2012 Toyota Sienna complaints

I HAVE BROUGHT THE SIENNA INTO TOYOTA ON 3 SEPARATE OCCASIONS, AS THERE WAS CLUNKING WHEN THE LIFT GATE CLOSED. I WAS TOLD THERE WAS NOTHING WRONG WITH IT EACH TIME, BUT THE LIFTGATE WAS AND IS CLEARLY NOT ALIGNED. WATER IS NOW COMING THROUGH THE TOP OF THE LIFT GATE. I DID BACK UP INTO A TREE, AND HAD DAMAGE TO THE BACK QUARTER PANEL AND IT WAS REPAIRED BY A BODY SHOP. TOYOTA IS STATING THAT THIS CAUSED THE LIFTGATE TO BE MISALIGNED AND THAT IS CAUSING THE WATER TO COME THROUGH THE LIFTGATE. MY COMPLAINT IS I BELIEVE THAT DEALERSHIP IS AVOIDING REALIGNING THE LIFT GATE. I ORIGINALLY BROUGHT THIS IN UNDER THE MANUFACTURER WARRANTY AND I HAVE AN EXTENDED WARRANTY. THERE WAS NO VEHICLE DAMAGE TO THE VAN UPON INITIAL VISIT. AT THIS POINT, IF THE LIFTGATE IS NOT REALIGNED AND FIXED PROPERLY AND WATER CONTINUES TO COME IN, IT WILL EVENTUALLY DESTROY THE MECHANISM THAT IS USED FOR THE AUTO OPEN AND CLOSE. IN ADDITION, I AM ALSO CONCERNED ABOUT THE OVERALL SAFETY OF THE VEHICLE IN THE EVENT OF AN ACCIDENT, IF WHAT TOYOTA STATES IS TRUE (THE LIFTGATE CAN BE MISALIGNED BY QUARTER PANEL DAMAGE).

ALL UNDERWOOD COMPONENTS ARE NOT ONLY VULNERABLE, BUT ATTRACTIVE TO RODENTS. WHILE PARKED OVERNIGHT ON 4 CONSECUTIVE NIGHTS, RODENTS HAVE CHEWED THROUGH WIRES DESPITE ATTRACTIVE RODENT POISON IN THE ENGINE BAY, THE POISON IS UNTOUCHED AND THE WIRES ARE ATTACKED EVERY NIGHT. TO DATE INJECTOR WIRES, SENSOR SIRES, FUEL PUMP WIRES HAVE BEEN COMPROMISED, INCLUDING SENSORS FOR THE STABILITY CONTROL SYSTEM, WHICH IS DISABLED. I REPAIRED DAMAGE BY RUNNING NEW WIRES, CLEARING NESTS AND SET TRAPS AND POISON, BUT NOW THE THE FUEL SYSTEM HAS BEEN ATTACKED AND THE FUEL PUMP DOES NOT ACTIVATE. 3 OTHER CARS PARKED IN THE SAME LOCATION FOR THE PAST 5 MONTHS ARE UNTOUCHED. SAFETY SYSTEMS ARE LIKELY TO BE COMPROMISED FOR ANY PERSON WHO MUST PARK THESE OUTDOORS.

I OWN A 2012 SIENNA WITH APPROXIMATELY 34,000 MILES. THE WHEELS ARE ALUMINUM, AND THE TIRES HAVE ALL RECEIVED ROUTINE ROTATIONS AT THE DEALERSHIP, AND TIRE REPAIRS AT THE LOCAL TIRE DEALER, ALL OF WHICH INVOLVED THE USE OF AIR DRIVEN IMPACT WRENCHES. IMPACT WRENCHES HAVE DAMAGED THE TWO PIECE CHROME PLATED PROTECTIVE COVERING ON MOST OF THE LUG NUTS ON MY WHEELS TO THE POINT THAT THEY LITERALLY CANNOT BE REMOVED OR REINSTALLED USING THE FACTORY SUPPLIED LUG WRENCH. THE WRENCH NO LONGER FITS THE DAMAGED LUG NUTS. TWICE RECENTLY I HAVE HAD FLATS, REQUIRING THE USE OF THE FACTORY SUPPLIED LUG WRENCH TO REMOVE THE FLAT AND INSTALL THE SPARE. THIS TASK WAS IMPOSSIBLE BOTH TIMES BECAUSE OF EXISTING DISFIGUREMENT TO ONE OR MORE OF THE LUG NUTS ON THE WHEELS INVOLVED. I HAD TO GET HELP FROM TIRE SHOPS BOTH TIMES TO CHANGE MY TIRES. FORTUNATELY BOTH TIMES HELP WAS AVAILABLE, BUT WITHOUT SUCH HELP, A SIMPLE FLAT TIRE CAN STRAND MOTORISTS, SUBJECTING THEM TO EXTREME SAFETY HAZARDS WITH TERRIBLE POTENTIAL SAFETY CONSEQUENCES. ONCE REMOVED, LUG NUTS CANNOT BE RELIABLY RETIGHTENED.

2012 SIENNA LIMITED ELECTRICAL ISSUES I HAVE A 2012 TOYOTA SIENNA LIMITED WITH EVERY OPTION EXCEPT AWD. ON FEBRUARY 4, 2015, AFTER DRIVING FOR ABOUT 25 MINUTES, WHEN I STOPPED AND TURNED OFF THE ENGINE, THE VAN COMPLETELY DIED! I WANTED TO START AGAIN, BUT THERE WAS NO POWER AT ALL; NOTHING WOULD FUNCTION, DOOR LOCKS, RADIO, LIGHTS, NOTHING! I HAD TO WAIT FOR ABOUT 5 MINUTES. FINALLY I WAS ABLE TO START; HOWEVER THE NAVIGATION DVD WAS RESET. THIS IS THE SECOND TIME IT HAPPENS THIS WEEK. BEFORE THESE EVENTS; ABOUT ONE YEAR AGO SOMETHING LIKE THAT HAPPENED, THAT TIME THE VAN WAS IN THE GARAGE, WE WERE READY TO GO TO CHURCH AND WHEN I PRESS THE START BUTTON IT TRIED TO START BUT THEN IT COMPLETELY DIED, THERE WAS NO POWER AT ALL. I AM REALLY CONCERNED THAT THIS WILL HAPPEN WHILE DRIVING AND WE WILL BE IN A VERY SERIOUS CONDITION NOT BEING ABLE TO CONTROL THE VEHICLE. I ALREADY CALLED THE DEALER, BUT THERE WAS NO HELP. I HAD THE BATTERY CHECKED AND IT?S IN PERFECT CONDITIONS! *TR

I WANT TO CORRECT THAT ON OUR 2012 SIENNA IT IS THE BACK SLIDING DOOR THAT IT IS THE "HINGE" THAT OPENS AND SHUTS THE DOOR, LOCKS IT, ATTACHES IT TO THE VAN THAT IS STARTING TO RUST. TOYOTA REPLY IS TILL IT FALLS OFF, OR STARTS TO "BE MORE RUSTED, BUT NOT IN OUR LIFETIME" IT IS COSMETIC, YET IT IS DANGEROUS AND WILL AFFECT THE RESALE VALUE AND IT IS NEAR THE WIRES THAT OPEN AND SHUT IT, WHICH I HAVE READ PROBLEMS ABOUT. TOYOTA SHOULD TAKE RESPONSIBILITY FOR THE HINGES RUSTING AND REPLACE THEM BEFORE SOMEONE DOES GET HURT, YOU JUST DON'T WAIT FOR THE ACCIDENT TO HAPPEN OR TILL SOMEONE GETS HURT. *TR

TODAY WHILE CLEANING THE VAN, I NOTICED THE LEVER AND/OR LATCH THAT HOLDS THE BACK SLIDING DOORS AND MOVES THEM OPEN AND SHUT, KEEPS THE BACK SLIDING DOORS ON, IS STARTING TO RUST WHERE THE DOOR IS CONNECTED NEAR THE CABLES THAT OPEN AND SHUT THE DOOR. *TR

AFTER THE WEATHER DROP TO 45 DEGREES ON OCTOBER 5, 2014 I STARTED MY 2012 TOYOTA SIENNA (AWD), I IMMEDIATELY NOTICE THAT ALL LIGHT IN THE PANEL WERE ON. THERE IS WARNING IN CENTER VIEW PANEL ALERTING ME THAT I NEED TO TAKE THE VEHICLE TO DEALERSHIP FOR ABS, VSC AND BRAKE SYSTEM PROBLEM. THE FOLLOWING DAY I DROVE THE VEHICLE TO THE DEALERSHIP AND NOTICE THAT THE SPEEDOMETER AND GAS GAUGE ARE NOT WORKING. THE SPEEDOMETER HAND IS MOVING BACK AND FORTH. THE GAS IS ALWAYS IN THE FULL MODE. I ALSO NOTICE THAT THE BRAKE IS ALWAYS IN ON MODE. DRIVING WITHOUT WORKING SPEEDOMETER, BRAKE SYSTEM AND GAS RANGE ARE REALLY PUTTING MY LIFE IN DANGER. I AM HOPING THAT MY DEALERSHIP WHICH SUPERIOR TOYOTA CAN FIX THESE PROBLEM. I AM ALSO HOPING THAT WARRANTY WILL COVERT THE DEFECTIVE PART. *TR

I AM COMPLAINING ABOUT THE MICHELIN PRIMACY MXV4 TIRES. THE TIRES HAVE A 60,000 MILE WARRANTY AND I HAVE ONLY GOTTEN 20,200 MILES OUT OF THEM. THE TREAD WEAR IS A 5/6 GAUGE. I WILL HAVE TO PURCHASE THREE NEW TIRES VERY SOON, BEFORE THE TIRES START BALDING, IN ORDER TO CORRECT THERE FAILURE. I STARTED OUT WITH FOUR OF THEM, BUT NOW I AM DOWN TO THREE. ONE OF THEM HAD A SCREW FOUND IN IT, SO I REPLACED IT WITH A NEW FIRESTONE TIRE. *TR

THE PERSON SIT BEHIND THE DRIVER, PUSH THE AUTOMATIC VAN DOOR CLOSE BUTTON TO CLOSE THE DOOR THEN REACHED OVER FOR THE SEAT BELT. THE PERSON ACCIDENTALLY REACH THE HAND BETWEEN THE SLIDING DOOR AND DOOR FRAME RIGHT NEXT TO THE SEAT BELT ANCHOR CLOSE TO THE DOOR. THE DOOR CLOSED ON THE OPEN FINGER AND TRIED TO CLOSE EVEN TIGHTER. THE DOOR MECHANISM DID NOT REVERSE AND OPEN THE DOOR BACK UP, BUT CONTINUES TO TRY TO CLOSE THE DOOR COMPLETELY. AFTER SOME HARD PULL ON THE DOOR HANDLE, THE DOOR FINALLY REOPENED. THE PERSON FINGER WAS BRUISED AND THE WEDDING RINGS SHAPE HAS BEEN DAMAGED. THE RING IS NO LONGER ROUND NOR STRAIGHT, IT HAS BEEN TORQUED BY THE FORCE OF THE DOOR MECHANISM. *TR

(REAR POWER SLIDING DOORS: NO SAFETY SENSORS TO STOP THE DOOR ) I PULLED THE HANDLE OF THE REAR POWER SLIDING DOOR TO OPEN TO LET MY DOG OUT. SHE PUT HER HEAD INTO THE OPENING BETWEEN THE TRACTOR CABLE THAT GLIDES THE DOOR BACK AND THE REAR PORTION OF THE DOOR. THE POWER DOOR CONTINUED TO SLIDE BACK AND INWARD. MY REPEATED ATTEMPTS TO STOP THE DOOR INCLUDED ME PULLING AGAINST IT WITH ALL MY STRENGTH THE DOOR JUST KEPT SLIDING EITHER BACK OR FORWARD. MY DOG TRIED TO SQUEEZE HERSELF OUT AND ONLY MANAGED TO GET HALF HER BODY OUT. SHE LOOKED LIKE SHE WAS CUT IN HALF. MY NEIGHBORS CAME OVER AND HELD THE DOOR TO STOP IT FROM MOVING. THE SPACE BETWEEN THE BODY OF THE VAN AND THE SLIDING DOOR WAS SO TIGHT (3 TO 4 INCHES), I COULD NOT PUSH OR PULL MY DOG OUT. I THOUGHT SHE WAS BEING CRUSHED TO DEATH. I WENT TO DISENGAGE THE BATTERY TO MAKE SURE THE DOOR WOULD NOT MOVE AND MY DOG WAS ABLE TO WRIGGLE HER ENTIRE BODY OUT OF THAT TINY OPENING. THIS LASTED FOR ABOUT 10 MINUTES AND WAS TERRIFYING. MY DOG SUFFERED ONLY BRUISED RIBS. I HAD A CHRYSLER TOWN AND COUNTRY BEFORE THIS AND THE DOOR SENSORS STOPPED AT THE SLIGHTEST INTERFERENCE. THIS IS AN INCREDIBLE SAFETY HAZARD. *TR

DRIVER'S SIDE REAR SLIDING DOOR WILL NOT LATCH SHUT WHEN CLOSING DOOR EITHER MANUALLY OF ELECTRICALLY. WHEN CLOSING FRONT LATCHES ENGAGE OF SLIDING DOOR BUT SUBSEQUENT REAR LATCHING DOES NOT ENGAGE UPON END OF CLOSING CYCLE. ONE CAN HEAR REAR OF SLIDING DOOR LOCKING MECHANISM ACTUATOR WHINE WHEN ATTEMPTING FINAL CLOSE CYCLE. AFTER THE VAN'S FAILURE TO CYCLE THE DOOR SHUT AT REAR, THEN ALSO AT REAR A DIAGNOSTIC SOUNDS A LONG BEEP WARNING SOUND AFTERWARDS. REMOVING NEGATIVE TO SEE IF THIS WOULD RESET THE DOOR IN SOME WAY ONLY SERVED TO CANCEL ALL ELECTRONIC COMMANDS TO THE DOOR TO OPEN OR CLOSE USELESS FROM ANY BUTTON (FOB, OVERHEAD CONTROL CONSOLE BUTTON, MANUAL DOOR HANDLE OPENING OR OPEN/CLOSE BUTTONS). PASSENGER (RIGHT) SLIDING DOOR UNAFFECTED. *TR

IN NOV 2013, THE BATTERY LIGHT ON THE DASHBOARD TURNED ON. WITHIN A FEW MINUTES OF THAT HAPPENING, THE VEHICLE STALLED WHILE DRIVING AND WOULD NOT MOVE AGAIN. THE VEHICLE WAS TOWED TO THE DEALER, WHERE THE DEALER DISCOVERED THAT THE CAR?S ALTERNATOR NEEDED TO BE REPLACED. IN JAN 2014, THE BATTERY LIGHT TURNED ON AGAIN, SO I DROVE THE VEHICLE BACK TO THE DEALER, WHERE THEY CLAIMED THAT THE PROBLEM WAS ONCE AGAIN WITH THE ALTERNATOR. THEY REPLACED THE SIENNA?S ALTERNATOR AGAIN. IN MAR 2014, THE BATTERY LIGHT CAME ON YET AGAIN. I BROUGHT IT INTO THE DEALER FOR A THIRD TIME, BUT THIS TIME THE DEALER CLAIMED TO BE UNABLE TO FIND ANY PROBLEMS WITH THE CAR?S ELECTRICAL SYSTEM. HE RETURNED IT TO ME WITH ADVICE TO BRING IT BACK IN IF THE PROBLEM CONTINUED. AFTER THE THIRD DEALER VISIT FOR THE BATTERY LIGHT ISSUE, WE STILL SAW THAT THE BATTERY LIGHT WOULD LIGHT UP ON SEVERAL OCCASIONS. THE DEALER MADE IT CLEAR THAT I SHOULD ONLY BRING IN THE CAR IF THE BATTERY LIGHT WAS ON SO THAT THEY COULD DIAGNOSE THE PROBLEM. HOWEVER, THE INTERMITTENT TIMES THAT IT WAS ON WOULD NOT LINE UP WELL WITH THE DEALER?S REPAIR SHOP?S SCHEDULE. I HAVE RECORDED VIDEO EVIDENCE THAT THE CAR EXHIBITS THE BATTERY LIGHT ISSUE OUTSIDE OF DEALER HOURS AND SENT IT BACK TO TOYOTA. I HAVE TRIED TO CONTACT TOYOTA THROUGH BOTH THE DEALER AND DIRECTLY. I HAVE EVEN FILED A CLAIM THROUGH CALIFORNIA'S LEMON LAW. TOYOTA DENIED MY CLAIM, SAYING THAT THEY CONFORMED MY VEHICLE TO THE TERMS OF THE WARRANTY WITHIN A REASONABLE NU

BRAND NEW TOYOTA SIENNA. THE MOONROOF/SUNROOF KEEPS LEAKING. BEEN TO THE DEALER MULTIPLE TIMES AND WHEN WE COME BACK THE ADVISER ALWAYS TELLS US THE VAN WON'T LEAK ANYMORE ONLY TO FIND OUT THE NEXT TIME IT RAINS, THE CAR LEAKS AGAIN. WE DON'T KNOW EXACTLY WHEN THIS STARTED HAPPENING( WE GUESSED IT LEAKED A LONG TIME AGO DUE TO THE RUSTED PARTS AROUND THE GLASS) SINCE NO ONE REALLY SITS IN THE BACK. THE DEALER ALREADY REPLACED THE GLASS AND THE RUBBER SEALS AROUND IT. *TR

TL* THE CONTACT OWNS A 2012 TOYOTA SIENNA. THE CONTACT STATED THAT WHILE DRIVING 50 MPH, AN UNKNOWN OBJECT FRACTURED THE WINDSHIELD AND GLASS SHATTERED ALL OVER THE CONTACT. THE CONTACT ALSO STATED THAT THERE WAS A TWO FEET WIDE CRACK ON THE OUTSIDE LAYER OF THE WIND SHIELD, HOWEVER THE INSIDE LAYER OF THE GLASS WAS SHATTERED. THE POLICE REPORT WAS NOT FILED AND THERE WERE NO INJURIES REPORTED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 50,000.

WHEN BRAKING AT NORMAL SPEEDS ON THE ROAD OR THE FREEWAY, THE CAR VIBRATES/SHAKES. ACCORDING TO THE DEALERSHIP THE ROTORS ARE WARPED. AT 12,000 MILES, THIS SEEMS TO BE AN UNDER-ENGINEERED PART ON THIS HEAVY VAN, WHICH APPEARS TO BE UNCORRECTED ON THE NEWER MODEL (2013 AND 2014) AS WELL. THE REPAIRS ARE NOT COVERED UNDER WARRANTY. THE ONLY OTHER OPTION IS TO INSTALL AFTERMARKET HEAVY-DUTY ROTORS, AN EXPENSE THAT THE CONSUMER SHOULD NOT HAVE TO PAY. *TR

WE FIRST ENCOUNTERED A PROBLEM IN WHICH THE AUTOMATIC SLIDING DOOR WOULD NOT FUNCTION TO OPEN OR CLOSE AUTOMATICALLY BUT IT STILL WORKED MANUALLY. ABOUT A WEEK LATER THE REAR LATCH OF THE PASSENGER SLIDING DOOR BECAME STUCK IN THE LOCK POSITION THUS NOT ALLOWING THE DOOR TO FULLY CLOSE. I TOOK THE VEHICLE TO MY MECHANIC WHO GREASED THE LATCH AND ALLOWED IT TO FUNCTION PROPERLY HOWEVER THE DOOR WOULD STILL ONLY OPEN AUTOMATICALLY BUT WOULD OPEN OR CLOSE MANUALLY JUST FINE. DURING THIS TIME THERE WERE 3 INSTANCES WHEN THE DOOR WOULD AUTOMATICALLY OPEN WITHOUT HUMAN INTERVENTION BUT WHILE WE WERE DRIVING DOWN THE HIGHWAY WITH CHILDREN IN THE REAR SEATS. TOYOTA AGREES THIS IS A MAJOR SAFETY ISSUE BUT WILL ONLY SPLIT THE $1,200 BILL WITH US. BASED ON THE FACT THEY ARE WILLING TO HELP PAY FOR THE REPAIR OUT OF WARRANTY PROVES THEY ARE AWARE OF THE ISSUE YET FAIL TO ISSUE A RECALL AND PUT ARE WILLING TO RISK LIVES ESPECIALLY CHILDREN'S LIVES TO SAVE FACE. *JS

2012 TOYOTA SIENNA HAD TWO FRONT-WHEEL BLOWOUTS IN LESS THAN ONE YEAR. TIRES HAD LESS THAN 25,000 MILES IN BOTH INSTANCES. *TR

2012 TOYOTA SIENNA. CONSUMER WRITES IN REGARDS TO ACCELERATION PROBLEMS. *SMD THE CONSUMER STATED THE VEHICLE STARTED TO STALL. THE MORE SHE ATTEMPTED TO ACCELERATE, THE SPEEDOMETER CONTINUED TO DECREASE. SHE WAS ABLE TO PULL OFF TO THE SHOULDER. HER HUSBAND ATTEMPTED TO RE-START THE VEHICLE, BUT NOT HAPPENED. THE VEHICLE WAS TOWED TO THE DEALER. HOWEVER, A COMPUTER DIAGNOSTIC DID NOT REVEAL A PROBLEM. SEVERAL DAYS LATER, THE VEHICLE STALLED AGAIN. SHE MANAGED TO RE-START THE VEHICLE, AND DROVE IT TO THE DEALER. AFTER HAVING THE VEHICLE FOR SEVERAL DAYS, THE DEALER WAS STILL UNABLE TO FIND A PROBLEM. THE VEHICLE WAS RETURNED TO THE CONSUMER. HOWEVER, IT STALLED AGAIN, AND IT WOULDN'T RE-START. THE VEHICLE STALLED AGAIN, FOR THE 4TH TIME.*JB THE CONSUMER STATED THE TECHNICIANS QUICKLY FOUND THE PROBLEM, WHICH WAS A FAULTY WIRE LEADING TO THE FUEL PUMP. UPDATED 05/20/14

THE ENGINE WAS OFF. I OPENED THE REAR HATCH, WHILE I WAS UNDER THE HATCH PLACING ITEMS IN THE BACK OF THE CAR MY HUSBAND NOT REALIZING I HAD ALREADY OPENED IT AND WAS UNDER IT PUSHED THE BUTTON TO OPEN THE HATCH BUT SINCE IT WAS ALREADY OPEN IT STARTED TO CLOSE ON ME. UPON MEETING RESISTANCE FROM ME (SUBSTANTIAL I MIGHT ADD) IT DID NOT STOP CLOSING AND I HAD TO JUMP INTO THE REAR OF THE VEHICLE TO PREVENT BEING SERIOUSLY INJURED. EITHER THERE IS NO SENSOR TO SENSE AN OBSTRUCTION IN THE DOOR OR THE SENSOR IS FAULTY. WE WILL NOTIFY THE DEALER OF THIS BUT THIS IS A SENSOR THAT SHOULD NOT FAIL, THIS DOOR IS BIG ENOUGH TO SERIOUSLY INJURE SOMEONE OR KILL A CHILD. I WAS NOT INJURED SERIOUSLY BUT MY NECK AND SHOULDER ARE SORE AT THIS POINT FROM PUSHING BACK ON THE DOOR AND TIME WILL TELL IF IT IS MORE THAN A MINOR STRAIN. *TR
