I've probably read through 50+ posts about this but really didn't see anyone come to a finally answer on what needs to be done.

I have an 05 G35 Sedan with about 50k miles. I'm on my second set of tires and it seems shortly after I had the tires replaced my light would come on after driving on the highway which from what I understand indicates a high PSI since when it's low it flashes and chimes. I've checked the pressure and made sure that they are at 33 as indicated on the sticker in the door jam.

What else can be done, what kind of cost am I'm looking at to fix this issue?

 

May need to replace one (or more) of them if they've been exposed to a lot of weather, etc. Or they may simply need to be recalibrated, which any dealer can do for not too much money.

 

^^ What he said.

 

So my only option is dealer to have them look and I could end up paying them to replace one or more? Do we know at what cost this is?

 

Most tire shops aren't going to have the special tool required to recalibrate the TPMS, so yes, your best bet is to go to a Nissan or Infiniti dealer to have them assess the situation.

 

Ok thanks for the help, depending on the cost I might just have to live with it.
