  • 80,000 miles


The contact owns a 2005 Toyota Sienna. The contact stated that he experienced a blow out on one of the tires. The contact was concerned because the tire pressure warning light had not indicated an issue with the tires. The contact installed new tires and allowed the tires to be filled with less air than recommended. The tire pressure warning indicator still did not indicate a low pressure warning.the vehicle was taken to the dealer and they advised that the tire pressure sensor could not be inspected or repaired. The manufacture was not contacted. The failure mileage was 80,000 and the current mileage was 83,000.

Regarding 2005 Toyota Sienna investigation PE06010 tires: Pressure monitoring and regulating systems which is "closed", I have experienced this twice. Two flat tires, with dunlap run flats, both tires severely damaged by running without enough pressure, no warning lite came on. Scary to think you can drive at freeway speeds and not know you have a flat, but when you exit the car and happen to notice the flat you feel lucky not to have crashed. Toyota dealer says this is just the run flats doing their job. I had two sets of these run flats and have switched to standard radials and feel safer, at least I will know when I have a flat tire while driving! sorry I don't have the tire/model size info in front of me now but I can look at receipts for further details. I know it was sport something, and 17". the dunlaps went to recycling so I don't have their serial numbers.

We have a 2005 Toyota Sienna with all wheel drive (AWD) and run-flat tires. The right rear tire disintegrated while on I80 at freeway speed. There was no warning by the tire pressure monitoring system, before or after the tire failure. I noticed a vibration earlier in the day and now suspect the tire had been flat for some miles. This was our second instance of a failure of a run-flat tire, but in the case of the left front tire, the warning light did come on. In both cases, it was necessary to replace all 4 tires due to the AWD. In both cases an alignment has also been done, which includes resetting the speed sensors (tsb PG005-04), and no problems were detected. This indicates the system is inadequate to reliably detect a flat tire and a crash could have easily resulted.

I have a 2005 Toyota Sienna with all wheel drive and run-flat tires. I was told that the car has a tire pressure monitoring system (TPMS). I had two events of low tire pressure that went undetected by me. Both times I took the car to the dealer who told me the noise and vibration was due to low tire pressure. I told them that I never saw the low tire pressure light on the dashboard. The latest event was a blow-out of the left front run-flat tire on hwy 85 in ca. The car was difficult to handle and I slowed and exited the freeway and there was never a TPMS warning light on the dashboard to indicate loss of tire pressure. The tire was totally gone. Had to cover the cost of that repair. I recently took the car back to the dealer to find out why the TPMS was not working. The dealer then told me that the TPMS system on the 2005 Toyota is based on the anti-lock braking system and uses the speed of tire rotation and not direct tire pressure measurements. Furthermore, they told me that the tmps was working perfectly. I find application of a tmps based on tire circumference with run-flat tires is completely useless. There is no way the 2005 Toyota Sienna tmps will ever work with run-flat tires. The run-flat tires have extremely strong side-walls to allow the car to continue with little air pressure but, that means the tire does not deform with low tire pressure. The fact that I had a total tire blowout without a tmps warning light showing means the tmps system does not work. I find this system to be unsafe and I want to know what is being done and how could this tmps system comply with department of transportation rule cfr citation: 49 cfr parts 571 and 590; docket id: NHTSA 2000-8572, rin id 2127-A133?

2005 Toyota Sienna xle limited, AWD, VIN [xxx], tire pressure warning system does not work, and never has worked properly. It most recently failed on March 28, 2008, where the right rear tire had zero air pressure. This was a brand new run flat tire which went flat immediately after installation. The vehicle was driven 31miles and the tire pressure warning light never came on. Due to this faulty warning system, a brand new $250+ tire was destroyed, requiring replacement. This system has failed numerous times prior to the above-mentioned incident. Since purchasing this vehicle, I have learned that this tire pressure warning system does not monitor the tire pressure at all; that it only monitors the wheel speed, and it is extremely inaccurate at that. I have discovered that Toyota had been aware of this problem for years and yet still fraudulently marketed this system as viable tire pressure warning system on the 2005 Toyota Sienna. As a disabled person, this tire pressure warning system was the deciding factor in my buying the 2005 Toyota Sienna. I have difficulty bending down to take the tire pressures and I expected and rely on this tire pressure warning system to warn me of low tire pressure; it is a total and complete failure in that regard.

Tire went completely flat on my 2005 sienne xle limited before the tire pressure warning light went on. The low tire pressure warning system failed and despite the fact that it had "run flat" tires, I did not get the expect 50 miles of driving to get to a service station and needed to be towed.

The tires on our 2005 Toyota Sienna minivan have failed twice: Once in April 2006 and again in January 2007. Both times the low tire pressure indicator did not work. We warned Toyota the first time the sensor didn't work and they checked it and said it was working fine. Our tires failed again, and the indicator did not light this past time as well. Toyota has said we may have to pay for this latest set of tires.

Major safety problem with tire air pressure system. Normal tire pressure is 35 psi. Because of the tire design, you can run with very low air pressure and not feel it (on a normal car, it is very obvious). That is why Toyota had to put in the tire pressure warning system/light. Twice the tire pressure warning system did not come on until a tire had ~10 psi. That is a dangerous level. The first time I did nothing and the tire was replaced by the tire manufacturer (nail issue) and the tire was less then 7 months old. The second time, I brought it to the dealer. They tested two ways: 1) on the computer and it passed; 2) test drive where alert light came on below 18 psi. In my testing it came on between 10-15 psi and in real life closer to 10-11 psi (based on my 2 problems). Checking tire pressure daily does not help because in real life, if you take a trip you can drive for 3-6 hours which if something happens to the tire during the trip, you will not know until it fails (again this is because unlike normal tires, you can not tell the tire has lost significant air pressure. You can read here and other places about the catastrophic failures others have had in just this situation. I spent many many hours on the phone with Toyota to get the specification on when the system should alert you. I was once told it is a difference of more then 5 psi. However, it seems that Toyota has no published spec for how the system should work in real life. This is defective and Toyota is not telling us the truth. All systems have to be designed to a spec. This system was and there is somewhere at Toyota a spec. They are not sharing with consumers because of the implication it would have (they will have to recall/fix them). I do hope someone at the NHTSA will pursue this since it is a safety issue for families.

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.

Catastrophic tire failure on a Toyota Sienna AWD van with run flat tires. Fortunately, no major injuries or damage this time. The tire pressure monitoring system failed to sense the lack of pressure in one of the tires. Driving on the tire with no air pressure caused catastrophic tire failure. I was told by the Toyota dealer the tire pressure monitoring did not malfunction, it simply does not work. It cannot be fixed since Toyota says there is nothing wrong.

2005 Sienna AWD. Had a flat tire for a couple of days but did not notice it (only drove in town, not interstate speeds). The warning light appeared but disappeared, and then it was intermittent (it looked like it would turn on only after some driving.) luckily this did not damage the tires, but I wonder what would have happen if I were on the interstate in the middle of nowhere and experienced the same problem (no warning light). I see that a recall may be in progress.

Consumer passenger side rear tire deflated while driving. There were no warning lights, dealer informed consumer that there would be a warning light shown if pressure dropped to 5%. the warning light didn't illuminate to let the consumer know the tire had went flat. The consumer was informed the sensor was tied into the ABS.

I have a 2005 Toyota Sienna AWD that is equipped with Bridgestone run-flat tires. I was given no spare tire with my vehicle. I was traveling with my family on October 14 2005 on interstate 5 in ca. At 4 am when my tire went flat at 70 mph. The low tire pressure warning system failed to notify my wife who was driving that the tire had lost air pressure. She continued to drive until the tire started to disintegrate and she felt the vehicle start to pull to the right. There we were stuck in the middle of nowhere with a destroyed tire and no spare. I was forced to have my van towed to bakersfield ca. And have the tire replaced with a standard tire since the run-flats are impossible to find. Toyota refuses to compensate me in any way for this irresponsible design they have on their AWD Siennas. I don't want these unsafe tires on my van and I want a spare. I paid $40,000 for this van and should have been given a spare tire. I was led to believe that these garbage tires would take the place of a spare which they obviously do not!

After only 19,000 miles of use, the run-flat tires on my Toyota Sienna have been worn away significantly to a dangerous level. The dealer has recommended only replacement with the same exact tire model, as no other tire brand or model may be used with this vehicle. At only 6,000 miles one tire had failed spontaneously without triggering the low-pressure warning system. I had been told by dealer the non-visible edge of tire (side facing toward the vehicle) had worn through the tread completely. That tire was replaced at my cost, assuming it was a unique and isolated incident. I see now that these tires are inadequate.

2005 Toyota Sienna limited minivan. Came with runflat tires (no option) and tire pressure measuring system. Problem is that even with complete flat (0 psi) the system is not informing the driver. Since the tires are run flat they look no different and my wife is driving around at highway speeds with a dangerous tire and no way to know it. Toyotas response is to check tire pressure regularly. Well that's fine, but still if you get a flat and drive all the way home on the interstate at 65+ mph it's not within the ratings on the tire which says specifically not to run the runflat tires over 55mph. On top of that we have one tire almost worn out already due to running low on pressure. Multiple complaints like this are noted on internet web sites - Toyota needs to issue a recall and fix this problem as many of us with young children bought this vehicle in large part for safety reasons and it is not safe! the tire pressure system is defective, and does not work at all. Toyota is unwilling to fix it and so help me if anything ever happens I'll see them in court.
