It has been over 60 days since the recall was announced. There is currently no repair available and no estimate of when a repair will be available. I have been notified of the recall through the Toyota app, but have received nothing in the mail. Totoya representatives confirmed that my vehicle is affected. The welding on the middle seats may be compromised, making the middle seats unusable. This is greatly affecting not only the safety of the vehicle, but its use as well, since it is in essence now only a 5 passenger vehicle. I requested a buy-back on my two month old car from Toyota but the claim was denied.

The drivers side mirror vibrates causing distortion that makes it difficult to judge distances on highways. This issue seems to be a structural defect in the door not the mirror. Multiple people are complaining about this. Many have had the mirror replaced only to still experience the issue myself included. I have test drove two brand new 2025 Sienna and the issue was present there as well. It is very much a safety issue.

Transmission has failed and been replaced. This is part of issues from 2017 to 2020 tranny failures, loud whining and needing to be replaced. Tranny failure is very dangerous to the occupants. Toyota has failed to warranty these.

Subject: Safety Defect Complaint – 2017 Toyota Sienna (VIN: [XXX] ) Dear NHTSA Safety Division, I am submitting a safety complaint regarding my 2017 Toyota Sienna, VIN [XXX] . In June 2023, while traveling on I-81 South in Virginia with my family of seven, the van stalled suddenly and emitted white smoke from under the hood, then the engine completely failed. The vehicle had only 111,000 miles. The repair would have cost $15,000, and I had to sell the van in 2024 for $4,000, suffering significant financial loss. Toyota informed me no recall applies to my VIN, although many 2017 Siennas experienced fuel pump failures causing stalling. As a person with disability and serious health issues, this incident caused extreme stress, hardship, and risk to my family. I request that NHTSA investigate this potential safety defect to determine whether other 2017 Siennas are affected. Sincerely, Your Name Phone Number Address INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

WHEELS, SERVICE BRAKES, ELECTRICAL SYSTEM
Vehicle: 2011 Toyota Sienna XLE VIN: [XXX] Mileage: ~204,800 Incident Date: [XXX] Recent Service: Oil change, tire rotation, brake inspection, and multipoint inspection performed on November 10, 2025 at Fitzgerald Toyota Gaithersburg (Maryland). Description of the Defect: On [XXX] while driving with my child in the vehicle, my 2011 Toyota Sienna experienced a sudden and dangerous failure. A strong burning smell entered the cabin, the ABS warning light illuminated, and then wheels locked up while the vehicle was in motion. At the same time, the steering wheel locked, making the vehicle impossible to steer. The engine immediately lost power and shut down in the middle of the roadway. The vehicle would not restart and had to be towed. This failure occurred four days after dealership service at Fitzgerald Toyota Gaithersburg, which included an oil change, tire rotation, and brake inspection. The dealership initially claimed the failure was due to a “dead battery,” and the following day changed the explanation to a “shorted alternator.” A weak battery or alternator failure does not explain a mechanical wheel lock or steering wheel lock while driving. The dealership has refused to provide diagnostic documentation or photographs of the components involved. This incident presents a significant safety hazard, and if it had occurred at highway speeds, it could have resulted in a severe crash. I am reporting this to request investigation into a potential safety defect involving the steering system, braking/ABS system, electrical system, or related components. Safety Risk: High. Loss of steering control + wheel lock + engine shutdown presents an immediate crash hazard. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The sunroof leaks. Took vehicle to dealership. Was told they saw drops of water around the light housing. This could cause an electrical malfunction which could be a safety hazard. They could not find the source of the leak. There are other 2025 Sienna owners talking about their sunroofs also leaking. Thank you.
