My tire pressure monitoring system keeps turning on regardless of whether tire pressure gauges or mechanics say the tire pressure is within range. I know this system had a recall on other model years for Toyota, and I think there's something wrong with this one, too. This is an ongoing problem since I bought the car used from a Toyota dealership--unknown if it was an issue before then. Resetting the system (by pressing the reset button to the left of the steering wheel, as indicated in the user manual) only turns the light off for a minute or two, then it comes right back on.

This is an update for the complaint regarding the failure of the tire pressure monitoring system on my 2005 Toyota Rav4. After finding a knowledgeable service manager who took the time to check, he found that there is a tire pressure sensor in the spare tire. My spare was just a little low on air and since correcting it, the light has not come on again. I was not able to find any reference to the spare having a sensor in the owner's manual.

The tire pressure light comes on just about every other day. I have had the tires checked numerous times & the light continues to come on, this has been happening since November of 2007. This is a serious safety issue, I will never know if there is a real problem with a tire with this happening. I drive the highway daily & find this very troublesome. My 2005 rav 4 has under 25,000 miles on it. I am estimating the number of failures to be 50, however I think it is more. I believe this is a defect & Toyota should require these to be recalled & fixed.

The tire pressure light fails constantly and without reason. I've had my tires checked, rechecked, balanced, rotated, rebalanced, rotated again, and nothing will stop the light from coming on. There are only 20,521 miles on my Rav4. This problem has been going on for months. I took my Rav4 to my mechanic again this morning and after checking all the tires again, he found no problems. My tires are new, less than two months old. While taking my husband to the hospital today the light came on again. My mechanic says it's a defect that the manufacturer should fix.

When roads are icy or snowy, TPMS warns that tire(s) is low despite all tires having the proper pressure. After confirming adequate tire pressures, I reset the system. After encountering snowy/icy roads again, the TPMS alerts again. This false alarm would likely confuse most drivers.
