2002 Toyota Sienna

Dear Sir, On April 2026, I need to do the semiannual smog check. Right now, I face DTC P0420 error code and I can't pass the smog check inspection. Note that I don't have the engine light on indicating the a/m error code. Only my OBD2 shows the error DTC Code P0420. I did some searhing and noticed that the ECM for Sienna should be updated to erase the a/m DTC code. I would appreciated to help me how the resolve this issue ASAP. It will enable me to renew my registration.You may contact on my cell phone 747 217 7254 or my email at [email protected]. Regards, Massey

CHECKING ENGINE LIGHT ON AND OFF SLIDE DOOR NOT WORKING PROPERLY

THE LOWER REAR MOUNT FOR THE PASSENGER-SIDE REAR SHOCK ABSORBER WAS FOUND WHEN THE VEHICLE WAS STATIONARY TO HAVE BECOME PARTIALLY FRACTURED OVER TIME. IT IS MADE OF THIN HOLLOW METAL WITH INTERNAL THREADS. THERE IS NO REPLACEMENT FOR THIS EXCEPT TO PURCHASE A LARGE MULTI-FUNCTIONAL UNIT COSTING $1,688.00

BRAKES MAKE A NOISE WHEN THE CAR IS ABOUT TO STOP. THERE IS A SQUEAL AND THUMP THAT CAN BE HEARD. HAVE TAKEN THIS IN SEVERAL TIMES TO BE FIXED. THEY SAY THE BRAKES ARE SAFE. I AM 74 YEARS OLD AND HAVE HAD MANY CARS OVER THE YEARS AND THE ONLY TIMES OTHER CARS HAVE MADE THIS KIND OF NOISE IT WAS TIME TO CHANGE THE BRAKES. IN THIS CASE THE BRAKE PADS SEEM TO HAVE PLENTY OF LIFE LEFT. FUNNY THAT WHEN THE REAR DRUMS ARE REMOVED AND THE BRAKE AND DRUMS ARE THOROUGHLY CLEANED THE NOISE DOES NOT HAPPEN FOR A WHILE. THE FIRST COMPLAINT WAS MADE AT 15,523 MILES AND CONTINUES TOO THIS DAY. AT 31,842 MILES THE REAR DRUMS WERE REPLACED PER TSB BR003-04. TOOK THE CAR IN AGAIN AT 125,559 MILES AND WE WERE TOLD WE NEEDED NEW REAR DRUMS. THEY HAD BEEN REPLACED. THEY HAVE A PROBLEM WITH BRAKES AND NEED TO FIX THE PROBLEM.

STEERING GETS STIFF HARD TO TURN STEERING

TL* THE CONTACT OWNS A 2002 TOYOTA SIENNA. WHILE THE VEHICLE WAS PARKED WITH THE ENGINE TURNED OFF AND THE EMERGENCY BRAKE ENGAGED, THE VEHICLE SUDDENLY ROLLED BACKWARDS DOWN A SMALL INCLINE AND CRASHED INTO A FENCE POST. A SMALL CHILD WAS PRESENT INSIDE THE VEHICLE, BUT THERE WERE NO INJURIES. A POLICE REPORT WAS NOT FILED. THE VEHICLE WAS TAKEN TO MAITA TOYOTA (2500 AUBURN BLVD, SACRAMENTO, CA). THE DEALER INDICATED THAT THE TRANSMISSION EXPERIENCED A MECHANISM FAILURE, BUT THE EXACT CAUSE WAS NOT DETERMINED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 136,200.

INCIDENT #1 (6/3/2017) - TOOK FOOT OFF ACCELERATOR PEDAL WHEN TURNING ON CITY STREET. CAR PROCEEDED TO ACCELERATE ON ITS OWN WENT UP TO 35 MPH FOR SEVERAL BLOCKS INCIDENT #2 (6/4/2017) - WHILE PARKING CAR IN DRIVEWAY, APPLIED FOOT ON BRAKE PEDAL. ENGINE ROARED AND THRUSTED FORWARD.

THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 24,000. ...UPDATED 09/12/16 *BF THE CONSUMER STATED THE VEHICLE WAS REPAIRED UNDER AN EXTENDED WARRANTY. *JS

THE CABLE FOR THE PASSENGER POWER DOOR SNAPPED AND DOOR WOULD NOT FULLY SHUT. I WAS STOPPED, GETTING READY TO TURN LEFT, WHEN IT SNAPPED.

THE ELECTRIC SLIDING DOOR MECHANISM BROKE DOWN . IT OPEN BUT IT DOESN'T CLOSE. IT GETS STOCK.

WHEN I ATTEMPTED TO OPEN DRIVER SIDE SLIDING DOOR IT WOULD NOT OPEN ELECTRICALLY OR MANUALLY. AFTER SEVERAL FAILED ATTEMPTS TO OPEN I CUT THE CABLE AND WAS ABLE TO THEN OPEN THE DOOR. AT THIS POINT IN TIME BOTH SLIDING DOORS WILL NOT OPEN ELECTRONICALLY BUT WILL OPEN MANUALLY. *TR

DOOR HANDLES BREAK OFF DURING NORMAL USE DUE TO ELECTRICAL DOOR MALFUNCTION. THE DESIGN OF THESE DOOR HANDLES ARE POOR AND A NEW DESIGN NEEDS TO BE MADE. *TR

ALL THE LOCKS KEEP UNLOCKING, AND LOCKING WITHOUT ANYONE IN OR AROUND THE VEHICLE, BECAUSE LOCKS ARE LOCKING AND UNLOCKING IT IS CAUSING THE BATTERY TO DRAIN. THE DOORS LOCK AND UNLOCK WHILE VAN IS IN GEAR, WHILE DRIVING, AND WHEN VAN IS NOT RUNNING WITHOUT KEY IN IGNITION. I HAVE 2 CHILDREN AND BELIEVE THIS IS A SAFETY ISSUE! *TR

I BACKED OUT OF MY DRIVEWAY ONTO THE ROAD. I SHIFTED FROM REVERSE TO DRIVE. I PUT MY FOOT ON THE GAS PEDAL AND DID NOT EXPERIENCE TYPICAL ACCELERATION. I TOOK MY FOOT OFF THE GAS PEDAL COMPLETELY. THEN I PUT MY FOOT BACK ON THE GAS PEDAL AND PUSHED DOWN HARDER THAN NORMAL TO SEE IF I GOT A RESPONSE. AT THIS POINT THE ENGINE BEGAN TO REV. THEN I HAD TO PUT MY FOOT ON THE BRAKE TO PREVENT THE CAR FROM MOVING FORWARD. EVEN WITH MY FOOT ON THE BRAKE THE ENGINE CONTINUE TO REV AND THE CAR WAS STILL MOVING FORWARD. I PUT THE CAR IN NEUTRAL AND WITH MY FOOT OFF THE GAS PEDAL THE ENGINE CONTINUE TO REV. I THEN DEPRESSED THE GAS PEDAL WITH MY FOOT BRIEFLY AND TOOK MY FOOT OFF AND THE ENGINE STOPPED REVVING AT THIS POINT. I PUT IT IN DRIVE AND HAD NO PROBLEMS WITH IT AFTER THAT POINT. WHILE THE VEHICLE WAS REVVING MY LEFT FOOT WAS NOT TOUCHING OR NEAR THE GAS PEDAL. THE FLOOR MAT WAS NOT IN THE WAY. AND MY RIGHT FOOT WAS FREE AND UNENCUMBERED. THERE WAS NO TRAFFIC AROUND ME SO I WAS ABLE TO FULLY CONCENTRATE ON THE ISSUE AND DID NOT HIT ANYONE OR ANYTHING. *TR

WHEN DRIVING ON CRUISE CONTROL AND LIGHTLY BRAKING THE CAR SUDDENLY ALARMINGLY ACCELERATES. DEALER CLAIMS VARIOUS ISSUES THAT THEY TRIED BUT NON RESOLVED THE PROBLEM. I AM READY TO SELL AND AFRAID THAT THE BUYER MIGHT NOT REMEMBER TO FOLLOW MY INSTRUCTION TO TURN OFF THE CRUISE CONTROL BEFORE BRAKING. I HAVE BROUGHT THE CAR TO THE DEALER SEVERAL TIMES OVER THE YEARS, MOST RECENTLY THIS YEAR 2014. *TR

OUR 2002 TOYOTA SIENNA HAD THE GEAR SHIFT REPAIRED AT A MAJOR ATLANTA AREA TOYOTA DEALER ON MAY 5, 2014. THE GEAR SHIFT REPLACEMENT REQUIRED THE ENTIRE STEERING COLUMN TO BE DISASSEMBLED. ABOUT ONE WEEK AFTER THAT REPAIR, THE STEERING COMPLETELY FAILED. THE STEERING WHEEL TURNED WITH ABSOLUTELY NO CONTROL OF THE WHEELS. BY SHEER LUCK THIS STEERING FAILURE OCCURRED IN A PARKING LOT AFTER JUST TRAVELING ON THE INTERSTATE. HAD THIS STEERING FAILURE OCCURRED AT INTERSTATE SPEEDS, THIS MAY HAVE BEEN FATAL. THE VEHICLE WAS RETURNED TO THE SAME MAJOR ATLANTA AREA TOYOTA DEALER AND THE CAUSE OF THE STEERING FAILURE WAS IDENTIFIED AS "STEERING JOINT BOLT BACKED OFF FROM CONNECTION". I WAS TOLD THAT THE STEERING FAILURE WAS CAUSED BY ONE BOLT COMING LOOSE. THE STEERING FAILURE WAS CORRECTED BY "RE-TIGHTENED' BOLT WITH LOCK TIGHT". IN SUMMARY, THE REPAIR OF A GEAR SHIFT BY A CERTIFIED TOYOTA DEALER SERVICE CENTER RESULTED IN COMPLETE STEERING FAILURE DUE TO ONE BOLT THAT "BACKED OFF FROM CONNECTION" OR THAT WAS NOT PROPERLY TIGHTENED OR SECURED. IT IS VERY CONCERNING THAT TOYOTA?S STEERING COLUMN DESIGN HAS THE POTENTIAL TO CAUSE COMPLETE STEERING FAILURE WHEN ONE BOLT COMES LOOSE. IT IS ALSO A MAJOR ISSUE THAT A CERTIFIED TOYOTA DEALER SERVICE CENTER IS UNABLE TO SAFELY DISSEMBLE AND REASSEMBLE THE STEERING COLUMN AND PROVIDE A SAFE AND DRIVABLE VEHICLE. I WOULD LIKE TO FIND OUT HOW OFTEN THIS TYPE OF STEERING FAILURE HAS OCCURRED ON THIS AND SIMILARLY DESIGNED TOYOTA VEHICLES. I WOULD ALSO LIKE TO KNOW HOW MANY CRASHES, SERIOUS INJURIES OR DEATHS HAVE RESULTED FROM THIS ISSUE. THIS CERTAINLY CAN?T BE THE ONLY OCCURRENCE. I FEEL IT IS IMPERATIVE TO ALERT OWNERS OF THIS VEHICLE AS WELL AS AUTHORIZED REPAIR CENTERS OF THE SITUATION OR ISSUE A RECALL TO ENSURE THAT THE STEERING JOINT BOLT IS SECURE.

THATS BY I WANT TO NO IF IS COVER FOR THE WARRANTY OR RECALL. *TR

EVER SINCE NOVMBER, 2008, MY 2002 TOYOTA SIENNA PASSENGER SIDE POWER DOOR, HAS INTERMITTENTLY FAILED TO OPEN EITHER BY ACTIVATING THE BUTTON ON THE INSIDE OF THE DOOR COLUMN, BY PULLING THE DOOR HANDLE OUTSIDE, OR THE INSTRUMENT PANEL DOOR BUTTON, OR WORSE, AFTER OPENING, WILL NOT CLOSE. THE DEALER HAD TO REINITIALIZE THE ECU IN NOVEMBER, 2008, AND HAVE HAD INTERMITTENT PROBLEMS SINCE. NOW, SINCE AT LEAST DECEMBER, 2012, THE SLIDING DOOR WILL NOT OPEN AT ALL BY ANY OF THE 3 METHODS AND CANNOT BE REINITIALIZED. ALSO, AT TIMES THE MANUAL DRIVERS SIDE PASSENGER DOOR, IN THE PAST ~ 1 1/2 YEARS WILL NOT OPEN EITHER FROM INSIDE DOOR BUTTON RELEASE OR OUTSIDE DOOR HANDLE AND PASSENGERS HAVE TO CLIMB OVER FROM THE FRONT SEATS TO ENTER OR CLIMB OVER THE FRONT SEAT & CONSOLE TO EXIT THE VEHICLE. I HAVE BEEN ADVISED BY MY LOCAL TOYOTA DEALER THAT I NEED TO "START WITH THE REPLACEMENT OF THE ECU," A PART COSTING $730.00 AND ABOUT $1000 WITH INSTILLATION. I HAVE READ OTHER HORROR STORIES THAT REPLACING THE ECU ISN'T NECESSARILY THE ANSWER AND MANY DON'T KNOW WHAT THE ANSWER IS. HAVE THERE BEEN ANY AUTO RECALLS ON THESE POWER DOOR MECHANISMS YET? I SEE A LARGE VOLUME OF THE EXACT SAME COMPLAINTS ON THE INTERNET FOR THESE SIENNA AS WELL AS WITHIN THE NHTSA DATABASE. IN THE EVENT OF AN EMERGENCY EVACUATION OF THE VEHICLES' PASSENGERS, AS IT STANDS, A CATASTROPHE IS WAITING TO HAPPEN. *TR
