weird electrical issue and “Hill assist start” fail spam - 2014 Focus SE Hatchback
I’ve been having this weird issue where sometimes while driving “hill assist start” as well as my parking brake and traction control light will flash and play a tone for 1-2 seconds and then shut off again, I find it mostly happens when I begin to accelerate from a complete stop
however the larger issue is that, when that begins happening the next time I shut off my vehicle, it fully shuts off, no light, no cranking or power. Oddest part is the fact it will turn itself back on after a few hours of sitting. this has happened multiple times and i’ve had it looked at by two different mechanics with mostly no luck
i’ve gone through two batteries already, and the current one I have has been checked as is good. I also know the issue is not the alternator or wiring harness issue as i’ve had those checked as well
i’ve seen things on the sub saying it may be the 50A fuse on the front of my battery box is that worth checking first? should I just swap out every fuse?
has anyone else had a similar issue?
