Owner reports
Selected complaints filed with NHTSA by 2014 Toyota Sienna owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2014 Toyota Sienna. The contact stated that while driving 70 MPH, there was an audible alarm coming from the vehicle, alerting the contact that the door was ajar. The passenger's side slide door opened independently while the vehicle was in motion. The vehicle was modified to accommodate a ramp for the contact's two wheel-bound children. The contact pulled over to the side of the road and closed the sliding door. The contact's husband tied the door to prevent it from opening independently again. The check engine warning light was intermittently illuminated. The vehicle was taken to the dealer, where it was inspected. The contact was informed that two latches had corroded and needed to be replaced. The vehicle was not repaired. Upon further investigation, the contact related the failure to NHTSA Campaign Number: 16V858000 (STRUCTURE). However, the VIN was not included. …
The contact owns a 2014 Toyota Sienna. The contact stated while driving at various speeds, the contact heard abnormal sounds coming from the vehicle. The passenger's side slide door became inoperable. No warning light was illuminated. The vehicle had not been diagnosed or repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure and advised the contact to call the NHTSA Hotline for assistance. The failure mileage was approximately 68,000.
The passenger-side power sliding door system failed to stop or reverse when it encountered physical interference with the vehicle's open fuel door. The door continued opening under power despite clear obstruction by a fixed exterior body component. The affected components, including the sliding door mechanism and damaged fuel door latch, remain available for inspection upon request. A powered sliding door continuing to operate against an obstruction creates a foreseeable risk of injury to occupants or bystanders, as well as vehicle damage. If a person's hand, arm, or clothing had been in the same position as the fuel door, injury could have occurred. The incident occurred during normal vehicle use and demonstrates inadequate safeguards against obstruction. …
Fuel door hinge broke because the fuel door pin has so much tension that it broke the hinge. This caused a safety issue because the door cannot be opened from the inside if it is not closed all they way or pushed closed enough for the sensor to allow the sliding door to open. This event was reported past the 36 month warranty, (at 40 months, but less than the mileage warranty), but had begun before the warranty had ended. Current owners should be aware that if there are instances beginning of the door not being able to be opened, should check the hinge and pin tension and have it fixed while it could be under warranty. This should be an item covered under an extended warranty due to the safety issue of not being able to exit the vehicle in an emergency situation. This happened several times while parked and exiting the vehicle. Currently getting an estimate from the dealership. …
Recently, at approximately 80,000 miles, the upper hinge of the fuel filler door (the door covering the gas tank access) failed. This appears to have been caused by pressure exerted on the door by the safety switch governing the driver side sliding passenger door. This is a known issue, documented here: http://www.siennachat.com/forum/67-problems-maintenance-repair-gen-3/19274-fuel-filler-door-hinge-broke-anyone-else-have-happen.html#. I brought my van to my local dealer repair facility, novato Toyota, at approximately 81,000 miles and was told that the cost to repair would be around $380. I was told that neither Toyota nor the company providing my extended warranty would cover it. In addition to being caused by a mechanical design defect that could not have been foreseen, it causes a safety issue, as it will prevent opening of the rear passenger door when the switch is activated. …
This complaint is in reference to NHTSA campaign id 08V244000. The power rear liftgate struts on my 2004 Toyota Sienna will no longer support the gate, and it has closed on someone standing underneath it several times. I went to a Toyota dealer to repair the problem, and the dealer quoted a very high repair price (approximately $500), and did not mention that there was a service campaign for this issue. I contacted Toyota on March 19, 2015 using the toll free number listed in the service campaign listed on the NHTSA campaign id number. Toyota informed me that this was not a recall situation, but a voluntary Toyota service campaign, and that the period for the free repair ended in 2010. There is no end date for the service campaign listed in the NHTSA campaign notes. …
Side sliding door assembly rusted. Bought van in nov 2013 and by July 5, 2015, about 18 months, sliding door assembly is rusted (see pictures 1-3) - reported this to Toyota dealer when reporting sliding door closure issues during summer \ fall 2015. Van is parked in garage when not at work so it does not sit out in the elements 24/7, just outside 8-9 hours Monday through Friday. In 2015, Toyota dealer said they would not do anything so I sprayed wd-40 onto surface in attempt to keep from further rusting. Attached is a picture #4 of same door assembly from today (October 30, 2017). We have not had van 4 years yet, about 66,000 miles, and this component continues to rust. If door assembly fails, door could close on person by itself causing injury especially if vehicle is parked on hill.

Closed driver sliding door with inside button. Went into grocery store. Came back out and sliding door was wide open. Tried to shut door with fob and it gets about 3/4 closed, stops, then opens again. Had to shut manually. Took car to Toyota motorcars in mayfield heights, ohio. While parked in the service department, service advisor george madison tried to close it three times with same result. He had a technician look at it. Says door works fine for technician so there is nothing he can do. George, a Toyota service advisor, witnessed the door fail but would not even try to find out what is wrong. I am still under manufacturer warranty. Toyota's Sienna sliding doors are well-known to have problems.
Both sliding doors do not close. Have to push hard on the doors to close. Problem started with both doors at the same time, and after the factory recall work was completed six months ago. Dealer wants to charge $862 to fix both doors. Tail gate door comes crashing down. Serious injury hazard when children are close to the door. Dealer wants to charge $490 to fix tail gate door. Problem with tail door started three weeks after sliding door problem started. Field complaint with Toyota. Door operation is a significant safety problem that Toyota should address immediately. Opening and closing doors are with the vehicle stationary.
