Bad 12V battery -- with advance warning!

Once you get your new battery, try your air pump routine with the car just in ACC (one push, no brake pedal) instead of ON (two pushes, no brake pedal). I think the power outlets are active in ACC, but a lot of the car's normal electrical loads are not; that way you're not sucking as hard on the battery while there's no support from the hybrid system.

I had one of those little inflators once, but I eventually wired a larger compressor into the car instead. That solved a few things that used to annoy me:

• There's no TPMS in the spare, and I'm really bad at remembering to regularly check it. When I wired in the compressor I just set it up to keep the spare at 60 psi, out of sight, out of mind.
• Instead of a little slow inflator to plug in and lug around, I just have a coiled-up air hose living in the small storage bin off to the left of the hatch area. It's always connected to the spare tire, which is always 60 psi. That'll top off any of the four lower-pressure tires in seconds, just push the chuck on and squeeze the trigger, much faster than the typical small inflator.

With a blow gun on the end it's also great for blowing tree gunk out of gaps and under the hood, etc., and a few times I've used other small air tools (but only for very light work).

 

How about you check the voltage of the battery? It is also good indication of the battery health.

Also, you can now get those battery operated tyre pumps. I am using Xiaomi portable air pump and it works great. I too have small leaks on two of my tyres.

 

If you have small leaks, you should find out why. You either have a nail, or screw, or some other object
in the tire causing the leak. Or the valve is not completely sealing, or the valve core is leaking.
Or the tire is not sealing around the rim.....

 

An even better plan is to actually put the car into "ready" mode to put some power back into the 12 V battery and don't obsess if the gas engine actually starts for a minute or two.
Yes, at this point I agree that a new battery is probably needed. Along with a way to fully charge it.

An even BETTER plan is to get your tires fixed.
WalMart does it for about $7.50 per patch-plug device......assuming it is a simple puncture.

What ever is causing it may suddenly fail completely while going down the road.

 

I found my tyre leak. It's from the valve stem. Only way to fix it is changing the valve stem. I might as well change the tyre cause it's due anyway. Just waiting for some good deal on the tyres as mine is using 18" low profile tyres which cost a lot for 4 pcs of good quality low noise brand.

 

It’s a so-so indicator? An electronic load tester is better. I’d recommend Solar BA9.

 

That's good! You can use any valbe core. Even from a bicycle tube.
That would keep you from having to constantly fill the tire.
Or is it the actually vavle where it's attached to the rim?
There's a kit to repair the TPMS unit. Or when they replace the tire they can remove it,
clean around where it attaches, and reinstall it. MAYBE a dab of silicone to seal it.

 

Toyota sells the washer and the nut separately that hold the TPMS sensor/stem in place; they can be replaced from the outside, are not considered reusable, and should be replaced with new any time they're removed.

There's also a fitting kit that includes both of those and the grommet that goes on the inside. The tire has to be dismounted to do that.

Yire shops should have versions of those parts in stock, because they're officially supposed to loosen the sensor/stem before any dismounting of a tire, and reattach it with new grommet/washer when remounting.
