electrical shorts

My new Vectrix has an odd thing happening. When I'm driving at night. Well, I can't see the problem in the daylight, but what is happening is all the electronics/dash read-outs, surge up and down every 2 to 3 seconds, going from bright to dim, back and forth. No sounds, no relay clicks, I'm wondering if this is something that I've read that Vectrix had put a saltwater damage control on it to spike and clear the biuld-up on any device points and connections. Could this be it, or do you think it could be trouble.
