2013 Undercarriage Rust - Maybe I'm Paranoid
 

So I picked up my Durango from a dealer with 16,000 kms. It was a corporate vehicle and came with a clean Carfax/Carproof and paperwork showing it was a corporate car, not third party.


A few months later, I had it on the hoist at my mechanic's and noticed that the underbody looked a little surface rusty. My mechanic told me he'd seen the same before and we didn't see anything invasive.


Cut to a few months later and my AC dies. Dealer finds that my AC lines are corroded through and are replaced front to back (almost 16hrs of warranty work plus 3 days of a Dodge funded courtesy car). That's an issue that shouldn't present until well into the 100,000 kms ++ range. Dealer says, "You never know until it happens."


Now my paranoid thought:


Did the person who drove it before me decide to go beach surfing with their demo? Maybe they thought they could navigate a flooded road and had to ditch?


I know this would never be reported on a Carfax let alone disclosed by the seller. My worry is, if that were the case, what am I in for in the long haul?


Or maybe I'm just paranoid...

It really would take some serious exposure to salt or something else corrosive for that to happen

I would give the entire undercarriage a good bath, and some rust resistant spray paint that will seal and reverse those ares that way it is all stopped and corrected.
