Question Asked: Is this another Toyota Sienna manufacturer defect?

You would think that Toyota would manufacture a vehicle to survive the Western PA winter condition. Not so! My Sienna is 3 years and 2 months old with 43K miles. The A/C tubing (exposed part in the rear and beneath the vehicle) is already corroded. Dealership blames it on road salt and is asking for > $1,350 to replace the tubings, with no guarantee that it would survive more than 2-3 years. I am a mechanical engineer myself and consider this to be a costly design flaw. There is a history of corrosion with Toyota vehicles. Unfortunately, it is not going to cause a recall like the corroded spare tire cables or the rusted frame in other Toyota vehicles. But what a shame! The dealership staff has great pride of the brand and wants happy customers, but the product just does not live up to its reputation!
