DOORS WILL NOT OPEN EVEN AFTER RECALL WAS PERFORMED

NHTSA ODI 11312284

ALL THE OIL LEAKED OUT DUE TO A FAULTY OIL COOLER PIPE. THE PART IS FAULTY PLASTIC AND TOYOTA KNOWS THIS IS A DEFECTIVE PART. THEY DID AN "ENHANCED WARRANTY" INSTEAD OF A RECALL. THIS HAPPENED IN MY GARAGE WHEN THE VEHICLE WAS STATIONARY. MESSY AND DANGEROUS.

WHEN ACCELERATING VEHICLE MAKES LOUD HUMMING NOISE. STOPS WHEN YOU TAKE YOUR FOOT OFF THE GAS. I WAS TOLD IT IS THE REAR DIFFERENTIAL. I HAVE READ MANY COMPLAINTS ABOUT THIS FAULTY PART. WHY IS THIS NOT BEING INVESTIGATED? $2000 REPAIR.

THE VAN HAS EXTREME OUTER TIRE WEAR ON THE FRONT OF THE VEHICLE. DRIVER'S SIDE FRONT SEEMS TO BE TO WORST. TIRES ARE BEING ROTATED AT RECOMMENDED INTERVALS (5000-6000MI) AND AN ALIGNMENT CHECK AND ADJUSTMENT IS DONE AT THE SAME TIME. 60,000MI RATED TIRES ARE LASTING 10,000-15,000MI BEFORE REQUIRING REPLACEMENT AND CAUSING VERY POOR TURNING/STEERING, EXCESSIVE STEERING WHEEL VIBRATION AND PULL, AND DRAMATICALLY INCREASED HYDROPLANING IN MILD RAIN CONDITIONS.

RECENTLY STARTED HAVING THIS ISSUE WHILE DRIVING ON THE HIGHWAY. WHEN CHANGING LANES MY DOOR OPEN INDICATOR LIGHT AS WELL AS THE EXCLAMATION INSIDE THE TRIANGLE WILL ILLUMINATE ON MY DASH, A BEEPING SOUND STARTS CHIMING AND ALL THE INTERIOR LIGHTS COME ON. THIS HAPPENS ABOUT 15 TIMES IN A 20 MINUTE PERIOD. ITS VERY AGGRAVATING AND DISTRACTING. IT HAS GOTTEN WORSE AND DOES IT ON SIDE STREETS AND LOWER SPEEDS AS WELL NOW. I HAVE DONE SOME TROUBLE SHOOTING OF MY OWN AND REALIZE THAT IT ONLY HAPPENS WHEN I HAVE A WINDOW CRACKED OR DOWN. IF THE WINDOWS ARE UP IT WILL ALSO HAPPEN WITH SHARP TURNS ENDING WITH ABRUPT BRAKING. I HAVE BEEN PULLED OVER 3 TIMES IN A 4 MONTH PERIOD BECAUSE OF THE LIGHTS GOING ON AND OFF. POLICE SEEM TO THINK I'M SENDING SOME TYPE OF CODE FOR THEM TO HELP ME! IT IS RIDICULOUS. ASIDE FROM THIS LIGHTING/ DOOR ISSUE I AM ALSO HAVING TROUBLE WITH THE SLIDING DOORS CLOSING ON ME WHILE TRYING TO REMOVE MY 10 MONTH OLD SON FROM HIS CARSEAT. I BOUGHT THIS VAN USED AT 99,000 MILES. I NOW HAVE AROUND 120,000. I BELIEVE THIS SHOULD BE AN ISSUE REPAIRED BY A TOYOTA RECALL. I HAVE GOOGLED AND FOUND MULTIPLE COMPLAINTS ABOUT THIS EXACT SAME ISSUE FROM PEOPLE THAT HAVE THE SAME YEAR/MAKE/ MODEL AS MYSELF. UPON BROWSING THROUGH THE RECALLS ON THIS SITE I NOTED THESE ID#S THAT SEEM TO BE THE SAME TYPE OF ISSUE #11025347 #10995738 #10986378 CAMPAIGN # 16V858000 (STRUCTURE) #10928386

THIS IS A MAJOR ISSUE THAT COULD LEAD TO DEATH FOR THE THIRD ROW PASSENGERS. THE LEGS OF THE THIRD ROW DO NOT LOCK INTO THE FLOOR ALL THE TIME. PLEASE SEE PICTURES IT WILL CLARIFY THE ISSUE. IN CASE OF REAR END THE SEATS COULD ROTATE BACK AND THE PASSENGERS COULD HAVE A DIRECT HIT TO THE TOP OF THE HEAD.

ELECTROMAGNETIC COUPLER ON AWD SIENNA, IT SEEMS LIKE A SUPER COMMON PROBLEM THAT COSTS ~$2,500 US TO FIX AND STARTS AROUND THE 100,000 MILE ODOMETER READING.

NHTSA ODI 11267547

BEGAN HEARING A LOUD WHIRRING SOUND FROM REAR OF CAR WHEN CAR IS IN MOTION. GOT LOUDER OVER TIME. OUR REGULAR MECHANIC COULD NOT DIAGNOSE THE NOISE. TOYOTA DEALERSHIP FINALLY DIAGNOSED AS A FAILED ELECTROMAGNETIC REAR COUPLER. SUGGESTED WE NOT USE 'CHEAP TIRES.' WE NEVER HAVE. WE ACTUALLY WENT THROUGH THREE SETS OF THE RECOMMENDED 'RUN FLAT' TIRES IN UNDER 75,000 MILES. AS YOU KNOW, THESE ARE NOT CHEAP TIRES TO REPLACE. COST TO REPLACE COUPLER IS INCREDIBLY HIGH - SHOULD BE COVERED UNDER WARRANTY, AS A GOOGLE SEARCH AND DISCUSSIONS ON TOYOTA CHAT SITES TELL ME THIS IS A COMMON PROBLEM.

NHTSA ODI 11265848

THE UNIT MARKS DOOR OPEN SOMETIMES WHEN DRIVING AND SOMETIMES WHEN THE BRAKES ARE PRESSED DOWN. THE UNIT WAS TAKEN TO AUTHORIZED DEALER BECAUSE THERE WAS A RECALL. THE RECALL STATED THAT THIS ISSUE WAS CAUSED BY THE SLIDING DOOR'S LOCK. THEY VERIFIED THE UNIT AND SAID THE SLIDING DOOR'S LOCK WERE OK, BUT THE ISSUE APPARENTLY WAS ON THE REAR DOOR. THE LOCK ON THE REAR DOOR WAS DEFECTIVE AND THERE WERE NO RECALLS FOR THAT LOCK. THE REPAIR SHOULD BE PAID ON OUR OWN.

MY VAN CUT ON FIRE LAST SATURDAR, SEPTEMBER 1ST 2019. FOR NO APPARENTLY REASON. I DROVE ABOUT 5 MILES FROM MY HOUSE TO THE GROCERY STORE, WHEN I NOTICE THE SMOKE, I FIRST THOUGH WAS THE CAR IN FRONT OF ME. BUT WAS SMOKE COMING FROM MY HOOD. I WAS JUST ABOUT TO STOP AT A STOP SIGH AND I LOOK THE TEMPERATURE GATE AND IT WAS FINE, TURN OF THE CAR AND PEOPLE FROM THE PARKING LOT WAS ALREADY YELLING FOR ME TO GET OUT OF THE CAR.

OIL COOLER HOSE: FROM MY EXPERIENCE, AND FROM WHAT I'VE READ FROM OTHERS, THIS IS A CONSIDERABLE SAFETY ISSUE. A RECALL WOULD BE VERY APPROPRIATE FOR BOTH ROAD SAFETY AND FOR CONSUMER PROTECTION. A SUSPECTED BLOWN COOLER LINE JUST HAPPENED TO ME LAST NIGHT, AND I WAS VERY DISTRACTED WHEN I REALIZED MY 2011 TOYOTA SIENNA (ABOUT 125K MILES) WENT FROM PROVIDING NORMAL RESPONSIVENESS TO GIVING INCOMPREHENSIBLE FEEDBACK WITHIN SECONDS. A "LOW OIL" MESSAGE FLASHED ONCE ON THE CENTER CONSOLE AS I WAS PULLING OUT OF A GAS STATION INTO TRAFFIC. THIS LIGHT DID NOT RETURN. NO OTHER LIGHTS LIT UP AT ANY TIME. IMMEDIATELY, HOWEVER, I NOTICED HESITATION WHEN TRYING TO ACCELERATE. I THOUGHT THAT IT WAS AN ELECTRICAL PROBLEM AT THAT POINT, PERHAPS IT WAS AFFECTING THE FUEL INJECTORS. THEN I NOTICED A CLICKING NOISE COMING FROM THE ENGINE. AT THAT POINT, I PULLED OVER AT THE NEXT SAFEST OPPORTUNITY AND TURNED OFF THE VEHICLE. I POPPED THE HOOD AND NOTICED OIL EVERYWHERE TOWARD THE BOTTOM OF THE ENGINE COMPARTMENT/UNDERSIDE OF THE VEHICLE. THE DIP STICK WAS DRY. THIS ALL HAPPENED WITHIN 0.75 MILES ON A TWO LANE STATE HIGHWAY (ONE LANE IN EACH DIRECTION) WITH A 55 MPH SPEED LIMIT. I CERTAINLY WASN'T DRIVING DEFENSIVELY DURING THIS TIME, AND I HAD VERY MINIMAL AWARENESS OF ANY VEHICLES AROUND ME. THE ACCELERATION ISSUE COULD HAVE BEEN CATASTROPHIC IF I HAD TRIED TO BEAT TRAFFIC THAT WAS FAR ENOUGH AWAY TO PROCEED, YET CLOSE ENOUGH TO THINK TWICE. FORTUNATELY, I'M NOT AN AGGRESSIVE DRIVER, AND I WAITED. THE WHOLE EXPERIENCE HAS BAFFLED ME AS I'VE NEVER EXPERIENCED SUCH A COMPLETE AND SUDDEN FAILURE WHILE DRIVING A VEHICLE. PLEASE CONSIDER THIS REPORT AND REVIEW THE NUMEROUS ONLINE REPORTS FROM DRIVERS WHO ALSO EXPERIENCED A SUDDEN, MASSIVE OIL LEAK WHILE DRIVING THEIR 2007-2011 TOYOTA SIENNAS. TOYOTA IS WELL AWARE OF THIS RECURRING ISSUE. A SAFETY RECALL WOULD SEEM APPROPRIATE.

WHIRRING NOISE FROM THE REAR DIFFERENTIAL WHILE THE VEHICLE IS IN MOTION. THE PITCH OF THE WHIR GETS HIGHER AS THE VEHICLE ACCELERATES. CAUSE IS A FAULTY BEARING IN THE ELECTROMAGNETIC COUPLER ASSEMBLY.

MY DRIVER SIDE SLIDING DOOR WILL NOT OPEN BY EITHER PRESSING THE BUTTONS OR TRYING TO MANUALLY OPEN IT.

FOR YEARS, MY TOYOTA SIENNA HAS HAD A BEEPING NOISE WHEN I WENT OVER A BUMP, OR WHEN IT WAS HOT OUT AND I HAD THE WINDOWS DOWN OR WHEN I PUT ON MY BRAKES. IT GOES OFF AGAIN WHEN I BEGIN TO DRIVE. IT SAID IT WAS THE REAR LIFT GATE WAS AJAR. WHEN I GOOGLE IT, THERE ARE SO MANY PEOPLE WITH THE SAME ISSUE. SOMETHING IS WRONG WITH THE SENSOR, IT'S A BAD MESSAGE THAT COMES THROUGH. TOYOTA SHOULD OFFER TO REPAIR IT. IT IS SO ANNOYING. I'VE HAD MANY MECHANICS LOOK AT IT, AND TOYOTA WANTED TO CHARGE ME $1500 FOR A NEW LIFT GATE SENSOR. WHAT A RIPOFF. ON THE INTERNET MOST JUST DISCONNECT THE WIRE. THIS IS A TOYOTA PROBLEM THAT SHOULD BE RECALLED. IT IS CONSTANT NOW.

WE WERE VISITING NIAGARA FALLS THIS WEEK AND WHEN WE GOT OFF THE EXIT MY WIFE HAD NO BRAKES. SO WE HAD IT TOWED TO A TRIPLE A REPAIR SHOP AND WAS TOLD OUR BRAKE LINE FAILED BECAUSE IT WAS CORRODED AND WAS A CHEAP NON OEM BRAKE LINE. WE HAD TO STAY AN EXTRA NIGHT AT OUR HOTEL. WE BOUGHT IT ALMOST A YEAR AGO WITH 36000 MILES AND NOW HAS 43000 ON IT, I FEEL THAT BRAUNABILITY WHICH DID THE HANDICAP CONVERSION SHOULD HAVE USED A OEM BRAKE LINE WHEN THE REPLACED IT. I HAVE ALS BUT MY WIFE'S NUMBER IS (XXXXX) OR EMAIL ME BACK. WE HAVE A PIECE OF THE DEFECTIVE BRAKE LINE THANKS (XXXXX) PARTS OF THIS DOCUMENT HAVE BEEN REDACTED TO PROTECT PERSONALLY IDENTIFIABLE INFORMATION PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

THIS VEHICLE HAS ALL WHEEL DRIVE AND USES AN ELECTROMECHANICAL COUPLER ON THE REAR DIFFERENTIAL. IT IS VERY SIMILAR CONFIGURATION TO THE TOYOTA RAV4 THAT USES A VISCOUS COUPLER IN THE SAME LOCATION. MY COUPLER HAS FAILED DUE TO THE FRONT BEARING FAILING. THE VEHICLE IS 8 YEARS OLD AND HAS ABOUT 95000 MILES ON IT. TOYOTA HAS ISSUED A TECHNICAL SERVICE BULLETIN AND PROVIDED EXTENDED WARRANTY COVERAGE FOR THE BEARING FAILURE PROBLEM ON THE RAV4. SO FAR, THEY HAVE REFUSED TO PROVIDE SIMILAR COVERAGE FOR REPAIRS ON THE AWD SIENNA, EVEN THOUGH THE FAILURE MODE IS IDENTICAL. WE FIRST NOTICED THE PROBLEM WHEN THE VEHICLE STARTED MAKING LOUD GRINDING NOISE FROM THE REAR AXLE WHILE DRIVING. IT WASN'T CLEAR WHAT THE SOURCE OF NOISE WAS, BUT AFTER FINDING THE SERVICE BULLETIN FOR THE PROBLEM ON THE RAV4, IT BECAME CLEAR THIS SAME BEARING FAILURE WAS HAPPENING ON THE AWD SIENNA'S, SO IT WAS REPAIRED. IT WAS REPAIRED BEFORE IT FAILED CATASTROPHICALLY. IT IS HARD TO KNOW WHAT WOULD HAVE HAPPENED IF THE SOUND WAS IGNORED. WOULD THE DRIVE SHAFT SIEZE UP? ENGINE STALL? TRANSMISSION FAIL? TOYOTA DOES NOT SELL THIS BEARING FOR THE SIENNA, THEY REQUIRE THE ENTIRE COUPLING TO BE REPLACED, WITH A LIST PRICE OVER $1700, PLUS LABOR. THIS DEFECTIVE PART SHOULD BE SUBJECT OF A RECALL AND THE REPAIR PERFORMED ON ALL AWD SIENNA WITH THE DEFECTIVE BEARING CONFIGURATION.
