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.

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 ??? :( http://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). *tr

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.

Power sliding door cable snapped. It happened to both door (right and left) about 6 months apart. Had the car for about 2 years not not even excessive use. The first time was at a dealership for vehicle service and they fix it for free since it happened there even though they said warranty does not cover. The second time was over this weekend and when I search online, many people experience the same problem. Poor quality cable (linkage) for the powered sliding door.

Our van has recently been having issues with the sliding doors. It has occurred while driving and the warning light as well as the warning for a door open, and the door lights have came on.

Blind spot monitor only activates when passing car reaches rear fender which is insufficient warning -- unsafe at all speeds. If you were to depend on it when changing lanes it could cause a serious accident. My 2013 Lexus also has bsm which operates perfectly with good and sufficient warning for lane change.

This new Toyota sienna 2016 was delivered with a defective front windshield with distortion at the center bottom. It causes the road markings to become wavy and distorted, and is dangerously distracting especially at night or in low light situations. The dealer was immediately notified, and checked other siennas on the lot, all of which have the same defect. The dealer directed us to Toyota, and Toyota failed to respond and did not correct the issue.since it is apparently a vehicle wide defect, it seems a recall would be required to address the issue.

Our 2016 Toyota sienna spontaneously caught fire while parked in our driveway after returning from a short drive. After pulling into our driveway and shutting off the ignition, my wife smelled smoke as she was exiting the parked vehicle. This smoke intensified and quickly accelerated becoming an engine compartment fire. She called for me & then called 911; but in the brief moments it took me to grab a fire extinguisher, the fire further intensified with sizable flames erupting out from around the hood, front grill & underneath the vehicle. I used up 2 fire extinguishers without any significant effect. I did not have any protective safety gear so after hearing several small explosions coming from under the hood & fearing more exposure to noxious fumes, I decided to abandon my attempts to
