Intermittent TPMS Light

I’ve got a 2014 Limited with 193k miles.

On a drive from Texas to Minnesota and back, the TPMS light would come on intermittently. It only comes on at highway speeds (over 70). It’ll flash for a minute then stay on. After a while, it would turn off. I can’t figure out any rhyme or reason.

And yes, I checked all four tires and they are all properly inflated. Any help would be very much appreciated. Thanks.

 

Sounds like the TPMS battery needs to be changed.

 

The battery lifespan in the sensors is on average about 10 years. If they are original sensors, you will need to replace them. The batteries in them are not replaceable.

 

Mine did the same (2016). I just had the tire shop replaced all four of them when I needed tires. Learn to ignore it for now and check your tires occasionally.

For me, it wasn't worth paying for dismount, tpms install and remount because I knew I needed tires about a year after the issue started. Obviously your situation may be different.

 

I'm on my 15th year. They used to light up(and turn off) only when cold weather, but they finally died. Its warm and they're on. Time to change for real.

 

Damn. This is what I feared. My wife has a Lexus GX similar age and mileage and hers started doing this about a year ago. She was told the same thing. Thanks for the input.
