I UNDERSTAND THAT FEDERAL LAW NOW REQUIRES ALL NEW CARS TO HAVE TIRE PRESSURE MONITORING SYSTEMS. I WOULD LIKE TO COMPLAIN THAT MANY OF THESE SYSTEMS ARE SO SENSITIVE THAT THEY WILL BE EFFECTIVELY USELESS BECAUSE DRIVERS WILL IGNORE THEM. I HAVE ALWAYS BEEN RELIGIOUS ABOUT REGULAR MAINTENANCE, INCLUDING CHECKING MY TIRE PRESSURE REGULARLY. MY 2009 NISSAN VERSA'S TIRE "IDIOT LIGHT" IS ALMOST ALWAYS ON. IT TAKES AS LITTLE AS 1/3 LB. CHANGE FROM THE RECOMMENDED PRESSURE FOR THE LIGHT TO COME ON -- SOMETIMES IT COMES ON WHILE I'M DRIVING AND IS OFF AGAIN BY THE TIME I FINISH MY TRIP. CONSULTING WITH BOTH DEALERS AND OTHER OWNERS OF NEW CARS CONFIRMS MY SUSPICION THAT THE SENSORS ARE JUST TOO SENSITIVE -- SOME HAVE REPLACED ALL THEIR SENSORS TWO OR THREE TIMES TO NO EFFECT. I JUST WANTED TO MAKE SOMEONE AWARE THAT THESE DEVICES, WHILE A GOOD IDEA IN PRINCIPAL, ARE JUST TOO SENSITIVE (AND ANNOYING) RIGHT NOW FOR THEM TO BE USEFUL SAFETY DEVICES. THANK YOU. *TR
