Driving 35-55 mph and going around (usually) a left curve on the highway or interstate, van suddenly brakes, swerves, and traction control/vehicle stability control light pops on. Whole episode lasts a second or two, then its fine. It wont happen again for the duration of the trip. I only drive the van on weekends, and it has happened three times in the past two weeks. It has nearly caused a serious accident.

While driving in the mountains and curving right, the stability control activated the brakes. The car was not speeding and the roads were dry. It happened 3 times in one trip. The braking action made it difficult to complete the turn. Plus the decrease in speed was a danger to the occupants plus the car behind us. Other curves did not activate the stability control so it was a guess as to when and if this would happen. Did make it back safely.

The vehicle was stationary and one day ABS malfunction light came on due to faulty harness on a 3 year old 35,000 mile vehicle. This reduces the ability of the vehicle to stop normally as it should this also disables the traction control on the vehicle. I was driving in rain without any traction control and it was scary. I contacted Toyota and they keep stating the car is out of warranty. It is $500+ repair to ABS system due to their faulty parts. I just need this to be on the record incase something happens while driving a Toyota Sienna.

I have a brand new Toyota Sienna and the tires seem to start showing sign of wearing off in 6 months, as if it has alignment issues or something. The car does not pull to one side or anything. The dealership told me that it could be the tire pressure that needs to be kept up and they said that the tire pressure indicator is not good enough to make sure if the pressure is good" also they told me that the tires these days are softer so they don't last as long" this all seems a little hard for me to believe. Oem tire warranty up to 60K but not last long. Just change new sets of tire with alignment. Toyota engineering needs to address this issue
