I've had the car in the shop for repairs precisely zero times, and the one actual problem I've had was mostly my own damn fault and once I figured out what was going wrong it was a literal 5 minute fix. I'd call that zero issues.

And the air cooled battery is literally not an issue unless you fast charge it multiple times in a day. The number of times I fell under that scenario in 4 years of ownership was precisely once, when I going on a weekend road trip for my birthday, and I opted to rent a hybrid for that instead. I consider something that covers literally 99.999% of my driving needs, has needed zero shop time beyond routine maintenance, and has saved me literally thousands of dollars in gas money to be a pretty good deal.

Now, to be 100% fair, I wouldn't recommend someone buy a Leaf today because its CHAdeMO fast charger is obsolete. But the car itself is perfectly fine.
