2025 Toyota Sienna Hybrid Problems

What owners report

Nearly all of the sampled complaints for this model year concern one event: the second-row seat-rail recall (25V668000), which owners say leaves those seats unusable while they wait for parts. Complaints written from late 2025 into 2026 describe vans parked at dealers or swapped for rentals for months, with owners asking for a repair date or a comparable replacement vehicle. The remaining reports are scattered and cover mirror vibration, glass breakage and leaks, liftgate alignment, seat hardware, and brake feel, mostly at low mileage.

   Second-row seat rail recall with no remedy yet

   • 206 complaints (77%)
   • median 7,750 mi at 1.0 yrs old (6 state mileage, few)
   • 1 mention a crash, fire or injury
   • filed 2025–2026

   Owners describe being told that the second-row seat rails may have been welded improperly and that those seats should not be occupied until the repair is made. Many say the dealer confirmed remedy parts were not available, and that the van sat at the dealership or was replaced by a rental for weeks or months. Several families note they bought the van for second-row child seats and could not use it as intended, and some report the interim notice arrived well after the recall was announced. Complaints repeatedly ask for a repair timeline or an equivalent loaner vehicle. Reported mainly between late 2025 and 2026; where mileage was recorded, most vans were under 20,000 miles and some had only a few hundred.

   What to check: Ask whether recall 25V668000 has actually been completed on this specific van and get it in writing, since complaints describe parts being unavailable for extended periods. Confirm the second-row seats are usable and that every seating position works before buying.

   “I received a notification on my Toyota App in mid-Oct advising there was a recall due to the second-row seat being improperly welded. At that time, I was advised a repair was in work and to avoid using those seats. However, I have four children and require all the seats in my Sienna so I have been forced to continue to use the seats, despite the warning. …”

   Liftgate misaligned and hard to open

   Mentioned in 4 of 60 sampled complaints

   Owners describe the rear liftgate sitting unevenly in the opening, with a visible gap on one side and creaking while raising or lowering. Some say the liftgate is difficult to open with the remote or interior button and requires pulling by hand. One complaint mentions visits to several dealers without a resolution, and another says the trunk would not open with the fob or interior button. Reported in the first several thousand to about 11,000 miles, sometimes noticed shortly after delivery.

   What to check: Check the panel gaps around the liftgate on both sides, operate it with the remote and the interior button, and listen for creaking.

   “We purchased a used 2025 Toyota Sienna a few weeks ago. The other day, my husband put his phone and wallet into the center console compartment and closed the lid. When we went to retrieve those items, the lid only opened partially. We were finally able to remove the wallet but the phone had slid down into the compartment where the door to that console opening slides into when you open and close it. The lid would not open all of the way and blocked our access to that space when you opened it. …”

   Moonroof water leak into the cabin

   Mentioned in 4 of 60 sampled complaints

   An owner reports water entering through the moonroof and a dealer repair that did not stop the leak, with water still coming in after a car wash. The complaint notes the dealer described the leak as normal for the design and that video was captured showing the water. Reported early in ownership, within the first few thousand miles.

   What to check: Look for water stains or damp headliner around the moonroof and sun visors, and run water over the roof during an inspection if possible.

   “Moonroof on my new 2025 toyota sienna has water leaking in. I've brought it to the dealership to try to resolve this. They said they fixed it. But I've just got a carwash and I still water leaking in. I have video of this. It shouldn't leak or be design to leak like the dealer said.”

   NHTSA complaint #11673111, filed 2025-07

   “Difficulty in pulling the seats belt on the second row seats when the car is turned off. Child has no wiggle room once it’s fastened and cannot undo seat belt as there’s no room to reach to unbuckle belt. I have to force the seat belt out of booster seat so belt can retract completely. The third row seats had a similar issue but didn’t have to force to out of booster seat for it to work properly.”

Buying note. The main thing to settle before buying is the status of recall 25V668000 on the specific van: confirm the repair has been completed and that the second-row seats are usable. Beyond that, check the driver-side mirror at speed, the liftgate alignment and operation, and the sunroof area for leaks during a test drive.
