Low tire light stays on, tires are full, how do I get the light turned off?

 

In the instrument cluster your can see the individual tire pressures. See which one is not reading and it probably would be the 1st one needing replacement. 

As @1004ron stated, they are probably at the end of their life and their batteries will eventually discharge requiring the sensor replacement.

What they said.  I have a 2016, and replaced my first one about a year ago.  Just replaced the second one a month or so ago.  I'm sure the next two will be coming up before too long.  Cost $134 at the dealer to change it out.  I got it done while I had it in for oil change and other service.  Easy peasy.

I bought four off eBay and paid Big O Tires $20 a wheel to pop the bead on one side and install the four new sensors.

 

Big O also did the learn procedure although I have the equipment to do that and this.

 

Total cost for all four wheels $110

Remember the good old days when you used your eyeballs to look at your tires and if one looked low, you added air?

And it was free!

This is one of the modern "gimmicks" that I'm glad to have on my three vehicles.

 

My Edge gave me an alert while I was on the I-71 and constantly displayed the current pressure as it decayed which allowed me to get off the interstate to install the emergency spare.

 

My BMW K1600 motorcycle also alerted me when I had a slow puncture before it became an instability risk.

 

Just last month my wife's BMW X5 alerted her to a slow puncture - allowed her to make it home for me to repair it.

My 2016 Sport learned the new sensors by itself. 

I have also confirmed before that it also relearns the sensor locations by itself. I still have not figured out how it does it. 

 

I had made a video few years back were I moved one wheel from the left rear to left front, it was overinflated. You can see in the video how the readings change.

Yes, I do.  I also remember you could not tell how low the air in your tire really was by looking at it.  Sometimes it looked that way based on how the car was parked.

 

But, almost nothing is free anymore, including air at the station or the air we breathe.

I knew I shouldn't have responded to this post.  I knew I would jinx it.  And sure enough, I took off today and damned if the TPMS error didn't pop up.  Driver's back tire.  When I left to come home, it didn't come on again, but it did come on just before I got home.  So yeah, number three down.  

 

As far as buying the sensors and stuff, I know I could probably get it done cheaper (we don't have a Big O's here...just Discount Tire and some local things), but sometimes it's just easier to get it done while getting other stuff serviced at the dealer.  I'm too old to care anymore, and I can't do the stuff myself anymore.  So I'll feed the dealer unless it is stupid expensive.  At that point I can just dump the car anyway.  But so far, I don't see that happening.  It's doing me good.
