One problem related to tire pressure monitoring system has been reported for the 1998 Toyota Sienna. The most recently reported issues are listed below.
Aluminum alloy rims apparently expand and contract with temperature changes, causing leaks in tires. Sometimes pressure drops 2-3 lbs. But sometimes it drops to dangerous levels (15 lbs. Or even less). Sometimes the tire pressure monitor alerts and some times it does not, even at dangerous low levels.
