2017 Toyota Sienna Complaints

My 2017 Sienna has whine noise coming from transmission, the vehicle was inspected by Toyota dealership and confirmed that the noise is coming from Transmission. Toyota has already issued a recall for the 2017 Sienna with Transmission UA80 under program ZJC. My vehicle has the same issue, however, it is not being covered as it is UA80E. This issue seems common among all the 2017 model irrespective of transmission number. However, Toyota is not providing support to all customer and have limited to a only one transmission number.

The drivers side sliding door when on the power on, it will either not catch when opening or not shut when you are trying to shut it. You can be in the door way and it will shut on you by itself. You have to physically stop it or pull it shut. I have taken it in the past to the local Toyota dealership, when it was under warranty, multiple times. They don't see anything wrong, or cannot explain it but have replaced the sensor multiple times. It will be ok for a while and then start again. I sometimes wonder if cold weather affects it but there is no rhythm or reason to it. I am scared to have children or my parents use this door and if I turn off the power to it, it is very hard to use the door because it is so heavy. There are no warning lights, messages, or signals of any kind.

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...

I am writing to report a significant safety issue with my vehicle involving a leaking sunroof that is causing damage to both the seatbelts and airbags. I believe this issue poses a serious safety concern and could lead to malfunctioning safety systems during an accident. I asked my local Toyota dealership for guidance adn they told me to clean the drain tubes out with weed eater wire. We tried that and the drains were working fine. If that did not work, it would be 3-5 thousand dollars to fix it. I have reported this issue to Toyota cooperate, but they are not willing to acknowledge the issue because of the year and miles on my van. There are several other Toyota Sienna van owner that have experienced the same problem and yet a recall has not been issued. This is my family vehicle that I drive my young kids around in. I feel that Toyota is willing to put my family's safety on the line by not acknowledging this on going issue. Issue: The sunroof in my vehicle has developed a leak ove...
