2006 Toyota Sienna Electrical System Problems

The vehicle stability control system randomly engages and activates the brakes without cause. This can happen on a gentle curve going under the speed limit. It is very scary and I am afraid it is going to cause an accident. Internet research shows many owners with this issue and no information on the cause or a fix

While driving vehicle on dry, non slippery roads with slight to moderate curves, vehicle illuminates Traction Loss light, sounds alarm buzzer, and at times applies brakes and dethrottles engine, even when no loss of traction has occurred. This happens while driving on straight roads with slight unevenness. Had to disconnect wheel speed sensor harness to disable ABS/VSC system. When this happens, the vehicle automatically applies brakes to certain wheels and dethrottles the engine, this can pull the vehicle to one side sharply and can cause an accident.

Vehicle shut off when going over the drain pipe I rolled it into a gas station turned it on and off switched gears and it started to roll back on drive I tried to move the gears and turned off the the vehicle after ward no gear worked.

THIS HAPPENED TO OUR 2006 SIENNA TODAY I WAS ABOUT TO STOP THE CAR WHITE PARKING IT; WE PUT THE PARK THEY SILL RUN; THEY NEVER STOP, SO I TURN OFF THE ENGINE; NOW THEY NO MORE START VERY DAMAGED

WHEN DRIVING THE VEHICLE REGARDLESS OF SPEED OR DRIVING CONDITION THE TRACTION CONTROL SYSTEM RANDOMLY ACTIVATES (IT IS ALWAYS WHEN GOING AROUND A CURVE, BUT ROAD CONDITIONS ARE DRY, SPEED COULD BE 70 OR COULD BE 20, THERE IS NO LOSS OF CONTROL BY ME AS A DRIVER). THIS CAUSES THE CAR TO ABRUPTLY BRAKE. THE COMPUTER SYSTEM SHOWS NO ISSUES WHEN THE DEALER LOOKS AT IT. WHEN I DEACTIVATE THE TRACTION CONTROL SYSTEM USING THE BUTTON THE VAN WILL STILL BEEP LOUDLY INDICATING A LOSS OF TRACTION CONTROL. IT WILL ALSO KICK OFF THE CRUISE CONTROL, BUT DOES NOT ACTIVATE THE AUTOMATIC BRAKING FEATURE. THIS HAS BEEN HAPPENING DAILY FOR 2 MONTHS WITH MULTIPLE VISITS TO REPAIR SHOPS.

A/C SYSTEM HAS HAD PROBLEMS SINCE 2010, THEY REPLACED THE BELTS & TOLD ME IT WAS FINE UNTIL THE WARRANTY EXPIRED.I HAVE HAD RECALLS ON ALL THE DOORS, AIRBAGS &NAV SYSTEM REPLACED THREE TIMES, 2013 A/C WAS REPLACED, 2016 A/C REPLACED AGAIN, & A/C IS BEING REPLACED FOR A 3RD TIME ALONG WITH TWO OTHER RECALLS. TIRE WARNINGS ARE PERSISTENT. I'VE NEVER WORN OUT TIRES OR BRAKES BEFORE, EXCEPT WITH THIS VEHICLE AT A RATE OF EVERY 25,000 MILES. (4TIMES TD)

THE POWER DOORS ON OUR VAN BROKE AFTER HAVING IT REPAIRED. THE DOOR WOULD NOT CLOSE UNTIL I SLAMMED IT SHUT AND THE CABLE SNAPPED. I JUST GOT THE CAR HOME. IT HAPPENED IN OUR DRIVEWAY AS WE JUST GOT HOME. CALLED DEALERSHIP WANTS 2,000 TO FIX. I PAID 800 IN MARCH 2017 FOR SAME DOOR.

ABS, VSC, TRAC OFF, BRAKE LIGHTS ON CONTINUOUSLY, PLUS TIRE PRESSURE LIGHT BLINKING. THIS IS NOT NORMAL AND ALSO ANNOYING. TOYOTA DOESN'T SEEM TO KNOW WHAT THE PROBLEM IS, AND IS ONLY WILLING TO ALLOW ME TO SPEND THOUSANDS OF DOLLARS TO "TRY" TO FIX THIS. TOYOTA NEEDS TO TAKE RESPONSIBILITY! VEHICLE DRIVES NORMALLY. LIGHTS HAVE BEEN ON FOR MONTHS. I WAS DRIVING DOWN THE ROAD, WITH A CAR LOAD OF CHILDREN, LATE AT NIGHT, COMING HOME FROM A FOOTBALL GAME WHEN THE LIGHTS CAME ON. WE WERE DRIVING ACROSS A LONG BRIDGE, ON A 6-LANE ROADWAY, GOING ABOUT 50 MILES AN HOUR. VERY SCARY! I PULLED OVER, BUT SOON REALIZED THE CARE WAS DRIVABLE. I'VE SPENT SO MUCH MONEY, TRYING TO FIGURE OUT WHAT IS GOING ON. I AM SEEING ONLINE THAT THIS IS NOT EXCLUSIVE TO TOYOTAS. MANY VEHICLES EXHIBIT THIS ISSUE. INSTEAD OF HELPING US FIX IT, WE ARE SUPPOSE TO PAY MECHANICS (DEALERS OR INDIVIDUALS), THEN THE PROBLEM COMES BACK. SEEMS NO ONE REALLY KNOWS WHY THIS IS HAPPENING. I'VE BEEN AN EXCLUSIVE TOYOTA OWNER FOR YEARS. IT DISAPPOINTS ME THAT TOYOTA WON'T HELP.

AIRBAG LIGHT GOES ON AND OFF DEALER SAID HE CAN FIX FOR $400. OR MORE. CLAIMS HE WAS ABLE TO WIGGLE IT TO HELP TEMPORARILY. WORKED FOR A SHORT TIME. SEEMS LIKE MANY OWNERS HAVE THIS ISSUE.

LEFT HAND POWER DOOR HAS OPENED AND AT A DIFFERENT TIME CLOSED WITHOUT ANY ACTION BY US.. BOTH TIMES THE VEHICLE WAS NOT MOVING! REASON IS UNKNOWN. *TR

THE REAR PASSENGER AUTOMATIC SLIDING DOOR WILL NOT WORK. IT WILL NOT WORK IN MANUAL OR AUTOMATIC MODE.

SLIDING DOORS OPEN WHILE VEHICLE IS IN MOTION. HATCH BACK DOESN'T OPEN UP BY ELECTRICALLY. HEATING SYSTEM STAYS ON EVEN WHEN TURNED OFF.STEREO TURNS OF WHEN THE HEATER HEATS UP TO LONG.MY SON WAS IN SIDE WERE THE DOOR OPENED UP WHILE WE WERE DRIVING ON A MAIN RD.MY DAUGHTER WAS SITTING ON OPPOSITE SIDE AND SLIDING DOOR POPPED OPEN WHILE ON A MAIN RD.SIDE DOOR STARTED CLOSING WHILE GETTING GROCERIES OUT CAUSING BRUSING TO MY GIRLFRIEND.HATCH DOESN'T WORK. ELECTRICAL PROBLEMS.

THE PASSENGER SIDE POWER AUTO SLIDING DOOR SUDDENLY CAN'T CLOSE ( CLOSED IN HALF WAY THEN STUCK ) , WE MUST USE WIRE TIED WITH THE B BAR TO SECURE THE DOOR. IT'S VERY SHOCK WHY THIS DOOR IS MALFUNCTION WITHOUT NOTICE, MADE THE PASSENGERS IN DANGEROUS SITUATION WHILE DRIVING ON A CITY STREET. WITH A WARNING LIGHT FLASH AND DRIVING SLOWLY TO BACK HOME, THEN HAVE TOYOTA DEALER CHECK THE PROBLEMS. TOYOTA SAID THE CABLE AND MOTOR JAM TOGETHER AND JUST PASS EXTEND WARRANTY ( 9 YEARS OR 120000 MILE WHEN WHICH COMING FIRST ) I HAVE PAY FOR EXPENSIVE REPAIR ($1800.00). I WOULD SAY THE AUTO SLIDING DOOR MUST HAVE SOME METHOD TO MAKE IT CLOSE BY MANUAL TO ENSURE CUSTOMER SAFETY.

SIDE DOOR IS MALFUNCTIONING. HAD TO DRIVE HOME WITH IT OPEN. GRANDDAUGHTER HAD TO MOVE TO REAR BECAUSE I COULDN'T GET IT SHUT AFTER SHE GOT IN. FRIGHTENING EXPERIENCE. SON-IN-LAW HAD TO USE FORCE TO GET IT SHUT. HAVEN'T USED IN 3 MONTHS UNTIL I COULD AFFORD TO HAVE IT LOOKED AT. THERE WAS AN EXTENSION ADDED TO THE WARRANTY BUT SAID I WASN'T ELIGIBLE. $2,125 + TAX TO FIX!!!!

DRIVERS SLIDING DOOR WILL NOT WORK AUTOMATICALLY.

THE DRIVERS SIDE SLIDING DOOR DOES NOT WORK MANUALLY. WHEN I PUSH THE BUTTON I HEAR THE MOTOR TRYING TO OPEN IT, BUT IT DOESN'T OPEN AT ALL.

DRIVER'S SIDE POWER SLIDING DOOR WON'T CLOSE. IT TRIES TO CLOSE WHEN YOU PRESS ANY OF THE BUTTONS OR HANDLE BUT IT GETS STUCK AND REMAINS OPEN.

TL* THE CONTACT OWNS A 2006 TOYOTA SIENNA. WHILE ATTEMPTING TO OPEN THE PASSENGER SIDE REAR SLIDING DOOR AUTOMATICALLY, IT WOULD NOT OPEN. THE DOOR HAD TO BE OPENED MANUALLY. THE VEHICLE WAS NOT DIAGNOSED NOR REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 89,000.
