Followup - the dealer checked with the OEM who said they don't consider it a manufacturing defect, but would cover the cost of the part and dropped the labor charge down so the total cost to me to a little under half of what they first quoted. Thanks for the assistance!

Yes, that would be a

Yes, I agree. Really, I think I'd remember some massive spill of caustic Coke, at most I'd think there would have been an instance or two of water/coffee that dripped or sloshed a little bit on there. Nothing that should have been able to leak through and gotten onto unprotected electronics.

They're the only dealer in Michigan, where I am. I had thought about calling one in another state to ask about the part cost. The car is fully under warranty except that they consider it customer damage and so not covered. I might ask another dealer how they treat water spill/infiltration...

Yes, agreed on the more uniform corrosion if it was precipitate from high humidity. I said the same thing to the dealer about sealing the board. Right next to the cup holders is the most likely spill area and if the radio knob shafts and edges of the module were not sealed, then why wouldn't...

More pics, sure thing. Here is the top of the module - a couple coaxial rotary knobs (function switch and volume pot), and a couple of micro-deflection switches. You can see a little water stain on the one switch, but again, how should that be able to get under the module and onto the downward...

Yes, this module is mounted in the center console between the vehicle seats with the side of the pcb facing downwardly so it is not clear how liquid would have gotten onto that side of the pcb from a spill, but that is what I am trying to determine. Could the corrosion be just from a couple...

I already ruled out aliens, but this module is mounted in the center console between the vehicle seats with the side of the pcb facing downwardly so it is not clear how liquid would have gotten onto that side of the pcb, or that the corrosion could be just from a couple instances of liquid...

This pcb came from a vehicle interior with the board side seen in the attachment facing downwardly with some space below it. It was installed inside the vehicle. The car is about 2 years old. Any idea what would have caused this corrosion on the transistor leads? The unit is not working and...
