“Husband lost control of the car driving 75 miled per hour on highway. Awd brake override. Contact dealership came on a gauge. Pulled off side of I-95 and car shook and came to a complete hault after making a loud grinding noise. We immediatley noticed fire coming from under the hood on driver side. Evacuated, called 911. Car was a total loss. Please get Toyota to investigate since this is not the first 2017 Toyota Sienna to catch on fire in the same manner.”
NHTSA complaint #11124206, filed 2018-09, 21,800 miles“I was driving on the interstate at approximately 65 miles per hour. My 'check all wheel drive system' warning alarm came on shortly followed by the: check engine, battery alarm, collision breaking system, etc. I'm certain there were more alerts going off; however I was trying to steer a car, that had lost power off the roadway. I was able to get the car safely onto the shoulder where I attempted to turn off the vehicle. I couldn't turn the car off until I realized I needed the car to be in park. …”

NHTSA complaint #11195303, filed 2019-04, 12,045 miles“Today 4/7/23 My 2017 Toyota Sienna accelerated on its own. I was driving my 4 children to school and we were at a stop light. When I took my foot of the brake to start making a turn the car gunned it around the corner. It scared everyone in the car half to death. Thankfully no one was hurt but it looks like others on here haven't been so lucky with this issue. I hope toyota does the right thing a d fixes this issue before more people die.”

The next day we authorized them to do a diognostic on it where they found a burnt airfilter and melted housing. …”
