I was driving my 2016 Sienna 30 mph, when suddenly, the rear driver's side window exploded. The police came and inspected the incident, the surroundings and the vehicle, and determined that there was no object or strike to cause the explosion. There were no warnings or lamps. There was no pressure change such as a window or door opening to cause the explosion. Should the glass have imploded, we would be having a very different conversation, as my two children were in the vehicle with me. The safety of my two children was at risk due to the glass exploding. We called our local Toyota dealer, and they claim to have no information on dealer notifications, recalls, or even heard of such a thing, perhaps to avoid having to pay for the repair. I have attached a photo of the damaged window.

There is something mechanically wrong with the design of the suspension that is causing tires to wear completely in 15K-20K miles. This is a known issue, and nothing is being done about it. Https://www.cargurus.com/cars/discussion-T34192_ds548164

The Sienna emissions control design has an inherent problem with its mechanism which cannot be diagnosed properly at the service shop. My 2008 was serviced about five times for the same problem, during which the carbon canister was replaced at all occasions to fix the problem. On the dashboard the check engine light + trac off + vsc lights come on. It indicates something serious is wrong with the vehicle. Please read this web link for complete details. Why is this problem not a recall as Toyota has no intention to fix it "?" :( Toyota-Sienna-canister-defect.blogspot.com/2017/10/the-Toyota-Sienna-2008-2016-carbon.html truly, [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

The driver side window seal comes out when you roll the window down. The window then will auto go back down because it senses something in it's path (which is the actual seal). I have to slowly work the seal back in the frame. The dealership milton martin Toyota implied it was because I did not keep my window clean enough. They have greased it, didn't work. Then they put a new seal in, that is coming out now. And now they are putting another new seal in. This happened at about 34K miles.

The windows on all 4 doors of this vehicles are constantly having dirt/debris getting inside the door. You can see this on the windows, and the front ones are the worst. It's a constant source of issue with scratching sounds from the windows going up and down. The other issue that has been ongoing for 4-5 months is the driver's side window seal - it becomes detached from window frame and eventually goes back into place once window presses into the door. I have had the seal put back in by dealer, however, the fix didn't last 2 months. Please advise.

2016 Toyota Sienna dash head display, radio go out. When this happens headlamps go dim to point where you can barley see and have to stop the vehicle. Took this in to local dealership several times they stated that until it was happening in their presence there was nothing they could do. We were able to video record the issue and showed dealership. They replaced the radio head but issue still occurs. Also have problem with recall on sliding door. Dealer stated that Toyota was still looking for a fix. I have had door open and close on my young children without notice. Have the power turned off to doors now but bought this model for the power doors due to being a disable vet this feature helps me out a lot.

Passing a construction zone on highway (at speed about 40mph), several small gravels hit the windshield and made a few chips. Something like this happend to my previous car too, but never made any damage at all. So I suspect the windshield on 2016 Sienna is not strong enough and worry about its safety.

Toyota Sienna faulty power sliding doors. The vehicle was parked. When we tried to open the door, the cable snapped. Then we won't be able to close it. We had to cut the remaining cable behind the sliding wheel to manually close the door.

Received notice in the power sliding door malfunctioning. Toyota has failed to provide a solution and refuses to provide a loaner car. Toyota indicated that one should not drive in the back seat because the door could potentially open. With something this serious, how can they not provide a loaner car to their customers until a resolution is found?! this is highly unacceptable and horrible customer service from Toyota.

Nothing has happened yet with my vehicle but Toyota just sent a letter with a recall on the automatic doors on their vans from 2011-2016. Children ride in the back seat of vans and they are putting them in danger. They don't have a fix for this besides to turn off automatic doors which is a main feature of the van included in the cost of the vehicle. It is unacceptable that they have no fix for these and aren't offering partial refunds to owners that have paid for those features. Toyota needs closer regulations on their vehicles because they have had so many recall issues it is ridiculous. Not to mention putting children in danger with this new door issue. I hope that they are fined and regulated more in the future so that they don't continue to put our children and families in danger.

The vans that have been converted to a handicap/mobility van are unsafe for others to drive once the driver seat has been removed. I have contacted the local company responsible for the conversion, and they told me to sit on a dinning room chair or a bucket. That is definitely not a safe option when a non handicap person needs to move or drive the van. I believe there needs to be a seat made that can clip into the wheel chair clamps that the handicap driver uses.
