2005 Toyota Sienna Problems

The dashboard has so many cracks literally everywhere. All the way from the driver side to the passenger side. When the temperature changes hot to cold or cold to hot. There’s nothing but cracking sounds.

The rear hatch on our 2005 Toyota Sienna, after being opened, comes down almost immediately and can hit a person who is reaching into the back cargo area and cause injury. Other people have also reported this same dangerous malfunction online as far back as 2007.

PASSENGER SEAT WARMER WAS ON THE OTHER DAY WHILE I WAS DRIVING AND BEGAN SMOKING AND MELTED THE SEAT IN THE SHAPE OF A DIME. FOR A COUPLE WEEKS IT WAS CAUSING BURNING FEELING IN LEGS FROM BEING TOO HOT. I TURNED OFF SEAT WARMER AND HIT THE SEAT UNTIL THE SMOKING STOPPED.

I WAS COMPLETELY STOPPED IN MY SIENNA AWD AT A TRAFFIC LIGHT AT THE TOP OF A FREEWAY ON-RAMP IN A MAJOR CITY, AND REAR-ENDED BY A VEHICLE BEGINNING TO TRAVEL DOWN THE ON-RAMP AT AN UNKNOWN BUT HIGH RATE OF SPEED AND NOT HEEDING THE TRAFFIC SIGNAL. ON IMPACT, THE REAR CARGO COMPARTMENT OF MY SIENNA CRUSHED INWARD SO FAR THAT IT CAUSED THE THIRD ROW BENCH SEAT TO MOVE FORWARD AND PROPEL THE SEAT PART OF THE BENCH SEAT INTO THE BACKS OF THE SECOND ROW CAPTAIN'S CHAIRS IN FRONT OF IT. THIS WOULD HAVE CRUSHED THE LEGS AND MAYBE WHOLE BODY OF ANYONE SEATED IN THE OUTER TWO SEATS OF THE REAR BENCH SEAT, AND PERHAPS IN THE MIDDLE POSITION AS WELL. I FOUND A PIECE OF PAPER BAG CAUGHT BETWEEN THE BOTTOM SEAT EDGE OF THE BENCH SEAT AND THE BACK OF A CAPTAIN'S CHAIR, AND I COULD NOT PULL THAT PIECE OF PAPER FREE. I HAD TO PULL REALLY HARD TO REMOVE THE LARGE PACK OF TOILET TISSUE, SHOWN IN THE UPLOADED PHOTO, IN ORDER TO DISLODGE IT FROM THE REAR BENCH SEAT AREA. THE TISSUE PACK LIKELY IS NARROWER THAN THE TRUNK OF AN ADULT HUMAN BODY WHICH COULD HAVE BEEN CAUGHT THERE, WITH LEGS ALSO CRUSHED BY THE LOWER PORTION OF THE BENCH SEAT AS IT IMPACTED THE BACK OF THE CAPTAIN'S CHAIR IN FRONT OF IT. I BELIEVE THE CAUSE OF THIS SAFETY PROBLEM IS A POOR DESIGN; INADEQUATE REAR-CRASH PROTECTION FOR THIRD-ROW PASSENGERS, WHO USUALLY ARE CHILDREN. AS A PARENT AND VEHICLE OWNER, I WAS NEVER WARNED ABOUT THE GREAT DANGER MY CHILDREN COULD BE IN IF THEY SEATED ANYWHERE ALONG THE THIRD-ROW BENCH SEAT DURING A REAR-END COLLISION. I'M TRAUMATIZED BY THE THOUGHT OF A CHILD OR ANYONE HAVING BEEN SEATED IN THE THIRD ROW AT THE TIME OF THIS COLLISION, WHICH FORTUNATELY THEY WERE NOT IN THIS INSTANCE.

I was driving on a dry road, going 70mph when my car began flashing the abs indicator and it began breaking and controlling my steering taking me into another lane. The car slowed my vehicle suddenly down to 60 mph and then went off like it never happened. I then had control. There was no reason for the car to do this. There was nothing in the road and luckily no one was to close to me or there would have been an accident. I almost over corrected due to the pulling of the steering and the breaking of the vehicle.

I was driving on dry road at approximately 65mph. There was a very slight curve in the road and the ABS system engaged without warning resulting in the van power immediately decreasing and fishtailing. Fortunately there was no one immediately behind or beside me or it would have resulted in a collision. I am afraid to use the vehicle. Used a code reader and there are no stored codes.

The airbag light is on. The seatbelt on the passenger side gets stuck.

DRIVER AND PASSENGER FRONT SEAT BELTS DO NOT RETRACT PROPERLY. IT GIVES DRIVER AND FRONT PASSENGER A SENSE THAT THE SEATBELTS WORK ONLY TO FIND THE SEATBELT IS LOOSE AT THE WAIST. A KNOWN PROBLEM BY TOYOTA IN THE 2016 "CAMPAIGN" WHEREBY THEY INSTALLED DRIVER AND FRONT PASSENGER SEATBELTS. HERE IT IS 2020 AND THE EXACT SAME ISSUE IS HAPPENING.

When driving on the highway, the van will suddenly brake and the steering will lock up for about 10 seconds. It is truly frightening. It has happened many times, even with the anti-lock button off. I love this vehicle otherwise, but cannot drive it for safety reasons. And I feel bad selling it to anyone else because I don't want anyone to die! The scariest part when it's on a windy 2 lane road. It really becomes non responsive and also the brakes come on when you are going 60+ miles an hour! HELP! I DONT WANT TO DIE

Stability light comes on, decelerates independently, vehicle shakes and steering is somewhat compromised. This has happened rounding curves between 40-50 MPH. Has happened twice on straight road, 8/24 and 8/25/2021, traveling at 70MPH, vehicle decelerated 2-5 miles independently. I put signal on and did smooth lane change to the right to get out of fast lane, and stability light came on, vehicle shook and steering was somewhat compromised. Neither local mechanic or dealership can retrieve any codes with diagnostic equipment. Dealership told me today the light has to stay on for them to retrieve code. This has happened irregularly over the last 6-8 months but always on curves. It has occurred 4 times in 6 days last week, twice on curves, 8/23 & 8/28/2021, and the 2 lane changes above. I am concerned with the increased frequency. There is a great deal of information on the web at https://www.siennachat.com/threads/traction-control-malfunctioning.44474/ so this is not an unknown issue.

I was pulling in my driveway when this incident happened. When exiting my vehicle and opening the driver side door this is what occurred. The driver side sliding door cable snapped and could have potentially hit the driver or me and which could have injured a body part especially the eye or hand. It also made a loud popping noise. There was no warning lights that this would happen and now the door will not open which causes a safety hazard because in case of an emergency this door may need to be opened to escape for safety reasons. Thank you for the investigation of this matter.

215/65 R 16. Four new CONTINENTAL tires fitted early 2021 to Sienna at Discount Tire in Tucson. July 2021 severe vibration and evidence of tire structural issue photographed. All tires showed similar failure mode.. this was on a very hot day. I took the vehicle to Big O tires and had the front two replaced at my expense so the vehicle was drivable. I returned to Discount Tire in Tucson (Speedway) to ask for a recall check after I learned of the 2021 recall on similar Continental tires for sidewall failure. Discount tire reimbursed one tire. I complained to agent Matthew Harby that the other two tires were dangerous because they showed the same sidewall defect on the hot day. He denied my request for replacement if the remaining two Continental tires because there was no open recall on these. I told I him I was worried about a catastrophic failure in normal operation. I then resumed driving. The weather cooled off and until October the two tires behaved normally again.. On 10/30 about 630pm I was dri ong on I10 and experienced catastrophic tire failure in the outside lane speed approx 65mph. I was fortunate to be able to pull over without losing control but the photo shows the extent of this serious failure. I am now at Discount Tire on Ina Road in Tucson requesting replacement of the failed tire and the final remaining CONTINENTAL tire. The photos should show sufficient evidence of sidewall failure matching the failure mode of the recalled tires. THESE ARE DANGEROUS AND NEED NHTSA ACTION WITH A UNIVERSAL RECALL BEFORE A FATAL EVENT OCCURS

TL* TAKATA RECALL. THE CONTACT OWNS A 2005 TOYOTA SIENNA. THE CONTACT RECEIVED NOTIFICATION OF NHTSA CAMPAIGN NUMBERS: 14V273000 (TIRES) AND 13V429000 (ELECTRICAL SYSTEM, AIR BAGS). THE PART TO DO THE REPAIR WAS UNAVAILABLE. THE CONTACT STATED THAT THE MANUFACTURER EXCEEDED A REASONABLE AMOUNT OF TIME FOR THE RECALL REPAIR. THE MANUFACTURER WAS MADE AWARE OF THE ISSUE. THE CONTACT HAD NOT EXPERIENCED A FAILURE. PARTS DISTRIBUTION DISCONNECT.

The dashboard has so many cracks literally everywhere. All the way from the driver side to the passenger side. When the temperature changes hot to cold or cold to hot. There’s nothing but cracking sounds.

Air bag warning light illuminated red on dashboard.

The contact owns a 2005 Toyota Sienna. The contact stated while driving 65 MPH, the oil warning light illuminated. The contact pulled over, opened the hood, and added additional oil. The vehicle was towed to an independent mechanic, who informed him that the engine needed to be replaced. The vehicle was towed to the residence. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not notified. The approximate failure mileage was 142,000.

THE TRACTION CONTROL SYSTEM IS ACTIVATING IMPROPERLY. THE VEHICLE'S ANTI-SLIP INDICATOR WARNING LIGHT ILLUMINATES; AN ALARM SOUNDS; THE ABS SYSTEM ACTIVATES; AND THE VEHICLE SOMETIMES LOSES POWER. THIS HAPPENS ON DRY ROADS, MOST COMMONLY EITHER GOING DOWNHILL OR ELSE ON A CURVE, EVEN A MILD ONE. THIS HAPPENS ABOVE 20 MPH. WHEN IT HAPPENS, THE COMBINATION OF ALERTS AND SENSATIONS ARE VERY STARTLING TO THE DRIVER, CREATING A DANGEROUS SITUATION. IT HAS OCCURRED WHILE TRYING TO ACCELERATE TO MERGE ONTO A HIGHWAY. THIS WAS EXCEPTIONALLY DANGEROUS AS THE VEHICLE BEGAN LOSING POWER AND VEHICLES BEHIND US ALMOST HIT US FROM BEHIND AS WE WERE SLOWING INSTEAD OF INCREASING SPEED. FROM MY INTERNET SEARCHES (INCLUDING NHTSA COMPLAINTS), THIS APPEARS TO BE A RECURRING ISSUE WITH THIS MAKE/MODEL/YEAR RANGE. THIS HAS BEEN HAPPENING FOR THE PAST 3 MONTHS. OUR VEHICLE HAS APPROXIMATELY 135,000 MILES ON THE ODOMETER.

FRONT TIRES - EXCESSIVE TIRE WEAR PROBLEMS

shifter broke at 55 mph wouldn't stay in 5 gear, was easily moved to R, N, and flopped around! won't stay in 4 now when used either, or PARK unless held when turning car off. NO warning, shifted down for a hill, speed limit change, and corner in neighborhood as usual, no lights on in car. just happened but upon research, have found many others with this problem online, same veh and same kind of miles.Toyota knows but won't recall their broken plastic piece and no notification to consumer

The stickiness of the dashboard causes unwanted glare and reflections on the windshield, especially when driving in bright sunlight. This glare and reflection make it extremely challenging to maintain a clear and unobstructed view of the road ahead, leading to hazy and blurry vision. As you can imagine, this compromised visibility poses a significant safety risk for both my family and other road users. The dashboard was recalled by Toyota however the part was not available at first for many months and by the time I inquired again, the recall had already expired, leaving us without a viable solution.

The contact owns a 2005 Toyota Sienna. The contact stated while driving 70 MPH, the sunroof glass detached from the vehicle and struck the windshield of the vehicle driving behind him. The contact stated that he continued to drive and exited the highway and parked to inspect the vehicle.

Upon investigation, the contact associated the failure with NHTSA Campaign Number: 11V042000 (Visibility) however, the VIN was not included. The vehicle is being repaired. The contact called manufacturer Webasto and left them a voicemail but had not yet spoken to a representative. The failure mileage was approximately 186,000.

I DIDN'T KNOW THE CAR WAS GOING TO BE RECALLED.

TL*THE CONTACT OWNS A 2005 TOYOTA SIENNA. THE CONTACT TURNED THE IGNITION OFF, AND THE GEAR SELECTOR WAS SHIFTED INTO THE PARK POSITION. SUDDENLY, THE VEHICLE LUNGED FORWARD WITHOUT WARNING. WHEN PRESSURE WAS APPLIED TO THE BRAKE PEDAL THERE WAS NO POWER RESPONSE. WHEN THE EMERGENCY BRAKE WAS ENGAGED, THE VEHICLE CAME TO A STOP. THE CONTACT INSPECTED THE VEHICLE AND DETECTED THAT THE GEAR SHIFT CABLE HAD DISENGAGED, POSSIBLY WHEN ENCOUNTERING A BUMP IN THE ROAD. THE MANUFACTURER AND AN AUTHORIZED DEALER WERE NOTIFIED OF THE FAILURE. IN ADDITION, THE SPEEDOMETER WOULD DISPLAY AN INACCURATE READING AT VARIOUS SPEEDS. THE VEHICLE HAD NOT BEEN REPAIRED WHEN THE COMPLAINT WAS FILED. THE FAILURE MILEAGE WAS 114,000. THE VIN WAS UNAVAILABLE.

THE ACCELERATOR STUCK ON THIS VAN AS I WAS PASSING ANOTHER VEHICLE ON A RURAL, TWO LANE ROAD. AS SOON AS I DEPRESSED THE ACCELERATOR TO PASS, I KNEW SOMETHING WAS WRONG. THE GAS PEDAL STAYED DOWN EVEN AFTER I REMOVED MY FOOT AND THE VAN CONTINUED TO ACCELERATE EVEN FASTER EVEN THOUGH I WAS NOW HITTING THE BRAKES HARD! WITH CURVES IN THE ROAD APPROACHING IN ABOUT A MILE, I HAD TO DO SOMETHING FAST! I WAS STANDING ON THE BRAKES WITH BOTH FEET NOW AND THE VAN CONTINUED TO SPEED UP. I WAS ABLE TO SHIFT IT INTO NEUTRAL, ALL THE WHILE CONTINUING TO STAND ON THE BRAKES. THE ENGINE REVVED EVEN FASTER BUT I WAS ABLE TO GET THE VAN TURNED OFF THE ROAD INTO A FARM FIELD ACCESS DRIVE. THE VAN STILL WASN'T STOPPING BUT AT LEAST I WAS OFF THE ROAD AND NOT GOING TO HIT ANOTHER VEHICLE. AS THE VAN CONTINUED TO MOVE, I THOUGHT ABOUT BAILING OUT BUT THANKFULLY, I DIDN'T. THE VAN WAS STILL GOING FAST ENOUGH IT COULD'VE RUN OVER ME AND I HAD NO IDEA WHERE IT WOULD END UP IF I GOT OUT! BY THE GRACE OF GOD, THE VAN FINALLY STOPPED AFTER I STARTED TURNING THE WHEEL HARD TO THE LEFT. I SHIFTED IT INTO PARK AND SHUT IT OFF WHILE I SAT THERE SHAKING AND TRYING TO DECIDE WHO TO CALL FIRST. THIS SITUATION COULD HAVE TURNED OUT EXTREMELY BAD HAD THE CIRCUMSTANCES BEEN DIFFERENT. THANK GOD THERE WAS NO ONE IN FRONT OF ME WHILE THIS WAS GOING ON, I WASN'T IN A CONGESTED AREA OF HOUSES OR OTHER VEHICLES OR ON A BUSY HIGHWAY. I'M SO GLAD ONE OF OUR BOYS WASN'T DRIVING THIS WHEN IT HAPPENED! THIS WAS THE SCARIEST THING THAT'S EVER HAPPENED TO ME WHILE DRIVING OVER 30 YEARS! THE VAN WAS TOWED TO THE DEALERSHIP WHERE WE PURCHASED IT AND HAVE HAD IT SERVICED FAITHFULLY. I'M WAITING TO HEAR BACK FROM THEM WHEN THEY WILL BE ABLE TO LOOK AT IT. *TR

DRIVER SIDE PASSENGER DOOR WILL NOT OPEN PAST ABOUT 4 INCHES DUE TO LOCKING MECHANISM AT BOTTOM THAT ENGAGES WHEN FUEL DOOR IS OPEN STUCK IN THE UP POSITION. FUEL DOOR IS CLOSED BUT THE LOCKING MECHANISM THAT PREVENTS THE DOOR FROM OPENING WHEN THE FUEL DOOR IS OPEN REMAINS UP. *TR

TL* THE CONTACT OWNS A 2005 TOYOTA SIENNA. THE CONTACT STATED THAT THE HEADLIGHT INTERIOR PLASTIC COVERS FAILED. THE HEADLIGHT COVERS EXHIBITED A HEAVY, WHITE, FOGGY DISCOLORATION. THE DEALER STATED THAT THE HEADLIGHT INTERIOR COVERS NEEDED TO BE REPLACED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE HEADLIGHT INTERIOR COVERS WERE NOT REPLACED. THE APPROXIMATE FAILURE MILEAGE WAS 50,000.

THE RIGHT SIDE (PASSENGER) HEADLIGHT WENT OUT. REPLACEMENT OF THE LIGHT BULB (WHICH WAS A WHOPPING 190.00) DID NOT SOLVE THE PROBLEM. WAS TOLD THAT IT IS A SPECIAL TYPE OF HID LIGHT WHICH HAS A HEADLAMP CONTROL MODULE AKA BALLAST AKA COMPUTER THAT COULD BE BAD. DEALER QUOTED $600 TO FIX A HEADLIGHT. MY OTHER REPAIR SHOP QUOTED $450. REALLY TOYOTA? $450-600 TO FIX A HEADLIGHT???? RIDICULOUS. NO ONE SHOULD HAVE TO PAY THIS MUCH TO FIX A HEADLIGHT. WHO ENGINEERED THIS? BEYOND FRUSTRATED.

When driving the speed limit, going downhill, uphill, straight, around a curve, in the rain or dry weather, the vsc and slip/trac lights up, the abs system is activated / brakes engage. I loose complete control of the van. I can no longer steer or break. The breaks engage, but it causes the car to veer to the right. I have taken the car to the mechanic 5 times now and no codes show, even after he is able to the vehicle to repeat this behavior. It seems to happen a lot on off/on ramps. It happens mostly on highways, but it has happened on two lane roads. The vehicle is completely dangerous to drive. It has almost caused several accidents. I have replaced the Yaw sensors and had several alignments and this still happens. After a lot of research, we have found that this is actually really common in Toyota Sienna. People are saying that the bushings in the rack in pinion wear out and the entire rack and pinion system needs to be replaced. Some people have replaced the rack and pinion and claim that there is still a problem. But the majority say after the rack and pinion is replaced there is not further problems.
