What stands out
Owners have filed 39 body complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
No new NHTSA body complaint has been filed on this vehicle in over 8 years — the issue may be aging out of the active population.
The failure pattern owners describe
Buyer takeaway: The 2012 Sienna has serious power sliding door defects: doors open without warning while driving, cables break, latches fail, and sensors are inadequate to stop doors on occupants or objects. A major recall (16V858000) has been outstanding since late 2016 with parts unavailable—owners face year-plus delays or are stuck with manually operated doors. Rear liftgate misalignment, water intrusion, and hinge rust round out a pattern of poor body assembly and durability.
The 2012 Sienna's power sliding doors are the focal point of 39 complaints, centered on NHTSA Campaign 16V858000. Owners describe rear and driver-side doors opening unintentionally while driving at speeds from 15 to 40 mph, with no fault codes or warning lights. Dealers cannot replicate the failures; one suggested disconnecting the door fuses as a permanent workaround. The root cause remains undiagnosed.
Mechanical failures compound the problem: door cables fray, break, or snap; motors fail to engage; latches rust and corrode; and doors jam mid-stroke. Replacement costs quoted at $1,200–$2,000, often denied under warranty. Some owners resort to manual operation after disabling the electric mechanism—but manual doors slide rapidly and have closed on children's hands.
Equally troubling: the sliding doors lack adequate safety sensors. One owner's dog was trapped in a 3–4 inch gap between door and body for ten minutes while the motor continued cycling; another owner was nearly crushed when the rear hatch closed on her despite full resistance. Owners note that competitor minivans (Chrysler Town & Country) stop instantly on obstruction.
The recall, issued November 2016, remains unfixed. Dealers report parts unavailable through 2019 and beyond, with no timeline from Toyota for availability. Service appointments stretched 12+ months into the future.
Secondary issues: rear liftgate misalignment causing water ingress, hinge rust, and electrical glitches (door ajar warnings at low speeds). One owner also reported door failures after minor quarter-panel damage, raising questions about structural durability in accidents.

Failure modes owners describe
Power sliding door unintended opening
Rear and driver-side power sliding doors open while driving or parked without owner input, sometimes at highway speeds. No fault codes or sensor fault detected in diagnostic attempts.
When: Various speeds from 15–40 mph while driving; also while parked. Mileage range: 23,500–82,000 miles.
Symptoms owners cite: Door slides open without warning while driving; Door opens unexpectedly while parked; Recurrent opening on same door; No warning lights or fault codes; Owner unable to stop door once it starts opening
Repairs/costs cited: Dealer unable to replicate failure or diagnose root cause. Manufacturer suggested disconnecting electric door fuses as interim workaround.
Recalls/TSBs owners mention: NHTSA Campaign 16V858000 (Structure). Recall issued but remedy parts unavailable for extended period. Manufacturer suggested temporary fix: remove fuses to disable doors.
Power sliding door cable failure and mechanical breakdown
Passenger and driver-side power sliding door cables break, fray, or fail. Doors become inoperable or partially stuck. Motor damage reported by dealership after owners forced door closed.
When: Mileage range 23,500–82,000 miles. One case with clicking noise starting at 73,000 miles.
Symptoms owners cite: Cable breaks or frays; Abnormal clunking or clicking noise; Door fails to close with automatic button; Door stuck mid-operation; Owner must manually close door; Motor fails to engage properly
Repairs/costs cited: Replacement of door motor, cable, and door assembly quoted at $1,200–$2,000. One owner disabled electric mechanism and manually closes door (unsafe—door slides rapidly). Dealer denied warranty coverage; charged owner for 'damage from forcing door.' Parts frequently unavailable per recall.
Recalls/TSBs owners mention: NHTSA Campaign 16V858000 (Structure). Recall issued November 2016; parts unavailable for repair through at least 2019. Manufacturer unable to confirm parts availability timeline.
Power sliding door fails to latch or close properly
Rear sliding doors will not latch, close completely, or stay closed. Doors open and close unexpectedly while driving or parked. Latch mechanism fails intermittently or completely.
When: Mileage range unknown to 201,235 miles. Failures reported from initial ownership through high mileage.
Symptoms owners cite: Door will not close or latch; Door slides open and closed while driving; Door fails to stay closed; Door opens while owner driving; Intermittent latch failure
Repairs/costs cited: Dealership repair attempted; some cases not repaired due to unavailable parts or warranty expiration. Owner cut cable and resorted to manual operation (unsafe).
Recalls/TSBs owners mention: NHTSA Campaign 16V858000 (Structure). Parts unavailable; no timeline provided by manufacturer.
Rear liftgate misalignment, clunking, and water intrusion
Rear liftgate misaligned from factory or after service. Clunking noise on closing. Water leaks through top of liftgate under pressure (carwash). Dealership dismissed multiple service visits and blamed prior quarter-panel damage.
When: Reported during warranty period and with extended warranty coverage. Owner visited dealership three separate times.
Symptoms owners cite: Clunking sound when liftgate closes; Liftgate visibly misaligned; Water entry through top of liftgate under pressure; Noise progresses over time
Repairs/costs cited: Dealership declined realignment under warranty, blaming owner's prior tree impact and quarter-panel repair. Owner concerned about water damage to auto-open mechanism if not corrected.
Rear sliding door latch rust and corrosion
Rear sliding door latches and hinges rust and corrode despite vehicle age. Latch becomes inoperable and breaks off. Owner reports latch is not stainless steel while driver door latch is.
When: Reported at various mileages. One case explicitly tied to freeze-thaw cycles (rained, froze, snowed, thawed).
Symptoms owners cite: Visible rust on latch mechanism; Latch corrosion near door cables; Latch breaks off; Door will not open or close properly; Hinge starts to rust
Repairs/costs cited: Toyota quoted $1,400 to replace latch. Owner questioned why sliding door latch is not stainless steel like driver door latch. No repair done; owner managing with disabled sensor beeping.
Rear sliding door lack of safety sensors and entrapment hazard
Rear power sliding doors lack adequate obstruction sensors compared to competitor vehicles. Door continues closing on occupant, animal, or object with no resistance detection. One case: dog's body trapped in 3–4 inch gap; owner had to disconnect battery to stop door. Another case: owner nearly crushed while positioning items.
When: Incident mileage unknown but vehicle in active use.
Symptoms owners cite: Door closes on obstruction without stopping; No sensor stops door when contacted by object or body part; Owner cannot stop door by pulling against it; Door continues to slide forward and backward despite resistance; Dangerous entrapment gap (3–4 inches) between door and vehicle body

Driver and passenger side power sliding door occasionally (I.e. Not all the time) makes an abnormal pop noise when initially opening with the outside handle or with the inside handle on the sliding door. This does not happen the door is opened with other method (e.g. Remote, over-head mount control, button on b-pillar). It seems as if the door doesn't unlatch before the motor start pulling the…
I have brought the sienna into Toyota on 3 separate occasions, as it was clunking when it closed. I was told there was nothing wrong with it each time, but the liftgate was clearly not aligned. Water is now coming through the top of the lift gate. I did back up into a tree, and had damage to the back quarter panel and it was repaired by a body shop. Toyota is stating that this caused the…
