The engine oil was low and approximately 15,000 miles overdue, restricting camshaft-actuator oil control. CORRECTION Flush engine oiling system, replace engine oil and filter and refill to specification. Clear DTCs P0011 and P0521 and verify warm oil pressure

CUSTOMER CONCERN Customer states the passenger-front and both rear power door locks do not operate, while the driver-front lock works normally. No BCM DTCs are stored. CAUSE Gray and Tan lock-circuit voltage changed correctly when commanded, confirming the passenger-front and rear door-latch actuators had failed internally. CORRECTION Remove and replace failed passenger-front and both rear door-latch actuator assemblies. Verify lock and unlock operation from both switches and

CUSTOMER CONCERN Customer states the Service Charging System message is displayed. ECM DTC P0621 is stored. CAUSE L-terminal command and Orange-wire voltage testing confirmed the control circuit was operating but the alternator did not respond correctly, identifying an internal alternator failure. CORRECTION Remove and replace alternator. Clear DTC P0621 and verify charging-system output and L-terminal command response.
