Has anyone had problems with low tire pressure warning light? It came on and all tires check normal.........
I am 2 hours from a dealer so I thought I would ask around

You can reset the TPM by holding down the button on the central button bar for a few seconds. If it continues to come on without the actual tire pressure changing, have it checked out at the dealer.
I have experienced it coming on occasionally after a long drive (up and down the mountains no less) and have concluded that it is very sensitive to temperature differential and outside air pressure changes. When it came on while driving I reset it and if it would come on again shortly thereafter I would know that there is a "real" problem (has not happened yet).
I have also heard that some people have "slowly" lost air pressure over a rather short span of time (two weeks). As with cars without TPM systems: check frequently :-).

Thank you I will try to reset

I've had it come on three times. Each time I carefully checked the pressures and they were within two PSI of the correct pressure. Reset. They seem too sensitive.

I have had the light come on in the morning. Once the tires warm up or the temp outside warms up the light goes off usually within an hour. If it stays on I would check the preassure again or call the center and I am sure the will be able to advise.

YEP !
Three weeks ago I was getting ready to load up our Cabrio in the garage of our motorcoach to leave on a trip. Noted the TPM warning was on. Found a VERY large nail in the right rear tire right in the center of the tread area.
I used a motorcycle type "mushroom" plug to fix the leak. No more problems with leakage at all during this trip. We put on several hundred miles putzing around the countryside and all is well. I did remove the wheel from the car to do the plug, but probably COULD have done it without removal.
The TPM warning did work as advertised and showed the slow leak from the day before apparently. I was happy to do the fix in my own garage rather than messin with it out on the road. I might not have noted the slightly low tire when I loaded the car into the coach and tied it down.
We have never had a false indication from the TPM system, and do have over 4,000 miles on it so far.

My tire pressure lights came on after a long drive through the mountains and some time back in the city and then a change in temperature. So, I double-checked the tire pressure, noticed one was low, and then did the re-set thing (holding the button in for a while) after I was sure that all the tires were correct. No problems since then, so hope yours works OK too after re-setting.
One time, the light came on while I was driving, and it turned out that my husband had his foot up on the dash against the button! Of course, I made sure to re-set it soon after that trip.

An update since my last post. I've had it come on 4 times in the last week. Each time I get out, check the pressures, find them within 1-2 PSI of where they should be, and reset.
Attention smart HQ: This is a problem, not a solution. I'm not real keen on getting out in the dark and the rain to check my tires nearly every time I get in the car.

Attn smart HQ: My bad. The tire pressure gauge I've been using was reading approximately 4-5 PSI too low.
Today the fine crew at smart Center Seattle checked my TPMS system, and all was well. The system worked as advertised, alerting that the pressures were low. They were all about 4-5 low, and that indeed is the point where the TPMS system alerts.
Stopped and bought a new pressure gauge on the way home.

My pressure warning light came on the other night when I was coming home late. The next day the light was off and has not come back on again. But that led to my questioning what the tire pressures should be. The tires say 44 and 40 max; my salesman said to keep them at 29. When I checked them, they were at 29 and about 25, so perfectly matching that I presume my dealer filled it to that level. They ride fine but seem a bit low to me. Just what is are the suggested pressures?

Dody, the correct pressure is on the driver's door frame, on all cars. Sounds like yours were incorrectly set. Get an accurate gauge, and check and fill when the tires are cold. Mine were low, but only because I was using an inaccurate gauge.

You need to check the pressure cold, in the morning prior to driving off for example. You can make a note of what you need 3psi rf or such and then add that at the first air pump available. Just add 3 psi to the warm/hot reading and you should be good to go. Just do not let air out to get the numbers on the doorpost or you will be under inflated.
Speed ratings refer to how well a tire sheds heat from use a W rated tire will take much longer to get to operating temp than a Q for example and is why "snows" are important in cold weather regardless of snow being on the ground. Under inflate heat builds faster, over inflate and they may not get to operating temperature. "Life used to be so simple..."
