This is what I did. The battery voltage rose to where I think it is supposed to be, right above the middle mark. It took 3-4 seconds to get to that spot on the meter (in-dash version). The dealership is now doing an overnight battery drain test. They wanted to say it was the dash camera, but it was installed in June, and never had any issues until it got cold out around Dec 1st.Mine randomly wont start. Today I tried from Alexa and saw the lights flash but it did not start. I went to the door and pressed the fob twice and one flash...Just like what it does when the engine is remotely started and then I want to turn it off, so the computer thought the engine was running. Pressed the fob twice and got the the indications like it was going to start but it didn't, pressed twice again got the one flash like when turning it off.
Next time it doesn't start I'll turn on the ignition and look at the battery voltage.
