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. 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.

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 TANK ACCESS DOOR HINGE IS BROKEN. CAN'T FILL GAS TANK UP. IF FUEL DOOR IS REMOVED SLIDING DOOR WON'T OPEN. FUEL DOOR HINGE BROKE BECAUSE THE FUEL DOOR PIN HAS SO MUCH TENSION THAT IT BROKE THE HINGE. THIS CAUSED A SAFETY ISSUE BECAUSE THE DOOR CANNOT BE OPENED FROM THE INSIDE IF IT IS NOT CLOSED ALL THEY WAY OR PUSHED CLOSED ENOUGH FOR THE SENSOR TO ALLOW THE SLIDING DOOR TO OPEN. THIS EVENT WAS REPORTED PAST THE 36 MONTH WARRANTY, (AT 40 MONTHS, BUT LESS THAN THE MILEAGE WARRANTY), BUT HAD BEGUN BEFORE THE WARRANTY HAD ENDED. CURRENT OWNERS SHOULD BE AWARE THAT IF THERE ARE INSTANCES BEGINNING OF THE DOOR NOT BEING ABLE TO BE OPENED, SHOULD CHECK THE HINGE AND PIN TENSION AND HAVE IT FIXED WHILE IT COULD BE UNDER WARRANTY. THIS SHOULD BE AN ITEM COVERED UNDER AN EXTENDED WARRANTY DUE TO THE SAFETY ISSUE OF NOT BEING ABLE TO EXIT THE VEHICLE IN AN EMERGENCY SITUATION. THIS HAPPENED SEVERAL TIMES WHILE PARKED AND EXITING THE VEHICLE. THERE ARE OTHER INSTANCES OF THIS ISSUE ON DIFFERENT SIENNA AND TOYOTA FORUMS. TOYOTA SERVICE MANAGER CONFIRMS THAT IT IS EXCESSIVE, BUT ONLY RESOLUTION WOULD BE TO REPLACE CABLE WITH NO GUARANTEE IT WOULDN'T HAVE EXCESSIVE FORCE ALSO. ONLY OTHER RESOLUTION WOULD BE TO HAVE SERVICE BULLETIN ISSUED BY TOYOTA. YOUR TRACKING NUMBER ASSIGNED BY NHTSA FOR THIS ISSUE IS 11025478.
