1. 2ND ROW DRIVER AND PASSENGER SEATS DO NOT "LOCK" INTO PLACE WHEN FOLDED FORWARD, CREATING A "FREE FLYING" SEAT WHEN DRIVING/IN MOTION AND AN ENTRAPMENT ISSUE WHEN PARKED FOR 3RD ROW PASSENGERS ATTEMPTING TO EXIT THE 3RD ROW. THIS IS SPECIALLY DANGEROUS ON A HILL. MY 3 YEAR OLD HAS BEEN HIT AND INJURED BY THE SEAT ON A SEVERAL OCCASIONS. 2. ENGINE LURCHES AND STALLS WHILE IN MOTION. STALLING CAUSES POTENTIAL RISK FOR ACCIDENT. 3. DRIVER AND PASSENGER SLIDING DOOR WILL NOT OPEN ON OCCASION. THIS MEANS GETTING 2ND AND 3RD ROW PASSENGERS OUT OF TRUNK OR CLIMBING THROUGH TO DRIVER/PASSENGER SEAT. ALL OF THESE HAVE BEEN BROUGHT TO THE ATTENTION OF THE DEALERSHIP, THEY CANNOT REPRODUCE 1 AND 3. HAD NO SOLUTION FOR #2 (A SIMPLE LOCKING ADDITION TO THE SEAT FOOTING WOULD FIX #2, TOYOTA SIENNA'S LOCK ON PLACE)
