My 2015 Leaf S that I purchased at the end of my lease appears to have dropped its first bar at 20,000 miles.
Weirdly, driving off fully charged displays 11 bars. After driving 5 miles or so, the 12th bar reappears.
Residential Driving: 90+ miles on the GOM. 85 miles or a little less in the real world. I never drive it much below 12-20 miles
Mixed Highway/Residential: 70 miles...maybe. Driving more than 60 mph appears to rapidly drain the battery. A round trip to Atlanta airport is about 63 miles from my home...mostly on the interstate...and I have avoided attempting it in the last 6 months. I don't even consider turning on the heater on that run.
Mind you, my Miles per KWh is always in the range 4.2 - 5.6
The tires are inflated to 41 lbs. and carefully monitored via Leaf Spy Pro. I have long supported the notion that tire inflation is probably one of the main factors in still getting the range I do despite the car being 4 years old. The Bridgestone tires are very worn on some edges.
As spring rolls through Georgia, I do notice my range increasing, if only a bit. But we only dip to 20-30F degrees a few times a year, so it's nothing like those of you living in cold climates.
