Below are recalls and complaints reported to NHTSA for the 2026 Toyota Sienna. This information is consumer-reported and provided for general informational purposes only. Vehicles like this may qualify under California lemon law depending on their individual repair history.
The following are consumer-reported complaints filed with NHTSA. These are unverified allegations and are not proof that any defect exists.
Less than 1000 miles on my car i do not remember exact dates hence i have added todays date for incident date.All three incident happend in three different days. Scenario 1 two times. Scenario 2 one time --- SCENARIO 1: Curved Road / No Lane Markings --- Conditions: ACC set at 25 MPH on an undivided two-way road with no lane markings. Parked vehicles present at curves; oncoming traffic at safe distance. Issue: On two separate occasions, the vehicle applied sudden, significant braking without driver input while navigating curves. No imminent collision risk existed. The abrupt speed reduction created a rear-end hazard from following traffic. Reported to Toyota support: YES --- SCENARIO 2: Michigan Left Turn Lane / 40 MPH --- Conditions: ACC active at 40 MPH on a multi-lane road with a dedicated Michigan Left turn lane. Forward path in my lane was clear. Issue: A vehicle ahead moved into the Michigan Left turn lane and began decelerating. As my vehicle accelerated (path now clear) and was still slightly behind — approaching but not yet parallel to — the turning vehicle, the system applied brief unexpected braking. The turning vehicle then moved further forward to complete its Michigan Left maneuver ; my vehicle resumed normal speed when some diagonal distance had been seen. Reported to Toyota support: NO ACTION REQUESTED: Investigate whether Toyota Sienna's PCS/ACC (1) miscalibrates object detection on unmarked curved roads and (2) fails to distinguish lateral vehicles from forward obstacles. Software update or remedy may be warranted.

While slowing to a stop sign at a normal speed, the 3rd row, which does not lock into place, flew into the upright position. Thankfully it had nothing on top of it, but if it did my children in the second row would have been seriously injured.

The center console between the front seats has a design defect. When small objects such as a credit card, key fob, or coin are left on the flat surface of the console, they can slip through a gap into the internal storage compartment. Once inside, the object becomes lodged and physically blocks the console lid from opening, locking the owner out of the storage compartment. The console must be partially disassembled to retrieve the object. This is a design flaw, not operator misuse. The flat surface visually appears usable, and the owner's manual does not warn against placing objects there. This defect is widely reported in the "Toyota Sienna 2025+" Facebook group (the largest online community of current Sienna owners), where multiple owners report the same problem. The defect is therefore not isolated. The vehicle was purchased new on 01/22/2026 from Nourse Toyota. The dealer declined to repair and referred me to Toyota. Toyota Customer Experience (Case ID XXX, contact: [XXX], 06/04/2026) declined to offer a remedy. On 06/10/2026, the Toyota Brand Engagement Center (Case #XXX) confirmed in writing that no recall or Customer Support Program covers this issue, and that the diagnosis does not indicate a manufacturer defect. No warning lamps or messages appeared. The defect is mechanical. I request NHTSA review this defect for investigation and potential recall action.

The back up camera freezes. It will show old image not the live image. This creates a safety hazard when parking and reversing in school around kids and other people.

This minivan has the entertainment system, when using the TV screen, it blocks the rearview mirror where you are unable to see out of the back window. I have not seen any warning labels. I am unsure if it has been inspected by the manufacturer, and police and insurance reps have not inspected mine.

2dark areas on driver's side with low beams on. Very distracting when driving and almost hit road debris not visible due to dark areas. Having this as a standard feature on lights is dangerous for driving at night.
