It's official, Bear is the most jealous vehicle I've ever encountered
My work has a jobsite near Harrisburg, PA. I've been there three times, including today's trip (done with either the parents' hybrid or a company car). Each time after coming home, I've encountered some kind of issue with Bear. After the first trip, I started it the next morning to find my main battery had a failing cell. After the second trip, my LED doorhandle lights started failing.
Today, we just finished eating after I finished up at the site and were at a bike shop across the street. As we were walking out the door to leave, I get a text message. It was the OVMS module warning me of a critical 12 volt battery! I immediately send a DIAG? command to the module. It reports back with a voltage even lower than the warning (warning message said 10 volts, DIAG? response said 9.4 volts). We get home, and sure enough, the car won't unlock with the remote. I unlocked it with the key, popped the hood, and put the 12 volt charger on the battery for a few minutes, then took it off and plugged the car into level 1.
So, now I need to figure out what caused the battery to run flat over a 3-day weekend and how to fix it. There were no lights left on, so that leaves:
A. The radio was stuck in a powered state.
B. The 12 volt battery is weak, both from a year of sitting on the dealer's lot and from running flat a couple of times while the main battery was being replaced.
C. Power draw from the OVMS module, the OBDLink, and the radio is too high for the size battery in the car to last more than a couple of days.
So, does the 12 volt have its own warranty, or is it part of the new vehicle 3-year warranty?
