general problems of the 2015 Toyota Sienna

There is an evap emission leak and the p0456 error states the gas cap is faulty. I had it replaced and replaced again. So I am waiting for another brand new gas cap-3rd brand new one. So 4th overall for this van. A smoke test was done and there is no leaks per the test. So if this continues after the brand new gas cap, then there should be a recall as the gas cap is an issue. Started to happen after 95,000 miles. The awd is shut off and goes to 2 wheel drive, traction control is turned off, check engine light comes on and message check awd system comes up on the screen. Any recommendations.

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. . Read more...

When the car is at idle speed, such as waiting for traffic to clear for a left turn, the car will just die without warning. It will usually restart right away, but this has nearly caused a collision. The dealership in bellevue, wa says that's a normal thing if the car isn't properly maintained. I have brought the car to that dealership for all but one of the maintenance intervals, and the only other time was for maintenance when we were in ohio. Having the throttle body cleaned is not on the routine maintenance schedule. When the car does die there are no codes or other symbols that come up on the display, other than to say that the car died.

Fuel door latch hinge is broken at the top of the hinge. Possibly, it caused by the door latch safety with excessive tension. It disabled the driver side sliding door. Driver's side sliding door could not be opened and it caused exiting issue for children and occupants in the car. Car's mileage is at 27,000 miles. Fuel door opened during in motion and/or stationary.
