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
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
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? No. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear?

STRUCTURE:BODY
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.

UNKNOWN OR OTHER
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.

ELECTRICAL SYSTEM, ENGINE, FUEL/PROPULSION SYSTEM
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 EXTINGUISH THE FIRE. THE FIRE DEPT. ARRIVED WITHIN A FEW MINUTES AND WERE ABLE TO PUT THE FIRE OUT; HOWEVER, THE FIRE PROGRESSED THROUGH THE INITIAL ATTACK AND ENTERED THE PASSENGER COMPARTMENT CAUSING SEVERE DAMAGE TO THE ENTIRE VEHICLE (SEE ATTACHED PHOTOS). THE SIENNA IS COMPLETELY DESTROYED. FORTUNATELY, THERE WERE NO INJURIES. I HAVE BEEN MADE AWARE OF MULTIPLE INCIDENTS OF ENGINE FIRES IN TOYOTA SIENNAS IN THIS & OTHER CLOSELY RELATED MODEL YEARS (2014-2017). SEE: NHTSA ID NUMBER: 11010601. I CAN ALSO SUPPLY YOU WITH SOME ADDITIONAL MEDIA ACCOUNTS OF OTHER TOYOTA SIENNA ENGINE FIRE REPORTS. OUR SIENNA WAS ROUTINELY MAINTAINED AS PER MANUFACTURER'S RECOMMENDATIONS & WAS LAST SERVICED ON 9/13/2019 (SEE ATTACHED SERVICE RECEIPT). THE VEHICLE HAD APPROX. 35K MILES ON IT & EXHIBITED NO PRIOR SIGNS OF TROUBLE, CHANGE IN PERFORMANCE OR WARNING INDICATOR LIGHTS. WE DID HAVE AN UNRESOLVED PROBLEM WITH AUTOMATIC SIDE DOORS NOT OPERATING PROPERLY AFTER A RECALL REPAIR; HOWEVER, THE LOCAL TOYOTA DEALER SERVICE DEPT. COULD NOT IDENTIFY A PROBLEM AFTER MULTIPLE SERVICE COMPLAINTS.
