TPMS

[javer]

I have a 2021 Telluride SX Prestige and when I drive about 30-45 miles the TPMS goes off (not every time but most of the time). My tire pressure on all tires is fine. Once I stop and turn the SUV off the TPMS warning light goes off. I took the SUV to the dealership and since the light was not on they said there is nothing they can do. It's obvious that one or more sensors are bad. Any thoughts on how to correct? I have driven 30 40 miles just so I could have the sensor go off and take to the dealership but the light never came on. It's nothing too serious but it drives my crazy.

What are your tire pressures measured at each tire?

Sounds like you have a “special” kind of service dept and should give you more than “cuz”. That said…
Make sure the tires are all the same pressure and above 35(I like 40psi myself).
If they have a spread of more than 3psi it will generally throw the light. If those parameters are met, and the light still comes on, and since the dealer is special… drive to the dealership with the light on and don’t turn off the vehicle so they can live scan the code. Or, once the light comes on, see if one wheel is not registering the psi. And take a photo to show them.
