We had our van parked on a driveway with a front facing slope, we had hard rains went we where going away there was water coming out of the seat belt on the passenger side and the panel above the window was stained down to the window support where the air bag is. I've been reading reports as far back as 2008 we have a 2020, went taken to the dealer they want 1000 to 2700 to remove the head liner and try to fine the problem, which what was reported didn't help. The dealer recommended to not park with the front of the van facing down hill if rain is forecast, my problem is that Toyota has not been required to fix the leaks. I'm calling my local dealership tomorrow about are leak.

My Toyota sienna is a 2020, has 83,000 miles and has recently been squealing when I accelerate. I took the van to a local body shop and they said it seems to be my transmission. I called Toyota immediately and they knew that the transmissions were faulty and that they would try to work with Toyota to get it fixed. There is no way I can pay 9k for a new transmissions because they put in faulty ones.

The vehicle is a 2020 Toyota Sienna. While driving, the engine suddenly shut off without warning, creating a dangerous situation and loss of power. This occurred while transporting children, increasing the safety risk. A mechanic inspected the vehicle and diagnosed a failure of the low-pressure fuel pump. The problem appears intermittently — sometimes the vehicle runs normally, and other times it stalls or loses power. The check engine light has turned on and off. This issue matches the known defect related to the Denso fuel pump recall affecting many Toyota vehicles from similar model years. However, my VIN is not included in the recall. This is a serious safety concern because the engine can shut off unexpectedly while driving, which could lead to an accident. I believe this vehicle may have the same defective component as those included in the recall, even though it is not currently listed. The issue has been confirmed by an independent mechanic and the vehicle is available for inspection if needed.

The power sliding door assembly failed, and the driver side rear sliding door was bound shut, and could not be opened. Disabling the power door system did not resolve the issue. The cable for the power door mechanism was hanging below the rear vent windows; but for some reason the door still would not open. I ultimately with a lot of gentle force was able to get the door open enough to see the retract side of the cable was bound up, and was able to cut it with wire cutters, and ultimately get the door to work normally as a non-powered manual sliding door. Since the original NHTSA BULLITIN on this was published in 6/2019 before my 2020 Sienna was manufactured, and Toyota did not change the mechanism until the 2021 model redesign, I believe that RECALL should be extend to all 2019 and 2020 vehicles. This seems dangerous that the door does not default to manual operation in error.

"I've owned the vehicle for five years, and recently I started hearing a whining noise coming from the transmission. After doing some research, I discovered that I'm not alone in experiencing this issue. The dealer told me that the transmission itself is the problem and recommended replacing the entire transmission. However, a second opinion suggested that this kind of noise isn't normal. I'm worried about safety because, although it's just a whine right now, I fear it could fail unexpectedly. I have a child in a wheelchair, and ensuring my vehicle's safety is very important to me."
