Vehicle: 2011 Toyota Sienna XLE VIN: [XXX] Mileage: ~204,800 Incident Date: [XXX] Recent Service: Oil change, tire rotation, brake inspection, and multipoint inspection performed on November 10, 2025 at Fitzgerald Toyota Gaithersburg (Maryland). Description of the Defect: On [XXX] while driving with my child in the vehicle, my 2011 Toyota Sienna experienced a sudden and dangerous failure. A strong burning smell entered the cabin, the ABS warning light illuminated, and then wheels locked up while the vehicle was in motion. At the same time, the steering wheel locked, making the vehicle impossible to steer. The engine immediately lost power and shut down in the middle of the roadway. The vehicle would not restart and had to be towed. This failure occurred four days after dealership service at Fitzgerald Toyota Gaithersburg, which included an oil change, tire rotation, and brake inspection. The dealership initially claimed the failure was due to a “dead battery,” and the following day changed the explanation to a “shorted alternator.” A weak battery or alternator failure does not explain a mechanical wheel lock or steering wheel lock while driving. The dealership has refused to provide diagnostic documentation or photographs of the components involved. This incident presents a significant safety hazard, and if it had occurred at highway speeds, it could have resulted in a severe crash. I am reporting this to request investigation into a potential safety defect involving the steering system, braking/ABS system, electrical system, or related components. Safety Risk: High. Loss of steering control + wheel lock + engine shutdown presents an immediate crash hazard. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I was pulling my 2011 Toyota Siena into a parking space. My foot was on the brake and the car was going about 5 mph. The car made a slight sound, along with a perceptible yet small physical shift, and (while my foot was on the brake) independently accelerated with tremendous force. It was like it was ignited. The car hit a concrete pole and was totaled. The acceleration over-rode the brake. No one was hurt. The concrete pole averted what could have been a catastrophic accident, had we hit pedestrians, or had we rear ended a car or truck on the freeway. The brakes failed as the car jumped into independent acceleration. My safety and the safety of my passenger were both at risk. As I said, in a different situation, we might have hit pedestrians, or gone through the wall of the grocery store and hit customers. The concrete pole saved us and others. The mechanic at the service center where the car was towed said it was impossible to discern if there had been a failure in the system of the car - though clearly both my passenger and myself experienced that failure in the car's ability to override an independent, forceful acceleration not caused by the driver. There was no warning of any kind. On the Edmunds site, there are many, many testimonials by other drivers of the Toyota Siena of similar, frightening experiences of independent acceleration. It is terribly dangerous and should be investigated. If there is not a recall on this vehicle, there should be. This is a potentially catastrophic defect.

Power steering light came on while driving causing the steering system to lose power suddenly. Almost got into an accident because I couldn't effectively turn the wheel. Mechanic inspected and found the steering motor was bad and that CPU needed to be replaced costing almost $4000 in repairs. Now my car is not driveable unless this is fixed. Car has only 140k miles. This is a VERY common problem with Toyota Siennas around these model years

I have a Toyota Sienna 2011 XLE for 4 years and both doors stops randomly when opening and closing. My daughter was stuck in the car at least 10 times. She afraid to use the car because she repeatedly in danger of falling, the beep sound comes and the door stops suddenly. I used to drove my car leaving my door open once, because the door stuck and I couldn’t realize till I drove. I was lucky, my door didn't hit anyone or any car in the parking lot. The people were looking at my car with scary eyes. Obviously, It creates a safety risk for my family and the people around me. Because a lot of people have the same door problem, I informed Toyota. They responded, they have an extended coverage for the Power Sliding Door Cable Sub-Assembly but it’s expired on 09/16/2021. They know the problem and solved it temporarily without informing the owners and now they said, it’s over, you need to pay it. I am not asking for my seat covers replaced. It’s definitely a security issue, a suddenly stuck door can harm/kill passengers and people around. Toyota knows the problem but refuses to solve it. I don’t want to drive this car with knowing the risk of hurting anyone especially my 6 years old daughter. It’s so shame one of the biggest companies of the world produces risky cars and they continue to sell them with knowing. They shouldn’t risk the people in United States easily like that.
