I have had ZERO problems with mine and they have been swapped twice into different wheels.

The superchip programmer lets you set your own warning light pressure which I know could help some folks.

 

i put on new wheels and tires on my 2010 and it took 350 miles to even come on. i ran without tpms in spare for about 1 week then about a week without all of them before it came on. if it takes that long i don't need it. just another gadget to mess up. good luck tho and to each his own on the tpms but for me there just junk.

 

It definitely has to do with cold weather for mine, but it does not do it all the time. When the temps drop down to the low 40s, mine has lit up, but shuts off after I have driven a few miles.
