While driving on dry freeway or other stable road conditions, the Electronic Stability Control kicks in, braked hard, causing the van to swerve, and the lights on the dash started flashing, accompanied by a loud beeping. This has happened multiple times now. There is no reason for this to be occurring. It is involuntary, sudden, and random. If someone were close behind me, they could rear-end the vehicle. It also sometimes pulls the steering so hard that it swerves into the other lane. This is a serious safety issue that Toyota needs to deal with.

The vsc system is enabling while driving and making a turn on an otherwise normal road. When it enables, it applies the brake and sounds a repeating alarm. The system applies the brake while I am attempting to make a turn, and this makes me feel unsafe, as if I have temporarily lost control of the vehicle while making an otherwise benign maneuver. The repeating alarm does not turn off until I have turned the wheel to the opposite direction from the initial turn angle. This means if the turn is slow, the alarm will sound for the entire distance of the turn.

The side doors have a button you can push for them to open. I went to open and shut my daughter door and it would not shut after looking it over the wire that comes in and out for the doors to shut got stuck in the o part that the cord retracts to.because of this my door would not close manually or automatic pushing the button. I am also having problems with the control panel where the fuses are under the hood. One fuse gets fixed another one breaks. I have confirmed this with a auto shop the problem is within the control panel.

I am having a massive problem with my vsc. Randomly, regardless of speeds (it's happened going 70 as well as 25, and 40 MPH), my vsc will kick on, kill my speed, and cause me to swerve. As you can imagine, going 70 on an interstate with other vehicles around and having this happen is life threatening not only to me and my family but other vehicles around me. Reading on several auto forums, this problem has been drawn to the attention of toyota corporate to no avail. It is absolutely beyond me that they see no reason to file a recall.
