Owners have filed 293 complaints
about the 2015 Toyota Sienna with NHTSA between 2015 and 2026.
The largest single group is the body & structure.
Across this model's run it ranks 5 of 23 worst.
The letter says how bad. This says what kind — whether this year drew
an unusual number of complaints, unusually dangerous
ones, or failures that arrived unusually early.
The dashed ring is 50 — the national norm. Further out is worse.
Complaint volume — 31
Against the median year of the Toyota Sienna. 50 means typical for this
model; 100 means roughly double.
Severity — 85
16.4% of these complaints
involved a crash, fire, injury or death, against a national rate of
9.7%.
Early failure — 100
59% of failures with a mileage on record happened under
36,000 miles, against a national rate of
29%.
NHTSA files every complaint against a named sub-assembly, not just a
system. This is the difference between knowing it was "the engine" and
knowing which part of it — the list to hand a mechanic.

Recalls on the 2015 Toyota Sienna
A complaint is one owner's allegation. A recall is the point at which
the manufacturer or a regulator agreed the defect is real and dangerous
enough to fix for free — however old the car is.

Recall 202172355,683 units in Canada
Electrical
Issue: This recall is for certain block heater kits installed on certain vehicles or sold as accessories at Toyota or Lexus dealerships. On certain vehicles, the engine block heater cable may not have enough heat protection and could be damaged by high temperatures. If this happens, the cable could short circuit while plugged in, and cause the wiring to overheat or melt. Note: This recall only affects the following block heater/cord part numbers: C014003034 PK5A408J09 PU14000904 C014003151 PK5A408J13 PU14000905 C014000885 PK5A489J11 PU14000907 C014000888 PK5A489J22 PU14000909 C014000907 PK5A410H00 PU14000911 C014100904 PU14000900 PU14000913 C014100907 PU14000901 PU14003571 C014100911 PU14000902 PK5A489J14 PK5A408J05 PU14000903 Safety Risk: Engine block heater wiring that overheats or melts could create the risk of a fire. Corrective Actions: Toyota recommends that you should stop using the engine block heater immediately. Toyota will notify owners by mail and instruct you to take your vehicle to a dealer to disable the engine block heater. For some vehicles, the corrective actions for this recall are under development. For others, a new engine block heater cannot be installed, and the owner will receive a refund of the purchase price of the engine block heater.
Recall 201931725 units in Canada
Brakes
Issue: On certain vans converted to a rear-entry mobility vehicle by BraunAbility, the fittings for the brake line extensions may be incorrect. This could cause a brake fluid leak that may result in reducing braking. Note: This problem affects conversions that were built between January 9, 2018, and May 20, 2019. Safety Risk: Reduced braking could cause extended stopping distances and increase the risk of a crash. Corrective Actions: The company will notify owners by mail and instruct them to take their vehicle to a BraunAbility dealer to inspect the brake line connections. If necessary, an adapter fitting will be installed and the brake system will be bled.
Recall 201658660,190 units in Canada
Structure
On certain vehicles equipped with power sliding doors, under certain conditions which impede the opening of the door (such as if the door becomes frozen with ice), the sliding door motor could stall when the door is operated. If the motor stalls, high current in the door motor circuit could be generated, operating the circuit protection for the door motor. If this occurs with the sliding door latch mechanism in an unlatched position, the door could open while driving, increasing the risk of injury to a vehicle occupant. Correction: Dealers will replace the existing junction block and the rear sliding door wire harnesses with newly designed ones. The dealer will also install two sub wire harnesses to connect the junction block to the two rear door wire harnesses.
Recall 20145362,027 units in Canada
Structure
On certain vehicles, in the event of a collision that warrants a deployment of the curtain shield airbag (CSA), the force transmitted to the headliner as the airbag inflates may cause the left and/or right side second row overhead assist grip to detach from its mounting brackets if the temperature in the roof rail area is high from outside ambient temperature. If an assist grip were to completely detach, it could contact an occupant, which would increase the risk of injury in the event of a crash. Correction: Dealers will modify the headliner near the second row overhead assist grips.

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.

We got into an accident today, and none of the sliding doors would not slide open. It would not even allow us to pull the doors opens. The vehicles electrical was damaged, but that should not prevent the other doors from opening. This is a very bad situation if someone is needing to evacuate the vehicle. The rear passengers would be trapped. Please address this issue with Toyota asap. People who usually have Vans have big families and small children. This would be a very bad situation if vehicle needed to be evacuated asap. The rear passengers would be stuck.

I am submitting this complaint to request that the National Highway Traffic Safety Administration (NHTSA) document and evaluate what may be a broader defect affecting certain Toyota Sienna vehicles and determine whether it presents a potential safety-related defect trend. My 2015 Toyota Sienna was diagnosed by an authorized Toyota dealership with an external rear-bank head gasket leak. A head gasket is a critical engine component, and failure can result in coolant loss, engine overheating, reduced engine performance, stalling, or complete vehicle disablement. These conditions may create a safety risk, particularly if they occur while driving in traffic or at highway speeds. An authorized Toyota dealership confirmed the diagnosis and submitted a goodwill assistance request to Toyota. The dealership noted my history as a repeat Toyota customer and recommended that assistance be provided. Toyota denied the goodwill request based on the vehicle's age and mileage. I subsequently appealed through Toyota's customer relations process, and the denial was upheld. I understand that NHTSA does not resolve individual warranty or customer-assistance disputes. My purpose in submitting this complaint is to request that NHTSA determine whether similar reports exist involving premature head gasket failures in this model year or related vehicles and, if warranted, evaluate whether a broader defect trend exists that could present a safety concern. Potential safety consequences include engine overheating, loss of power, stalling, and unexpected vehicle disablement. The vehicle has been maintained in accordance with manufacturer recommendations and has not experienced any overheating event that would reasonably explain a premature head gasket failure. Thank you for your consideration and for documenting this complaint as part of NHTSA's review of potential vehicle safety issues. Respectfully, Vehicle Owner

TIRES
I have requested urgent warranty evaluation regarding two Kumho Solus TA51a tires installed on my Toyota Sienna (Model: Kumho Solus TA51a, Size: 235/60R17 102H, DOT: 1824) Both front tires are exhibiting abnormal tread chunking and visible surface shredding. The tires are relatively new (purchased about 1-1.5 years ago) and have not been heavily used (only riding this car occassionally, about 5000-7000 miles per year). Our 2 rear tires are Kumho tires of different model, and although older, they are performing fine and do not experience these issues so it seems to be an issue on this particular Solus TA 51a model Kumho tires. Because this is our family vehicle and we transport our children in it regularly, we are very concerned about the safety of continuing to drive on these tires. I also returned to the tire shop that sold and installed the tires. After inspecting them, the owner advised me to contact Kumho for a warranty evaluation, informing me that he received similar complaints from other customers (especially Toyota Sienna owners) using this tire model. While I no longer have the original purchase receipt, the dealer can verify that the tires were purchased from and installed by his shop. I reached out to Kumho Tires USA by completing their online contact form 2 wks ago, which informed a response within 48 hours, but I have not received any response. I called and left a voice message in their warranty department, and in their general customer service line earlier this week, but still not response. I even completed another contact form and also reached out by email, but still no response. Then I remembered my mom recently sharing a concern about her tires, and just found out that she had same 'chunking' issues on her tires, which happened to be the same Kumho Solus TA51a tires from the same tire shop. Her car is Toyota Camry, not a Sienna, so this is happening on this specific tire model across all types of cars they are installed to. Please help!

STEERING
My 2015 Toyota Sienna has “Sticky” steering. When on a curve, like an highway curved ramp, the steering locks in place. I have to pull the steering wheel back to keep the car on track. When it sticks I can literally let go on a curve and it will hold it’s position. Even when driving straight this occurs. The steering wheel will stick in place requiring me to turn it to get the steering wheel to come back to the desired or correct position. I’m seeing that this is a regular problem for Toyota steering across multiple models. Having your steering get stuck in place has the potential to be a very serious safety issue. This may cause an accident and resulting death. The complete repair for this safety issue to the consumer is over $3000.00. This is ridiculous! This is my first Toyota. I think their reliability night be really over rated.

Manufacture initiated an investigation after we contacted their customer care line. Our vehicle was taken to a Toyota dealership on March 11, 2026. We received an email on April 13, 2026 stating Toyota's inspection did not identify any evidence that this incident was a result of a concern with the operation of our vehicles gear shift lever. We retrieved our vehicle from the dealership on April 20, 2026. On April 21, 2026 From our driveway the shift lever fell out of park into drive with the ignition off, no keys, and the brake pedal not pressed. Toyota claims no responsibility! How is this possible when they know there are active recalls for the same issue on earlier models? This is a massive public safety risk considering the vehicle can rollaway without the ignition even being on! I will continue to report this issue every time the shift lever falls out of park until resolved.

STEERING
The power steering has a notch or almost a stickiness when turning. In turns around interstate ramps the steering almost locks in place requiring physical effort to get the steering to straighten back out. Even driving in a straight line one can feel this notch like feeling where the steering wheel is not operating in a smooth manner. This gives me a serious concern over the safety of driving this vehicle. In researching this specific issue it is notable that Toyota issued a large scale recall on other models for steering issues exactly as I’m experiencing on my vehicle. It appears this overall safety concern extends beyond the vehicles listed in Toyota’s original power steering safety issue recall.

STRUCTURE:BODY
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.

NHTSA complaint #11692382 — an unverified report by a vehicle owner.
Bellevue, NECrash
POWER TRAIN
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.

STRUCTURE:BODY
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.

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).

ELECTRICAL SYSTEM
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!!!!!!!!
