2018 Nissan,

[ElTazz]

Own a 2018 Leaf, when driving 60 mph going uphill Battery will show rapid discharge, than going down hill it will return to the normal charge. Example: Will drive a distance of 10 miles, during the drive the Battery with fluctuante all the way down to 0% than back to 95%. At the end of the trip when the car is parked the car shows a battery reading of 90%. Any suggestions of what can be wrong. Thank for the help
