Well you need to read the codes.
Also what year?
Have you checked the spare tire area for water?
Have you checked if your front drains are clogged?
These fill with water and cause random and some not so random fails

Ok thats a vast range of faults which still makes me think water damage or wet components.
Have you checked the spare tire area for water?
Have you checked if your front drains are clogged?

I googled these, but like I said they are far ranging and not likely actual faults more like something else is causing ghost failures.I made a video on how to
check front drains. It requires you to remove a few screws on the front tires wheel wells so you can reach up and pull out the drains.
beware though, if they are clogged a ton of water will come flying down onto you lol.
05635 internal control mod failed self test
01671 sensor adaptive cruise control
01541 Lights rise
01540 Lights go down
01617 memory Interrogate interior protection system faults
01689 Electromagnetic dampers suspension manual control valves
01579 seat occupancy sensor passenger
05668 MIL Request Signal Active
some are here some different descriptions but essentially the same
