After checking the vehicle, DTC B10A3:86 may be stored with or without other DTCs. Follow the repair procedure below for B10A3:86. Customers having this concern should have their vehicle repaired using the following repair procedure.
SA-019-24b2024-08-03. Service bulletin. ELECTRICAL SYSTEM; ENGINE. Some customers may experience a vehicle no start (no "Ready-ON") due to the 12V battery discharged or the High Voltage (HV) battery discharged. This may be caused by: Ignition left ON when exiting the vehicle (exiting the vehicle during "Ready-On"). Door/liftgate opened multiple times without ignition "Ready-ON" or driving vehicle. Installation of aftermarket electronic devices. To minimize the battery drain concern, ensure that the vehicle shift selector is in Park when exiting and verify the ignition is turned OFF when exiting. NOTE: If multiple door/liftgate opening without "Ready-ON', drive vehicle to charge 12V battery.
SA-018-24a2024-08-03. Service bulletin. POWER TRAIN. The 7G large platform utilizes a new 8-speed automatic transmission. Due to changes in the parking lock mechanism, which is now hydraulically operated, the neutral range in the transmission can only be achieved if the engine is running (or “Ready-On” for PHEV). With this design, there is no provision to manually engage neutral. This can cause challenges to dealers, customers, or towing providers when a vehicle cannot start and can't move, usually due to a discharged (dead) battery. In the event that a vehicle cannot be started or achieve “ready-on”, wheel dollies must be used to allow the vehicle to be rolled and moved. NOTE: The following procedure is for moving vehicle around the service shop and not for towing purposes. Please reference the owner's manual for towing instructions.
