Tire Pressure Light On Problems of Toyota Sienna

I took my car in for an oil change and asked them to check my tires due to my pressure light being on and the car was driving funny. Upon inspection it was discovered that there was a busted belt in the sidewall. This is the second tire I have had to replace in two months. Also, it was stated at this time that my car will not pass inspection due to wear on the tread and I will need to buy new tires before re-registering my vehicle. Car is less than one year old with under 20,000 miles.

We bought a van on 9/05/08 on 9/13/08 low pressure light came on checked my tire there was a bulge on the edge of the front drivers side tire that pulled it away from the rim dealership said it was a road hazard, and would not replace it. Van had approximately 18500 miles on it. We had to pay $136. 00 for another tire. Today 9/26 I had to travel 50+ miles with my two babies and 3 older kids in the van and a bulge appeared on the back drivers side tire in the exact same place as the other tire that did it just a little over a week ago. This time the van had approximately 19424 miles on it this is not a road hazard!!!! it has to be a defect and no one is listening. The dealership said they put 4 brand new tires on the van before we bought it.

I bought my 2008 Toyota Sienna in October 2007. The first defect I noticed is when the rear windows are open, the rear doors do not lock in place when you open them. The mechanic stated said the he thought the reason it was designed this way was as a precaution, in case a child is leaning out of the window when the doors are opened. This made no sense. My experience has been that the door slams really hard and then bounces back. If a child happened to be leaning out the window they would suffer serious injury because of this. No one has been injured thus far, but the slamming certainly startles everyone! this happens even if the window is only open slightly. Another defect is the tire pressure light on the dash. It stays lit up constantly. After adding air on numerous occasions, I noticed that the light comes back on in just a couple of days. I discussed this with the dealer and he simply stated that tire pressure changes with the temperature. This is a safety issue because I would not know if the tires' inflation was really off or not. Obviously I cannot add air to the tires every other day.

I have concern with tires and low pressure light illumination . I had 15k service at dealer on July 22, 2006 with 15,423 mileage and they said the tire wear pattern for four tires is ok. Also dealer adjusted, inspected and rotated the tires at that time. But during 2,000 miles drives after service, the low pressure light was keep coming on even though I kept the proper pressure in them. So I went to firestone for check up and they informed me that I need new rear tires. I went to costco for 2nd opinion on November 22, 2006 with 17,647 mileages and they informed me that I need two new rear tires due to worn out. I was pretty upset at unusual rapid worn out right after manufacturers recommended 15k service. I send the letters to Toyota but they don't even send a reply letter.

Tire pressure warning system on my 2005 Sienna awd (13,000 miles) turned on. Checked pressure in all tires, left rear was below 15 psi, all others were 25 psi (recommended pressure is nte 51 psi). Filled tire to specification tire pressure and light rescinded. Within 5 days, light reappeared with same procedures and results. Took to the dealer. Dealer replaced single tire indicating a nail was found. Within 30 miles, the replacement tire deflated (dunlop, oem run flat tires) on freeway. No tire pressure warning system light illuminated. Air pressure was checked and did not register any pressure, assume 0 psi. Triggered to check tire pressure after hearing a loud popping sound. Tire pressure warning system is not operating as expected and dealer indicates there is nothing wrong and "that's just how the system works". Remaining dunlop oem run flat tires do not retain pressure greater than 25 psi. Dealer says they retain pressure when monitored there. But within 5 days, pressure returns to 25 psi.

1. Run-flat tires get flat significantly more often than regular tires. 2. The low pressure light does not always go on when the tire is flat and off when the tire is not flat. 3. The tires get worn out after around 12k highway miles and are expensive to replace. 4. Most of the shops do not have the equipment to handle the tires. Specialized places have to wait long to order the tires.

I purchased a 2004 Sienna brand new in 2004. Toyota engineered the 2004 Toyota Sienna w/ dunlop run flat tires. As such they designed no space for a spare or a jack. Including 4 tires that were replaced as part of a recall I have replaced a total of 13 tires in 6 years. These tires cost almost $300 to replace. The low tire pressure warning light has never lit up, Toyota tested it and stated it works but have no idea why it does not light up when the tire goes flat. Toyota takes no responsibility for their design choice in any way. I have requested everything from partial reimbursement to a full set of regular tires with a spare and a jack. All requests have been refused.
