My Sedona in my sig sat for just over 2 weeks while we were on vacation. I start it up yesterday to head into the office and all was well. When I left the office about 3 hours later however, while heading down a sidestreet, I suddenly lost gear and every light on the dash lit up like a Christmas tree. 2 seconds later it was back to normal, no CEL or anything. So I made a stop at the bank, and when I go to unlock my van with the fob, nothing. I manually unlock the door and stick the key in the ignition, and a few displays try to come to life, but are very dim. Sounds like a dead battery right? The voltage was at 12.8v at rest, which doesn't mean much. But here's where it gets weird... I start wiggling the steering wheel for some reason, and everything kicks back to life! Displays, radio, fan, etc. Van starts just fine. This also happens a second time about 10 minutes later at the post office. Out of curiosity, I then have my battery checked at a local autoparts store, and it indeed is bad. Previously the battery would only reach 13.3v at idle, whereas the new one reaches 14.2, which sounds about right. So all is well, van works fine.
Fast forward one day and 200 miles later, and my van again will not start. The remote unlock worked, and when I went to start, nothing. All gauges are off or dim, clock has reset, etc. So I pull the positive battery terminal cover off to check the fuse block (there is one integrated into the + terminal) and all looks fine. Everything is tight and clean, no corrosion. I then snap the cover back on, and I hear all the electronics come back to life. Huh?! Van then starts fine and the battery is 14.2v at idle. Do I have a bad connection somewhere? All fuses also look fine, FWIW. I thought the battery was the culprit, but now I'm not sure. Alternator seems to be charging just fine.
tl;dr, van won't start, electronics have no power, then jarring the vehicle brings it back to life with full voltage.
I swear I have had so many odd issues with this van, many of them being of the electrical variety.
