I agree, and even though your issue may be completely different reason mine did the same thing. Perfect for half of trip, then hit a rest stop or something and it would ding at me 10 times in 15 mins and then work for another couple hundred miles without issue. I could stop and plug/unplug and wiggle everything and not find a problem, plug it in drive 50 yds and get the ding and message.
I guess I don't 'really' know if it is fixed but I did see evidence of arcing on that connection and after replacing both plugs had zero issues on the last 500 mile round trip.
