No responses so I thought I would add these pictures

2013 C-Max eventuate goes down while driving. After just a few miles and the EV gauge gets near bottom and the car slows to 20 mph and get Stop Safely Now on dash. After sitting in park for a while, the EV guage goes back up. Then I can drive another mile or two until the EV gets to the bottom again. Do not know if coincidence but started soon after had the wiring harness replaced. Any suggestions how fix ?

Seems like the software engineers could have added software to reset numbers after they top out and use a dot or some other symbol beside the new numbers for each time the 999 had been reached. Then the mechanics would always know the true numbers.

2013 Ford C- Max CEV gauge goes down while driving. When it gets near the bottom a “Stop Safely Now” alarm comes on and the car slows way down. I can press the gas while parked and watch the CEV gauge go up. After most of the way up I can drive it a few more miles. This started about the time the wiring harness was replaced. Any Ideas. Thanks
