I have a slow leak and the air seems to be leaking from the tire stem.
Can I get this fixed at a regular tire shop or do I have to bring it to the dealer?I asked this because I heard that the stem is connected to the tire pressure sensor..true?

 

Any tire shop with knowledge of the TPMS can fix this issue. Sounds like you have a bad seal around the stem or the stem may be bad itself.

 

I'm thinking it might be a bad seal because it's not leaking from the top of tge steam(were u pump air at) but it's leaking from the bottom

 

Okay. The TPMS basically just screws onto the valve stem so it shouldn't be a biggy. If you go to a Town Fair Tire they should be able to take care of it.

 

+1, any reputable tire shop can handle it. Call ahead, tell them the stem is leaking you don't know where and you have TMPS, and ask them to quote a stem replacement.

 

i had a crack in the actual valve stem

 

4sure
I'll bring it to the tire shop

The Infiniti Stealership is the last place you want to go, if it's tire/wheel related always go to a reliable tire store in your area. If the sensor is bad and needs replacing check with a Nissan dealership, the cost will be considerably less!

Thats a great tip. Might get TPMS for my winter wheels next year if these are affordable.

 

You right and I should know better because I called tge infinti dealer to get some M/T gear oil and they told me it was $17 a quart then I called Nissan and they told me $11 quart for the same oil

 

I had air leaking from the valve stem, and it ended up being a crack in the metal stem itself of the TPMS, and the whole thing needed to be replaced. They can usually be found pretty cheap on the forums though.
