FUEL/PROPULSION SYSTEM, POWER TRAIN, VEHICLE SPEED CONTROL
Was driving on highway at 60-65 mph. The car continued to accelerate. Pressed on brake and wasn't slowing the vehicle. The driver was weaving in and out of cars as the van started to creek up to 92 mph. The driver and passengers thought they were going to crash and possible die. The driver tried the brake multiple times and nothing. The driver said the accelerator pedal wasn't pressed all the way down to the floor. It was half way and driver had to go down and pull up on the pedal while driving. The van then started to slow and driver was able to pull over to have the van evaluated . The throttle body was reached and cleaned of carbon because it said that this may have been part of the issue. Never has this van taken off like this. The throttle body cable wasnt loose or disconnected either. So far we havent been able to recreate but 3 people could have been killed.

VISIBILITY/WIPER
Driver side outside rear view mirror shakes and makes driver nauseous. Mirror was replaced in December and replacement mirror shakes as well. Right side (passenger) doesn't shake. Vehicle now has 6500 miles on it. Original equipment windshield has a wavy appearance for the right 1/3 of it (in front of the front passenger seat). Both issues have been brought up with Mitchell Toyota in San Angelo, TX. The dealer will not replace the driver side mirror again, saying "some movement is allowable", even though the passenger mirror doesn't do it at all. They also said that the windshield waviness is "normal". These issues are in addition to other issues I've had with this Sienna, from moldly HVAC smell that caused my eyes to sting and tear up last week.

VISIBILITY:REARVIEW MIRRORS/DEVICES:EXTERIOR
Wobbling vibration on exterior mirror, driver side. It looks like incoming vehicles shake sideways. This happens on any bumpy road and it is easier to observe at highway speeds. Purchased on [XXX] Vehicle is available for inspection. The distorted image resulting from mirror wobbling affects driver's awareness of surroundings, visibility gets worse at nights/rain due to blurred lights. This can lead to an accident. My intuition when I first noticed was going to be a cold break but I realized that it was the mirror wobbling causing it. The car coming behind was far enough and I was able to react. Summary of actions and requests to Toyota: Two dealerships in central Texas have confirmed the issue but case was dismissed. Details below. 1. Dealership 1: Issue acknowledged by shop foreman , mirror changed but this did not fix the issue. Opened case with Toyota Brans Engagement and requested to work with a different dealership. This is the dealership where the car was purchased. Report wrongly stating rattled noise they weren't willing to correct it and pushed me to sign. 2. Dealership 2: Issue acknowledged again. Since mirror change did not fix issue shop foreman opened Dealer Product Request. 3. Current status: On 1/3/25 Toyota Brand Engagement advocate called to say that even though the shop foreman at the 1st and 2nd dealerships acknowledged the problem, the resolution was that it was a "normal" condition for the car. Case Reference #[XXX]. No warnings related to the problem. First occurrence: Day one, driving back from the dealership. Conditions were probably not met during test drive (you need to pay attention, more on that in the body of the post). Confirmation on day 2 on another drive, all with less 2 digit mileage, perhaps low 100s. Posting my case online has gotten 4 people reporting the same issue with cars since 2021 in multiple trims. Similar issue on RAV4 reported on [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

UNKNOWN OR OTHER
The sliding doors will shut off after 60+ minutes of being left open. In order to close them afterwards, you must fight with the power closing mechanism which makes it incredibly slow to close. This is dangerous if someone is threatening you and you need to get in your car and close the door. Or if a swarm of bees is coming at you. It takes about 30 seconds to close the door when this happens. Toyota claims this is to save power but this makes no sense as an excuse as the rear. Liftgate can stay open indefinitely without problem.

Car lunges forward 10ft or so intermittently when braking is applied. This is very dangerous given situations. Toyota dealer is given new car models under 36k miles a free fix, but they would charge high mileage cars a lot of money. I wish NHTSA demand Toyota provide free fix for this issue.

ENGINE
Hello, leader. I bought my car (Sena Platinum Edition) for three months. Due to a mistake in the appearance, I need to replace the engine now. My new car will definitely depreciate if the engine is replaced, so I hope Toyota headquarters can refund me in full. I need to buy a new Sena! My house is full of Toyota cars, no matter what the result of Toyota Company's handling? I will still choose to buy a Toyota! Thank you!

POWER TRAIN
While trying to accelerate on an onramp to the highway, the transmission failed to enter into higher gear, and the check engine light came on. The 2017 Sienna currently sits at 112,951 miles. Leading up to this, we had noticed the van jolting when being put into drive or reverse, and acceleration was often sluggish, with a whirring sound. Inspection by the local Toyota dealership found that the entire transmission needed to be replaced. The serial number of the transmission starts with UA02, which wasn't part of any of the existing 2017 Sienna service bulletins.
