Every Warning light on the dash goes on, why ?

[Greg Herman]

New Outback. Had this happen several times. Every warning light on the dash goes on as I am driving down the road. RAB, Oil, all of them.Even the Collision Warning light. WHY? No other cars around, not changing lanes, clear weather, no reason for it. I already know the dealer will do absolutely nothing to help, they never have been any help. All they know how to do is delete the history, "destroy the evidence" but refuse to fix anything.
