Used to have to watch out for "flood"
vehicles in this region.
Mainly from the Houston area.
When they get one of those big storm
surges, that brackish GOM water floods
a good many new vehicles sitting on the
lots, and soaks up inside everything.
The body is somewhat compromised, but
mainly the wiring and the electrical components
get that brine saturated inside.
Most are dried out and "saved", but in years
to come the corrosion will leach up the
wiring and start causing nearly undiagnosable
problems, some relatively minor, some really
head scratching and stroke inducing.
I've seen wiring harnesses with green corrosion
from one plug-in to all the others just green
green green with corrosion. There's no cheap
fix. If the insurance covers it at all, it'll
most likely total.
Just about the only way to tell the story
is way up under the dash, and removing
the interior finish panels to look for a
high water dirt line. Nothing else causes
that except if the vehicle has been
soaked in flood water. New vehicle warranty
doesn't cover any of that, and the warranty
will most likely be voided.
