When making a left turn vehicle continues to turn left unless manually turning steering back to right, and clicking is heard.
The van has a problem with sticky return-to-center after 90 degree left turn. Tends to happen if speed is above 20 miles per hour during turn. Require jerking or swerving to return to center after a left turn. My wife thought I was swerving since the car was swaying but I was just trying to prevent us from making a full circle to the left. The sticking problem happens irrespective of road condition. I have reported it to the dealer, who checked the fluid but did not pursue the problem.
Vehicle when turning left such as at an intersection will continue to turn unless the steering wheel is manually returned to the straight ahead position. In other words if you are not paying attention the vehicle will continue to turn and would turn in a circle. This occurs sporadically. When taken to the dealer their repsonse is that Toyota is aware of the problem and that it usually occurs when turning to the right. They are working in the problem. Our feeling is that this is a safety issue and it seems to be getting worse in catching in the left turn mode. Toyota says there is no safety issue. They have been working on this problem for several months or so they say.
