Battery Draining
Bought used 2016 Lexus GX460 approx four weeks ago twice in last two weeks the battery has been dead after sitting for about an hour or two after driving it to or from work (30 minute drive). Still under warranty w/30k miles. Battery tests fine, thought maybe my radio was playing through my bluetooth since my car sits right outside my office window but I am certain I did not leave anything like that on this time. Any thoughts on what the problem could be. I've never had a car with the push button start & stop and am wondering if I am going something wrong here.

If it’s under warranty, I’d have the service department diagnose and spend time with it.
Besides that, take a look at the fuse box in the engine bay and under the steering column. Maybe the previous owner or the dealer had soemthing aftermarket installed that is starting to drain your vehicle.

How many feet away is vehicle parked from the key at your office window?

Hmm, this brings up a question that I am not sure of....If you use auxiliary and walk away with the FOB/Key will the GX drain the battery or shut down with loss of comunncattion with the key FOB?
My setting is one touch stereo and Nav, second touch is head lights and cabin fan running

I'm having a very similar issue with my 2013 GX. the first time it happened, i assume that the OEM battery was dead after 6 years, so I replaced it. then it happened again and appeared to be a rear dome light. now it's happened a third time!

What voltage are you seeing with a multimeter while vehicle is running and accessories turned off?
