I suspected it was going to go for the last 2-3 weeks. All of a sudden starting about 3 weeks ago, my range on the GOM dropped about 10Km at full charge over the course of about 2 weeks.
I am a little alarmed that the range dropped so quickly. I did get new front tires about 5 weeks ago, and while they weren't the OEM tires (Michelin Primacy), I never noticed any loss in range despite all the doomsday scaremongers claiming massive decrease in range by not using the OEM tires. That was until about 2-3 weeks after purchasing them when the range started to decline.
Part of me is glad that the range loss is due to battery degradation and not the tires. Another part of me is pissed off my max range on the GOM is now ~120Km, and a realistic range of only 80-90Km, and yet another part of me is concerned at the rapid rate of degradation in a very small time period.

No dramas for me, ours still at two bars, & can get 120+kms on a full charge. Range per charge has a myriad of contributing factors. Our biggest energy sap is 110kmh freeway. So many factors involved in the energy used. Our quick calc is just under 100W/Km. Take it away from the hilly freeway herds speeds, and it easily pulls in excess of the GOM. I have tested the 11km reserve at the "screaming battery low", and now use the secret reserve in any distance calculations. Bear in mind the car couldn't suddenly drop its distance ability in line with the notch missing, it's more of a rough indication, and how very little it affects your driving. Keep on EV-ing. See how the mystical " gosh, it must have lost soooo much value" impacts real use. No different to yesterday with only one bar/notch missing. However!!!, if you get to, or below the 69%, and it has no real affect, keep driving. Register your warranty claim just before 100,000 or five years for full benefit. Btw, if you suddenly overnight have to sell....

I'm getting about 160w/km. Partly driving style, but also virtually zero flat roads around our area. I typically use about 35km of the GOM range on my 20KM drive to work.

On reflection, it's a little like cruise control, it can only work with the data it has. We find the GOM to be within 0.2km estimated against actual. Pretty impressive over an almost 60km return journey.
I sympathise with the developers on the GOM algorithms utilized, it has to be one of the most difficult parts of the car to do. Anything short of a crystal ball may not be good for all I guess. Still, it's an estimate based on a number of factors, not helped by the distinct lack of out-and-about charge points. Add into the mix a human, and there is a problem.
As long as it serves it's purpose, it's good.

I think they can improve the GOM. Having a Renault Zoe as well, same master company, thier GOM is awesome. If it says 115km to run, then that's pretty much it. It doesn't vary up and down each hill. A much better algorithm than the leaf. In saying that I prefer the leaf for comfort, noise and smooth ride.

Was there an improvement on the so called software update?. Ours hasn't been updated though.

Yes somewhat, no so much variation, lower overall range though.

Touch wood I'm still on the first bar lost after 59,000 kms. I charge everyday to 100% now where before the lost bar I was doing a lot of 80% charges. I don't care so much anymore so I just go to 100% every time now.

I'm also charging to 100% every time now. I figure if I cook the battery, I only have to deal with it till both my Model 3s get here, although that will hurt resale value a bit. There's also about a 20% chance I will be getting a Model S before the end of FY'17. When the Leaf gets sold, 4wardthinking gets first dibs.

I have always charged to 100%. I am more concerned about extreme air temperatures for both using and charging. We have had 40C here recently and are expecting it again in a few days time. I try not to use my LEAF in such heat and definitely don't charge then. I have battery back up for my solar panels and that cuts out at 40C. For me heat is definitely more important than how much charge I put in my battery.

Same here. Heat in excess is number one battery life reducer. When it's warm, and unless I I need greater 10%(100%), I keep to the lower charge. If the car is out of use, or I have no telemetry:(, I leave it at around 30% as it sits in the garage. I am missing telemetry.
