could this or the bms sensor cause the electric windows start stop and hill assist to not work?

The sensors will not stop the electric windows working. A low battery State Of Charge will stop them and also disable Hill Assist.

Stop/Start is something not worth even talking about.

Use a multimeter and measure the battery terminal voltage approximately 1 hour after parking. It is probably below 70% and therefore needs charged.
