I wanted more up-to-date car reliability information that made the differences between cars clearer. So a few years ago I started getting people together to make this possible. TrueDelta now updates actual repair frequencies, not just dots, four times a year, to report on new models like the LEAF sooner then track cars closely as they age.

Greg and NICOclub have long been an active partners in this project, and I am very grateful for their support. Partly as a result, we've been providing excellent information on many Nissan and Infiniti models. I'd love to do the same for the LEAF--just a matter of getting enough owners involved.

Participants simply report repairs the month after they occur on a one-page survey. When there are no repairs, they simply report an approximate odometer reading four times a year, following the end of each quarter.

To encourage participation, participants receive full access to all results, not just those for the LEAF, for free. I'll share results for in this thread after each update.

I should add that we only need a couple more participants to have some initial stats in November--so we're close!

Leaf owners, please sign up, this will really help prospective owners get over any fears of such a new technology and make an informed decision regarding the purchase, thank you.

We have an updated result for the Nissan LEAF based on owner experiences through December 31, 2011.

So far no non-software repairs have been reported, for 56 cars.

We'll have further updates in May and August. The more owners participate, the better the information we can provide.

We have an updated result for the Nissan LEAF based on owner experiences through June 30, 2012.

Repair frequencies, in terms of repair trips per 100 cars per year:

2012: 14, small sample size

2011: 6

Both are much better than average.

We have two additional statistics, "Nada-odds" and "Lemon-odds," to indicate the percentage of cars with no repairs in the past year and those that required 3+ trips to the repair shop.

These stats for the LEAF:

2011: 91, < 1

We'll have further updates in November and February. The more owners participate, the better the information we can provide.

Actually, reliability is near the bottom of worries for an electric car for me. The biggest problems are usually software related, things like stuck blue-tooth connections that drain batteries and things like that. Drivetrain-wise, I'd take my luck with electric any day. Going to be lot less maintenance.

this will really help prospective owners get over any fears of such a new technology and make an informed decision regarding the purchase,
