2023 Toyota Sienna Hybrid problems

“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.”

“The contact owns a 2023 Toyota Sienna. The contact stated that while driving, the fuel gauge indicated there was 121 miles of fuel available. The contact stated that within twenty miles, the fuel gauge indicated that the fuel tank was empty. The contact stated that when the gauge indicated 170 miles available, the fuel usage decreased quickly. In addition, the contact stated that the failure had occurred several times. The contact stated that the vehicle was purchased and modified for transporting the contact’s disabled son. The Freedom Motor company provided the modification requests. The contact stated that the vehicle was taken to the modification company several times, however no assistance was provided. The contact was advised to always keep the fuel tank full. The contact stated that it was very hot and dangerous to be driving a vehicle and running out of fuel while transporting her disabled son. The manufacturer was not made aware of the failure. The failure mileage was unknown.”

“Vehicles equipped with rear entertainment: when tv is folded down, Toyota failed to include a digital mirror to support the ability to see through the rear of the vehicle. When the entertainment system is folded down, the rear view mirror is inaccessible. Many reports are filed online describing the same issue by other owners. Recall should be made to fix the issue and have a digital mirror put in place.”

“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.”

“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 NHTSA review the recurring nature of this problem, particularly its apparent relationship to…”

“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.”
