Here is a new one ... I have a 2006 FEH, last month wife was leaving a friends house, 1 minute later the car stopped and she told me the "red triangle" was displayed. Had the car towed by AAA home. After searching the web for "red triangle" car stopping ... one solution was to replace a bad fuel pump. That evening, I unscrewed access to the fuel pump, checked the electrical connections ... voila! The 4 contacts were corroded! Cleaned them off with contact cleaner and the car has been running fine for the past month. On other boards, owners had new hybrid battery installed ($$$), new MECS pump ($$), new fuel pump($). Clean the fuel pump contacts first ($0).
