Sliding door opened as usual, with a van full of 3 children, age 8 and under. Pouring down rain, the door decides to malfunction, and would not close electrically or manually. I had to drive home w/ the door open. The problem has since been ongoing and now we just don't use the door.

The power sliding door stopped working.. upon close notice, it looks like the cable is broken. I am surprised to see this issue on my 2011 model Sienna xle all wheel drive. It looks like there was a recall related to this issue in the previous generation as shown in this link. media.fixed-ops.com/toy_campaigns/csp-zts.pdf. it seems like the extended warranty covers models from 2007 to 2010... but my car is a 2011 year model purchased during 2010.

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. My husband had to tie the door shut in order to take the vehicle to the dealer where the expected repair part was $937. I thought buying Toyota was buying quality but, I guess they don't make them like they used to. I'm not sure if this is a design flaw that Toyota needs to evaluate before someone gets seriously injured or loss of life occurs but, it's fours years old and door complaints, after doing soon research are nothing new. Next vehicle.. if I still need the passenger space a minivan has to offer I think I'll look at Honda instead.

Sienna 4WD 6-cyl

  • 24,800 miles
I was backing out of my driveway and heard a clunk. The area was clear so I didn't hit anything. Lost power steering and power brakes. The information screen flashed messages to check brakes and contact dealer. I drove back into driveway with difficult steering and slow enough to not need brakes. The engine was running fine. I shut it off thinking something needed to reset. It would not start again. Hat it towed to dealer. They replaced a fuse ($445 + towing). My concern is that if this had happened while in traffic at a higher rate of speed, it would be difficult to steer or stop. The dealer stated they had never seen this before where the engine would continue to run and the fuse is usually blown if someone reverses polarity during a jump start. I have had the vehicle for over 1 year and have never jump started it.

I was parking the car and needed to move the vehicle backward in a parking lot with a slight slope. When I attempted to move the shift lever to reverse the lever locked up and the vehicle started to roll backward. I applied the brakes to no avail and the engine died. The steering was locked. The ignition switch also locked. The vehicle stopped. I called the Toyota dealer and the service manager said to apply the brakes vigorously, at the same time pump the accelerator and turn the ignition. I did and the functions all started working. No damage, no injuries. This occurred in fredericks burg, tx this appears to be the same incident in complaint # 10585286, dated 3-17-2014.

Within one week of purchase, the driver side, power assist sliding door failed to open completely. After initially opening six inches it would only move four inches in either direction by pulling the exterior handle. Only with multiple pulls/jerks could the door be fully opened or closed. This problem would manifest unpredictably, most often with the driver side power door, but once with the passenger side. Otherwise the doors functioned properly about eighty percent of the time. This failure appears to involve a safety feature which prevents the door from advancing when sufficient resistance is met. In all cases of failure no mechanism for resistance was found. My fear is that the safety feature may also fail when it needs to perform properly, to prevent an arm or leg from being crushed.

While driving down the road in the van with 7 elderly people it caught on fire and smoke came into the cabin via A/C vents. I pulled over and all 7 of us scrambled to get out of the van. Fire was pouring out from underneath and black smoke out of the hood. Within about 20 seconds after we got out, the van was fully engulfed in fire. The van was totally destroyed and only the metal frame was left. The fire investigator hired by my insurance company believes the fire started in the ECM. There were no warnings at all except the smoke in the cabin and from under the hood. We were extremely lucky to get out alive as we are all over 75 yrs old and not all of us in great health. The van is a total loss and my Toyota is aware of the event and a claim number assigned to us.

The powered fold up ramp and motor locked up completely blocking wheel chair exit and entry access in the Toyota Sienna 2011 braun ability rampvan. The alleged manual ramp operation function failed to work trapping the wheel chair occupant inside the vehicle. This dangerous design has been made since 2011 and continues to be made into 2013. Braun has released another in-flloor ramp option this year which is a much safer design that is impossible to block door access even if it malfunctions. Braunability needs to recall this design and make a true manual release that disconnects from the motor incase of failure or lockup. My son is severely disabled and has alot of medical equipment. The jump seat bolted to the other side of the floor blocked entry and exit clearance for a wheel chair on the other side as a possible alternative emergency exit. We had to literally pull him out of his wheel chair and disconnect his equipment - all very difficult in the tight space and very dangerous especially in the case of an emergency. This is an extremely dangerous defect and should be address immediately. The van was towed and in the shop for 3+ weeks to fix this issue and replace the equipment.
