CAUSE Confirmed open circuit in the M40 rear compartment lid latch wiring between connector X900 pin 16 and the latch on the dark blue/yellow wire. CORRECTION Repair the open M40 rear compartment lid latch circuit and verify trunk release from the interior switch and key fob.

CUSTOMER CONCERN The engine intermittently will not crank and may stall while driving; DTCs P1682, P0AC4, P069E and P2534 are stored across the ECM, FPFCM and HPCM. CAUSE The confirmed repair identified an intermittent ignition-switch fault that dropped ignition voltage and caused the module low-voltage and communication symptoms. CORRECTION Remove and replace the failed ignition switch, clear P1682, P0AC4, P069E and P2534, and road test to verify the engine no longer stalls

CUSTOMER CONCERN The malfunction indicator lamp is on with DTC P0C32, and the hybrid battery-pack cooling fan is inoperative even though it had previously been replaced. CAUSE The G14 hybrid battery-pack cooling fan motor failed again; the power, ground and variable command circuits tested correctly but the fan did not run. CORRECTION Remove and replace the failed G14 hybrid battery-pack cooling fan, clear P0C32, command the fan through its speed range, and verify battery-coo

CUSTOMER CONCERN Engine runs rough at idle with DTCs P0016, P0089, and P228D, and the engine oil level is approximately three quarts low.

CORRECTION Remove and replace the timing chain and correct the failed upper-guide condition.

CUSTOMER CONCERN The malfunction indicator is on with DTC P219A, no misfires are present, and long-term fuel trim remains in the single digits. CAUSE Flow testing found one fuel injector delivering substantially less fuel than the other three. Cleaning did not restore the injector's flow. CORRECTION Remove and replace the low-flow fuel injector, confirm the replacement injector matches the remaining injectors, and road test to verify DTC P219A does not return.
