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)
