Here is a pic of the valve stem.
Does this tell you anything?

 

That is a TPMS rubber valve stem. That extra brass shoulder is the tip off.

You tried upping the pressure on all 5, did that "cure" the warning? What pressure did you go up to?

Can't say why it took so long to register, but maybe it registers each individually one at a time and took that long to read all 5.

 

I went up to about 37 all 5 and the light and ding still come on.

 

If you're at 37 and have driven for more than 20 min. and you still get the light, you might have a faulty sensor. That will trigger a light. Spares have sensors but they won't set the light off unless they have been mounted and rolling. They then synch. to the computer and operate normally.

 

Thanks for the input everyone. I guess I'll have to swing by the dealership and see if they know what's going on.

 

Most any shop that can mount a tire will have the device to ping the sensors. At least they can tell you if there is a bad one.

 

I'm having the same problem with mine, i swapped my stock 16's for some moab 17's with stock SRA's. I had no light for about a week, then out of no where i got the light, it will blink for a little bit then stay solid. I've also brought each tire up to about 37-38 PSI and it still stays on. I haven't looked to see if they have the same valve stem as yours yet, i do know that my spare has a much longer valve stem then all the others, I did have it mounted up for alittle bit but recently swapped it to the spare when i noticed that its stem was longer.

 

At the dealership now, hopeful it's an easy(cheap) fix. If not I'll just live with the idiot light.

 

Drop it off again this morning for them to install new sensors. Just got a call, still not working. They don't know whats wrong.

 

Dang, that sucks... I pulled the TPMS out of my Rubi wheels and mounted them on my XD Monsters. Haven't had any issues with them.

Guess I will should mention no TPMS when I post them for sale...

Good luck!!
