The seat belt latch stopped working. It appears the locking mechanism failed and it is stuck in the locked state which prevents the seat belt from latching. This is a critical failure in vehicle safety. It had been inspected by Toyota and they do not know what happened and are not willing to fix it unless we pay for it. This issue should be a recall.

What 2023 Toyota Sienna Hybrid owners say
Most recent owner complaints, unedited.
My 2023 Toyota Sienna LE has experienced a recurring Supplemental Restraint System (SRS) airbag warning that appears to be triggered by normal movement of the second-row seats. The vehicle has been brought to Cobb County Toyota in Georgia multiple times for this issue. Previous repairs included replacement of the wiring harness. Following that replacement, the warning disappeared for a period of time. However, the SRS warning recently returned after I moved the second-row seats forward during normal vehicle use. I am concerned that the seat wiring, electrical connections, or related components may be vulnerable to strain or disconnection during normal seat adjustment. Despite previous repairs, the underlying issue appears unresolved. This is particularly concerning because an SRS malfunction may compromise the proper operation of the vehicle's airbags or other supplemental restraint components during a collision. I believe this warrants investigation as a potential safety defect involving the second-row seating and supplemental restraint system. I am requesting that the federal safety agency review the recurring nature of this problem, particularly its apparent relationship to routine second-row seat movement.
The contact owns a 2023 Toyota Sienna Hybrid. The contact stated that when attempting to apply the brakes while driving at 30 MPH or at lower speeds, the vehicle suddenly lunged forward. The failure occurred approximately 7 times, with the most recent occurrence causing the vehicle to lunge into an intersection, where oncoming traffic managed to avoid a collision. On that same day, the failure occurred 3 to 4 times. The vehicle was taken to the dealer, where the failure was diagnosed, and the contact was advised that a software update titled "Braking Comfort" was available to improve brake performance; however, the software update was not performed. The failure mileage was approximately 35,400.

While drive I'm approaching my driveway at about 20 MPH i proceed to turn into my drive and the car does stop or slow down it's like I'm on ice (very scary) Toyota says this is common on hybrids it seems to scary to drive
When I driving slow and begin to brake the car does not slow down or stop. It feels like I'm hydroplaning.
Seatbelt intermittently would latch since purchasing vehicle, and then completely failed and will no longer latch/clip in. This is 3rd row passenger side.
While driving on the freeway with my small children in the backseat a loud pop sounded and glass from the moon roof came shattering down upon us. The glass hit my face, arms, hair, and fell into my seat and all around the interior of the car. Though glass fell along my face my vision was not obstructed and I was able to safely exit the freeway without accident. The glass, though did make its way towards the backseats, did not hit my children. There was no warning or issues with the car or window.
On June 11, 2026, a BraunAbility Turny Evo seat system, installed by a third-party mobility dealer, suffered a catastrophic mechanical failure while in operation. A passenger with a physical disability was secured in the equipment when the mechanism seized, trapping the individual mid-cycle. The remote control displayed a mandatory "Code 19" error, rendering the equipment unresponsive and creating an immediate safety crisis. Beyond this mechanical failure, the vehicle's structural integrity is compromised. The floor plates and railings, which are critical for the securement of this mobility equipment, are loose and rattling, posing a severe risk of detachment while in motion. Furthermore, the interior upholstery was permanently damaged during the installation process, and a secondary mobility hoist system—which was paid for in full—was never installed. The dealer and the manufacturer have been notified of these dangerous structural and mechanical defects but have failed to provide a safe, complete repair. The vehicle is currently unsafe to operate and poses a direct threat to the safety of the passenger.
The brakes on the hybrid system release during braking. Which send the van lurching forward, this typically happens a lower speeds, under 20mph. Which makes it unsafe as you do not stop when you are expecting.
