My model year 2014 Model S just had a weird failure today. I dropped my kid off at school and went to the gym as usual. I returned to the car after my workout, but the screens were blank, and I thought it was just one of those occasional system reboots that happen to us all. No big deal right? Takes 20 seconds and you're driving again.
Nope.
The screens came up and I got a warning message that the system was shutting down and a variety of related messages, that kept appearing when I tried to put the car in gear.
I called Roadside Assistance and told the what was happening. The nice lady pulled up the logs and said my car was reporting a 12V battery problem. I thought that was weird because there were NO warnings ahead of time, and I have experienced a failing 12V battery once before. Normal warning, service changed out the battery ... all good.
I just left my car at the gym and walked home. I researched things and realized I could boost the 12V battery myself, so I got the equipment together and went back to my car about 2 hours later.
NO ISSUE - the car just started as if nothing was ever wrong. No error messages, and I did NOTHING. I did not boost the battery.
Anyone have any idea what that might have been?
Side issues, perhaps, and perhaps related issues ... mobile service came to fix my door handle recently and could not repair it. But in the process of the repair, Fuse #40 (rear door controller power) blew. I had to diagnose this problem myself and let the ranger know by text message. He came back, fixed the fuse issue, tried again on the door handle and still couldn't fix it because it might have been a cable assembly issue in the door itself.
I started to wonder if a broken cable assembly could cause the 12V power to go down intermittently.
Thoughts?
Nope.
