I lost my first battery capacity bar a week ago (about August 26, 2012). I noticed it after one of my infrequent 100% charges.
SOC bargraph now shows higher than battery capacity bargraph after 100% charge. Hmmm....
8500 miles, 2012 model year, leased Dec 20, 2011. Gilbert AZ (Phoenix Metro area). Contacted Nissan direct (not dealer), got a case number. Leasing is beginning to look better all the time.
I use L3 chargers about 6-8 times a month, and charge to 100% at home about as often. Home charging to 80% occurs after midnight, every night. During the hotter months, I've been enabling climate timer while on the charger, which also continues charging to about 90% typically.
Most of my driving is to/from work, about 15 miles each way, usually on side streets about 45 MPH, averaging about 4.6mi/kWHr, occasionally reaching 5.0mi/kWHr. Freeway driving is limited to 65 MPH (3.9-4.2mi/kWHr). Almost always in ECO mode (except when I notice it's not).
Once or twice a month, I take a trip to Glendale to visit parents (about 60 miles each way, with a stop on the way out). Carwings suggests that such round trips draw about 38kWHr. I've got modified "trickle" EVSE, so can charge from 240V (3.3kW) at parents - BIG help!
The last couple trips to parents have been... troublesome... each way, reaching VLB before reaching destination. At various times, I thought it was due to 1) Monsoon heat taking its toll on A/C, 2) brothers' driving technique on the last trip (but he drives a Prius and is "qualified"), then finally 3) Monsoon heat AND humidity.
Fortunately, there's now an L3 not far west of the mall in Scottsdale for the trip to Glendale in the afternoon (untried), and another in the ASU Research park (available 24/7, confirmed) for the return trip late in the evening.
Tangential story follows -----------
During the last trip to parents, got stranded at Bell Road Ford, planning on using the L3 DCFC. Got there with 6 miles range (indicated), 15 miles to go, and _ALL_ Blink chargers were non-functional (L3 powered off, one L2 failed self test, other L2 charged for 3-5 seconds before stopping). After panicking briefly :evil: (and forgetting there were other L2 chargers in range) one of the sales people pointed out a Ford branded L2 charger in front of showroom, but no one knew if it worked. After locating and turning on the power service switch, was able to charge for an hour and be on our way. Friendly sales people - got lit for Focus Electric (said little about electric systems, similar to Leaf).
Side comment - I'd really appreciate a J1772 charger at Scottsdale Fashion Square Mall. They've got a pair of Tesla HPC chargers (WTF?!? - 'xcuse the language).
