My vehicle type is a Ford Focus electric, the module is still in the early stages of development.

That's how it is for me, too. I have read-only access to the CAN buses without additional polling. After some time I notice that the values are no longer updated, if I then look at the bus with 'can can2 status', I see that neither interrupts nor packets come in, although the bus is definitely still active. Either a module reset or a restart of the bus let the messages flow again.
 On which bus do you have the problem? So far I could only observe this on CAN2 and CAN3. CAN1 was not stalled as far as I can tell.
 Kind regards,
