Sliding door defects dominate these complaints. Doors open unexpectedly while driving at highway speeds, fail to latch after closing, or require multiple button presses to shut. Some grind or pop during operation; one door slammed shut on a child's finger. After recall service, one door drew 2.4 amps continuously, draining the battery. A passenger door came off track and shattered the rear window despite prior recall work. Hinges rust out and fail—one door fell off at 113,000 miles even though the vehicle was always garaged.
The recall (16V-858000) has been plagued by parts shortages lasting months or years. Owners receive notices but cannot schedule repairs because dealerships lack components. Multiple owners report waiting 3+ months with no progress, and Toyota provided no timeline for availability. Some dealers refused repairs on vehicles with aftermarket handicap seats, contradicting the recall's promise of free service.
Water leaks into the cabin from windshield seals, sunroof edges, and door frames—one new van leaked within two weeks of purchase. A sunroof spontaneously shattered at 15,000 miles. Body trim detaches while driving. One owner reported a broken front-left subframe weld that Toyota has repeatedly declined to repair despite warranty coverage.
Failure modes owners describe
Power sliding door failure to open/close/latch
Driver or passenger sliding doors fail to open, close, or latch properly. Doors may open unexpectedly while driving, close only partially, refuse to close despite repeated button presses, or pop open after appearing closed. Some doors grind or make noise during operation. Defect occurs in both power and manual modes.
When: Varies from early ownership (15k–26k miles) to higher mileage (48k–113k miles); some failures occur within weeks of purchase or routine maintenance
Symptoms owners cite: Door opens unexpectedly while driving at highway speeds (45–55 mph); Door will not latch when manually closed; Door opens only partway before slamming shut; Door requires multiple button presses to close; Grinding noise during door operation; Popping sound when door fails to latch; Door gets stuck mid-travel and requires multiple attempts to close fully; High-pitched beeping noise when door is open; Door remains open when commanded to close
Codes mentioned: P1603
Repairs/costs cited: Toyota replaced upper door hinge ($323.46 out of warranty for one owner); dealer replaced entire motor assembly on another; some owners report 2.4 amp parasitic drain after failed recall repair; roller bearings found badly worn on one passenger-side door that came off track
Recalls/TSBs owners mention: NHTSA Safety Recall 16V-858000; recall parts were on chronic back-order for months/years, delaying repairs; Toyota denied reimbursement to at least one owner whose symptoms matched recall description; dealers refused repair on vehicles with aftermarket handicap seats installed, citing obstruction despite recall coverage promise of 'no charge' repairs
Door hinge rust and mechanical failure
Hinges on sliding doors rust out and fail structurally, causing doors to fall off the vehicle or cease operating. Occurs even on replaced doors and at relatively high mileage, suggesting durability issues with hinge design or material.
When: At 113,000 miles on one vehicle; hinges rusted despite vehicle always garaged
Symptoms owners cite: Door falls off vehicle; Hinges rusted out and non-functional; Door hinge breaks or separates from door
Repairs/costs cited: New hinge replacement cost quoted but not stated by owner; door detachment prevented diagnostic testing at a facility
Recalls/TSBs owners mention: No recall identified for hinge rust/failure; no manufacturer notification
Parasitic electrical drain from sliding door system
After recall repair, sliding door system draws continuous power even when doors are closed and vehicle is locked, draining battery and causing hard starting.
When: Occurred after recall repair completion
Symptoms owners cite: Hard starting as if battery was weak; 2.4 amp continuous parasitic draw at battery positive lead; Draw persists even when doors closed and vehicle locked
Repairs/costs cited: Detected via ammeter testing; issue emerged post-recall service
Recalls/TSBs owners mention: Recall 16V-858000 service performed; drain issue not addressed
Sliding door operation hazard—door slamming on occupant
Power closing mechanism malfunctions, slamming door shut on passenger (child) with finger caught inside. System falsely detects obstruction and fails to stop door appropriately.
When: During attempted entry after opening via keychain button
Symptoms owners cite: Door opens only halfway before slamming shut with force; Door latches with passenger's finger trapped inside; Door will not operate after incident
Repairs/costs cited: Door damage and safety hazard; repair status unknown
