Van purchased new October 2024. On two separate occasions, one in late 2024 and next today, [XXX], when pulling into street from a stop, there is no throttle response. You push the accelerator at varying pressure and no response for 2-3 seconds. This is a severe safety issue as it could cause an accident with oncoming traffic. No error lights illuminated on dash. Have seen other complaints on NHTSA website and social media as well. Will take to dealer but reporting a major safety issue.

When crossing a one-way road with oncoming traffic from the left, a vehicle that has recently passed might be triggering the forward collision avoidance system which cuts off throttle control to the Sienna, even when the passed vehicle is well out of the way. It is unknown if the collision avoidance feature is being triggered as there are no warning lights or messages in the display. This results in the Sienna having no accelerator response and sitting -??dead in traffic-?? sideways in front of oncoming cars. This this is the second time this issue has occurred and today I was nearly t-boned by on-coming vehicles as there was no throttle response to move the car forward. This issue has been reported in 4th generation Sienna (-??21--??24) forums on Facebook. This issue puts at risk vehicle occupants as well as other vehicles on the road.

Vehicle was driving on a slow traffic local street at roughly 10MPH. Spacing between car in front of me was around 30 ft. I was gliding towards front and ready to brake. Suddenly the vehicle start to accelerate hard by itself without driver-??s operation. I tried to engage brake / gas pedal and was not helping. Front collision system did not activate like it suppose to. I ended up turn sharp right towards road curb and hit pole at average speed of 30mph or less. No air bag deployed. I then switch to Park. No warning lights pop up. All safety features on vehicles were turned on before the incident. Whats weird is the car is functioning normal now after incident. I contacted Toyota USA and waiting for feedback.
