I know you must drive the car a ways before the pressure shows up, and, it has been displaying pressure fine until a few days ago, no matter how much it's driven, tires all show as yellow and the three dashes in place of an actual pressure. One maybe odd thing, the display was set from the dealer to display English pressure, but when it stopped displaying, it was displaying Metric pressure. I have changed it back to English, but, still not displaying. The TPMS warning is not illuminated, so I don't think it has anything to do with the actual tire pressure.

Any ideas, or...need to take to dealer?

Thanks!

Mine did something similar after getting new tires. It took a good 100 miles or more before the tpms warning came on. When I took it back to discount tire they scanned all 4 wheels to check for the tpms sensors and found one not functioning. They unmounted that tire and did some kind of rear and it started working again. When one of them isn’t working, none of them will display pressure

This turns out to have been caused by a bad battery, one of the cells was bad. After replacing the battery, no issues...

You stated you have to drive the car a ways before pressure shows up. Do you know about how many miles? I picked up my new ascent today, drove 170 miles and not getting a reading. Thanks

I just had this happen to me this morning on the way to work. Drove on the highway 70+ mph and never got readings on all 4 tires after 15-20 mins of driving. They have been working fine the past few weeks after getting new wheels and tires put on. Super strange. Going to see if it resolves it’s self on the way home later today.
