Any fault codes logged in the Dash CECU? For example this one below is a charging system or voltage fault.

DTC 16800 CECU Control Unit Battery
Voltage
Over voltage The control unit continually monitors the voltage it is
supplied. If the voltage is above 16.5 volts the system will
record this fault. Some possible causes for this fault are
faulty alternator, or jump starting with to high of voltage.
Power is supplied from the power distribution box near
the drivers left foot through the IP harness to the control
unit behind the cup holder.
