NHTSA Complaint #11429967 — 2005 TOYOTA SIENNA

When driving the speed limit, going downhill, uphill, straight, around a curve, in the rain or dry weather, the vsc and slip/trac lights up, the abs system is activated / brakes engage. I loose complete control of the van. I can no longer steer or break. The breaks engage, but it causes the car to veer to the right. I have taken the car to the mechanic 5 times now and no codes show, even after he is able to the vehicle to repeat this behavior. It seems to happen a lot on off/on ramps. It happens mostly on highways, but it has happened on two lane roads. The vehicle is completely dangerous to drive. It has almost caused several accidents. I have replaced the Yaw sensors and had several alignments and this still happens. After a lot of research, we have found that this is actually really common in Toyota Sienna. People are saying that the bushings in the rack in pinion wear out and the entire rack and pinion system needs to be replaced. Some people have replaced the rack and pinion and claim that there is still a problem. But the majority say after the rack and pinion is replaced there is not further problems.
