Both power sliding doors have become inoperable. It is a safety issue because my children cannot open the doors from the inside of the vehicle. Toyota will not stand behind their product.

Master head unit, including navigation, rear camera, bluetooth, and stereo, stopped working. It makes a clicking noise but the screen is dead and does not respond at all. Appears to be from a design defect that causes overheating of the unit over time. Multiple reports of similar failures are all over the internet. This is a significant safety issue as the rear camera, bluetooth, and navigation are all important items for extra safety in operating the vehicle. I think most people would expect that a non-mechanical part (like the radio/head unit) would last longer than 6 years, especially when it cost several thousand dollars.

The vehicle has a rheostat in the circuit that controls power to the dashboard light, activated when you turn the nighttime driving lights. The rheostat has failed, you can't see the dashboard at night, already cost me one speeding ticket. I spoke with a number of Toyota service centers, none could give me an idea of the issue or how much it would cost to repair. All of the dealerships were rude, complete disregard for occupant safety. Toyota wants about $1,000 to replace the entire dashboard. The rheostat probably costs only about 30 cents. The design is over-engineered and unsafe...

Passenger door the electronics just stopped working. I've been told I can use this manual right now but eventually will seize up by the dealership. Very costly part. Researching on line there are many owners of this van with the same issue. No voluntary recall on this part. I find this a safety hazard as you do not know when the door may cease to open. In the event of an accident on opposite side of van and door will not open and the passenger side no longer works, people in the back of the van will be trapped. Not sure why Toyota has not had a recall on this part.

We were stopped when we tried to open the passenger sliding electrical door. It opened about 8 inches and then it would not open or close. No matter how hard we tried we could not get the door to open or close. Even the manual override would not work. We were out of town and my husband had to sit by the door as we drove home 40 miles. The Toyota service was not open and we had no way to get our family 0F 7 home or anywhere. It was a very dangerous situation.

I recently had my airbag light flashing on my dash and the dealership said both rh and LH air bag wiring harnesses with sensors will need to be replaced. The cost to fix $5335. I recently had my power sliding door go out. The door opened but would not close. The cost to fix $1800.

Automatic power sliding door on the passenger side recently stopped working correctly. The door motor tries to open the door but often stops after only moving an inch or so. Once you get it to open (either manually or with the power open option when it randomly works) door will not close when buttons are pushed. The door again will move 2 inches maximum and then stop. If you are able to manually close the door (which is very hard to do) it does not always latch completely closed. This is a major safety issue. If I can not open the door at school to drop off my child, what is going to happen in an emergency when I need to get my child out? I have found hundreds of similar complaints on multiple web forums, Toyota needs to replace the defective part that they quoted me almost $900 to fix.

Our Toyota Sienna 2006 airbag light had been going on and off on the instrument panel. Took it to the Toyota dealership, they insist they have never heard of this problem. There are multiple complaints on the internet for this model and year. Not to mention other models being recalled for the same problem.. they are not diagnosing the cause but trying to replace the entire system.(wiring harness, sensors and airbags) I believe an investigation as to the faulty component or components are in order. Are the replacement parts they are wanting to use the same as they faulty ones. Are any of they airbag components in the Sienna the same as the Toyota highlander. (sensors chips, wiring harness). The dealership says they are using the same components that were originally were installed. Have read multiple forum complaints of people on there second or third total replacement of the entire airbag system. The dealership said it could take one to two months to get the parts because of national shortage. Again a shortage, are too many Siennas have the same problem, or are the components that are faulty similar to the highlander and are being used in that recall.

My eight year old daughter got her four fingers on the right hand crushed by the sliding passenger automatic door when it was closing. The door did not open like it should. She does not feel the tip of her fingers. Help!

The air bag warning light came on. I took the vehicle into the dealership to have it looked at. The result was that the wiring harness for the seat sensor on the passenger side has corroded creating an open circuit. They gave me an estimate to replace the wiring harness and air bag (which has been apparently damaged due to the corroded harness) to a total of $3,000. Wiring harnesses do not corrode in 5 years unless the part was defective at installation. Since the SRS system is a major part of the vehicle's safety systems and the system was designed to operate as a whole, repair is mandatory in order to insure occupant safety. Searching the internet there are literally 100S of instances of the exact same issue with the 2006 and 2007 model years. The fact that this issue is a fault in the vehicles safety system and the high incident of this failure occurring I believe justifies a recall for repair of the system by the manufacturer.

I bought a 2006 Toyota Sienna le AWD for my special needs daughter.the sliding door snapped a cable and wouldn't open.,so I had to crawl in from other side to get her out, that was not a easy task B/C she is immobile and could not help me with getting her out of special carseat and brace..I think this should be Toyota's job to replace or at least help with replacing, if not I will never purchase or recommend this van to anyone..I had her special seat on that side just for that reason and I will file a claim with this..

Power sliding door stopped working, passenger side. I went out to load the kids in the van, and the power door opened about half way, then shut by itself. I then tried to open the door again, but it would only open a tiny bit and would not shut. I did not use the door any further until I took it back to the dealer to have it looked at. The final verdict, 1400 dollars to fix the door. I bought the van 2 weeks prior to this happening, and it only had 61,000 miles on it. The dealership refused to help out in any way, except that they did cut the cable and now we can use it as a manual door. 5 year old van with 61,000 miles, and the automatic door failed. I wish I would have done a little more research, as this seems to be a very common problem that no one at Toyota wants to address.

Auto sliding door will not close tightly- looks closed then when you put it in drive or reverse, the door beeps and opens. Takes multiple times of pushing door button to get it to shut tight. Sometimes you have to get out and try and push it to lock. It is very difficult and now I don't use it because I'm afraid it won't close and a passenger would be in danger.

The back passenger side door of my Toyota Sienna does not work properly. When the button is pushed to close or open the door, nothing happens. It will open and close when the handle is lifted and the door is guided a little on the track. I have looked online and it seems to be a very common issue with Toyota Siennas. This disappoints me as it is a very expensive repair! I think a recall is in order.
