-Multiple instances recently of feeling like the car was accelerating or lurching forward lightly while I was braking - thought I was going crazy. Today however, the car very clearly lurched forward while I was braking coming into an intersection with my kids in the car. Checked my foot on the pedal, mats, etc. Will be taken to dealer on earliest appointment they have in 7 days. -If there was a car coming through that intersection, my family and I could have been T-boned due to the unexpected acceleration. -There are no warning lamps or messages active in the vehicle. -Symptoms likely started a few months ago, but the most severe instance was today, 9/16/2024. I finished driving my kids to soccer and while there I googled this and called my dealer. Apparently this is a known issue? -How can Toyota not notify owners of this serious issue? There needs to be a recall immediately. This is my family vehicle that we bought new just a few years ago, this is dangerous and absolutely unacceptable.

Intermittently and randomly the vehicle will lunge forward with the brake applied. I engage the brake, the vehicle slows and then lunges/lurches forward as if I were not braking. Not only is this terrifying but it is also extremely dangerous. This has happened many times since purchase in February 2021 and continues to now.

Today, it caused the van to not be able to stop in time and the van finally came to a stop in the middle of a four way intersection. I did a Google search.

Acceleration or surge seemingly while transitioning from regenerative braking to friction braking. Observed numerous instances where at slower speeds, after removing my foot from the accelerator and beginning brake application, a surge or acceleration occurs. In these instances I ensured that my foot was NOT contacting the brake and accelerator simultaneously. There is a distinguishable surge in driveline when this occurs. The surge may also be caused or exacerbated by a change in driveline power (engine/battery) occurring simultaneously with the transition from regenerative to friction braking. One of the most concerning instances of the anomaly occurred while turning. When making accelerating, coordinated turn and expecting the vehicle to respond appropriately by decreasing speed, it instead momentarily accelerated. This caused great concern and a moment of panic as I had to immediately react to avoid striking other vehicles or obstacles because my intended path of travel changed as a result of this surge. Since this report of surging of the Sienna Hybrid is also reported by other owners on various forums, I’m willing to have additional sensors installed to enable ample recording of these events. This should be considered a safety event.

There is a recall on the passenger side airbag sensor of this vehicle. The time it is taking to get it fixed is UNACCEPTABLE. Toyota makes new vehicles with working components. They care more about money than lives. Since the recall includes the air bag, people will die before this gets fixed. Toyota's solution is to tell us to not use the front passenger seat. That is ridiculous; this is a family vehicle and all seats are needed. We have contacted Toyota twice in which we have been advised to rent a car - for 2 years - and we will "probably" be reimbursed - after the recall is all fixed. We do not have the space for another car or the desire to put that much money up front into a rental car. We could sell the van and buy a newer one but would lose a lot of money in doing so, nor could we in good conscience sell this vehicle to anyone else. In our latest conversation with Toyota, we were told that the first customers to have access to the recall fix would be this September, but since we live in Utah, it would not be available to us until 2026! What? That is DISCRIMINATION. If the fix is available, it should be given to all who need it. I can't believe how Toyota is treating their customers, especially when the recall can be life-threatening.
