Has anyone had issues with a High Voltage message. My dash has gone out 3 times and the dash lights up like a Christmas tree. It has always happened when driving through heavy rain. We have the lithium package. Had it to Freightliner twice and they say everything checks out. The faults go away once I stop and restart the coach. The headlights have blown twice. I am hoping this isn't an issue that really affects me when the warranty is up in October.
