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. Right before this occurs you can hear a click sound from the sliding door behind the driver's side as well as when you close the door, you can hear a strange sound when it closes, unlike the passenger side sliding door.

POWER TRAIN — Filed 12/12/2023

After 80,000 miles have a loud whirling sound coming from rear, after inspection and online investigation found many many others with same issue, the dust cover and or o-ring doesn’t properly protect the rear bearing in the coupler. So while the fix is to remove the rear differential coupler, and replace the bearing with an improved version, seems Toyota has stopped supporting this, and no longer offers the improved bearing as a replacement part, but only supports replacing the entire rear differential coupling at $2000 for the part plus labor. While many have replaced the bearing without issues despite toyota not allowing it as a fix. So first it should be a recall as this is an obvious defect effecting thousands, but then to gouge owners for thousands when the fix doesn’t require a complete replacement of the rear differential coupling assembly.

AIR BAGS — Filed 06/15/2023

A deer was struck on the driver to middle of the front of the van while traveling 75 mph on the highway. Caused significant enough damage that van was inoperable. What was concerning was the airbags did not deploy despite the significant force and high speed associated with this accident.

Also, as the incident was occurring, my drivers seatbelt became very, very tight. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others?

The rear sliding power door on the passenger side closed on my six year old child. He was trapped in the door and could not move until I opened the door. He has pain and visible injuries on his back from the door. This happened on 2.10.23. There have not been any incidents with the van leading up to this incident. This happened when the van was parked in the garage and the engine was off. We have not tried to replicate the incident because it caused an injury. The vehicle is available for inspection.

AIR CONDITIONER WORKS WHEN IT WANTS TO. NOT SURE WHAT SEEMS TO BE THE ISSUE.

UNKNOWN OR OTHER — Filed 11/07/2021

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.
