Mine drops that much when below freezing on a FLAT surface. On one hand, it's better than prior systems. On the other hand, it's still abysmally worse than conventional systems.

This is just one of the many risks of being an early adopter, I suppose.

I agree that once this major bottleneck is removed, the vehicle will be much more competitive - assuming the fix doesn't increase the cost too much.
