A complaint is an unverified account by the person who filed it, not a finding of fault. One complaint is one ODI number, which is how NHTSA counts them.

Complaints rose by half year on year: 15 in the twelve months to 2026-Q2, against 8 in the twelve before.

A recall is the manufacturer conceding a defect, and the repair is free. Whether one covers your particular car is a question only its VIN can answer, because a campaign covers a production range rather than a model year.

Red marks a system with a recall campaign against it. One complaint can name several systems, so these add up to more than 232.

When the complaints arrived

By the year NHTSA received them

By the year NHTSA received them, which is not the year the failures happened. They peaked in 2017 at 73.

80 60 40 20
15 16 17 18 19 20 21 22 23 24 25 26

This is the year the complaint was filed, not the year the failure happened. The range runs from 2015 to 2026, the last of them a part year, which is why its column is drawn faint.

Crash test ratings

NHTSA New Car Assessment Program

NHTSA crashes a car into a barrier and a pole and measures what happens to the dummies inside. This is what it awarded the 2015 Toyota SIENNA, and it is a separate question from what owners report going wrong later.

Test VAN AWD VAN FWD
Overall
Frontal crash
Frontal, driver
Frontal, passenger
Side crash
Side barrier
Side pole
Rollover

A rating belongs to a tested body style and drivetrain, not to the model as a whole, which is why more than one is listed. A dash means NHTSA did not rate that test for this vehicle.

ENGINE
Component Failed & Availability: The engine on my 2015 Toyota Sienna (99,000 miles) catastrophically failed and is completely seized. The vehicle and engine are in my possession and are fully available for physical inspection. Safety Risk: The vehicle shut down completely while in motion, causing an immediate loss of motive power, power steering, and power braking assistance. Had this un-warned seizure occurred at highway speeds rather than a parking lot, the sudden loss of vehicle control would have posed a severe crash hazard. Reproduced/Confirmed: Yes. A certified mechanic removed the serpentine belt, attempted to turn the engine with a lock bar, and confirmed the engine block is

ENGINE
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

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

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

If this is your car and a dealer keeps failing to fix it, your state's lemon law may require the manufacturer to replace it or buy it back. How many repair attempts it takes, and how long you have to file, is set by the state you bought in and by nothing on this page.

Where these numbers come from

A complaint is one owner's account and has not been verified by NHTSA or by us. A vehicle with more complaints is not necessarily worse: models that sold in larger numbers collect more of them. How this is counted.
