Trying to find out about the check engine light staying on. Please share any information on the topic.

My 4xe's check engine light went on at 1,800 miles. After a bunch of internet research, I checked the gas cap (repeatedly); no luck turning off the CEL. Then I checked the fuses. Nine of them were not seated properly. I tightened them. CEL is still on so I do not think these two commonly cited problems are my CEL issues.
However I do have one other issue that I think MIGHT be related to the CEL. I'd like you to tell me if this has been observed or considered.
I am charging on a 220V Level 2 charger. Occasionally I will go to the garage after an overnight charge and the 5th charge light is still blinking and the car says it is only charged to 99% despite having as many EV miles available as when it charges to 100%. Here is where my theory comes in: as I understand it, the EV must send a signal to the charger that the vehicle is "full", at which point the charger stops trying to feed the car. What if that line of code in the 4xe is "bad", i.e. not telling the charger to stop feeding it? Would that trigger a CEL?
If so, is anyone working on a software update that would address this issue?
Any feedback you can provide would be very much appreciated!
