Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

On August 27, 2016 I was driving our 2012 Toyota Sienna on an interstate highway. Traffic was terrible and I rear-ended another vehicle in stop-and-go traffic. The impact was minor, but the engine caught fire and burnt the car to the frame. My wife and I were able to exit the car before it burned. When I exited the car, I took my keys with me. However, I was not able to open any of the doors and everything I had in the back of the van burned. Thankfully, our children were not in the car. If they had been, I would have needed to break windows to attempt to remove them from the car.

The sensor in the power sliding door of my 2012 Toyota Sienna, would not stop beeping even though the door was closed. The latch was rusting away, and Toyota wanted $1,400 to replace it. The driver's door latch is made of stainless steel, so why is the sliding door latch rusting" and why can't we disable the sensor"

It rained and froze, snowed and thawed, and the latch on the sliding door of my 2012 Toyota Sienna broke. The door would slide open and closed while I was driving it and would not stay closed. Fortunately none of my children were in the back seat when this happened.

I have brought the Sienna into Toyota on 3 separate occasions, as there was clunking when the lift gate closed. I was told there was nothing wrong with it each time, but the liftgate was and is clearly not aligned. Water is now coming through the top of the lift gate. I did back up into a tree, and had damage to the back quarter panel and it was repaired by a body shop. Toyota is stating that this caused the liftgate to be misaligned and that is causing the water to come through the liftgate. My complaint is I believe that dealership is avoiding realigning the lift gate. I originally brought this in under the manufacturer warranty and I have an extended warranty. There was no vehicle damage to the van upon initial visit. At this point, if the liftgate is not realigned and fixed properly and water continues to come in, it will eventually destroy the mechanism that is used for the auto open and close. In addition, I am also concerned about the overall safety of the vehicle in the event of an accident, if what Toyota states is true (the liftgate can be misaligned by quarter panel damage).

Toyota is stating that this caused the liftgate to be misaligned and that is causing the water to come through the liftgate. However, it was not until I ran the minivan through a touch free carwash and water was applied under pressure that I noticed the water coming in. My complaint is I believe that if the liftgate could be misaligned by quarter panel damage, what would happen under extreme stress of a car accident. I do believe the dealership is avoiding realigning the lift gate, but I am also concerned about the overall safety of the vehicle in the event of an accident. Also, the original tires that came on the vehicle wore very early. I replaced all 4 tires at Toyota because we were taking the vehicle on a family trip. I was looking through the owners manual and noticed that the original tires were to have a 6 year warranty.

I want to correct that on our 2012 Sienna it is the back sliding door that it is the "hinge" that opens and shuts the door, locks it, attaches it to the van that is starting to rust. Toyota reply is till it falls off, or starts to "be more rusted, but not in our lifetime" it is cosmetic, yet it is dangerous and will affect the resale value and it is near the wires that open and shut it, which I have read problems about. Toyota should take responsibility for the hinges rusting and replace them before someone does get hurt, you just don't wait for the accident to happen or till someone gets hurt.

Today while cleaning the van, I noticed the lever and/or latch that holds the back sliding doors and moves them open and shut, keeps the back sliding doors on, is starting to rust where the door is connected near the cables that open and shut the door.

The person sit behind the driver, push the automatic van door close button to close the door then reached over for the seat belt. The person accidentally reach the hand between the sliding door and door frame right next to the seat belt anchor close to the door. The door closed on the open finger and tried to close even tighter. The door mechanism did not reverse and open the door back up, but continues to try to close the door completely. After some hard pull on the door handle, the door finally reopened. The person finger was bruised and the wedding rings shape has been damaged. The ring is no longer round nor straight, it has been torqued by the force of the door mechanism.

Driver's side rear sliding door will not latch shut when closing door either manually of electrically. When closing front latches engage of sliding door but subsequent rear latching does not engage upon end of closing cycle. One can hear rear of sliding door locking mechanism actuator whine when attempting final close cycle. After the van's failure to cycle the door shut at rear, then also at rear a diagnostic sounds a long beep warning sound afterwards. Removing negative to see if this would reset the door in some way only served to cancel all electronic commands to the door to open or close useless from any button (fob, overhead control console button, manual door handle opening or open/close buttons). Passenger (right) sliding door unaffected.

Brand new Toyota Sienna. The moonroof/sunroof keeps leaking. Been to the dealer multiple times and when we come back the adviser always tells us the van won't leak anymore only to find out the next time it rains, the car leaks again. We don't know exactly when this started happening( we guessed it leaked a long time ago due to the rusted parts around the glass) since no one really sits in the back. The dealer already replaced the glass and the rubber seals around it.

The contact owns a 2012 Toyota Sienna. The contact stated that a child passenger was injured from the automatic rear sliding door. The sliding door independently closed on the child's arm.. the vehicle was taken to a dealer for diagnosis however, because an injury occurred the contact was informed that the manufacturer would contact her about the failure. The vehicle was not repaired. The failure and current mileage was 23,535.

Driver and passenger side power sliding door occasionally (I.e. not all the time) makes an abnormal pop noise when initially opening with the outside handle or with the inside handle on the sliding door. This does not happen the door is opened with other method (e.g. remote, over-head mount control, button on B-pillar). It seems as if the door doesn't unlatch before the motor start pulling the door. The symptom is very similar to this tsb for certain 2011 Sienna: T-sb-0044-11.
