When pulling out of a parking lot, the accelerator disables leaving the car unable to move in the middle of the rode for a few seconds. The happens intermittently and usually when there is traffic going both ways in the area. This has happened several times but has not been replicated with a dealership employee during test drive. After the accelerator disables, it will enable after a few seconds. It has left me sitting in the road with cars honking at me. Van is currently in the shop. Brake pedal was not deployed at the same time of acceleration.

The wiring harness connector for both lights has had water accumulate in the connector which causes the rear tail lights to fail. Both of my tail lights have failed, and the cause was corrosion inside the wiring harness connector. I had to replace the wiring harness and connectors on both sides, driver, and passenger And I had to pay out-of-pocket. The dealer said that this problem is common on 22 sienna's and I have seen other 22 sienna's with out their driver and passenger rear running lights burnt out.

While driving at about 40mph on a city street I complete lost steering, brakes and vehicle control. I suddenly started severely swerving/ spinning. I suddenly had no control over the vehicle. The vehicle threw a bunch of codes at once including: anti-lock brakes malfunction, pre-collision system malfunction, secondary collision brake system malfunction, braking power low, parking brake malfunction. I tried to turn off and restart the car and it did not reset any codes. I have brand new tires on the vehicle and just had an oil change and check up two weeks ago. There was no reason for this to happen other than a complete and sudden safety failure of apparently multiple systems. Vehicle is currently being inspected by local Toyota dealer.

Ever since a tire was changed on the vehicle, it has had a recurring error message that states there is a malfunction in the tire pressure monitor system. As such, I rarely know the status of my tire pressure as the system has the malfunction at least 50% of the time. The car has been in service 2x for this issue and they have had it for close to 30 days and driven it all over saying they needed to drive it to make the error go away. They have replaced the sensors on the tire, nothing has worked and the problem still occurs daily.

Passenger air bag malfunction notification randomly going off (with and without items on the front passenger seat). I was told the dealership can’t diagnose it unless the alert is going off at the time the vehicle is dropped off.

Note: I have filed a complaint with the Florida Attorney General's Office Health Hazard. Mold Issue. Flooding Issue. Failing weather striping. We had a weather strip on the rear door get misplaced or is failing to stay on our 2022 Sienna. Toyota won't cover it. And we will have to make a claim per their recommendation, unsure. Third seat rusted; it was submerged in water. Didn't smell it or see it. 20k in damages. We never use it for anything except for groceries in the stroller. The worst decision I have made is bringing it to Toyota, because with it closed up, in the heat, the Van now has as all this mold. Before it was just wet in the 3rd seat compartment. It also had a Frog in it as large as a small hand. Improper storage. Toyota corporation also won't help. Don't be fooled and think this vehicle is imperfect. The new and previous generations have had this problem. They leak from the top and bottom of this door seal. Toyota seams to refuse to make a TSB. You do not have to look far online to find the reported issues. If it can happen to normal people like us doing normal things and many other people like us reporting it, it can and will happen to anyone. A Vehicle less than 3 years old should not be leaking. I have spoken online to other owners experiencing the same. But now since I see Toyota will not assist, and made it worse for us by improperly storing the Van and taking too long to respond. Now we cannot use it and it is a health hazard. Instead of helping me, they instruct me to file a insurance claim I would otherwise not have had to file, if I just air dried the Van. They should have acknowledged the problem and taken the opportunity to improve the design. Not create a mold situation for the customer and tell them to file a claim. This is a quality control issue. [XXX] Before Sienna drop off [XXX] After Sienna Drop off Likely worse now INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

seat retractor failure- white plastic part off and visible , seat is making popping noise when seat is being adjusted. Noticed this when i picked up from dealer after oil change. I feel this is a driving safety concern. Larry H Miller American Toyota (Albuquerque, NM) service manager states it's safe to drive, however I feel this is a huge safety concern. The seat was in working order did not have this issue during drop off of service. However I believe this is a failure on Toyota engineering. I would like some guidance on how to get this repaired as they want me to pay $2,000.
