I have a 2012 Buick Lacrosse A few days ago it wouldn't start and appeared to be the battery or related issue. I just started it, ran it for a while, then turned it off and restarted it just fine. Well a few hours later it wouldn't start again. I jumped it a second time and took it to Autozone to be tested; the battery, alternator, and starter were all said to be fine. I replaced the key fob battery and nothing. I checked the fuses and they're all fine too.

So basically the car doesn't have power for ANYTHING, the key fob won't lock/unlock anything, and I can't push the brake down to put the car in neutral ... but the car will start and work fine when jumped. What could the problem be?

I had the same problem . Battery and alternator are replaced a month ago when I observed this problem but just a moth after got the same issue car (Volvo XC60 2017) won't start. Sometime If I try restarting it over a few times the whole power goes off. no power for lights no even lock/unlock. I suspect some parasitic power drain is happening. If the check engine light also shows up during the failed starting conditions this could be fun pump issue . But Jump start always work.
