What stands out
Owners have filed 42 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.
Body accounts for 26% of all owner complaints filed against this vehicle, across 12 categories tracked.
The failure pattern owners describe
Buyer takeaway: The 2014 Sienna has well-documented sliding door latches that can fail unexpectedly while driving, potentially opening fully and ejecting occupants—a serious safety defect. Buyers should inspect both sliding doors for corrosion, test power operation thoroughly, and verify any recall repairs have been completed with actual new parts, not just reused assemblies.
Owners of 2014 Siennas report sliding doors that open while driving—sometimes fully, sometimes intermittently, sometimes refusing to close at all. One owner's door popped open in an intersection at speed while accelerating; Toyota's own latch replacement didn't solve the issue and Toyota admitted they couldn't guarantee it wouldn't happen again. Multiple owners report doors that open after sitting parked, or doors that partially close then reverse and reopen. A handful report both sliding doors failing simultaneously.
NHTSA Campaign 16V858000 (body structure) addresses this defect, but many owners waited months for recall parts that remained unavailable. Some dealers told owners the failure was "collateral damage" too expensive to fix. One owner of a handicap-equipped van found the interim solution—operating doors manually—unacceptable and Toyota offered no accommodation.
Related failures include corroded door latches, snapped power cables rendering doors too heavy to operate, and a design flaw where the sliding door's safety plunger exerts such pressure on the fuel door hinge that the hinge breaks, trapping occupants if the fuel door isn't fully closed. One owner reported a power sliding door that didn't stop when hitting an open fuel door, raising foreseeable injury risk.
Liftgate struts fail and cause the gate to crash down unexpectedly. Water also leaks into cabins through windshield cowl seams, soaking carpet.

Failure modes owners describe
Sliding door opens while driving
Sliding door latch fails and door opens fully while vehicle is in motion, door alarm sounds. This is a life-threatening defect — passengers, especially children in booster seats next to the doors, face ejection risk. One owner tied the door shut to prevent recurrence after dealer replacement of latch assembly. Another owner reported both doors opened at 70 mph. Owners also report doors opening unexpectedly after parked, then refusing to close or only partially closing.
When: Occurs after several miles of driving; varies by owner report from 35,000 to 99,500 miles
Symptoms owners cite: Door alarm sounds / door ajar warning; Sliding door opens fully while vehicle in motion; Door opens unexpectedly when parked; Door will not close or stops/reverses mid-close cycle; Door difficult or impossible to open or close
Repairs/costs cited: Latch assembly replacement attempted; dealers have provided replacement parts with different model numbers but cannot confirm if parts actually differ or whether replacement fixes root cause. Multiple owners report repair attempts unsuccessful or unavailable.
Recalls/TSBs owners mention: NHTSA Campaign 16V858000 (Structure/Body) issued for sliding door defect; Toyota acknowledges knowing about the issue but cannot guarantee doors will not open while driving again; many owners report recall parts unavailable for extended periods; some report Toyota told them failure was 'collateral damage' and more cost-effective to drive vehicle as-is; interim recommendation to operate doors in manual mode deemed unacceptable for handicap vehicles with ramps
Power sliding door cable fracture or mechanical failure
Door cable snaps, rendering power door inoperable. Door becomes extremely heavy and can only be opened/closed manually thereafter. One owner's son bumped a sensor causing door to freeze halfway open; cable had snapped. Another owner reported fractured cable at 70,000 miles.
When: 70,000 miles reported in one case; timing variable
Symptoms owners cite: Door will not open or close using power/button; Door extremely heavy when operated manually; Door freezes in partially open position; Visible cable breakage
Repairs/costs cited: Door must be operated manually; one owner unable to open door at all after cable failure
Recalls/TSBs owners mention: Local dealers and manufacturer notified but did not assist
Sliding door latch corrosion
Two latches corroded, rendering doors inoperable. Owner reports corrosion visible at 18 months and 66,000 miles despite vehicle parked in garage 8–9 hours weekdays. Corrosion continued even after owner applied WD-40. Owners note if door assembly fails completely, risk of door closing on person, especially on hills.
When: 18 months to 66,000 miles
Symptoms owners cite: Visible corrosion on door latch assembly; Door closure issues; Door assembly degradation
Repairs/costs cited: Dealer refused to perform repair; owner applied WD-40 as temporary measure; no permanent repair recorded
Recalls/TSBs owners mention: Dealer declined to address; no manufacturer response recorded
Fuel door hinge failure due to sliding door safety switch pressure
Upper hinge of fuel filler door breaks because the sliding door safety switch (a plunger mechanism) exerts excessive pressure on the fuel door from inside, warping or flexing the door away from body. This prevents opening of rear passenger sliding door when switch cannot be fully depressed. Occurs at approximately 80,000–81,000 miles. Creates emergency egress safety issue — occupant unable to exit vehicle in emergency if fuel door is not fully closed. Documented on Sienna forums as known issue affecting multiple vehicles.
When: 80,000–81,000 miles
Symptoms owners cite: Upper fuel door hinge breaks or comes loose; Fuel door warped or flexed away from vehicle body; Excessive pressure/resistance when depressing safety plunger; Driver-side sliding door will not operate until plunger is fully depressed; Fuel door cannot be opened normally
Repairs/costs cited: Repair estimate approximately $380; neither Toyota nor extended warranty would cover; owners note design defect rather than wear issue
Recalls/TSBs owners mention: No manufacturer recall or service bulletin; dealers refuse coverage citing design as not defective
Power sliding door fails to stop or reverse when obstructed
Power sliding door continues to open under power when encountering physical obstruction (fuel door in this case), without reversing or stopping. No safeguard, interlock, sensor logic, or warning prevents operation against fixed body component. Poses foreseeable injury risk if occupant hand, arm, or clothing in path. Independent service center confirmed door operated as described with no abnormal conditions or warning signs present beforehand.
When: During normal vehicle operation
Symptoms owners cite: Power door continues opening despite obstruction; No automatic reversal or stop when door encounters resistance; No warning light or message before failure
Repairs/costs cited: Affected components (sliding door mechanism and fuel door latch) available for inspection; owner identifies this as design deficiency not maintenance issue
Recalls/TSBs owners mention: No manufacturer response recorded; owner characterizes as design deficiency warranting evaluation across similar power sliding door systems
Rear liftgate struts fail; gate closes unexpectedly
Power rear liftgate struts fail to support gate; gate crashes down unexpectedly, creating injury hazard if person standing beneath. Affects 2004 Sienna (different model year in complaint narrative #6) but indicative of similar body component failures in Sienna line. Voluntary Toyota service campaign (08V244000) repair period ended in 2010; dealer quote ~$500 for repair; Toyota declined warranty coverage claiming campaign expired.
When: Varies; struts fail over time
Symptoms owners cite: Liftgate struts no longer support gate weight; Gate crashes down unexpectedly; Gate closes on occupant if standing underneath
Repairs/costs cited: Repair involves liftgate strut replacement, approximately $500 at dealer
Recalls/TSBs owners mention: Voluntary service campaign 08V244000 (not a recall); repair period ended 2010; no coverage after campaign period
Water leak into cabin from windshield cowl
Water leaks into cabin from below front windshield cowl area, soaking entire cabin carpet. Musty smell precedes discovery of wet carpet. Issue persisted even after AC lines were drained. 'Water Doctor' diagnostic service located leak source and applied sealant; carpet padding replaced and cabin deodorized.
When: Timing not specified; repair performed in September–October 2018
Symptoms owners cite: Musty smell in cabin; Entire cabin carpet soaking wet; Water continues entering cabin even after AC drain service
Repairs/costs cited: AC line drain, sealant application to cowl area, carpet padding replacement, cabin deodorization; total repair cost $551.20
Recalls/TSBs owners mention: No manufacturer response recorded; owner paid out-of-pocket
