2011 Toyota Sienna brakes problems

Filed Jul 9, 2026 · Brakes, Suspension · KY

The glide pins in the calipers came loose and one of the pins fell out (left front drivers side). As a result it caused the caliper to seize and smoke. It got hot and mangled the lower left control arm bushing. I bought a new glide pin and that one stayed it, but the right side (original part) came loose again, even after tightening it. We replaced the calipers with a different brand and it had no issues.

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)

Catalizador causando bajas emisiones, consecuencia encendido de codigos de luz de advertencia de tablero como luz indicadora de falla (check engine). Luz de advertencia ABS. Luz indicadora de derrape vsc-trac y luz de advertencia de presion de neumaticos. Al viajar por carretera simplemente se apago y sin poder tener control de la misma dicha falla causo que ya no encendiera al tener que solicitar grua para el arrarstre de la unidad hasta la agencia de toyota en cordoba veracruz. Seguro solo intervino con el arrastre de la unidad. Pero la sienna a llevado hasta el dia de hoy y fecha presente todos los servicios de agencia por la cual se llevo de inmediato, pero con la novedad es que ni la misma agencia le a podido quitar la falla. No tienen ni la menor idea de la causa. Su solucion seguen ellos eran los inyectores pero la camioneta volivio a hacer la misma falla y la agencia no da garantia de su mano de obra. Solo aumenta el gasto en refacciones sin solucionar la falla.

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.

The brake pedal assembly fell off while driving. Due to this the driver was unable to stop the car by applying brakes. The driver let the car slow down by itself a little before applying parking brakes to bring the car to a complete halt. In this process, the driver crossed three set of lights, which were fortunately green. Two of the lights were school-crossings. The safety of pedestrians, other cars on the road and the driver themselves were at risk. It was purely by chance that they were able to stop the car before any collision. The van is now at a repair shop. The experts at the repair shop said this is NOT normal. They have asked to raise a complaint to ensure that Toyota checks out the possibility of this occurring in other vehicles of the same model / year. There were no warnings before this incident happened.

We were visiting niagara falls this week and when we got off the exit my wife had no brakes. So we had it towed to a triple a repair shop and was told our brake line failed because it was corroded and was a cheap non oem brake line. We had to stay an extra night at our hotel. We bought it almost a year ago with 36000 miles and now has 43000 on it, I feel that braunability which did the handicap conversion should have used a oem brake line when the replaced it. I have als but my wife's number is (xxxxx) or email me back. We have a piece of the defective brake line thanks (xxxxx) parts of this document have been redacted to protect personally identifiable information pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6)

This is the fifth time I have problems with the brakes. I bought this car new. At 7000 miles, when I hit the pedal, steering wheel and car shakes and vibrate. Took it to the dealer, cut rotors, ok. At about 15000 miles same problem. They cut the rotors. Again, about 22000, same problem and now I had to paid because warranty expired,3 years. I wrote to the toyota, explain the problem and thy decided to refunded me the money I paid,$500. Now, about 32000 miles I had the same problem and I bought the best rotors on the internet with holes, because they said it was the heat. I paid a mechanic to installed them. Work fine for a while, but at about 40000 miles the car star shaking when I hit the brakes. I bought new rotors at an auto part and replaced the rotors again. Now my car have 48800 miles and I have the same problem. I took it to the dealer today and they still says is the heat that worn the rotors. I had so many cars in my life and I never had to replaced the rotors that often. I believed there is a factory defect in this car that cause this problems with the brake. Toyota don't want to investigate. I beg you to investigate and make toyota to look deeper in this problem. I don't buy the heat cause. This is not normal on a new car. It cost me almost $55,000. I don't think is fair. I think I'm going to take legal action against toyota and sue them. But first, I'm looking for your help. I have all the receipts for the 5 times I fix the car. I also saved the original rotors and the second ones I bought. The third rotors are still on the car.
