Intermittent TPMS Fault

[Grumpy_Guy]

At 32,000 miles I replaced the original Bridgestone Dueler H/T 685 tires on my 2023 Gladiator Sport with Goodyear Wrangler All-terrain Adventure with Kevlar …[$700 for four tires, Yeah, I’m a cheapskate…]
Both tires are 245/75R17.. New tire outside diameter is 31.7”, about .2” larger.
After a few days of driving my check engine light appeared as I pulled in to my driveway after work. It was getting dark and I decided to have a beverage and worry about it later.
the next morning the CEI was not present. After after a few more days the CEI appeared again, moving through the options I saw the left front tire TPMS was not displaying the tire pressure. I knew I had between 35-40 lbs (Florida temperatures varies in the spring, cooler and 40’s to 80’s occur through the day)
Later the CEI disappeared. I returned to the tire shop. I was told a fairy tale by the boss guy that. the TPMS battery had failed and a new TPMS was $135 plus labor.
I choose not to waste time discussing the characteristics of battery life with the “EXPERT’ and I left, weighing the probability of ever returning again.
The occurrence continued intermittently. I decided to return to a dealer for correction.
The dealer‘s service manager could not duplicate the fault, TPMS determined to be faultless and fully correct after over 90 minutes of labor (still under warranty at 32,000+ miles, no cost to me)
I still see random CEI warnings for the left front tire TPMS failure.
As an aside, with mh cruise control set at 55 mph my GPS will display my speed as 54 mph. I attribute to the great .2” outer diametrically of the new tires.

You keep saying CEL the TPMS is different when a TPMS goes bad it will change your dash screen to the tire pressure If it is a TPMS issue did they replace the valve stems with the tires? Maybe they didn’t get the sensor screw tightened or maybe cracked the sensor breaking down the tire but of course it could be a battery on its way out but usually they are not intermittent If CEL need to clarify with dealer

$135 + Labor for a new TPMs in a single tire??!! That’s nuts!!! I just paid $86 out the door for one to get put in. And that’s in SoCal!! I’m assuming they were quoting for the sender and not receiver? Check another tire shop.

I went to one Jeep Dealer, no joy, tech suggested my aftermarket radios (CB, 100 watt HF, 75 Watt UHF/VHF, and GMRS) could cause problems. I departed that "expert" and I seriously I'll visit there again.
I'm still under warranty, I visited another jeep dealer, i said replace the left front, it is intermittently functioning. I got no argument, It was replaced and I left in a Little over one Hour.
