Tire pressure monitoring??? A reliable design was first introduced with the Hummer. Basically to lower pressure and allow flotation in deep sand condition (Iraq and other suppliers of oil) High pressure can be resume to climb palatial stairs (Saddam's). Unfortunately, for civilian purpose, the sensors will tilt with a 5psi differential. Causing your ECM to display codes. Expert recommendation: send a diagram to Toyota without violating patented design!!

Reliability issues needs time to be resolved. Usually from the source it has been duplicated from: German, French, Swedish and American.

I was just told by the dealer that my 2006 Toyota Sienna AWD, which we purchased new, needs all 4 tires and brakes replaced. The van only has $14,900 miles on it. They are picking up the cost of the tires because of the issues with the RFT's, but I have to pay for the labor and the brakes plus alignment and balancing.

I basically drive it to and from my kids school and the market. I think the longest trip I ever took it on was 150 miles round trip. I love this van, but if I have to replace the tires and brakes at the next 15,000 scheduled maintenance then I am dumping it and getting the Honda!

We got this one because of the AWD, but we live in Northern CA so it's not like we have to deal with snow unless we go to Tahoe, and that is only a couple times a year.

I loved my 2006 AWD Toyota Sienna, until the problem with the run flats. My dealer has refused to replace the tires and was not helpful, and down right rude. We found out about the class action law suit, only to find out that our vehicle was not covered because the car was built a few months after the cars covered in the law suit. You would think, under the circumstances, with the ongoing problems with these tires, that Toyota would want to make their customers happy. Wrong! Do yourself a favor, stay away from the Sienna with run flats! And because of the very very very poor customer service, you would do yourself a favor to stay away from Toyota!

We are in the market for a new car and after a lot of researching and making the rounds of dealers we were converging on the AWD Toyota Sienna. It was the perfect car for us as far as features and functionality. Because of the Run Flat Tires we have now crossed the Sienna off our list and are considering our other options. If the tire issue did not exist I would now own a Sienna. Because we live in the snow belt and on a mountain we need AWD or a regular 4WD vehicle. What a disappointment. The word is spreading. How many others walked after deciding that they did not want to live with the tire issue?

I own a 2005 Sienna XLE. It came with Bridgestones. I had a flat with one and had the dickens of a time getting it fixed. One Toyota dealer in NH could not even replace it. I had to buy a brand new tire.

3 months later, my original dealer replaced all four tires (including my brand new replacement) with Dunlop tires.

Almost 2 years later, (25,000 miles) driving back from Florida, a rear tire failed. I was barely able to limp to a tire place who did not carry run flats, so I put on a regular tire.

The same day, about 200 miles up the road, the other rear tire failed! Again I was barely able to limp to a Toyota dealer who sold me a brand new run flat. I was told that my two front tires were badly worn.

I am about ready to dump the Sienna, despite otherwise liking it, over these crappy tires. I would like to replace them, but hate the thought of buying a spare and jack and carrying them in the back for the rest of my ownership.

And that is exactly the issue, in case others are reading this. There is no place to put a spare. This vehicle was designed for run-flats. Bad situation. Sorry to hear about it.

Peeling paint on the aluminum rims has been a continuing problem that Toyota has known about since the 2004 model, according to web posts I've found. The rims on my 2005 XLE AWD starting bubbling around 18 months after we bought it. I took postings of 10 other people with a similar problem to the dealership with no luck. Toyota zone rep accussed me of not washing the rims enough. Their zone reps best offer was to "give" me 2 rims if I purchased two at a cost of over $900. I have also gone through the Dunlop RF debacle. Toyota replaced four tires. Subsequently I have purchased two more - one of the initial replacements got a bubble, the other a split and failed on the highway. Neither were warranteed because they were "warranty replacements." This is the first and last Toyota I purchase.

I love my 06 AWD Sienna Van, but I hate the run flat tires. I was told that all 4 tires needed to be replaced after 23,000 miles. That was 8 months ago. Since then I have had to replace 5 tires due to the tires pulling away from the rim. The first 2 tires were replaced under warranty since I only got 3 miles down the road when the front two tires failed.

6 weeks later the front two tires failed again. This time I was on a trip and was lucky to be near a Toyota dealer ship that had two RF Ts in stock. The service department there told me my tires had been installed improperly, however they replaced the tires under warranty.

It is now 6 months later and again I have had a tire fail with it pulling away from the rim. This time my dealer informed me that the tire had hit something because there was a small scape on the side of the tire. Yes, I barely grazed a rounded curb and you could hardly see the scrape. However, the dealer and Toyota corporation said that was a road hazard and I would have to pay to replace the tire. Because I could not find a dealership or tire shop that carried RF Ts I had to be towed over 200 miles, which was quite expensive.

My advice to anyone buying a Toyota would be to think again, go elsewhere and save yourself much aggravation.

I purchased a 2006 Sienna AWD and have had the same issues with the run flat tires. The dealership was rude and did not even advise me of all the problems with these tires. I contacted one of the lawyers that settled the class action lawsuit and he was able to get Toyota to pay for four new tires. I am also experiencing the same issue with the alloy rims bubbling up and deteriorating. Toyota has denied any request to show loyalty to the customer. I'm cannot figure out how they get away with the address on their website to file a complaint "toyota_cares". Maybe it should be changed to toyotacouldgiveacr_p.
