| Description of the problem | I suspect the cruise control of my 2004 minivan toyota sienna ce has similar issue found in recent prius reports. 1. When cruise control is used on uphill road conditions 2. The speed can be accelerated to over 5 miles/hr more than the cruise control setting. For example, when i set the speed to 70 miles/hr, at a little longer uphill road, the speed will drop first (like 67miles/hr) and then accelerate in order to get back to 70miles/hr speed target. But the cruise control system continue accelerating after passing 70 miles/hr and could be as high as 75miles/hr. 3. Nothing had been done, just be cautious by myself. After reading similar complaints on prius of toyota, i feel this may be the same issue. *tw |
