Why does Dodge go cheap with their steel?

What's the corrosion warranty?
Doesn't matter what the warranty says. Everything with Dodge is a fight. Paid roughly $3000 for the "lifetime" warranty on my wife's Challenger. That POS is growing roots in my garage. Someday the lawyers will figure it out. Until then they've got my $50k. GM will just about buy me dinner for a squeek or rattle.
