It never was a recall on 05+ trucks, just a limited service campaign. They did recall and/or buy-back some of the first gen trucks. A recall would actually give the owner some leverage. These LSCs are voluntary and experiences range from seamless to royal pains in the rear.
My extension to 12 year corrosion warranty is up this month so I'm now on my own. I have a sneaking suspicion this truck won't last the same 27 years as the one before it.
Just make sure you get the inspections they require because if it does rust through and you haven't jumped through every hoop they might use that to deny you.
