Twenty Three Months in Our Nissan LEAF
2013 LEAF SL in Black
Just a brief post this month. We continue to love the LEAF and it is still highly reliable, performing perfectly without any reliability issues and it continues to be our family's primary car.
One piece of news is that our electric bill for February came in at only $10.89 and our total bill for the net metering year is a credit balance, meaning that our "true-up" for the net metering year is a bill of zero for the entire year for all of our electric power use. This is the second year in a row that our annual bill has been essentially zero, meaning that our fuel bill for over 21,000 miles of driving our LEAF has been zero. Of course, this is due to our 5,160 Watt solar power plant on our home's roof and charging our LEAF after midnight using our utility's Time of Use rates for electric car charging.
Another event was our year-two battery check. Nissan requires an annual check on the battery pack to keep the warranty in effect, and the first two years' checks are free, as long as they are done close to the car's anniversary date. Our LEAF's battery got all five stars on all four parameters of charging, driving and storage history. So I guess we are treating our battery pack well. We still have all twelve battery capacity bars, which isn't true of all LEAFs the age of our car in Southern California, and we probably won't have all twelve bars after the coming summer's heat.
We also had the small twelve Volt battery checked, and it passed with a voltage of 12.41 Volts. This small battery is fully warrantied for two years, so I wanted to get it checked before the car's two year anniversary date. Apparently no problems here, either.

I also requested a software update to help improve the accuracy of the Carwings fuel economy tracking. Up until now, Carwings has been under-reporting our power usage in driving the car, and so their calculated energy economy has been ridiculously high and inaccurate. After some research on the My Nissan LEAF forum, I found the software update number NTB11-041 and I gave the number to the engineers. They were able to enter the software update through the SD card slot on the car's head unit. Checking on the Nissan Carwings Owners' Portal, however, our energy economy numbers are still much higher than the instruments in our LEAF actually report, so I'm not seeing any real effect from the software update.
All of this maintenance, along with the other recommended year-two checks was free of charge, and our dealer, Connell Nissan, also washed the car for us. At 21,500 miles, all four tires are worn down to the wear bars and need to be replaced. I'll get new tires in April, and this will be the first significant expense with this car for us, since we've spent less than $100 dollars in almost two years so far.
Next month, I'll wrap up two years of ownership for our Nissan LEAF.
