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)

Both of the cables on my power doors have snapped now. Turned off switch & have been doing doors manually. The rear passenger side one doesn't like to slide and doesn't open fully.

Leaking water into passenger side during rain. Many have reported the same issue. Seems to be some loose seals on the roof.

I just but this car but I think the seller changed the mileage on it.

Rear ac system the line is too close to the rear tire which was replaced once yet it is so close it gets friction and wears a hole in the line . Dangerous for people in the rear that may be inhaling a/c vapor while ac is running with a leak . Also bad for environment. There is no clearance the tire is almost right on the line so when you hit a bump you are rubbing it . Repair man says he has had to repair several lines more than once because of them being placed too close to the rear tire . Date below is third time this happened same vehicle. First was in 2016 second was 2018

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.

Sliding door does not open or close automatically. I think there was a recall for this issue

Driving down highway noticed white smoke coming from car. Exited highway and warning light then came on saying engine oil low. Stopped van immediately on side of the road and had it towed. Appears the oil coolant line burst which is a known issue on these vehicles after google searching, but was never made aware. Always completed all recalls. Extremely dangerous especially with children in car.

My passenger side sliding door began to jerk when closing with power button. The next day the cable completely snapped and it no longer opens at all. My driver side sliding door constantly opens and sometimes does not stay closed. I can hear the lock roll and it automatically unlocks itself. There was previously a recall on these doors completed I'm afraid I still have defective parts.

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

The intermediate shaft makes a clunking noise when turning the steering wheel.
