2011 Toyota Sienna: brake failure

Filed Jul 29, 2024 · Acceleration, Body · TX · crash

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.

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)

My second complaint to the federal safety agency - previous the federal safety agency # 10470305 this is the 3rd time in 2 years I have had issues with the brakes when I apply brakes, the pedal goes all the way to the floor and vehicle doesn't stop. I have requested my money back or replaced my current sienna with a new one as I have previously asked for when it happened in may of 2011 after driving 600 miles on a brand new vehicle and at around 20000 miles in 2012 when it happened again. I fear for the safety of my kids, my family, myself and others around me when I am driving. Toyota knows they are at fault yet they want me to take responsibility.toyota refuses to help, they want to be given chances to fix it as they've tried twice already see previous complaint - I bought a brand new 2011 toyota sienna xle in may of 2011 from jay wolfe toyota in kansas city mo. After 1000 miles within less than a month, started having brake problems. When I press the brake, it was gliding, taking the paddle to the floor in order to stop the vehicle even at slow speeds. I was enroute to omaha for the weekend with my family and kids when I started having the brake problem. I took the vehicle back to the dealership and they took 4 days to check and determine it was air in the brake system. I am sure there was more to it but that is all they said and fixed. One person from corporate was there and told us and guaranteed that we should never see this problem again. Now less than a year after at 26000 miles started having same issues with brake. Now the dealership says there may be a leak in the brake system that may not have been look at before. I advised them due to safety of my family and my kids and others on the road, I am not taking this vehicle back and I requested to be replaced with another new vehicle since they are at fault by selling me a vehicle with a brake problem and by not fixing it right in the first place.

On dec.5, 2012 we were picking up a grandchild at an elementary school. We were in a line of cars to exit the parking lot. A car was pulling into the line ahead of us. We tried to stop to let her in, but there were no brakes. There was plenty of space and time to stop. We stopped by hitting her car. Our van had minimal damage, but she had a fender and passenger door damage. (we were thankful no children were injured as there were many around.) we had the car towed to j pauley toyota in fort smith, as we were afraid to drive it. They pronounced it safe to drive. We called toyota (800‑331‑4331) to have the black box checked as suggested. Still afraid to drive it we left it there and traded for a new van (honda). (see accident report for 2009 toyota sienna van VIN# [xxx]. First time we thought it was probably a fluke. Second time a problem with the siennas.) information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).

Noting that toyota have had problems with many cars with brake failure in the past. Please advise me what I would need to do in order to get my vehicle replaced for the safety of my family and kids since I no longer feel safe being in the current vehicle. Thank you,
