My tire pressure light keeps coming on and going off at odd intervals when I am driving on the highway. I check my tire pressure every weekend but the light flashes on and off inconsistently, sometimes working fine for days before flashing again. Do I need a new monitoring sensor?

If all your tires are inflated to the correct pressure, first try and add a few extra psi to each tire and run with them for a week (say 36-38 psi).

If the light still acts up, it sounds like something within the TPMS isn't working correctly. Have it checked at the dealer, since I'm sure it's still under warranty.

I'll try that, thanks.
