Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Need solution to fix it.It is very dangerous for it to kick in and cause a accident. Especially when driving in a winding road,and causing the van to go on a ditch.Need a solution to fix especially if it's a defect it should be free,and Toyota should send a recall notice to fix this problem.Thanks

Sienna LX

  • Automatic transmission
  • 86,000 miles

Check engine light came on after a tire rotation. Scan shows p0018. Changed sensors to no avail. Many people reported problem. So far no one reported what fixed the problem. Do no want to go to dealer because they charge too much. Even after paying a lot for the vehicle.

Sienna LE 3.3L V6

  • Automatic transmission
  • 126,000 miles

Recently, I was driving about 60 mph when suddenly the SRS light starting beeping and my car lost acceleration. Because of this it caused everyone in the vehicle to jerk forward and the engine appeared to be stalling. As it was a very scary situation, I immediately pulled to the side of the rode where my check engine, VSC, and TRAC off indicators were all lit. After leaving the vehicle off for approx. 15 minutes, when I turned it on all indicators were off and the vehicle operated as normal. I took it to the Toyota dealer the next day where they could not find the source of the problem.

Sienna XLE V6

  • Automatic transmission
  • 67,000 miles

The check engine, VSC, and TRAC lights all came on at once. Turned out to be the yaw rate sensor going bad, which was a very expensive fix because of the intensive labor it took to get to it and replace it. 14 months later, the same lights came on. The previous work was just barely out of warranty, so there goes another thousand bucks down the drain on this stupid car. I will never buy another Sienna.
