I have a '13 FJ Cruiser (original owner) and if I don't start it every day, or if I start it and go a short distance, it will act like that battery is dead. It will start up with a quick jump. Advance Auto checked the Battery (6mo old), the alternator and the starter. All checked out ok. The only aftermarket mods are a remote starter (professionally installed). When I check the draw with a multimeter, it shows a draw of .04a. I don't think that should be enough to kill the battery.

I am at a loss to ever know where to start to looking... any help? Ideas?

Have you tried the remote start when it won't start? Curious also if you checked battery voltage when it does not start to see if its low too? Do the headlights look bright or dim when it will not start?

If voltage seems okay at the time of failure its probably not the battery or charging system.

It could be a loose/dirty connection at the starter, failing starter solinoid or a failing ignition switch.

Start with the free thing first. Clean all wire contacts on the starter. I would move on to testing if power is going to the starter next ( during time of failure ).

I had that at one point, battery was fine one day the other dead, and so on. Ended up being a loose ground connection on battery...That stupid, yeah. Check your connections, clean them and don't over tighten them.

Ditto. Installed my projector headlights and a front camera all in one session..totally forgot to tighten down ground connections. Driving on the freeway vibrated them loose. Check your grounds.

OP: Have you brought it back to the installer to have them double check their work?

Are you still running the original factory installed battery? It may just be losing it's ability to hold a charge. I am on my 2013 .I drive about 40 miles a day. At my 60,000 service the dealer tested my battery and said it was "OK'' but going downhill at about 1/2 of it's original capacity. 6 years on the original battery is above average, they told me. I'm not running anything extra off mine.

It is not the original battery, I bought it new 6 months ago.

Update, still no joy. I have had it at the mechanics and they tested the starter and alternator and said there is no parasitic draw. He suggested I get new battery (its was only 6 months old). So i returned the battery and got new one and installed a battery maintainer to plug in everyday, but this is not a solution and from other posts doesn't seem like an isolated occurrence.
