2009 Toyota Sienna Electrical Problems

Your rear passenger door is opening on its own while driving, possibly because the door latch isn't engaging properly with the car frame. During a left turn, the door slid open unexpectedly. Additionally, the cables on your driver-side rear sliding doors came loose about a year ago, likely due to rust or corrosion. The door latch mechanism may need adjustment or replacement, and the sliding door cables may need to be reattached or replaced.

You discovered that after selling your 2009 Toyota Sienna privately for 253,000 miles, the new owner rolled back the odometer to show 126,000 miles when reselling the vehicle. This odometer tampering was discovered when you noticed the vehicle reposted for sale on Craigslist with the false mileage displayed. Addressing odometer fraud may require digital odometer recalibration or replacement of the instrument cluster.

Your vehicle is draining its battery completely overnight due to an unknown electrical problem, leaving you unable to start the car even in emergencies. Your mechanic has confirmed there's an electrical draw but hasn't been able to locate the source of the short circuit. Finding and repairing the electrical short will likely involve systematic testing of various electrical components and circuits.

Your rear passenger sliding door cable and motor assembly failed, leaving the door completely stuck and unable to open or close. As your wife was trying to close the door, the cable snapped under tension and flew toward her, creating a safety hazard. The dealer confirmed the problem and Toyota acknowledged it as a defect, but has refused to repair it or issue a recall.

Your 2009 Sienna's driver-side power sliding door cable snapped, and you were initially told by Toyota that your model year wasn't covered under their warranty extension program—even though similar issues on nearby model years were covered. When you repaired it yourself, you found missing screws around the pulley system and damage where the broken cable cracked the door housing and tore the sound insulation. The repair involves replacing the power sliding door cable assembly and associated hardware.

SLIDING SIDE DOORS OPEN ON OWN. BUTTON FAILS TO ENGAGE PREVENTING DOOR FROM CLOSING. HAPPENED MULTIPLE TIMES AFTER PULLING INTO A PARKING SPOT AND PUTTING THE CAR IN PARK. BOTH TIMES IT HAS BEEN THE PASSENGER SIDE SLIDING DOOR.

I WAS DRIVING MY SIENNA ON A 2 LANE TOWN ROAD AND WITHOUT WARNING SMELLED SMOKE. AS I WAS PULLING OVER CARS IN THE ONCOMING LANE WERE HONKING AT ME AS THEY SAW THE FIRE UNDERNEATH WHERE THE ENGINE IS. WHEN I PULLED OVER SMOKE ENTERED INTO THE CAR. I STEPPED OUT, HEARD A POP, AND NOW THE ENTIRE FRONT OF THE CAR WAS FULL ON FIRE. THE FIRE DEPARTMENT ARRIVED ON SCENE QUICKLY AND EXTINGUISHED THE FIRE. I FILED AN INCIDENT REPORT WITH TOYOTA. I RECEIVED A CALL FROM A MAN SAYING HE WAS HIRED BY TOYOTA TO INVESTIGATE THE FIRE AND REPORT BACK TO THEM. TO DATE, I HAVE RECEIVED ZERO COMMUNICATION FROM ANYONE AT TOYOTA REGARDING THIS SERIOUS MATTER.

IN LATE 2016, THE DRIVER SIDE REAR SLIDING DOOR POWERED CABLE/MOTOR ASSEMBLY BROKE. IN APRIL 2017, THE PASSENGER SIDE REAR SLIDING DOOR POWERED CABLE/MOTOR ASSEMBLY BROKE. TOYOTA REFUSES TO COVER THE COSTS OF THE REPAIR. THE DOOR IN 2017 BROKE JAMMED IN THE OPEN POSITION, REQUIRING ASSISTANCE TO CLOSE IT TO GET HOME WITH CHILDREN IN THE CAR. ONCE CLOSED, THE DOOR WOULD NOT OPEN, CAUSING A SAFETY CONCERN. THE VEHICLE WAS IN A PARKING LOT WHEN THIS OCCURRED.

PASSENGER SIDE SLIDING DOOR STOPPED WORKING AND THE BEEPER IS ON AT ALL TIMES. LOCAL DEALER STATED THAT THE COST OF REPAIR WOULD BE UP TO $3300.00. IS THERE A MORE COST EFFECTIVE OPTION FOR ME?

POWER SLIDING DOOR CABLE FAILURE THAT PULLS THE DOOR OPEN. NINE OPENED ABOUT 6 INCHES THEY STOPPED AS IF IT HIT SOMETHING. HAD TO BREAK THE CABLE TO GET DOOR OPEN

BOTH SLIDING DOOR CABLES HAVE BROKEN UNDER NORMAL USE AND WERE PREVIOUSLY REPLACED BY TOYOTA. THE GENUINE TOYOTA REPLACEMENT CABLE ON THE DRIVER SIDE HAS BROKEN A SECOND TIME, INCLUDING DAMAGING THE MOTOR ASSEMBLY. THE DOOR DOES NOT OPEN OR CLOSE PROPERLY AND TEMPORARILY TRAPPED MY DAUGHTER INSIDE WHO DID NOT KNOW HOW TO OPEN THE DOOR BESIDES USING THE DOOR OPEN BUTTONS AND HANDLE. ONE DAUGHTER WAS STANDING OUTSIDE THE VEHICLE WHEN THE CABLE SNAPPED AND IT NEARLY CUT HER NECK (IT CAME ABOUT 2 INCHES FROM HER NECK WHEN IT SNAPPED OUT OF THE TRACK). THIS IS A KNOWN ISSUE AT TOYOTA WHERE THE PLASTIC COATING BREAKS ALLOWING THE CABLE TO RUST. HAVING INOPERATIVE OR IMPROPERLY OPERATING DOORS CREATES A SIGNIFICANT SAFETY RISK, INCLUDING VEHICLE ENTRAPMENT AND INABILITY TO ENTER/EGRESS FROM THE NON-TRAFFIC SIDE OF THE ROADWAY. *TR

2009 TOYOTA SIENNA, DRIVERS SIDE REAR PASSENGER DOOR CABLE BROKE AND INITIALLY LEFT THE DOOR IN THE OPEN POSITION IN A MALL PARKING LOT. ONCE CLOSED MANUALLY TO TRAVEL HOME, THE DOOR WAS LEFT JAMMED IN THE CLOSED POSITION UNTIL WE ARRIVED HOME. I HAD TO CUT THE CABLE ASSEMBLY OUT TO SIMPLY REMOVE THE SAFETY HAZARD FOR MY 3 YOUNG DAUGHTERS. ATTEMPTED TO HAVE THE DOOR REPAIRED AT A LOCAL SHOP WHICH WAS UNABLE AND CHECKED WITH TOYOTA THEMSELVES. TOYOTA'S RESPONSE WAS THAT THE NEW CABLE/MOTOR ASSEMBLY WAS UPGRADED AND ONLY AVAILABLE THROUGH TOYOTA FOR $1300(+LABOR), I CONTACTED TOYOTA CORPORATE WHO HELPED MINIMALLY WITH THE BILL TO GET IT FIXED. STILL COSTS ME OVER $1100 TO GET A FUNCTIONING DOOR AND REMOVE A HUGE SAFETY CONCERN ON A VEHICLE WHERE I PAID INITIALLY FOR THE FEATURE.

THE RUBBER FROM BACK DOOR MELTED SINCE I LIVE IN TROPICAL ISLAND AND THERE IS A LOT OF HEAT. THE PLASTIC BASE FOR THE ANTENA BROKE, I GUES THE HEAT CRACKED THE PLASTIC BASE, AND THE CELL CHARGER DOESN'T WORK, THOUGH I HAVE HARDLY USED IT. I SEEMS LIKE IT GETS OUT OF POSITION EASILY. OVERALL, THE PLASTIC FEATURES ARE GIVING ME A HARD TIME. I LOVE MY SIENNA AND IT'S IN VERY GOOD CONDITION, BUT THESE PROBLEMS DON'T HAVE TO DO WITH USE.

THE CABLE IN BOTH REAR SLIDING DOORS SNAPPED IN TWO. THE DOORS ARE LATCHED CLOSED AND WILL NOT OPEN ELECTRONICALLY OR MANUALLY, REQUIRING ANY REAR PASSENGERS TO ENTER AND EXIT THROUGH THE FRONT PASSENGER DOOR AND CLIMB IN TO THE BACK SEATS. AGAIN, THE DOORS ARE CLOSED FAST AND WON'T OPEN USING EITHER MANUAL OR POWER MODES. I AM UNABLE TO TRANSPORT MY CHILDREN DUE TO SAFETY CONCERNS THAT IF WE WERE INVOLVED IN AN ACCIDENT I COULD NOT REMOVE THEM FROM THE CAR. WHILE THERE ARE SEVERAL INSTANCES OF THIS PROBLEM ON INTERNET CHAT FORUMS, TOYOTA IS NOT ADDRESSING THE PROBLEM. THE COST TO REPAIR ONE DOOR IS $1,700, MAKING THE REPAIR TOTAL FOR BOTH DOORS AN INCREDIBLE $3,400. I HAVE CONTACTED TOYOTA AND THERE IS NO RECALL OR HELP FOR THE REPAIR. THIS AMOUNT IS NEARLY THE MARKET WORTH OF THE TOTAL VEHICLE.

DRIVER'S SIDE POWER BACK DOOR CABLE SNAPPED WHILE THE CAR WAS STATIONARY IN THE DRIVEWAY. PRESSED THE BUTTON TO OPEN DOOR AND HEARD THE SNAP. LATCH WORKS BUT DOOR WON'T OPEN UNLESS YOU OPEN IT MANUALLY. 76,000 MI. TOYOTA SIENNA '09. THERE IS CSP THAT COVERS THIS CABLE FOR 2004-2007 MODELS THAT WAS MADE IN 2012. THE CSP NEEDS TO BE UPDATED TO INCLUDE THE MORE RECENT MODEL VEHICLES AS THE PROBLEM STILL EXISTS. DEALERSHIPS ARE CHARGING $2400 TO REPLACE IT. THE AUTO DOORS WERE THE MAIN REASON I BOUGHT THIS VEHICLE. WITH AT LEAST ANOTHER YRS ON THIS VEHICLE LEFT, I AM EXTREMELY UPSET THAT THIS ISN'T COVERED. THIS IS NOT A USER ERROR.

I HAVE A 2009 SIENNA WITH LESS THAN 90,000 MILES ON IT. THE SLIDING DOOR CABLE SUDDENLY SNAPPED AND I WAS STUCK WITH THE DOOR NOT FUNCTIONING AT ALL. IT WAS STUCK HALF OPEN. I HAD TO USE CONSIDERABLE FORCE TO SHUT IT. THE CABLE EXHIBITS CORROSION UPON VISUAL INSPECTION. BASED ON THE AMOUNT OF COMPLAINTS THIS SEEMS TO BE A CONSISTENT ISSUE WITH SIENNAS. TOYOTA DEALERSHIP IS ASKING FOR ABOUT $1800 TO FIX IT.

THE CABLES THAT ENABLE THE SIDE DOORS TO OPEN BOTH SNAPPED WITHIN 2 WEEKS OF EACH OTHER. BOTH OCCURRED WHILE TRYING TO OPEN THE DOORS WITH THE POWER BUTTON. THE DOORS ARE UNABLE TO BE OPENED WITHOUT BEING REPAIRED.

DROVE OF F ONE DAY AND HEARD BEEP BEEP WITH THE HAZARD LIGHT ON. PULLED OVER AND COULD NOT FIGURE OUT WHAT WAS THE PROBLEM. THE DOOR WAS OPEN. WHAT? TRIED TO CLOSE IT THE BUTTON, THEN HAD TO SLAM DOOR SHUT.THE LEFT SLIDING DOORS HAS STOPPED WORKING. THE CORD GOT FRAYED AND DRY AND JUST BROKE OFF ONE DAY. I HAD TO FORCE CLOSE THE DOOR AND MY KIDS NOW HAVE TO USE ONY ONE DOOR. NOW I SEE THE SECOND DOOR IS ACTING THE SAME. VERY DISAPPOINTED AND SAD AND AFRAID. A BIG SAFETY ISSUE. IS THERE A RECALL.

POWER SLIDING DOOR CABLE FAILED/FAULTY. RISK OF INJURY AND SAFETY. TOYOTA UNWILLING TO REPAIR UNDER WARRANTY. SLIDING DOOR INOPERABLE - CAN'T EXIT VEHICLE ON SIDE WHERE DOOR CABLE BROKE. THIS IS A WIDELY KNOWN AND WIDELY EXPERIENCED SAFETY DEFECT ACROSS 6 YEARS OF TOYOTA SIENNA THAT SHOULD BE THE SUBJECT OF A FEDERAL RECALL. *JS

LEFT AUTOMATIC SLIDING DOOR CABLE SNAPPED AFTER THE RIGHT DOOR CABLE SNAPPED TWO MONTHS PRIOR RIGHT AFTER WARRANTY EXPIRED. TOYOTA FIXED THE FIRST PROBLEM BUT WILL NOT FIX THE OTHER DOOR AND WANTS $2000 TO FIX IT. THE CAR IS ONLY 5 YEARS OLD AND TOYOTA KNOWS THIS IS AN ISSUE BUT WILL NOT HELP. THIS IS NOT RIGHT. MY CHILD WAS SEAT BELTED IN WHEN THE CABLE SNAPPED AND IT WHIPPED AROUND AND ALMOST HIT HER IN THE HEAD. THIS IS VERY SERIOUS AND TOYOTA NEEDS TO MAKE IT RIGHT. *JS

THE SIDE AUTOMATIC DOOR CABLE SNAPPED. IF MY CHILD WAS IN HIS SEAT HE WOULD HAVE BEEN INJURED BAD. THE TENSION ON THIS WAS TREMENDOUS. ALL MY WIFE DID WAS OPEN THE DOOR. WE HAVE A 2009 SIENNA AWD AND HAVE MAINTAINED IT PER TOYOTA INSTRUCTIONS. TOYOTA WANTS $1100 PLUS $300 DO DIAGNOSE THE PROBLEM. THIS IS JUST WRONG. PLEASE HELP. THE CABLE WAS HANGING WHERE MY SON WOULD BE SITTING. *TR

PASSENGER POWER SLIDING DOOR CABLE BROKE. *TR

POWER DOORS NOT WORKING WILL NOT OPEN OR CLOSE ON AUTO ALL THE TIME OR ON MANUAL NOW DRIVERS SIDE CABLES HAVE BROKE. *TR
