Millions of people could be stranded in the middle of nowhere if they do not know about this negligent design flaw. Toyota designed an rubber oil hose that gets stiff and breaks. This is design negligence to use rubber hoses on an oil system. Toyota redesigned this part with steel instead of rubber .this shows me they knew the design was bad in the first place. Van's ABS and vsc lights come on but no oil light warning. My motor started making noise but I didn't know it ran out of oil. There was no oil warning light. I didn't know it was the motor making noise. My car engine was completely out of oil. Again, no oil light warning. Since I found out about this, I found out about four more sienna's that had the same defective parts. Frankly all of these hoses will go bad as the mechanic remarked about this problem car engineers know exactly what they are doing when they design a car. I worked in manufacturing and engineering those parts are well documented when they are predicted to fail. One would consider two scenarios. 1.they had bad engineers designing this system, however car manufacturers know exactly what they are doing when they design a vehicle. 2.or they designed it to break to sell more replacement engines for four thousand dollars each. They kept this a secret or made no mention of this probably to sell engine replacements. The toyota manager called me and basically told me tough. Therefore I will be suing them in small claims court. Hopefully toyota will be replacing my motor. By the way I take very good care of my vehicles I maintain them with regular vehicle inspections along with oil changes at the prescribed mileage.

Steering knock is experienced at speeds of approximately 35mph and less whenever steering left or right. This condition was first noticed at approximately 80k miles and has gotten worse over the next 50k miles. The knock is not only felt in the steering wheel, but it has become an audible noise as well. I've read several complaints where dealers have fixed this known problem, however I haven't seen any recalls on this or any information from toyota stating that this is a known condition and is safe to continue operation. Until toyota acknowledges this as a known problem and determines whether or not it is a safety issue, then I'll continue to operate my 2012 sienna with the understanding that it is safe to operate and just put up with the knock. It would certainly be great if toyota would at least put its customer's mind at ease by at least making a statement about the condition and whether it is safe to continue operation of vehicles with this condition.

I have a 2013 toyota sienna and noticed a clicking/knocking sound whenever I'm turning the steering wheel to the left or right while in motion. I thought it was the cv boot and so I brought my car to two local shop mechanic but they could not find the issue. I have checked online and found something that might be the cause of this knocking sound. I saw in one toyota sienna forum talking about the issue with their "steering intermediate shaft" where one of the owner have this issue. The mileage of my van is 104900 just pass the warranty of 100k but still less than 5 years by april of this year. I know their warranty policy is which ever comes first. And I've noticed this issue 10 months before my mileage goes more than 100k but I did not pay attention on this because I thought it's gonna go away. I live in ontario canada.

We have 54k miles on our van and heard a knocking noise when we would make a turn (right or left). I brought to dealership and they said we needed to replace the intermediate steering shaft. The cost was $750. I looked online and see previous recalls for toyota for this same problem. I also searched and found several complaints about this same problem with newer year siennas like mine. This is obviously a defect that is still impacting toyota and consumers. Toyota was not willing to listen to our problem or help in any way.
