STRUCTURE:BODY
I parked the car in the garage and my child left the passanger side sliding door open. Then, the door malfunctioned because it would not electronically close after being left open more than 80 minutes. I tried to manually close the door, but encountered resistance. Afterwards, I pushed the "power door main switch" and was able to close the door manually. Our safety was at risk because if a dangerous person or aniaml was approaching, there is no intuitive way to quickly close the door. The vehicle DID NOT provide any warning messages about the door malfunction.

UNKNOWN OR OTHER
The spare tire, which is normally secured under the minivan, fell off while driving at approximately 40 mph. My son, who was driving the vehicle, heard a sudden loud noise from the underside of the vehicle. He looked in his rearview mirror and saw something in the middle of the road. He pulled over to inspect the vehicle, and noticed that the spare tire was gone, which he was able to retrieve. I brought the vehicle to a local Toyota dealer, who indicated I needed a new spare tire carrier (at a cost of $329.07), since the original unit had failed due to rust. The spare tire had never been used or removed from its manufactured mounting position since original purchase of the vehicle in 2014. There were no warning signs at any time prior to the incident that the spare tire might come loose from its mounted position. The safety issues associated with this incident are obvious, e.g., another vehicle striking the spare tire or loosing control to avoid the spare tire; the tire rolling and striking a person, another vehicle, or damaging property, etc.

SERVICE BRAKES
The brake peddle is too small, it feels like my foot is going to come off of it or miss it. Some time's I lose a second or two trying to locate it with my foot, very frightening, and dangerous Every vehicle I have ever owned had a brake peddle twice that size. Yes it's a mini van, but the brake peddle does not need to be mini. This vehicle can carry 8 adults with lots of extra room, it should not even be classified a mini van. The brake peddle is less then 4 inches wide. Please look into this dangerous issue. Photos attached.

Vehicle traction control system will activate around a curve and break the vehicle while the traction control warning system activates. Breaking around a curve in a wet road situation can be very risky. Numerous other Toyota owners have filed similar complaints.

SEATS
The 3rd row seats in the Sienna do not stay stowed as there is no lock. This creates a very dangerous situation when braking. I just got this car a few days ago and already have issues. When I brake or go over bumps, the stowed 3rd row seat pops up a little. That's okay, until you brake. In one instance, I had to brake harder than usual during a traffic incident in front of me, and the 3rd row seats flew forward (up and out of the stowed position) and slammed into the 2nd row seats. It was loud and scary. My child was sitting in the 3rd row (split 3rd row so only one side was stowed) and the seat flying up and forward almost broke her leg as she was sitting with one leg out to the side. We even had items on top of the seat to keep the 3rd row from bouncing and popping up, but that is not a safe solution either. This is an issue reported for recent years on Toyota forums. I called Toyota to report it. I have read the owner's manual to make sure I am stowing the seats correctly. Any animals or children near a stowed 3rd row seat could be seriously injured.

FUEL/PROPULSION SYSTEM
While traveling at a high speed, van's power train jerked hard and rapidly slowed on its own, not allowing me to excelerate. Almost rear ended by following vehicle that managed to swerve around to avoid my rapid deceleration. Check engine light came on and was hard to start. Had to allow the van to sit a while before I was able to start. Van acted like it was in limp mode. This malfunction has occurred several times. Mechanic code shows P0087 fault code. Low fuel pressure. Toyota has recalled many of these vehicles in this year for this issue, but mine seems to not be one of them. Very dangerous.

SERVICE BRAKES
I had my car's brake lines replaced at McGee Toyota in Hanover MA on June 20, 2023. On July 19, 2023, my wife and I had just exited the interstate, and were stopping at a grocery store on our way home. I tried to brake upon entering the parking lot and the brake pedal sank to the floor. There was no resistance when I tried pumping the brakes. Fortunately, I was traveling at a slow speed and there were no moving cars in the lot, so I was able to safely stop the car without an accident. I had the car towed to McGee for repairs and the next day was told the catastrophic brake failure was due to a defective part. Since this would likely have had much more serious consequences such as serious injuries or worse if the failure occurred on the exit ramp or at the busy state highway intersection in front of the grocery store, I wanted to report it to be sure it doesn't happen to someone else.

STEERING, ELECTRICAL SYSTEM
Issues with VSC. The sensor alarm goes off when driving at more than 50 mph and slightly turning the steering wheel. The car brakes itself and this is DANGEROUS. It happens all the time, it has been more than 5-6 years and we are to the point of not using the car on the freeway to prevent a potential fatal accident. I found posts describing the same issue with this model of Toyota. Car should be recalled to get this fixed.

POWER TRAIN
My car was not shifting gears, and it would go into brief periods of erratic acceleration. I took it to the dealer service dept. The transmission went bad. It had metal pieces broken off inside it. The car is 3 years old and only has approximately 70,900 miles on it. It was dangerous to drive. It put me, my kids, and other drivers at risk due to the erratic shifting it would do while driving. The issues started slowly on 6/23/23. The check engine light was on by 6/24/23.
