Harley Guy, Lormax, Fab.....1 of you most likely knows, I've read the issue about the early vin cars and the rdm's failing. My question is, is it an absolute certainty the RDM's will fail in early vin # cars or are you just saying the likelihood is higher if it was an early build car? I only have 2,800 miles on my car, #426, and it runs perfectly, no strange sounds coming from the rear.....yet! I was at least fortunate to have my battery replaced early on and had a Fisker Engineer to fly in to load the cars last update, have had ZERO issues since then, but don't think the RDM's were changed to my knowledge. Thanks a lot.
