AC light blinking AC condenser replacement twice in 2 years

The electric sliding door cable broke due to unknown reason and the door partially opened and will not open even manually now.

"The vehicle suffered a critical failure of the shift interlock safety system. After parking in a driveway, the ignition key was able to be fully turned to the 'off' position and removed from the ignition cylinder, even though the transmission was not successfully secured in 'Park.' After the key was removed and I and went into the house the van rolled away. It traveled downhill, crashed through a fence, and collided with a residential structure, causing significant property damage to the house and vehicle. This failure could potentially cause serious injury or death and this was the first time that it had occurred and is exhibiting the same failure as described. Immediately following the collision, video evidence was recorded showing the key in hand while the dashboard indicators and shifter remained out of the 'Park' position. This indicates the safety mechanism designed to prevent key removal unless the vehicle is in 'Park' failed to operate, creating a life-safety rollaway hazard."

Driver side back passenger door would not open or close properly. The door opened while driving on the road. It did t want to shut. It was difficult to get it shut once I stopped.

I was at a red traffic light. I pressed the brake pedal. The vehicle wouldn't stop. The engine was revving. This happened twice within a month.

Two Front Tires 235/55R18 100V wore down to completely unsafe condiotion and had to be replaced. Tires were on vehicle less than 8 months and had less than 10K miles on them.

Water leaks to the driver and passenger floor when it rains, it seems a leak is coming from the windshield area, touching the car hood

Pressed the button to open the rear passenger sliding door and it would open. When opened manually it would open only about 12 inches. Then when we were driving on the highway the door opened on its own. The door had to be manually closed and now it will not open. This is now a safety concern that in the event of a crash passengers may not be able to exit the vehicle or the door could open again while driving.

Sienna had recall on airbags that were fixed. I have a warning dashboard light that says there is an issue with my airbags and the seat belt light is on. According to the dealer there is an issue with the computer board. They purposed to fix the issue at 800.00 dollars. This is a safety issue due to the expensive cost to fix this. The dealer already had to replace the airbags and now there is something wrong with the computer board and currently I do not have airbags.

POWER SLIDING REAR DOORS OPENED WHILE DRIVING, PROBLEMS WITH SLIDING DOORS LOCKING MECHANSIM ON BOTH SIDES, FRONT AND THE REAR LOCKS

The side door opens well driving and there are kids in the van. Has happen 3 times.

Sliding door will lock and not open when prompted, manually or electrically, sometimes it will pop open

The 2GR-FE engine on my Sienna has experienced a front timing cover leak. It's slowly leaking oil out of my vehicle and I'm afraid it will get worst over time. My vehicle has less than 100K miles and if the leak persists, I down want my vehicle breaking down and leaving me stranded.

I had sever car accident while I am 7 months pregnant including my 5 years old sons . During the accident my airbag was not deployed which lead me hematoma in my uterus. That car is totally losses and the accident was severe .Thank God we put the sit belt and even if the frontdash board hit me bad . I will attach all the details of the accident and the police report. We tried to submit our complaint to Toyota and they refused to help .As if the air bug should not supposed to deploy with that kind of severe accident they say they don’t use this information .

2013 TOYOTA SIENNA. CONSUMER WRITES IN REGARD TO ELECTRONIC LATCH FAILURE.

Anyone: In 2013 I bought a new Toyota Sienna from Fiore Toyota in Hollidaysburg, PA. It was advertised with a lifetime engine and powertrain warranty. I thought that I had made a wise purchased. Fast forward to 2022. In early June I noticed a loud humming from the rear differential area and since I had a family vacation planned with my son’s family I decided to take it in for diagnosis to my local dealer, Colonial Toyota of Indiana, PA. They said that it was the electromagnetic control unit but could not get me in for over a week and that it was not advisable to drive long distance. This resulted in my rented a replacement vehicle – an unanticipated expense. When I returned I took the vehicle into Colonial on July 7th and asked if the part would be covered under the lifetime warranty. They said they would check it out. There were several slow responses between the garage and the warranty company. Requests for additional service records, VIN numbers and what not. Meanwhile I am without a vehicle. Colonial had said that the part should be covered under the contract. Also Colonial’s lifetime warranty was a different company than Fiore’s insurer. Who knew? I had assumed that it was all a Toyota thing. Meanwhile after 8 days of no vehicle and another trip to Colorado approaching, (Granddaughter living alone while her husband is deployed in Poland.), I pulled the trigger and said fix the vehicle as I needed it. My thoughts were that it was a Toyota vehicle, serviced by Toyota “cert

Starting about two years ago, the traction/ABS lights come on between 20-35 mph on a gradual curve or randomly while driving. The brakes come on, like an ABS event, even though the brakes are not applied. The car will jerk to the right or left and chatters/vibrates. The mechanic said the brakes, tire wear and pressure, and suspension are all in very good condition and there are not traction control or ABS codes. This does not appear to be normal wear and is dangerous. We can only drive it on short trips for fear of getting in an accident. I decided to look online and found that hundreds of Toyota owners are experiencing the same symptoms. (https://www.cargurus.com/Cars/Discussion-c9152_ds656326). Can anything be done so that Toyota will come up with a solution? Thank you.

I was gonna make a U-turn at the end of the road and then the steering made a cracking noise. The steering shaft has been replaced 3 TIMES and it still happens. So much for Toyota Reliability.....................

I was driving down the street and then my car lurched forward, the engine revving up. It is a 2013 Sienna XLE V6 & it had 113,000 miles on it. I had to STOMP on the brake to get it to stop.

After a big snow storm I cleaned the car off and warmed it up, then tried to open the passenger side power door from the inside side with the button. The passanger side would not open (driver's side did) so I tried to open it manually from the outside and then the inside. It would not open at all. Then as I was driving, the car started beeping and the 'door open' icon lit up on the dashboard. I stopped the car and again tried to manually push the door shut as it appeared to be slightly ajar at this point. It seemed to close but the light and beep stayed on for my 10 minute drive home. When I got home I inspected more and noticed a wire for the power door had snapped at some point, I assume from the cold because it was operable the evening before. At this point I cannot open that door manually either, it is completely stuck shut, which I feel is a safety issue as my kids only have one point of egress. I did some research and this seems to match the description of one of the recalls but I was told my vehicle was not included based on the VIN #.

A few days ago the seat belt sensor would continue to beep and blink even after the seat belt was fastened. Then, on Friday, December 24th, 2021, a piece popped out of the seat belt latching mechanism on the driver's seat. Now it is difficult to get the seat belt to latch, and I am unsure that the latch would hold if the vehicle was in an accident that could cause serious injury to the driver. This is available to be inspected upon request. I haven't taken this to be looked at yet, but would like to know if this is something that I would have to pay for or if the manufacturer would cover the cost of this repair.

SRS Airbag check issue. Last few days, my car has been showing following symptoms 1) Day 1: SRS airbag check warning is flashing on the display. The passenger airbag is always OFF regardless of the passenger being seated or not. 2) Day 2: SRS airbag check warning goes away, but passenger seat airbag is always ON regardless of anyone sitting or not. Also the seat belt chime is sounded for the passenger seat. 3) Day 5: SRS airbag check warning comes back and passenger airbag is OFF. (same as Day 1). The auto mechanic says there is a code about Occupant classification system that is malfunctioning. Dealer wants to charge me a lot of money just to get it inspected and diagnosed. The car has not been in any collision. This seems like totally Toyota's design and part reliability issue. In no condition the driver or passenger safety should be compromised in such manner. Yet Toyota dealership is not standing behind their mfg commitment to safe driving experience.

This is to advise you of a safety issue with our 2013 Toyota Sienna XLE Minivan having a V6 (3.5L) engine. Our vehicle currently has 118,169 miles on it and has been well maintained. This vehicle was purchased new and is operated primarily in Florida where we live. Over the last 6 - 10 months on three occasions our Sienna Minivan suddenly lurched forward as the engine revved up. On all three occasions, I had to take quick action and with significant force press the brake pedal as well as place the minivan in neutral and then into park in order to stop our minivan from surging forward and hitting the car in front of me. On all three occasions, my right foot was on the brake pedal when this occurred and on two of the three occasions, our minivan was slowly accelerating from either a stopped position or a very low speed (5 mph or less). On one of the occasions I was approaching an intersection with a stop sign and our minivan was decelerating to a stop when the engine revved up and the minivan surged forward. This occurred as our minivan was going approximately 5 - 10 mph. There were no warning lamps, messages, or other symptoms prior to any of these incidents. I have reported this condition to our local Toyota Dealer but they said they could not duplicate the issue during their test drive. This is a serious safety condition and one that could result in a serious accident with injuries particularly if the driver is not quick to react to this unexpected condition.

Despite a full sized adult sitting in the passenger seat, the AIRBAG OFF light remains on at all times.

Drivers Seat belt latch had a spring pop out. It continued to work for a short time although less functional and then it would no longer latch.

My 2013 Toyota Sienna had two recalls, which are Power Sliding Do0r and Front Passenger Airbag inflator. My vehicle has been inspected and fixed. However, my recall status of the vechicle has not been updated, and continuously receive notice from Dealer and NHTSA.

The passenger side automatic sliding door came off track and shattered the rear window. Glass flew all over our daughter in her car seat. The van had recall power sliding door service done, but it still failed. Roller bearings were badly worn.

Grinding noise began from the rear of the vehicle increasing as acceleration increased. Took to the shop and found at the Rear Differential failed at 75,000 requiring replacement for thousands of dollars. The same year RAV4 has been recalled for this already - the Sienna should have a recall also. The dealership had the part on the shelf, surprise surprise.

I have been notified by my Toyota dealership that the rear viscous coupler on my Sienna has failed and that the RAV4s have been recalled for this same part as a safety issue ( years ago). This part is a known manufacturing defect. Forums are wallpapered with complaints about this for years, I've already lodged a complaint with Toyota but they are doing nothing. Customers should not be on the hook for a $2500 repair that is a known manufacturing defect. The coupler recall should be extended to the Siennas!

The passenger side door wont open when commanded. Couple years back i took it in for repairs. But the problem still persists.

DURING MY 60K SERVICE (57K MILES RUN) ON APR 20, THE LOCAL TOYOTA DEALERSHIP (PIERCEY TOYOTA) IDENTIFIED A MAJOR SERVICE RELATED TO SUSPENSION WHICH IS EXPECT TO COST AROUND $3000. MY VEHICLE USAGE IS MINIMAL WHICH IS QUITE EVIDENT FROM BARELY 57000 MILES RUN DURING LAST 8 YEARS. I'M EXTREMELY DISAPPOINTED THAT THE SUSPENSION CONTROL ARM HAS FAILED WITH SUCH LIMITED USE WHICH CLEARLY SUGGESTS DEFECTIVE QUALITY FROM TOYOTA. RESEARCHING ON THE INTERNET (SEARCH STRING - SIENNA CONTROL ARM PROBLEM) I FOUND OUT THAT THIS IS COMMON ISSUE ON SIENNA TO THE POINT IT LEADS EM TO BELIEVE THIS SHOULD HAVE BEEN A RECALL E.G. HTTPS://WWW.SIENNACHAT.COM/THREADS/2011-SIENNA-SE-DEALER-RECOMMENDS-REPLACING-CONTROL-ARMS-LOWER-BALL-JOINTS.62597/. THIS APPEARS TO BE RECURRING ISSUE WITH SIENNA, HENCE I'M FILING THIS RECALL REQUEST/COMPLAINT.

TL* THE CONTACT OWNS A 2013 TOYOTA SIENNA. THE CONTACT STATED THAT WHILE DRIVING AT VARIOUS SPEEDS, THE REAR PASSENGER'S SIDE SLIDING DOOR OPENED INADVERTENTLY WITHOUT WARNING. THE CONTACT THEN TURNED OFF THE AUTOMATIC SLIDING DOOR FEATURE HOWEVER, THE DOOR AJAR AUDIBLE SOUND PERSISTED. THE VEHICLE WAS NOT DIAGNOSED NOR REPAIRED. THE MANUFACTURER HAD YET TO BE NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 73,000.

EXCESSIVE WEAR ON TIRE ALWAYS. 4 YEARS AND 4 SETS OF HIGH MILEAGE TIRES. NEVER GOTTEN PAST 20K ON A BRAND NEW SET. GOODYEAR ASSURANCE AND MICHILINE DEFENDERS. TRACTION IS ALWAYS AN ISSUE AT THE 12K MARK. ALLIGHNMENTA DONE EVERY TIME AND ROTATIONS EVERY 5K.

BINDING AND NOISE IN THE STEERING WHEEL WHEN TURNING LEFT OR RIGHT AND ACCELERATING FROM A STOP.

HAVING A PROBLEM WITH TOYOTA SIENNA TIRES, EVERY 30K, I HAVE TO CHANGE NEW TIRES FOR MY SIENNA VAN. TIRES WON'T LAST FOR LONG EVEN THOUGH AM DOING A REGULAR WHEEL ALIGNMENT EVERY 5000 MILES AND ALSO WATER PUMP HAD TO REPLACED WITH NEW WATER PUMP. IT'S COST US A LOT. I DID LOT OF REPAIRS ON MY SIENNA VAN, I HAVE ALMOST SPENT $10,000 FOR REPAIRS WORK AND TOTAL MILEAGE ON MY VAN IS NOT YET REACHED 90K

WHEN TRAVELING AROUND 30 TO 35 MPH (WELL UNDER SPEED LIMIT) ON DRY CLEAR ROADS, ON LEFT TURNS (OFTEN SLIGHTLY DOWNHILL) SUDDENLY THE VSC AND SLIP/TRAC LIGHTS UP, THE ABS SYSTEM IS ACTIVATED / BRAKES ENGAGE. FOOT IS NOT ON THE BRAKE AND SPEEDS ARE NOT EXCESSIVE. I AM NOT USING RUN-FLAT TIRES, BUT THAT DOESN'T SEEM TO MAKE A DIFFERENCE FOR OTHERS ONLINE. I SEE DOZENS OF SIMILAR COMPLAINTS ONLINE ABOUT THIS SAME THING FROM 2001 TO 2015 SIENNAS. TWO SAY THAT REPLACING RACK & PINION FIXED IT; 1 SAYS IT DOES NOT. THIS STARTED HAPPENING ABOUT 3 MONTHS AGO, BUT IS NOW HAPPENING MORE OFTEN. APPROX 156K MILES. OTHER FIXES THAT HAVE NOT WORKED: REPLACE FRONT SPEED SENSORS, CHANGED ALL PADS AND ROTORS, AND REPLACING THE STEERING ANGLE SENSOR. NONE OF THOSE WORKED. ON PERSON SAYS, "MOST COMMON PROB SEEMS TO BE THE RACK BUSHING WHERE THE RACK IS MOUNTED. THEY WEAR OUT AND CAUSE THE RACK TO MOVE WHEN TURNING...BUSHINGS ARE HARD TO REPLACE SO JUST REPLACE THE RACK AND IT WILL SOLVE THE PROBLEM IF IT IS LOOSE. ( ALTHOUGH ITS A BIT EXPENSIVE) THE YAW SENSOR OR STEERING SENSOR HAS ALSO BEEN THE CULPRIT IN SOME CASES." ANOTHER SAYS, "STEERING LINKAGES COULD BE ANOTHER CULPRIT - CONTROL ARM BUSHINGS WERE SEVERELY WORN AND COULD POTENTIALLY BE ANOTHER SOURCE. ALIGNMENT AND ZERO-POINT CALIBRATION SOMETIMES HELP, BUT NOT FOR LONG." I DON'T FEEL SAFE DRIVING MYSELF OR MY CHILDREN IN THIS CAR, BUT CAN'T AFFORD ANOTHER. AND CAN'T AFFORD A $1K FIX - ESPECIALLY IF OTHERS HAVE THIS ISSUE. WHAT CAN I DO?

THE REAR DIFFERENTIAL IS CAUSING A WHIRLING SOUND. THE SOUND ONLY OCCURS WHEN THE VEHICLE IS ON DRIVE. I DON'T HEAR THE SAME HIGH PITCHED WHIRLING SOUND WHEN THE CAR IS IN REVERSE. THIS IS A COMMON PROBLEM WITH THIS GENERATION OF SIENNA. TOYOTA HAS A RECALL FOR THIS ISSUE ON THE RAV 4 BUT NOT THE SIENNA.

VAN STARTED HAVING A PROPANE/MUSTY SMELL INSIDE CABIN WHILE DRIVING ON HIGHWAY. VAN JUST HAD CABIN FILTERS REPLACED AND AUTO SHOP STATED THE REAR DIFFERENTIAL AND COUPLER WERE BLOWN AND TO GET A USED PART AND REPLACE IT WOULD BE $4300. THE VAN IS A 2013 WITH 86,000 MILES ON IT. THE RAV-4 HAS THE EXACT SAME PART UNDER A RECALL. HOW DIFFERENT COULD THE PARTS BE IN THE SAME COMPANY FOR 2 VEHICLES LIKE THIS? IT SEEMS LIKE TOYOTA SHOULD BE ISSUING A RECALL FOR THIS PROBLEM AS I JUST READ ABOUT 6 OTHER PEOPLE WHO HAD THE EXACT SAME PROBLEM IN THE LAST 6 MONTHS ALONE ALL WITH VEHICLES WITH RELATIVELY LOW MILEAGE. THIS IS A DISSERVICE TO LOYAL TOYOTA CUSTOMERS AND A HUGE SAFETY ISSUE TO PEOPLE DRIVING THEIR FAMILIES IN THESE MINI-VANS.

REAR COUPLER FOR REAR DIFFERENTIAL BEARINGS ARE GRINDING CREATING WHIRRING NOISE AND NEED TO BE REPLACED BY DEALER. *TR

FUEL PUMP SOMETIMES STOP WORKING INTERMITTENTLY, WHICH COULD LEAD TO A SUDDEN STALL OR HESITATION WHILE DRIVING. THE PROBLEM INCREASES THE RISK OF A CRASH, ESPECIALLY WHEN THE MY SIENNA VAN IS TRAVELING AT A HIGH SPEED. WHEN FUEL PUMP FAILS, I NOTICE THAT THE VEHICLE'S ENGINE STARTS RUNNING ROUGH AND THAT WARNING LIGHTS MAY APPEAR ON THE DASHBOARD. THE ENGINE MIGHT NOT RESTART IF IT STALLS. *TR

NOISE FROM REAR DIFFERENTIAL. BEARING IN THE VISCOUS COUPLER APPEARS TO BE BAD AND A COMMON ISSUE-TOO COMMON FOR THIS TO NOT BE A RECALL.
