“The passenger-side power sliding door system failed to stop or reverse when it encountered physical interference with the vehicle’s open fuel door. The door continued opening under power despite clear obstruction by a fixed exterior body component. The affected components, including the sliding door mechanism and damaged fuel door latch, remain available for inspection upon request. A powered sliding door continuing to operate against an obstruction creates a foreseeable risk of injury to occupants or bystanders, as well as vehicle damage. If a person’s hand, arm, or clothing had been in the same position as the fuel door, injury could have occurred.

The issue has been formally reproduced or confirmed by an independent service center which noted that the incident occurred as described during normal operation of the power sliding door, and no abnormal conditions were present at the time.

“On November 30, 2026 approximately 12:15 pm, I was driving my 2014 Toyota Sienna in Santa Rosa California when the engine stalled while driving at approximately 20 miles per hour, luckily it did not happened on the freeway. I was turning left from Montgomery Dr onto Hahman Dr, the traffic slowed down and I hit the breaks, then the engine stalled. I quickly shifted the car into park position and restarted the car and proceeded to my destination at Montgomery village shopping center. It was a scary situation. This is the second time this has happened. The first time my wife was driving it and I don't know the details. What I know from my wife testimony is that the engine stalled while dropping out kid's at school. I would like for Toyota to address this safety concern.”
