Agree about the '11/'12 vs '13 and after thing. While it's true I purchase my '12 used and may have avoided some of the "issues" with a new car, I have had my share of "issues" with my new purchased '13. Don't get me wrong, I much prefer the '13 for not only the better battery but also features added in '13 I really like but what I don't like is the issues.
I owned 3 new cars before the Leaf, all used for 10+ years and with none of them did I really have any issues before the warranty ran out, truthfully I had little issues even after the warranty ran out other than maintenance issues you'd have with any car. For the record 2 were Japanese cars(1 Toyota 1 Toyota/Scion) and 1 a Korean car(with a Chevy name). I started having minor issues with my '13 Leaf within months of purchase. None were major(well actually one was kind of) but they were all irksome that I should really have any issues with a new vehicle, after all that's why I like to buy new and sell at 10 years, before issues start. Following is a list of the "issues" I've had with my '13 noting in months when I first noticed and got the issue fixed, I think I got them all.
1. 3 months, Rear door hatch had to be SLAMMED to latch. After a couple trips to the dealer, first time they adjusted the catch and second time they replaced the catch, third time they ended up replacing both rear hatch struts and it's been fine since.
2. 6 months, Klunking from front end mainly when backing up in the cold(teens or colder). After 2 trips to the dealer they ended up replacing several front end parts and clunking stopped for about a year, it's back now but maybe not as bad as before, I just live with it and hope it doesn't get worse again.
3. 1-13 months, Front tires quickly wearing on both outer edges. I didn't really notice this until they were mostly bald on the outside edges and by the time I brought the vehicle in it was a bit past the 1 year mark(10k miles) and unfortunately aligning the front end for free ended at 1 year so I paid the ~$100 to have it done. Note I had never hit anything or hit any bad pot-holes and it's my belief the vehicle was out of alignment from the factory, I remember noting it shortly after getting the car but didn't really put 2 and 2 together until the tire was basically bald on the outside edge, my fault for not reporting it earlier and because of this I had to replace my tires at about 20k, WAY earlier than I feel I should have. Note after the alignment the replacements seem to be wearing fine.
4. 18 months to current, Door handle comes part. I haven't brought this in for service as it only happens occasionally and it's always snapped back together, it also only happens if I pull the handle too hard when I think the car is unlocked, but it isn't.
