The 2007 sienna van in question is one of many plagued by an array of door latch problems of many different varieties that were not covered under a very poorly executed so called 'recall' on this van. The whole design was poor from the start, and the consumer is getting taken to the bank by the dealers and the company. When they want a $1000 to fix one door that they know if faulty that's simply…

What stands out
No new NHTSA electrical complaint has been filed on this vehicle in over 9 years — the issue may be aging out of the active population.
The failure pattern owners describe
Buyer takeaway: The 2007 Sienna has well-documented rear sliding door problems—motors and latches fail frequently, parts melt from heat, and repair bills routinely hit $1,000–$1,700 per door with no guarantee the fix will hold. Avoid this model if you rely on functional sliding doors for daily use or child safety.
Owners report a cluster of electrical and mechanical failures in the 2007 Sienna's rear sliding door systems. Power sliding doors frequently fail to open or close automatically—some open on their own while driving, others won't respond to remote or interior controls. Latch assemblies seize up or fail entirely; owners cite door slides popping open during acceleration and wires snapping loose, leaving no manual override to exit the vehicle. Repair costs run $1,000–$1,700 per door from dealers; independent mechanics charge $245–$570 for parts alone.
A recurring and alarming issue: rear door latch rubber assemblies melt and become hot to the touch, exposing bare circuitry to fingers. Multiple owners report this as a fire hazard. Some latch handles fail completely and stop working altogether.
A separate electrical problem involves melted or failed door latch rubber components in freezing weather, rendering the rear tailgate inoperable—a safety concern if emergency egress is needed.
One complaint reports both driver and passenger sliding doors simultaneously stopping mid-use, with a snapped wire hanging from the rear window, leaving children unable to exit independently.
A DVD navigation system failure also disabled the backup camera in one vehicle. Another incident involved rear windows and vent windows failing to open, with parts on back order.
Owners report Toyota denied or delayed warranty coverage, citing design exclusions or wear-and-tear arguments despite low door-cycle counts.

Failure modes owners describe
Power sliding door motor and latch assembly failure
Rear sliding doors fail to open or close automatically; doors open on their own while vehicle is in motion or parked, or refuse to respond to remote or interior controls. Latch assemblies seize or fail entirely.
When: Various mileages; one at 45,000, another at 130,000 miles; failures reported 2012–2017
Symptoms owners cite: Door slides open during acceleration; Door opens on its own while parked or driving; Door will not close automatically; Door will not respond to remote control; Door will not respond to interior front controls; Latch assembly seized; Latch mechanism fails to pull door in and engage lock
Repairs/costs cited: Dealer quoted $1,700 for power sliding door motor and cable replacement; independent mechanic charged $244.80 for temporary fix (lubrication and removal/reinstallation); permanent part replacement estimated at $570.23 plus labor. Repairs often do not last long before problem recurs.
Recalls/TSBs owners mention: Toyota issued an 'extended warranty' for rear sliding door latch assemblies (9 years/120,000 miles from first use); however, owners report Toyota denied coverage on manual doors despite latch motor being present, citing design limitations. Recall on 2011+ models mentioned but not addressed on 2007 model.
Melted rear door latch rubber assembly and thermal hazard
Rear door latch rubber components melt and become dangerously hot to the touch, exposing bare circuitry beneath. Material coating fingers with hazardous substance when attempting to open door. Multiple owners and online reports cite this as a fire hazard.
When: Timing unclear; at least one failure occurred around December per one narrative; another at 130,000 miles
Symptoms owners cite: Rear door latch rubber assembly melts; Latch becomes hot to the touch; Bare circuitry exposed and accessible to fingers; Melted rubber leaves hazardous coating on fingers; Latch handle stops working entirely after melting
Repairs/costs cited: One owner reported using duct tape as temporary cover for melted handle. Door will not unlock after failure.
Rear sliding door wire/cable rupture
Wire or cable component in rear sliding door mechanism ruptures and protrudes from rear window area, rendering both driver and passenger sliding doors inoperable. No manual override available to open doors from inside.
When: At 130,000 miles
Symptoms owners cite: Wire snaps inside door mechanism; Wire hangs from back window area; Both driver and passenger doors become completely inoperable; No manual way to open doors from inside vehicle
Repairs/costs cited: Owner unable to afford immediate repair; children forced to climb from front to rear seats to exit vehicle.
Recalls/TSBs owners mention: Dealer attributed failure to 'wear and tear' despite low usage rate (1–2 door openings per day); Toyota not addressing without charging high repair costs
Rear sliding door thermal/freezing malfunction
Rear tailgate becomes inoperable in freezing weather conditions, linked to melted or failed door latch rubber components. Raises safety concern if emergency egress is required.
When: During freezing weather
Symptoms owners cite: Rear tailgate will not open in freezing temperatures; Latch rubber affected by cold and heat extremes
Recalls/TSBs owners mention: Recall issued for 2011+ models; issue on 2007 not addressed
