What owners wrote
On-freeway gas engine/electric motor shut-down. Driving in morning rush-hour traffic approximately 15 minutes after cold start in 60-degree weather, both the gasoline engine and the electric motor propulsion systems shut-down together without prior warning while the vehicle was in motion - "stop safely now" was the `too-little-too-late' info on the instrument panel. Neither power mode would restart with trans in neutral (I refused to try cycling ignition key to off, and risk steering lock).
Driving in fast lane of freeway when "stop safely now" message with red alert came on. The engine stopped running. No warning, no ability to drive to the side of the road. This is a known fault in this vehicle. I cannot conceive of a problem that would require the engine to stop immediately. It is just luck that we got to the side of the road without incident as there was a lot of traffic, and without power, it was just plain luck that we managed to get to the side of the road.
