I have a 08 ISAWD and for some reason every time the temperature drops to the mid 30's or lower the damm low tire pressure light goes on. One it warms up, it goes away. Anyone else have this problem? Perhaps I should have the dealer look at it. Also, after a small snow storm the other day, two of my windows would not open for 2 days. Maybe some ice was stuck someplace......

There's probably nothing wrong with the tire pressure sensor on your car. Your tire pressure will change over time, particularly when it gets colder your tire pressure will decrease, causing the light to go off. As you drive the car and heat the tire up, the pressures increase, which is probably increasing the pressure above the threshold for the sensor to indicate a warning.

That doesn't mean the problem (low tire pressure) isn't there anymore because you should check your tire pressure cold and adjust accordingly. Inflate the tires to the specified pressure in the doorjamb when cold and check them every month or so - you should do this with any car - but particularly after a siginificant change in outside temps

With respect to the windows, not sure but you may be right, if the windows iced over, it may have kept the window from moving. I think the most important thing to do there is to not keep the button depressed if the window won't move, you'll burn the motor out. If it happens again without ice being a possible culprit, I'd have the dealer look at it

Look in your driver door frame for the tire pressure sticker. Set the tires to the recommended PSI when cold. That will solve tire pressure light. Pressure changes about 1 PSI per 10 degrees temp change. I check mine going into summer and then in the fall going into winter minimum.

I don't have your problems on my 06 AWD and i'm in NY, but I usually keep my tires inflated slightly above what is recommended

most likely ur car was frozen due to the storm. do you park it in a garage or outside? Do you cover your car? just put more air in ur tires and the next time your window is frozen use a fan heater to melt the ice that is jamming the window mechanism from moving. it happen to me but was fixed in 5 minutes. i garage and cover my car.

Could be you're tire pressure is a bit low compared to the initial pressure setting, and the drop in temperature is enough to put you over the warning threshold. After checking tire pressure, you could set the initial tire pressure again to see if that helps. Good luck!

It is normal for tire pressure to change as the outside temps change. Get a pressure gauge and test the pressure when the tires are cold.

Put a little extra air in your tires. Mine was doing that too, because when it gets cold out you lose some pressure, so its too low to begin with if its triggering it as soon as its cold out. I put 2-3psi extra in there and it stopped doing it completely.

When you set the cold tire pressure it is also recommended to define the normal pressure by holding down the button to the left of the steering wheel in the TPMS mode.

Read the FM to get a better idea how the system works. You should check your tire pressure more often. FWIW.
