Could be a few things. First thing I'd try is to just hit up the entire wheel and tire combo with soapy water again to confirm where the leak is coming from. 7psi a week is something to be concerned with so that is an easy step to do that won't cost you an extra money. You might have some dirt or something along the bead/seat, so it's not really holding air like it should.

FYI, the TPMS unit can be replaced with a generic unit (http://www.amazon.com/Schrader-20161.../dp/B002GYSR9E
I replaced all of mine a year ago after the batteries started to die in them. My dealership reprogrammed them for free.

Before replacing the sensors, look into the rebuild kits which replace the rubber sealing components of the TPMS sensor preventing leaks. usually, when you get new tires on, you are offered this service.
Losing 7psi a week is a LOT to not notice air bubbles. The soapy water trick is usually foolproof. I'd really consider searching the tire again. I'd fill the tire up to the MAX psi on the sidewall and just go to town with soapy water everywhere. On the beads, everywhere on the tread, take the valve stem cover off and spray inside.
You should see bubbles somewhere.
Might be easier to remove the tire and search. Might have a small nail or glass slice on the inside part you can't see.
If could be the TPMS sensors too. Could always try the rebuild on 1 tire and see if that works

Yes. Last time I got tires on my g35x they rebuilt the sensors. I actually prefer having the TPMS sensors over regular valve stems. The system comes in handy when the temps drop and it tells me I need to top off the tires.

I am in NY. There's a discount tire not too far away. How can it repair for free?????? I don't get it. First they have to take tires off, then either patch it or stick that sticky tube into your tire and mount it back. Free???????

Maybe I'll get 4 and just have them rebuild it. While they have tires off, I'll just have them rotate it for free. It's due for rotation anyway and I've been really lazy about doing any car work. Used to go under the car quite often but once you get lazy, you just want to do less and less.
I actually had these move from the OEM 17 to the 18's three years ago. It was not rebuilt. The TPMS was just moved over.

The only thing I haven't tried is taking the wheel off. I've sprayed soapy water on sidewall, rim/bead area, inside of valve core. Also looked at threads for nail. Can't find anything on the 3 tires. I didn't look at the tire facing the inside part of the car though. But the odds for 3 of them having inside cuts? Which is why I think the near 8 yr old TPMS is the culprit. I can definitely take the tire off and check I guess.

Maybe it's work? Maybe having a 5 year old kid? LOLI actually ordered 4 tpms rebuild kits. Gonna just bring it to shop have them check for leaks, if they can't find it then I know it should be the TPMS. Just have them rebuild it. If it turns out to be cuts in the inside of the tire, then time for new tires I guess and can still rebuild TPMS with new tires.

Totally understand. I have hydralic jack , jack stands and even impact wrench to take it out but just been really lazy doing any car stuffs nowadays. Maybe it's work? Maybe having a 5 year old kid? LOL
