I have a 2009 Lexus LX570. I've owned it for a couple years and love it! It has 180,000 but it's in perfect shape. Anyway, I was on an extended business trip for 3 1/2 months and it sat in my garage and wasn't started. When I returned I had to jump it but it started and everything was fine. Then a couple weeks later it wouldn't start right up when I pressed the start button. The steering wheel would come out and it would act like it was going to do something, but it wouldn't do anything. I would push the button again a few times and eventually it would start. My first thought was the battery, so I had it replaced and it was ok for a day. Then it would do the same thing in the mornings, have a hard time starting. Not slow cranking, but like it's just not connecting or there's way too little voltage to turn the motor. Clicking etc. So I took it to the place I got the battery and they tested the battery, the starter and the charging system, all of which checked out fine. That was yesterday, we drove it around all day without issue and then this morning, it will not start. Not even with a jump. I have a battery charger with a start booster and it wouldn't work, I tried one of those little battery boosters and it didn't work and I tried to jump with another car and nothing. The steering wheel goes in and out when I push the start button but it will not turn over.
 
99% starter / starting solenoid

You got more life and warning shots than most. It usually gives very few hints before never starting again.

 
It's often precipitated by low battery voltages because of the way motors or inductive loads work. It will draw significantly more current in place of voltage which really stresses/overheats contacts. Usually the last straw for a worn starter relay.

This is why I'm religious about replacing worn starter batteries to the moment they show any reserve or starting weakness.
 
Yup, time for a new starter. It’s not surprising it tested good. Typically the solenoid either works or it doesn’t, so there is no useful test for it.
 
Here you go, good luck
