2015 TOYOTA SIENNA Complaints

The contact owns a 2015 Toyota Sienna. The contact stated that while the vehicle was parked, and the shifter lever was turned off, it unexpectedly fell down, causing the vehicle to shift into drive and roll down the street, where it crashed into a house. At the time of the incident, the vehicle was occupied by one three-year-old and two six-year-old children. One of the six-year-old occupants attempted to move the shifter into park while another attempted to steer the vehicle. The passenger-side sliding door was ajar. There were no warning lights illuminated. There were no reported injuries, fire, or airbag deployment. A police report was filed. The vehicle was taken to a local dealer; however, the failure was not diagnosed or repaired. The manufacturer was contacted, but declined the claim. The failure mileage was approximately 119,274.

Odometer Fraud. The contact purchased a 2015 Toyota Sienna. The vehicle was a private sale. The contact stated that at the time of purchase, the mileage was 92,862. The contact later purchased a Carfax Report which indicated that the last odometer report in 2024 showed that the mileage was 205,000. The seller was made aware of the mileage discrepancy.

In August 2025, AutoNation Toyota on Sahara, checked the VIN of my Toyota Sienna and contacted Toyota while I was present. Toyota confirmed a broken fuel-door hinge was covered under a Customer Support Program. Instead, AutoNation attempted to repair, rather than replace, the hinge. This caused the metal fuel cap door to end up bent, paint to be gouged out from the bottom of the fuel door area, misalignment of the fuel door, and therefore issues with the door’s sensor reading correctly. I took the van back until they received shipment of a new fuel cap door. After the attempted repair, since the fuel door no longer aligned, the safety sensors repeatedly activated which strained the sliding-door ECU. The passenger sliding door began freezing intermittently, forcing my children to exit through the trunk several times. Finally, the door opened on its own as I was driving down the street. These issues did not exist prior to dealership service and presented a clear safety concern. Between October and December, I received conflicting explanations from Gerald, James, Ivan, and Rudy at AutoNation Toyota regarding whether the issue involved the fuel door, ECU, motor, or general wear and tear. AutoNation repeatedly failed to return my calls or respond to the emails I sent them. Toyota Corporate also informed me the dealership was also not responding to their outreach attempts after I contacted them due to not being able to get ahold of AutoNation Toyota. I emailed four managers on October 15 with detailed documentation and received no response. My vehicle remains unsafe, unrepaired, and in the possession of AutoNation Toyota. I approve allowing it to be inspected. While at AutoNation, the vehicle driver could not open the passenger sliding door after AutoNation's attempted repair. They have had my van for 4 months now so no one else has looked at or inspected it. There were no warning lamps, messages or other symptoms of the problem prior to the failure.

Odometer Fraud. The contact purchased a 2015 Toyota Sienna. The vehicle was purchased from a private seller. The contact stated that while registering the vehicle at the local Department of Motor Vehicles, the contact was informed that the odometer mileage was last recorded at 141,000. The contact later purchased a Carfax report, which indicated the past mileage recorded at 287,000. The contact stated that when the vehicle was purchased on November 8, 2025, the odometer was recorded at 98,043. In addition, the mileage recorded on the title was 97,043, and in parentheses, the words “Not Actual” were handwritten.

My husband parked our minivan and came in to pick up the kids. While he was inside the library, the van went out of park and hit a fire truck in the parking lot. It seems this has been an issue with Toyota siennas in the past but I do not see it reported yet for its year 2015. Our van had damage to the front fender, hood, and surrounding area and needed repair. We obviously didn’t have any idea this was possible nor noticed anything since purchasing this van recently. I have read online that a Toyota sienna cannot be turned off without being in park. Since my husband was not in the vehicle when it crashed in the parking lot, it is clearly a defect of the vehicle.

Fuel filler door upper hinge failed so that door would not seat properly when closed. Because the door was not seated properly, the left side power sliding door interlock did not release, preventing the sliding door from opening fully. I had visited a fast food restaurant in Feb 2025 and ordered some French fries for my[XXX], strapped into his child seat directly behind the driver. He was choking on a fry, starting to turn blue. I quickly stopped and attempted to open the sliding power door, but it would not open fully to allow access to my grandson because the failing fuel door wouldn't release the power door interlock. By the time I ran around to the passenger side to reach him he had nearly passed out, but I reached him in time to extract him from the seat and performed a Heimlich to expel the fry and restore his breathing. Toyota should be forced to extend the extended warranty for the full duration of the court agreement of 10yr, Dec 2025, regardless of purchase date. My request for fuel door replacement in Jul 2025 was refused because Toyota claimed the warranty was only good until 10yr after date of purchase, not to the end of 2025. The warranty period applies to vehicles purchased Dec 2025, so the warranty program still exists, but Toyota National refuses to honor it for my vehicle. The inoperable power door can cause passengers to be trapped from quick exit in case of other emergencies, such as vehicle fire or accident rollover. Toyota should honor the warranty or risk legal liability for a death due to manufacturer defect! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2015 Toyota Sienna. While the vehicle was parked, the contact discovered that the fuel lid door hinge had fractured, causing the fuel lid to intermittently fail to open or close as needed. The contact stated that with the fuel lid intermittently inoperative, the rear driver’s side door failed to open when needed. No warning lights were illuminated. The vehicle was taken to an independent mechanic where it was determined that the fuel lid door and hinge needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 117,000.

My engine caught on fire. We had seconds to get out prior to it engulfing in flames. Fire department had to extinguish. Not sure what caused it. The entire vehicle caught on fire. There was an engine light warning I had the vehicle repaired but the warning light was not cleared

The slide door latch stopped working. The sliding door doesn't latch properly and I have to manually close the door and lock it to know it's secure. If it's not locked a slight push will cause it to pop open. My mechanic said there is a recall associated with the replacement part. I can't find the recall. However, I did find a related TSB (TSB-0244-17).
