The turn signal lights weren't working?
Are the tire pressures reading ---? Message on the DIC? Did you try with the tool? You know releasing air does not work on all 2010?

 

Was sitting in the car when I was trying, so I didn't see the turn signal. Tried it by releasing air, then with TPMS tool.

I think I'm going to try these: external TPMS sensors, they just replace the valve stem caps, and a set of 4 are cheaper than one AC Delco TPMS. Supposedly, they are "Compatible with GM branded vehicles manufactured after 2006", and only require the included tool (same one I already have) to activate.

I have these in my 2011, they work and are inexpensive

Two reason's I'm going to try the ones I linked other than price:
1> They are external TPMS Sensors - so you don't have to break the seal on the tire, pull out the old sensor, put in the new sensor, re-seal tire... it's just swapping valve stem caps.
2> They have user replaceable batteries, so, in theory, just one purchase of sensors, then new batteries every few years.

 

But then some kid likes that cool look for their bicycle and takes one or two. My dice valve caps I made disappeared while I was getting changed to go to my Friday night car show. It happens.
Keep us updated on these caps.

 

That is a possibility, but because they are under constant air pressure, they have to be tightened with a wrench, so a little less likely to happen.

 

? The valve stem doesn’t hold the air pressure in?I watched the entire video, I see the lock rings and orings to install.
seems like these will work

 

Senior moment?

 

Ci, senior! More just a lazy assumption of the facts, that’s why I watched the video! Learned something new.
