some electrical problems are tied to the computer system/accessories needing to be flashed too - with that variety of issues have you taken it in to either a mechanic that can handle electrical or to your dealer? do you have aftermarket items like radios etc that might also need to be flashed?
We have a 2017 Compass that we upgraded the radio on - ran great for near 8 months in that config - had a problem with the hot air system for the heater - they replaced an actuator and flashed the onboard computer - after that for weeks we had issues where the battery was running down - turns out that update then required our radio to update - it was NOT a hard failure or drain it was a conflict that was created when the dealer updated the onboard computer - now that we have that all worked out everything is 100% fine again. Sometimes it is a bad drain from some hardware - sometimes it is computer based - but you need the right people who check everything not just assume.
