The latch on the back door melts when the weather is hot, leaving a black, tarry mess in my hands. Now that the weather is cold, the latch on the back door is frozen solid, making it extremely difficult to open the back door at all. This could be dangerous if I need to open it quickly. The van is, of course stationary when I try to open the door. The dashboard also melts in the heat.

The contact owns a 2010 Toyota Sienna. The contact was driving approximately 5-10 mph when he attempted to switch off the interior lights and instead, haphazardly engaged the automatic door switch, causing the side sliding doors to open. The vehicle was taken to the dealer where the contact was advised that the design of the vehicle could not be compromised. The manufacturer was contacted and offered no assistance. The failure and current mileages were approximately 50,000. The VIN was unavailable.

Sliding door driver's side on 9 month old 2010 Toyota Sienna has failed twice in past three months. The sliding door closes and is unable to re-open. Previous to the two failures, door has only been locked and closed using remote control, handle from outside, or locked automatically upon accelerating. Because an infant occupies the seat for that door 100% of the time, door is never opened or locked from the inside and is never touched by passengers from the inside. Dealership indicates that the inside lock lever is being manually forced past the lock position when closing the door; however, the inside lock lever has never been used at all by any of the owners. Dealer reassembled the lock controller to correct the issue the second time.

My 17 month old's head got jammed between the right rear wheel and the right rear door panel while the electric door slid open. Even though my wife pulled on the door handle the door kept sliding open. My baby's head was crushed between the tire and door panel. This is a very unsafe design as my wife tried to stop the door from sliding back and the door kept moving. I need someone to call me to further discuss this matter. My car is a 2011 model.

2010 Toyota Sienna rear liftgate automatically closes on occasion without pushing the key fob or the interior button. It has occurred 5 times in the last 2 weeks. No one has been hit by the door yet because we are aware of it happening. I will be contacting the dealer tomorrow. No other action has been taken.

We have a 2010 Toyota Sienna xle. The problem is with the automatic doors and key fob and back hatch door. The key will unlock and immediately relock all the doors. If you touch the buttons to activate sliding doors they work off and on. The big problem though is the back door - the trunk. It opens and then as you are going into the trunk you don't know it is closing on you. This has now happened at least 12 times. I am concerned if my child is in trunk getting bags. It seems some "eye" must see and the door starts rising again. But I have been hit in the back and head a few times. My concern is what if the sensor does not activate and you are stuck in the door/bumper area? I am taking car to dealership but they claim to have never heard of a problem like this.
