2 Tank Assembly problem of the 2007 Toyota Sienna

Failure Date: 02/15/2010

My 2007 Toyota Sienna has an average mpg readout. I reset the readout when I refill the fuel tank. When I have about 177 miles on the tank, the mpg reading instantaneously drops about . 3 or . 4 mpg. I reported this problem to the mark miller Toyota dealership and they had no interest in it and refused to pursue the issue. This problem is highly repeatable and occurs each time the above sequence occurs. I report this because on the news a couple of days ago, the Toyota ceo reported that they had no reported computer errors on their products. I had reported what I suspect to be a computer error and Toyota didn't appear to record the report.

4 Tank Assembly problem of the 2000 Toyota Sienna

Failure Date: 05/27/2005

Following an accident where I was rear ended I started having problems filling the fuel tank. The pump would click off as if it was full at . 70 cents and would continue this while filling the tank when the tank was clearly empty. I was advised by several people to move the handle around while filling this did not help. It was inspected by the body shop who said they could find nothing wrong & advised me to take it to the dealer. The filling problem continued & actually got worse & was taking longer & longer to fill. Today I went to fill it got to about 2 1/2 gallons and fuel started coming out of the tank as if I overfilled it. I tried to fill it again it did the same thing every time. Also quite a bit of fuel spilled out on each attempt.

5 Tank Assembly problem of the 2004 Toyota Sienna

Failure Date: 10/19/2004

Attempted to start our 2004 Toyota sienne van in the driveway of our home. The van died immediately after starting and could not be restarted after several attempts. My wife removed our 3 and 4 year olds who were strapped in the third row and used another vehicle to get them to school. Returned an hour later with a friend who was going to help start car. While attempting to start the van, a strong odor of gasoline was smelled and it was discovered there was a massive gas leak and gasoline was pouring out from under the van. Atempts to start the vehicle were stopped immediately. The van was towed to windward Toyota in kaneohe, hawaii. The service technician who inspected the van told my wife the service technician who did the gas tank/fuel line during the recall warranty service did not reattach the gas line to the tank properly probably since they were rushing to perform recall warranty service on many vehicles. This was the second van at this dealership he knew of being serviced for the exact same problem. His explanation was unacceptable and we decided to review NHTSA website. Upon reviewing complaints on NHTSA website, we discovered there were 9 other reported incidents involving massive gas line/tank failure. We found this alarming since we reviewed over 100 comlaints filed on the 03 Sienna,and 04 rav, sequoia, tundra, and 4runner. No other vehicle reported any fuel tanl/line problems. A fuel leakage problem can have catasrophic results especially since young children in car seats are often in the third row. We no longer feel safe owning and driving this van and want Toyota to purchase van back from us.

7 Tank Assembly problem of the 2004 Toyota Sienna

Failure Date: 05/01/2004

"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.
