THERE ARE 2 POTENTIALLY SERIOUS PROBLEMS THAT THIS VEHICLE HAS, WHICH APPEAR TO BE COMMON, BASED ON COMMENTS FROM 2 OTHER FAMILIES WE KNOW WITH THE SAME PROBLEMS IN THE SAME VEHICLE, A 2001 TOYOTA SIENNA. THE LOCK BUTTON ON THE REAR VAN DOOR GETS STUCK AND APPARENTLY THE ONLY WAY TO FIX IT IS TO BANG ON THE HANDLE UNTIL IT POPS BACK OPEN. WHEN IN THIS POSITION THE DOOR CANNOT BE CLOSED. THE OTHER IS WITH THE IGNITION LOCK; IT STICKS AND LOCKS EVEN AFTER THE WHEEL MAY BE DISENGAGED; THIS LEADS TO A POSSIBILITY OF BEING STRANDED, OR WORSE. *JB

FAILURE CODE P1155 "AIR FUEL SENSOR FAILURE" AT 40K MILES $282.00 FOR JUST THE SENSOR. THE VEHICLE IS LESS THAN 3 YEARS OLD NO HELP OFFERED FROM THE DEALER WITH COST OF REPAIR. FROM MY RESEARCH ON VARIOUS BULLITENS, I FIND THAT TOYOTA HAS HAD NUMEROUS PROBLEMS WITH THIER SENSORS. THE PART NUMBER OF MY FAULTY PART 89467-41040. I OWN TWO 2001 TOYOTA VEHICLES AND ALL SERVICE OIL CHANGES PROVIDED AT DEALER SHIPS. I HAD TWO GM'S AND BECAUSE I HAD MY SERVICE PROVIDED AT THE DEALER THEY TOOK CARE OF THINGS LIKE THIS OUT TO 50K MILES. ATTITUDE LIKE THIS WILL PUSH ME BACK TO GM NEXT TIME. I THINK IT'S ABOUT TIME TO SWAP BACK BECAUSE I AM UPSET WITH TOYOTA'S ATTITUDE!
