2008 Toyota Sienna Minivan CE 8-Passenger 4dr Minivan (3.5L 6cyl 5A)
AC line corrosion
 Love this van, like the design much better than the new one....but....we had our AC line replaced under warranty last summer, this summer we find that 3 other lines are also needing replacement due to corrosion...Toyota and the dealers offered us 50% shared cost for repairs, but, this should not be happening. The cost to us is still $1900.00, and, we are wondering if this will be an annual cost to keep the air in our vehicle?Toyota Canada stated this is not an issue with the Sienna and there is no recall or fix for this issue...
