I've had this issue about three times now where I'll jump into my BRZ Limited with push start, press clutch, push "start" to turn the car on but then the car will just have one "click" then the lights are off. I'll try to go into accessory mode by pressing "start" without the clutch and nothing happens. The car seemingly dies.

I'll wait a while, clutch in, push start and hold and I can hear the "clicking" noise multiple times but nothing happens. My battery voltmeter (plugged into center console) shows 7V. After this, I can go into accessory mode, the nav screen pops up but still can't turn the car on.

The first time this happened about 2 months ago, I thought it was my battery. However I replaced it about a year ago. As I was trying to jump it, I noticed the positive terminal just lifted off the battery nub, so I tightened it and that "fixed" the problem that time. I was able to start the car afterwards, I thought that that was the issue.

The second time happened a few weeks ago but I just sat in the car, trying to start it a few times, but then just stopped for about a minute to think to myself and then it started up with no issues. Weird.

The third time was today in the morning after the car sat overnight (don't remember the other two instances). I waited a minute again but nothing so I jumped out and was going to jump start it. I paid attention to the terminals on the battery and they were all tight. I didn't jump start it, but all I did was remove the negative terminal, waited 5 seconds, then reconnected it. Then I was able to start the car up.

ANy ideas on where I can start diagnosing this? I don't believe it's because of a dead battery from a draw overnight since I was able to start it today just by removing and reconnecting the negative terminal, that couldn't have reset and given it enough life to start the engine right?
