A few days ago my TPMS came on (flashing on startup then stays on), checked all the pressure and they are all 35 cold. Haven't had any problems in the last 2 years....any ideas? Is there any way to do a reset or calibration?

 

I know theres a DIY way to reset it, but its a little complicated. Maybe the TPMS has given out.

 

Recheck your tire pressue again before taking it in, make sure you don't have a leak. Don't go to Infiniti, Nissan can fix your TPS and won't charge you as much....call and ask.
