    We have updated results for the Prius to include owner experiences through June 30, 2011.

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

    2011: no repairs reported yet, 22 cars - especially need more of these

    2010: 10

    Both are 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.

    In the case of the Prius, these two stats are:

    2010: 91, 1

    Toyota Prius Lemon-odds and Nada-odds

    We'll have further updates in November and February. The more owners participate, the better this information will be.

    I'm curious why you and your lesser-known rival, JD Power, don't categorize these repairs. My 2010 needed a seatbelt latch replaced. That's not anywhere remotely similar to "Transmission Failed" or a condition that required a tow.

    I've been working on doing this, and it's clear why it hasn't been done before--while a simple idea it's very hard to execute in a way that will provide valid, useful information.

    First, you need to know precisely what was repaired and/or how completely the part failed.

    Second, how much more should a transmission problem count? Twice as much? Ten times as much?

    Also realize that for cars under warranty transmission failures and tows are both very rare. And if you want to accurately measure something that is rare, you'd best have a very large sample size. Which no one does for all car models.

    A problem which causes the car to not run or become un-drivable should be considered much more seriously than a problem in which the car is drivable and the dealer repair takes less than two hours.

    Updated stats again next month.

    With the Prius now split into three lines, we especially need more participants for recent model years.

    How close are you to having sufficient number of 2014 model year Prius vehicles to begin posting data?

    For some reason only 11 2014s are signed up so far, well below other model years. Need more of these!
