When I get in my truck on a hot day, the A/C smells terrible when it is first turned on. It has a strong vinegar-like smell. Any ideas? The truck is almost new!

I get that too.

Is it a strong musty smell?

The condensate drain is probably plugged and not draining properly. When the water sits it gets kind of funky smelling. It'll have to be cleaned out and washed with some bleach to kill the mold, etc. Let the dealer do it.
