Have been having on and off problems since new in 07. The four small gauges will go dead and I get brakes, ABS and battery lights. Was happening about twice a year now every trip. Have tried checking all connections and grounds to no avail. I know this has happened to others and wonder if there has been a fix identified. The engine runs fine it just seems to loose communication with part of the cluster.
Read that thread sometime ago. I have tried all of the fixes listed, but no go. Was hoping "bever" would read this and give an update. In researching this I have learned many have had the same symptoms, but either cured (it or think they cured it) via different fixes. This is a good one. The dealers (chev and jayco) point to each other as the root cause and neither can say how to fix it.
