No less than 6 times in approximately 8000 miles the vehicle has lost all electrical power while driving and then regained power. All interior electric components are lost, power steering, headlights, everything. Twice it has completely stalled out when this has happened. I cannot recreate the issue on-demand. On occasion, the vehicle will not hold a hill. It will drift backwards when taking your foot off the brake. Again, this is not reproducible and is completely random.
