Because I live on a dirt road; I am assuming that built up on the window rollers, have damaged my windows. My windows are scratched, to the point where it affects visibility. I thought the scratches were on the window tint (interior); but it turns out, it is on the exterior (the glass). I went to a window repair shop, hoping they could resurface the glass. They said there is no repair and that I would have to replace them. Replacing 3 to four windows would cost over a thousand dollars (tint extra). I am very disappointed because apart from the hideous look, my families safety is at risk. I chose not to replace the windows, because the rollers will just begin the process all over again. If you live on a dirt road, I recommend you either wash your car, very regularly or don't roll down your windows at all. The latter is very difficult for us to do. I live in southern California, and it gets very hot; inside a parked vehicle. When I put my children in the car; I roll down the windows immediately, and start the a.C; to bring the temperature down. I hope Toyota becomes aware of this problem and installs better rollers, or offers repairs. Thank you.

The rear window on the hatchback door blew out. The vehicle was parked in the garage overnight - the next morning it was shattered. I contacted the dealer to find out if this was a common problem - I was told no. However upon performing a google search I found hundreds of instances of people complaining of the same issue. It was also interesting to note that the rear windows were/are on national backorder from Toyota. The window installed in my van was apparently a "take off" from another vehicle. I am highly concerned that this issue will occur again, possibly next time while driving or with my children in the vehicle.

The windshield defrost system is inadequate. With the "auto" system on, and/or the fan on maximum, and/or the windshield defrost press on, the upper 1/3 of the windshield remains frosted over. This seriously affects visibility and safety. The fan seems to be blowing hard, but air flow from the defrost vents seems weak. The problem is most apparent at or near sub-zero outside temperatures.

The contact owns a 2013 Toyota Sienna. The contact stated that the windshield could not be defrosted. The contact engaged the defroster on full blast but could not clear the windshield. The contact took the vehicle to the dealer and was told that there was not a remedy available to correct the failure. The contact spoke with the manufacturer and was told there had been similar complaints, but there was no remedy available. The VIN was not available. The failure mileage was 10 and the current mileage was 1,000.
