No accident t door on the rear passenger side will not open I have tried everything and it just will not budge. This is a safety hazard because in the case of an accident or emergency, the door cannot be opened. It will not move manually or automatically.
I have complained about both rear sliding doors acting erratically for almost 3 years. These doors were under a recall, as they sometimes were overloaded and would cause the fuse to blow and the door(s) would/could swing open while moving. It happened to me NUMEROUS times. Once it was so bad, that I couldn't bring my son yo school because the door wouldn't stay shut. They beep upon auto open and you have to fight the door open or shut no matter if you switch off the "auto door" button or not. It has been to 3 different dealers in less than 3 years. The first dealer only replaced one junction box, and wiring harness on the passenger door because that it the only door that acted up while they were in possession of sienna. The door less than a 1000 miles later started to have issues - opening, closing, staying closed. …
Vehicle: 2011 Toyota Sienna XLE VIN: [redacted] Mileage: ~204,800 Incident Date: [redacted] Recent Service: Oil change, tire rotation, brake inspection, and multipoint inspection performed on November 10, 2025 at Fitzgerald Toyota Gaithersburg (Maryland). Description of the Defect: On [redacted] while driving with my child in the vehicle, my 2011 Toyota Sienna experienced a sudden and dangerous failure. A strong burning smell entered the cabin, the ABS warning light illuminated, and then wheels locked up while the vehicle was in motion. At the same time, the steering wheel locked, making the vehicle impossible to steer. The engine immediately lost power and shut down in the middle of the roadway. The vehicle would not restart and had to be towed. …
While parked in my driveway, having been driven two hours before, my van caught on fire in the engine compartment. It burned for an unknown amount of time before we were alerted. The electrical system was disabled by the fire causing the two back sliding doors to become inoperable. The van can seat 6 people in the rear passenger compartment and they would be unable to exit the van except by going through the front doors. Even now that it is after the fire, we are still unable to open them, from inside, outside, or with any of the buttons.
My van cut on fire last saturdar, September 1st 2019. For no apparently reason. I drove about 5 miles from my house to the grocery store, when I notice the smoke, I first though was the car in front of me. But was smoke coming from my hood. I was just about to stop at a stop sigh and I look the temperature gate and it was fine, turn of the car and people from the parking lot was already yelling for me to get out of the car. More than 2/3 of the van was totally destroyed in the fire.
Sliding power doors work intermittently and have needed to be forced open or closed on occasion. However I attempted to use the handle to activate the power door to open the door in order to place my son in his car seat, the door began to open, and then stopped after only opening an inch. The door ajar alarm began sounding. I pulled the door open packed my little one up in his car seat and went to shut the door. The door would not latch to stay closed and the door would move freely without the use of the door handle. The vehicle is now unsafe to transport anyone in as door can not be closed. At least this happened at home parked in the driveway. But if these doors are failing under normal circumstances I no longer feel I have a safe vehicle to transport my family in. Who knows what would happen under more stressful conditions. …
Recently started having this issue while driving on the highway. When changing lanes my door open indicator light as well as the exclamation inside the triangle will illuminate on my dash, a beeping sound starts chiming and all the interior lights come on. This happens about 15 times in a 20 minute period. Its very aggravating and distracting. It has gotten worse and does it on side streets and lower speeds as well now. I have done some trouble shooting of my own and realize that it only happens when I have a window cracked or down. If the windows are up it will also happen with sharp turns ending with abrupt braking. I have been pulled over 3 times in a 4 month period because of the lights going on and off. Police seem to think I'm sending some type of code for them to help me! It is ridiculous. …
