The 2015TOYOTASIENNA carries 281 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 21 crashes, 8 fires, 33 injuries, and 0 fatalities. For crash performance, NHTSA's New Car Assessment Program gave this cohort an overall 5/5 rating, with 4/5 front crash, 5/5 side crash, and 4/5 rollover scores derived from standardized barrier and dynamic tests.
Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2015 SIENNA is structure:body with 52 filings, followed by electrical system (41) and unknown or other (41). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability. This model year has 6 active recall campaigns, which means the manufacturer is obligated to remedy the covered defect at no charge for the life of the vehicle, the full NHTSA campaign numbers are listed below.
NHTSA currently has 51 investigation files overlapping the 2015 SIENNA, and 1 remain open. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page, a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

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 doorâs 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. Betwee

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 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 âNot Actualâ 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 didnât 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
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 driverâs 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.
Mileage: 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).
I have had this car for 7 years. Started having issues a year ago and despite bringing it to Toyota 2x, they cannot tell me what the issue is. I will be driving on a regular flat paved road when the car will suddenly brake and pull me towards the side of the road. I get the ABS code sometimes and also the slip indicator light. I've explained this each x I've brought it in and they have told me it's due to me "driving too fast" or "accidentally having my foot on the brake." LOL I am a typical soccer mom and drive conservatively and don't brake when I don't have to. It will do it on curving roads as well as straight roads. When this happens, it is terrifying! I have gone to different mechanics as well and no one can determine this issue. I've replaced the ABS sensors on this and am still having this issue. I don't know what else to do, as this is unsafe and unsafe to the extent that I no longer allow my 17 year old to drive it. Please help!!!!!!!!

Passenger sliding door jammed and would not open! Serious safety hazard as passengers unable to rapidly exit in an emergency!
Water intrusion from front sunroof when vehicle is parked at a 5% grade with the nose downward. Multiple vehicles exhibit this issue. Toyota is not creating any TSB and will mot even remedy it even if we have an extended warranty. Here is a link to the discussion thread: [XXX] I have not posted on this thread but I have the exact same issue for years. Toyota dealerships want me to first pay $1000 in labor to pull down the headliner and test. Then ask the warranty to cover the assembly, if they don't cover it... then I am on the hook for the work. The missing seam sealer is a common issue that will not manifest inside the 3yr / 36k mile warranty. My issue started around 2020 that I noticed and every dealership would not help me other than place a large burden on me. This can impact the electrical and the airbag curtains. The issue needs to have a seal sealer added to the sunroof assembly as the fix. As a family vehicle, this is a dangerous issue for multiple occupants in a single 7
