does anyones low tire pressure indicator come on in the winter season, because i checked the pressure and everything and its perfectly fine!!!!

 

I have the same problem...and it is very annoying. I've actually checked into the recalls, and I have not found anything... I did find a TSB regarding the problem. I need to make an appointment with my Lexus dealer to take a look at the problem.

Here is a link to the TSB...

LETS SEE IF I CAN HELP YOU OUT. IN THE WINTER THE COLD WEATHER DROPS THE TEMPERATURE AND THEREFORE PRESSRE OF YOUR TIRES. SO THE LIGHT WILL COME ONUSUALLY UNTIL YOU DRIVE THE VEHICLE FOR A WHILE. IF YOUR LEXUS IS FAIRLY NEW IT CAN BE THAT THE THRESHOLDS FOR YOUR TIRE PRESSURE SENSORS WERE SET TOO HIGH. WHEN INSTALLED AT THE FACTORY, THE TIRES WERE PUMPED TO ABOUT 50 PSI TO PREVENT DAMAGE DURING TRANSPORT SO UR SENSOR NOW LOWERED TO 35 STILL KEPT THE OLD THRESHOLD. THE DEALER CAN REINITIALIZE THE SENSORS FOR YOU OR YOU CAN DO IT AT HOME. THE SENSOR THRESHOLD WILL SET TO 20% OF THE PRESSURE IN THE TIRE WHEN YOU RESET IT. SO PUT YOUR TIRES TO ABOUT 30PSI THEN HOLD THE RESET BUTTON UNTIL IT BLINKS THREE TIMES. THE LIGHT WILL REMAIN ON BUT NOW THE SENSOR WILL LEARN. THEN SET YOUR TIRES TO 35 AND YOUR NEW THRESHOLD WILL BE 20% OF THE INITIAL 30PSI, SO ABOUT 26PSI.
