In addition, there were absolutely NO green bars on regen charge. The battery SOC meter showed almost full, so I guess it's understandable why there was no charging going on. Just don't know why MPG was so low.
This condition happened for the full two minutes I decended the hill. At the bottom, things seemed normal again. Still too cold for AutoStop, but everything else was fine.
Any idea why this happened?

I've also seen erratic behavior of the IFG sometimes. It will show very low mileage when it doesn't seem to make sense. It also bounces up and down sometimes for no apparent reason, when the engine is cold.
When the engine is cold it revs up on automatic choke, consuming a lot of fuel and not activating the valve shutoff when gliding. Still, I don't think that explains the occasional erratic behavior.
