You've posted saying you got a GOM of 108km which I would consider a problem, but then you just posted that you got a GOM of 134km which could be reasonable if you are driving at high speed on the highway.
The Soul has great room inside, all my coworkers love it when we take it for lunch, but it is an unaerodynamic box. Drag squares with speed, and power required cubes with speed https://en.wikipedia.org/wiki/Drag_(physics
If you are regularly driving over 80kph and are getting a GOM of 134km then that's reasonable. If you are only getting a GOM of 108km or are always driving at less than 80kph then I think you have a battery problem.
