I’ve been having a regular issue with the energy recovery system where the engine picture greys out randomly (as seen in the picture) and does not come back on again. Every time this happens my MPG goes through the floor (20 MPG or less), the engine is lumpy and the i-Loop does not recharge - no matter how you drive - for the duration of the time the engine imagine is not illuminated. This even happens when the i-Loop shows full charge so I'm at a loss as to what the cause could be. Has anyone else known this issue or whether there is a fix to prevent it happening?
