...is on for no apparent reason. The warning light looks like a cross section of a tire, with an exclamation mark (!) inside it. I have not touched the tires...and the truck is only 3 weeks old. The tires look inflated properly....but I guess I will check the pressure just in case.

 

There's a thought...
My dad's Grand Cherokee did that and I looked at the tires and said "no way." He checked and found that it had a leak.

 

We have tire pressure warning light?

 

i know i see it on my guage cluster when the sun hits it just right... but the actual monitoring system i beleive is only on the 2008 models

 

mine did that after 1 week... everything looked good, drove correct... bought a new pressure guage, checked them out and one was down to 25psi... next day light comes on again. tire shop removed a nail.

good luck!
