Multiple alarms relating to PSCM front sensors, adaptive cruise, lane assist, self park, hill start, down hill control

So I recently had all of these alarms + come up at once, I could turn the car off and reset and some times it comes on sometimes it doesnt.
For have said this has been caused by..
Job 1 – Lhf inner cv boot split. Requires drive shaft replacement.
Job 2 - Pscm has puncture power steering rack boots causing water ingress into rack. Various warning lights coming on incl steering wheel sensor, yaw sensor, camera module, puddle lamp. Brake control module A, Abs module. Need to replace steering rack, then recheck for any further issues.

I didn't think a puncture boot could cause these issue but maybe as the steering is electric.
Has anyone else had a similar fault?

My theory is the CV Boot is the root cause, dumped out the grease and weakened the EPAS (Gear) boot.
The (EPAS) gear ties into a lot of modules for position inputs and sends it via HS-Can 2 Bus, so it appears the bus is being affected so all listed except (Puddle Lamp?) I do not see a tie in at the moment for that as that is Door Lock & Ajar & Cargo Lighting, however the ABS monitors the Door Ajar circuit, so that is the possible tie in.

Thank you so much for your response that sounds logical.

I had all kinds of faults like that, I opened the hood and smelled something hot and thought I saw a little smoke coming from the firewall side of the fusebox. The dealership I bought the truck from towed it back on a flatbed and checked it out. It turned out the battery cable to the fusebox was never fully tightened from the factory, they cleaned up the connections and ordered a new fusebox as it was partially melted near that battery cable connection.
