I think that's normal. The cruise control adjust the gas NOT the brake. When going downhill, the car goes faster even without stepping on the gas pedal. It happens to all the cars I have/had.
Highlander, camry, sienna, Element....

Absolutely right! Cruise doesn't control speed going downhill. Gravity does.

I did not follow up the issue yet even if the problem was informed to the Toyota service in April 2006. The Toyota service who was working on the problem supposed to get a call back from Toyota Tech Support, according to the invoice dated 4/18/06, but I did not receive any calls from either of them. Mine mostly have the bubbling or peeling at the boundaries of the inside holes (close to the outer rim). I will be concerned more if it peels off at the rim near the tire since it will eventually develop slow leak once the corrosion spread into the mating surface (I had the corrosion problem with my Town & Country after years of usage at about 70k miles). I also think that the corrosion problem at 20k miles is not acceptable. The wheel should be covered by Toyota's basic warranty since it is not a normal wear item that they exclude. It supposed to be a life time part. If I have to keep this vehicle for long and if Toyota does not provide a solution on this problem then I may have to clean and repaint the area to stop the spreading.

On the contrary, some vehicles have speed reduction with cruise control down hill. My '95 Caravan will down shift with cruise control going down hill to prevent gravity acceleration. Roy

I agree. I have driven any number if vehicles with cruise control and all but one (older) down shifted or decelerated to keep the speed as set.
The upper range sienna (Limited)with adaptive cruise control will also apply the brakes in an emergency situation such as when the driver is nodding off and a vehicle slows ahead of them.

I've got an '05 XLE. I definitely noticed it downshifting while driving in the Poconos in PA. I even asked a cousin who just got a V8 Toyota Sequoia and he said his downshifted going downhill as well.
Unfortunately, I don't remember if I was driving with the cruise on. I do know that I was using the brakes, so I would guess that would disengage the cruise. Maybe it's a combination of braking downhill with the cruise intially set that starts the downshifting?
Don't know what to tell you.
#2172 of 2209 06 Sienna LE: a couple of low clunking sounds after fully stop
Oct 08, 2006 (10:46 pm)
I newly purchased a 2006 Sienna LE, mileage is only 70 mi now. I am very satisfied with its performance and quietness during drive. However I found out one small issue - very often I fully stop my car at the traffic light, I will then hear a few very low clunking sounds (very similar to brake's grinding noise)from the back. Since I don't turn on Air conditioner, fan, and radio, and the car is fully stopped, it should be noise free at that moment I don't understand why there is such funny noise. Please kindly advise.
#2173 of 2209 3rd row head rest problem
Oct 09, 2006 (7:21 am)
I notice all 3 head rests in 3rd row are hard to pull out.
Especially after unfolding from the floor. There is no way a normal person can pull the head rest in and out.
I am not sure if WD-40 will help?
just want to see if anyone has the same problem.

This is one of the many problems that the 2005 XLE Limited AWD I had for five weeks had when I made the Dealer eat the car or face a law suit. They denied that the head rests were difficult to move even when their own people could not move them without exerting extreme force. I believe this is a know safety problem to Toyota. The IIHS gave the post 2004 Sienna's a Poor rating (the lowest) in rear crash protection head rest performance. If you can't easily place the head rests at an appropriate height for the occupant it virtually guarantees an injury in the event of a rear crash of even the slowest speeds. I have been a lifetime fan of Toyota and am very dissapointed in their neglect. IIHS is showing the same results for the 2007. Does anyone know if Toyota plans on addressing the rear crash protection on these and other Toyota vehicles?
