I was driving along at highway speeds (between 70-75 mph) when my dash and tire sensor lit up with warnings. I immediately pulled over and checked the warning on my tire pressure screen. It showed dashes where it typically shows a tire pressure (all other tires showed 35-37 lbs). Sorry, no picture available.

I used a manual tire gauge and checked the front driver’s side pressure and it read 37 lbs. I checked the tire for any road debris (nails, screws, etc) and saw nothing. I listened for a few seconds and heard no sounds of air escaping. I felt confident at that moment that it is probably a faulty sensor.

A police officer happened to pull over behind me as I was getting into my vehicle. We talked about my issue, showed him the gauge, and he agreed it was most likely a sensor issue. I pulled away and drove slowly to begin with, but eventually went back to highway speeds with no issues. I have continued to drive on it for the last week with no issues to the tire, so I still feel confident it is probably a faulty sensor.

I have searched on YouTube but I cannot find any videos on my exact issue. I suspect I’m not using the correct verbiage or maybe I’m being too specific in trying to find a video on my make/model. Or maybe I’m completely wrong and there’s something else wrong that I don’t have the knowledge to articulate. Either way, I can’t figure out if this is a relatively easy fix or if I need to take it to a mechanic.

Any suggestionst on videos, DIY repairs or recommendations to just take to a mechanic? Thanks in advance!

Anyone have Thule or Yakima cross bars on their '21+ Tahoe/Yukon? Are you still able to open the sunroof? Specifically when loaded with 2 Kayaks. And/or what setup are you using?
