Engine Cooling System problems of the 2000 Toyota Sienna

I own a 2000 Toyota Sienna le. I noticed a coolant leak. I took it in to a Toyota dealer and discovered the problem was the leak from the cooling pipe. The cause of the problem was the cooling pipe was rubbing against the power steering line (according to the service advisor) and the cooling pipe wore out. I asked if it was a design flaw. He replied that he never saw this before, but there should be something between the cooling pipe and the power steering line to prevent the rubbing. This fix is $410 for parts and labor and is not cover under the extended warranty since it is a pipe that broke. I feel like this is a design flaw by Toyota.

I took my new van 6 times to 2 dealers to get the problem fixed but they could not. I filed a case with Toyota's arbitration program ncds (case#1200092) declaring my vehicle as a lemon and asking Toyota to repurchase the vehicle. Ncds denied my request on absurd grounds. Toyota claimed in defense that the vehicle is safe to drive contradicting the owner's mannual itself. The manual warns owner not to drive the vehicle under the conditions my vehicle was in to prevent personal injury and damage to the vehicle. After getting frustrated with ncds and my new $30,000 van out of service for more than 3 months, I finally had a third dealer fix the problem. American consumers do not have to compromise safety and undergo such a pain for manufacturer's or dealers' mistakes. No safety defect listed in summary.
