2015 Toyota Sienna

Water intrusion from front sunroof when vehicle is parked at a 5% grade with the nose downward. Multiple vehicles exhibit this issue. Toyota is not creating any TSB and will mot even remedy it even if we have an extended warranty. Here is a link to the discussion thread: [XXX] I have not posted on this thread but I have the exact same issue for years. Toyota dealerships want me to first pay $1000 in labor to pull down the headliner and test. Then ask the warranty to cover the assembly, if they don't cover it... then I am on the hook for the work. The missing seam sealer is a common issue that will not manifest inside the 3yr / 36k mile warranty. My issue started around 2020 that I noticed and every dealership would not help me other than place a large burden on me. This can impact the electrical and the airbag curtains. The issue needs to have a seal sealer added to the sunroof assembly as the fix. As a family vehicle, this is a dangerous issue for multiple occupants in a single 7 or 8 person hauler minivan. Please ask Toyota remedy this issue that has been going on for over a decade. Please ask them to stop forcing customers to have sunroofs and panoroofs... when they can't build it correctly.

This vehicle is a tire eater. It does not matter what the brand of tire it is- Michelin, Bridgestone, or Yokohama, tires last, at best, 18 months of local soccer mom driving. After five sets of 50K mile, or better rated tires, at $800 to $1200 hundred per set, I think it is time that Toyota owns up to the fact that something is wrong with this model (4x2) vehicle. In my mind thjis is similar to the Toyota airbag situation only on a smaller scale. The manufacturer always has an out, such as, did the customer have the vehicle aligned, have the tire pressure checked, rotate tire on schedule, was it driven off road? My concern is that just about any driver would expect to get 30 to 40 thousand miles of normal driving from a set of premium tires. If the tires wear abnormally quickly while expecting "normal" tire mileage, this puts the driver in danger due to unexpected tire failure and possible tire related accident. This needs some data analysis.

Door to gas tank fill breaking off. Very common problem noted online by several owners of this vehicle. If it does not close properly the engine will not start. As it begins to break at the hinge the door sticks out. I fear it will fall off one day. Dealer acknowledges this is a problem and knows there is no recall for it. I have seen other exact vans that the door has been removed completely.

Due to poor design, air system intakes (eg under front seats) and outlets have not been protected by grilles, allowing intrusion of rodents into air system blower motor and heat box. I had rodent feces in my air filter system and blower motor and dead rodents in my heat box in Oct 2022 and has recurred in Feb 2023. Rodent intrusion in air system presents serious risk of respiratory illness to humans. Rodent infestation in vehicle can also cause startling to driver which presents an additional safety risk. Air system access should be protected by grilles at all inlet and outlet points.

My vehicle had been repaired for the recall involving the power sliding doors. The entire cable assembly was replaced. That repair has now failed and the sliding door is inoperable. The cable snapped and the driver side door will not open. I am afraid that it may open while driving, which caused the recall in the first place. I don't want to drive the vehicle for fear of the other sliding door failing as well. These repairs should last much longer than 5 years, especially something as important as the sliding door, where all the children sit. What a huge safety issue for what is supposed to be a vehicle for hauling children around. Luckily the incident happened in a parking lot.

On a warm day after driving the van about 15 minutes then stop for 15 minutes or more. It is taking longer than usual to crank the van. I have search around online. It seems like a common problem Sienna's fuel pump. People on "SiennaChat - https://www.siennachat.com/threads/engine-starts-great-cold-or-hot-long-crank-when-warm.59549/page-2 " website is talking about it. My concern is that one day it could stall while driving on the highway. Since, it is fuel related issues. Without fuel supply engine will halt.

We got into an accident today, and none of the sliding doors would not slide open. It would not even allow us to pull the doors opens. The vehicles electrical was damaged, but that should not prevent the other doors from opening. This is a very bad situation if someone is needing to evacuate the vehicle. The rear passengers would be trapped. Please address this issue with Toyota asap. People who usually have Vans have big families and small children. This would be a very bad situation if vehicle needed to be evacuated asap. The rear passengers would be stuck.
