2011 Nissan Leaf: 11K Miles, No Battery Issues, Defroster Needs Work

Follow Nikki

Back at the end of March, I took delivery of our very own 2011 Nissan Leaf electric car. So far, we’ve told you about long-distance drives, explained five things we’ve learned after 5,000 miles, and what we’d learned after 5 months with the car

But as fall quickly heads towards winter and the holiday season is upon us, we’re getting an even better feel for the car we’ve driven almost every day for eight months. 

Battery still healthy, gives good range

While Nissan sells all Leafs with an 8 year, 100,000 mile warranty on the battery pack, it has also said publicly that it expects most Leaf battery packs to only be capable of storing 70 to 80 percent of its original capacity after ten years. 

But after 11,000 miles we’ve yet to notice any perceptible drop in pack capacity. Even with more than 25 rapid charges in the last eight months and the majority of our home charging carried out to 100 percent rather than 80, our battery pack appears healthy. 

We’ve noticed no perceptible drop in range either, with our Leaf offering between 50 and 90 miles of range per charge depending on driving style, weather, and road conditions. 

Remote pre-heating needs work

Our car, a 2011 model without winter package, doesn’t have the luxury of a garage to stay in at night. Instead, it is parked and charged on a driveway, exposed to all weather. 

During colder Fall nights, we’ve started to make use of the Nissan Leaf remote pre-heating feature to warm the car up for the daily early-morning trip to the gym. 

Set to turn on 30 minutes before our departure, the climate control system uses power from our charging station rather than the battery pack to heat the car, but like many other Leaf owners we’ve noticed that the feature has a major bug. 

On damper mornings, or days after there’s been heavy rain, we’ve woken up to find all the windows in our Leaf were steamed up with condensation.  It appears that the Nissan Leaf’s pre-heating program heats the air inside the car, but recirculates it rather than pump warm, dry air in via its climate control system.  The result is a warm, but moist interior.

The solution? We’ve found that unplugging the car and then running the air conditioning for a minute or so prior to departure -- but after using pre-heating -- helps dehumidify the air enough to clear the fogged windshield while maintaining a cosy interior temperature. 

Hopefully Nissan will rectify this problem either with a service recall, or a redesigned system on future cars as the current pre-heating system doesn’t always do what it is meant to.

  1. Strange.

    Mine turns the AC on when the scheduled pre-heat starts.

    Well, we do have a garage the Leaf sits in and we've never experienced any moisture inside, with the pre-heat feature. There's been raining a lot.

  2. Thanks for your post. It's reassuring to know that the battery is performing well despite the frequent 100% charging cycle you have used. Please let us know what your battery report shows at 15,000 miles.

    I use the pre-heat less than I would have hoped for because of the heavy fogging. Pre-heating in the morning in our garage works well. It's the return journey when its parked outside that doesn't work as well.

    Happy EV motoring.

  4. Love the report and how well you describe how good the leaf is
    but i can't let "its schizophrenic range prediction"
    pass without comment,
    it's probably an inappropriate use of a specific mental health term? You're describing erratic, difficult to comprehend behaviour of the range meter, not schizophrenia? http://www.mind.org.uk/

  5. I experimented a little and found, with my Leaf at least, that the climate timer turns on the setting that I left when I set the timer. In my case I turned off the auto and turned on the AC, and that's what came on with the timer. It did however switch it to recirculate rather than outside, but that would be the better option if you have moist air outside, in my opinion. The AC should do a better job of dehydrating the small amount of air in the car, if new humid air isn't constantly being introduced from outside.
