REAR MANUAL PASSENGER DOOR IN TOYOTA SIENNA LE (8 PASSAGER) DOES NOT LATCH UNDER CERTAIN CONDITIONS ( WE HAVE NARROWED IT DOWN TO WHEN WINDOWS ARE LEFT OPENED). IN TEXAS DUE TO HEAT CONDITIONS, WINDOWS ARE LEFT OPEN DURING SPRING AND FALL SEASONS. MY DOGS HAVE BEEN STRUCK NUMEROUS TIMES BY "NON-LOCKING" DOORS AND IT HAS ALSO CAUGHT MY HAND ONCE (WHEN PARKED AT AN INCLINE). THIS IS VERY DANGEROUS AND WE HAVE INSTRUCTED OUR KIDS TO ONLY USE THE RIGHT SIDE POWER DOOR DUE TO THIS SAFETY ISSUE. DEALER HAS INDICATED THEY CANNOT FIX THE PROBLEM. FOR A VEHICLE DESIGNED FOR FAMILY USE (INCLUDING KIDS), THIS ISSUE NEEDS TO BE RESOLVED BEFORE KIDS GET HURT.*AK
