 I am filing a complaint about the main battery in my 2011 nissan leaf. according to nissan, i should have expected about a 20% battery capacity loss after five years of ownership. i have had the car for 14.5 months. as of 8/29/2012, the battery has lost 3 bars of capacity (approximately 27.5% capacity loss). this rate of capacity loss is far beyond what nissan expected and possibly modeled/engineered. please help insure there will not be any safety issues with the battery as the capacity deteriorates. *tr

 I have run into what i believe is a small design flaw. scenario: 1) leaf is parked in condo parking garage with gentle uphill slope on parking space. 2) startup sound is turned off. 2) forget the leaf is still plugged in to av l2 evse. 3) put foot on brake, push start button. 4) shift into reverse, not looking at dash screen to see warning that leaf won't start. 5) press down on parking brake lever to disengage parking brake. 6) press accelerator. result: the leaf doesn't start since it is still plugged in to evse. the leaf shifts out of park into neutral after step #4. once parking brake is off and foot is on accelerator, there is nothing to keep the leaf from rolling back. if it rolls far enough it will damage either the l2 connector to the car or the evse or both. comment: this is not a hypothetical, it has happened to me 3-4 times in the last year. fortunately, i quickly realized the leaf was still connected to the evse and applied the brake so that no damage was done. in my opinion, you should not be able to shift the leaf out of park or release the parking brake while the leaf is still plugged in. i would suggest changing the software to avoid potential damage to the leaf l2 connecter, evse or damage to property in the vicinity. *tr

 I have run into what i believe is a small design flaw. while user error is clearly involved, a simple software fix could prevent this from happening. scenario: 1) leaf is parked in grocery store parking lot on a slight downhill slope. 2) startup sound is turned off. 3) push start button while not pressing on brake pedal adequately - leaf goes into accessory mode. 4) try to shift into reverse, not looking at dash screen to see that leaf is in accessory mode. 5) press down on parking brake lever to disengage parking brake. 6) press accelerator. result: the leaf is still in accessory mode, but has shifted into neutral after step #4. once parking brake is off and foot is on accelerator, there is nothing to keep the leaf from rolling forward. this is not hypothetical, it happened to me twice in the last year. one time i hit a shopping cart, but fortunately put the brake on in time and the front license plate holder protected my leaf from damage. comment: in my opinion, trying to shift into drive or reverse while the leaf is in accessory mode should not put the leaf in neutral--it should still be in park. this simple change would prevent the possibility of this happening. the leaf can still shift to neutral in accessory mode by moving the shifter to the left and holding it there for 2 seconds. *tr

 The nissan leaf is a 100% battery operated vehicle. there is a built-in battery capacity indicator that is displayed as 12 indicator bars. each bar represents a % of the batteries capacity to hold a charge. nissan claims that gradual capacity loss is normal and that driver should expect to have 80% of their capacity left after 5 years and 70% after 10. i lost my first bar at the beginning of april, second bar first week of june, and third bar first week of july. nissan has not defined what these bars mean, however, i do not believe that the loss of three bars in 4 months after owning the car for a year is gradual. i have sent my car to 2 different nissan dealerships and even let nissan north america take my car for 16 days for testing. so far, nissan has told me that everything is normal. i believe that having a 100% battery operated vehicle marketed to a mass customer base and being driven on our streets and highways should have a dependable battery. *tr

 About a month and a half ago, i purchased a 2011 nissan leaf from my local dealer. everything was going great until about a month ago when i was driving on the highway around 20 mph or so when the power suddenly shut off. the entire dashboard instantly went off but the radio+touchscreen remained on. the car came to a crawl and i was able to pull over and restart without any problems. it was a little scary to say the least. i called the dealership where i bought the car from and left a voice mail for the service dept. since it was saturday but never received a call back. i kind of shrugged it off that day thinking it might have just been a quirk so i didn't follow up with the dealer. about a week and a half ago, i was pulling into a parking lot going around 10 mph and the same thing happened. i called the dealership and took it in the next day. they've had the car for about a week and said that nissan told them to drive it and try reproducing the problem. i didn't expect them to reproduce it since it has only happened twice within weeks. as expected, they couldn't reproduce it so i was told that i would have to take the car back since they couldn't do anything about it. i am taking the leaf back tomorrow to start driving again but definitely have concerns since my wife also drives the car and who knows what she would do in a shut-off while driving situation. luckily, the past two incidents were not in high speeds and i was able to react quickly. my worst nightmare would be if we got rear ended due to instantly losing power. i have called nissan directly to let them know about my car but no one has called me back. i assume they were already in touch with the dealer. i don't like the fact that i am being handed the car back at a potential safety risk. *tr

 I borrowed a leaf from a co-worker to drive overnight. i parked in my driveway (not by a plug) and plugged the 110v charger into an extension cord to charge the battery. i awoke at midnight to a strong burned plastic/ozone type smell in my bedroom, which is above the garage. i went to the garage and found the extension cord was overheating, melting the plastic insulation from the wiring. i disconnected it, opened doors for a while to air out the house and went back to bed. glad i had enough battery to get to work the next morning. my concern is that i assumed the car charger was self regulating so it wouldn't be a problem using an extension cord. as a borrower, i didn't read an owner's manual or any information warning me to avoid an extension cord. i'm very strong auto-technology based, yet still made this dumb mistake. it was dark, i was in a hurry to get home, quickly plugged it in and went inside. if i wasn't sleeping near the garage, i assume it would have continued this path of overheating until the wire burned thru or a fire occurred. i assume if someonei plugs it directly into old wiring in a house, it could overheat that wiring too. i expect many people could do the same thing as i did since no one has a plug outside, and no one in california can actually get a car in their garage because its filled with stuff. i have no problem with the car as it was marvelous to drive. but this charging issue needs to be looked at closely since we are beginning to read stories of house fires with evs.
