This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
Tire pressure monitoring system is not working and Toyota has made up various excuses as to why the light does not go off during a flat or "blow out" or that it is working properly. Recently I was extremely nervous during driving and found after pulling off and stopping at a Honda dealership that I had an undriveable tire. Honda was not sure why the light did not go on but said it was unsafe to drive and would not hold air so I could not get to Toyota. Beside the 9 tires I have replaced the latest tire cost me a rim also. I am assuming that this was due to the flat that I did not know that I had. Something needs to be done about the run flats and especially the tire pressure monitoring system before someone is killed or severely injured. Please do something about this very serious problem.
The contact owns a 2004 Toyota Sienna. The TPMS does not alert him when the tires have low pressure or if they are about to fail. The vehicle was taken to the dealer for inspection. The technician could not duplicate the failure, therefore they could not provide a remedy. The manufacturer was notified, but no assistance was provided. The failure mileage was 60,000. The current mileage was 69,000. Updated 10/23/09 the consumer stated the tire pressure warning system did not alert them that there was a tire failure. The tire shredded while driving 65 mph. The second occurrence, the consumer ran over an object in the road, and once again the tire pressure system didn't detect a failure. Updated 10/27/09.
"clunking" noise noted on steering the 2004 Toyota Sienna just a few months after it was bought. It had gone through 3 recalls already when first the fuel tank, then the door sills, then the middle row seatbelt bezel, and finally recently, the rear hatch struts were all replaced. Vehicle was test driven, but no mention of "clunking" documented. However, all this time, the clunking had become more noticeable, and vehicle had gone through 2 alignments already, with only about 42,000 miles on it. Last serviced for alignment, dealer did note clunking and recommended replacement of intermediate steering shaft. It is now becoming more difficult to steer the vehicle, especially at low speeds, and "K-turns" now require more maneuvers, and the steering radius has increased potentially causing collisions with objects or pedestrians if compensatory action is not initiated. (steering output has sometimes been unpredictable). Second component is lack of TPMS sensors when tires were changed at a facility, and I had the facility document the lack of sensors.
From the time we purchased the car we have had many problems with our Bridgestone run flat tires. The sensor on the dashboard was constantly on, so we had to check the tire pressure every week- what a pain! the dealer was no help, they agreed that they have had many problems with the tires. We finally decided to replace them with standard tires and I drive without a spare. I figure I'll call aaa if I have a problem.
Toyota pre-2007 TPMS (tire pressure monitoring system) design flaw. It only works when you "suddenly lose pressure" while vehicle is moving above 20 mph. It does not detect tire pressure loss any other time, even if one tire is at zero psi and you start driving, or if you hit a nail at a red light and tire pressure went to zero before the light turned green when you start moving again. Compounded with run-flat tires, the driver may never know they have a flat until the tire explodes.
Tire pressure monitoring system does not work. Three times in the last 2 years I found zero tire pressure in one of the tires on our 2004 Toyota Sienna xle AWD and the tire pressure monitoring system gave absolutely no warning. Reporting it to 2 different Toyota dealers, they said nothing is wrong.
Regarding NHTSA action no. PE06010, I have a 2004 Toyota Sienna xle limited with AWD with the tire pressure warning system (tpws) for my dunlop run flat tires (sp 4000). I have experienced punctures in two of my tires on separate occasions. Both times the tpws only activated when the psi was about 5- to 15. The dealer indicated to me that the magnetic system will only activate once a tire's height becomes lower due to air loss, and the magnetic field is "tripped". the problem is that the run flat tires do not lose their height due to air loss until the tire is nearly depleted. So, the tpws essentially cannot properly function as intended, at least when run flat tires are installed. As to the dunlop run flats, they had to be replaced after only 19,700 miles. I know numerous other consumers have had similar experiences. Toyota acknowledged the problem and relpaced my tires with a new set of 4 run flats at no charge (other than installation). Typical price is $250 per tire. Credit to toyata, but not sure what will happen when the new set fails.
Our 2004 Toyota Sienna xle has a low tire pressure indicator that appears to not work. We have personally let all but 10 lbs of air out of one of the tires and the light still does not go on. Repeated attempts (3 as of this date) to have the dealer fix the problem have resulted in "opinion" from the dealership and no solution. We have asked for the sensor to be replaced, and the computer to be replaced to no avail. We are unsure that our vehicle is providing the level of safety that we assumed when we bought it. The latest statement from the dealer is that the car "...needs to be driven at least 50 miles in the low pressure condition for it to work properly". this does not make sense to us. Are we expected to endanger the safety, and lives, of our children, by driving around for unreasonable distances in an unsafe condition for the vehicle's "safety" features to work?
2004 Toyota Sienna equipped with run flat tires. Had tires put on by Toyota on Friday Oct. 28. Sunday Oct. 30 while driving on highway had a tire blowout causing $2226 damage to car. Pressure warning system did not work or was not set by Toyota when tires were mounted on Friday. If the pressure warning had been working we would have known there was a problem with the tire and had it fixed. Not knowing there was a problem with the tire led to the tire blowing out. Had van towed back to Toyota and explained what had happened and they basically told us we had run over something and that we were going to pay for damage. Toyota was unwilling to acknowledge any responsibility in this matter.
Tire pressure monitor not functioning properly- multiple times concerns of blowout. Premature/uneven tire wear on run flat tires. Self monitoring of air pressure and replacement of tires.
On 06/09/2005, we noticed that our 2004 Toyota Sienna AWD-xle had a flat tire on the driver's side rear. The tire was noticeably flat and we limped to a service station to inflate the tire. The tire had zero tire pressure and a massive hole between the treads where you could feel/hear the air escaping as it was being filled. The tire had 0 psi/tire pressure. The dunlop sp sport 4000 run-flat tires came standard on our 2004 Sienna. We went to the dealership where we purchased the vehicle, have had service completed and tires rotated as required. Our van is 10 months old and has 13,800 highway miles. The dealership said they did not have the matching tire in stock and would work to find one. The assistant store manager said they had not seen any run-flats with flats. Later that day, the dealership called and said they had a deal for me. They were able to get the Toyota rep to give us 4 brand new tires for free, except they needed to keep the vehicle the weekend until the tires arrived. When asked why? and if there was a problem with the other tires, I was told that they had worn down to a level that would barely pass a New York state inspection. After doing some research on-line, it is clear that the 2004 Toyota Sienna AWD-xle and other versions, are in serious jeapordy due to tire failure. The vehicle had been driven for a day, in excess of 50 mph, without knowledge of the catastophic tire failure on the run-flats, and there was no indicator light ever activated. The dealership will be getting a print out of this website's related search results and Toyota will be contacted for a complaint. We realize we are fortunate to get 4 new tires at no charge, but the issue is safety, not appeasement. Please help.
Have a toyata xle AWD van with run flats and tire pressure monitoring system. The tire pressure monitoring does not work. Front passenger tire has a leak which could not be found 2 weeks ago. The system was reset, all tires pressured up by the dealer 2 weeks ago. There is a 20 psi difference between the left and right wheels and the system does not light up in the dash. 3 week ago, we went on a 2000 mile trip, before which I noticed the problem of one tire being low in tire pressure and the system not working. The dealer has no fix on the problem and said Toyota does not have any tsb's on it. Now duse to this defective system, they have found a leak which may be close to the sidewall on the tire and cannot be repaired and it being an all wheel drive vehicle, I am being advised to put 4 new runflats at over $1200 with less than 16000 miles on this vehicle.
