    I notice the 2004 Prius has fewer repair trips/yr than any other vehicle that old except for the 2004 Lexus RX among TrueDelta's statistically significant stats.

    Next update is next week.

    The hard part with older cars is that at some people start living with problems rather than fixing them. When comparing cars of the same year this should cancel out. I have noticed that the only cars reliable for 10+ years are either Hondas or Toyotas (and not all of these). The Prius is a reliability champ.

    We have more people selling than buying cars of this vintage, so additional participants--for any year--would be very helpful.

    We've updated our reliability stats for the Prius to include owner experiences through September 30, 2014.

    Repair frequencies, in terms of repair trips per 100 cars per year--the Prius is as boring as ever:

    2009 Prius: 19, low
    2008 Prius: 20, low
    2007 Prius: 23, low
    2006 Prius: 35, low
    2005 Prius: 33, low
    2004 Prius: 25, low

    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:

    2009 Prius: 83, < 1
    2008 Prius: 80, < 1
    2007 Prius: 76, < 1
    2006 Prius: 69, < 1
    2005 Prius: 68, < 1
    2004 Prius: 79, < 1

    New stuff this time. We've updated our reliability stats for the Prius to include owner experiences through the end of 2014. Plus we've added reliability trends graphs. These indicate how a model's reliability has changed as it has aged, and how different model years performed when the same age.

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

    2009 Prius: 22, low
    2008 Prius: 27, low
    2007 Prius: 20, low
    2006 Prius: 33, low
    2005 Prius: 34, low
    2004 Prius: 24, low

    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:

    2009 Prius: 77, < 1
    2008 Prius: 76, < 1
    2007 Prius: 85, < 1
    2006 Prius: 74, < 1
    2005 Prius: 67, 2
    2004 Prius: 70, < 1

    We'll have further updates in May and in August. The more owners participate, the more comprehensive and precise these will be.

    The new reliability trends graphs are great! They will improve as you get more years of data.

    I'm glad you like them. Like the stats on which they're based, these graphs are most precise with large sample sizes. We've got fairly good sample sizes for the Prius, but they could be better. So I hope more owners will join.

    So, how have these cars been doing lately?

    Our reliability stats for the Prius now include owner experiences through March 31, 2015. (Others are nearly a year behind.)

    In terms of repair trips per 100 cars per year ("low" is best):


    2009 Prius: 26, low
    2008 Prius: 27, low
    2007 Prius: 23, low
    2006 Prius: 30, low
    2005 Prius: 28, low
    2004 Prius: 29, low

    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:

    2009 Prius: 74, < 1
    2008 Prius: 78, < 1
    2007 Prius: 78, < 1
    2006 Prius: 79, 2
    2005 Prius: 74, < 1
    2004 Prius: 73, < 1

    Okay, not much change from...ever. Boringly consistent! Next updates in August and November.

    Our reliability stats for the Prius now cover the year ending June 30, 2015. (Others are over a year behind, and so report how these cars were doing when a year younger.)

    Repair trips per 100 cars:

    2009 Prius: 20, low
    2008 Prius: 31, low
    2007 Prius: 29, low
    2006 Prius: 22, low
    2005 Prius: 27, low
    2004 Prius: 48, low

    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:

    2009 Prius: 84, < 1
    2008 Prius: 74, < 1
    2007 Prius: 75, < 1
    2006 Prius: 79, < 1
    2005 Prius: 79, 2
    2004 Prius: 76, 8

    Additional participants always helpful.

    There seems to be a sudden spike in repairs for 2004 models. It will be interesting to see in the future if this is an anomaly or if the 11 year mark becomes a "magic number" of sorts where GenII Prius parts begin to see more failures.

    2005 Prius: 48, low
    2004 Prius: 51, low

    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:

    2009 Prius: 64, 3

    We've updated our reliability stats for the Prius to include owner experiences through June 30, 2016. Reliability information elsewhere is based on a survey conducted in April 2015--well over a year ago.

    Repair frequencies, in terms of repair trips per 100 cars per year (lower is better):

    2009 Prius: 46, low
    2008 Prius: 36, low
    2007 Prius: 31, low
    2006 Prius: 40, low
    2005 Prius: 55, low
    2004 Prius: 39, low

    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:

    2009 Prius: 68, 3
    2008 Prius: 74, 2
    2007 Prius: 76, < 1
    2006 Prius: 63, < 1
    2005 Prius: 64, 4
    2004 Prius: 65, < 1

    We'll have further updates in November and next February. The more owners participate, the more comprehensive and precise these will be.

    Has anyone seen a 2008 put a rod through the block? Got a call from my mom that she was broken down and picking up what she believed to be pieces of her car on the road. sounds like situations i've had, but those were highly modified, forced induction cars. i understand anything can pop if ignored long enough, but do these really grenade without noise from a spun bearing first? Just have a hard time believing the prius throws rods like a dragster.

    She felt she "may" have ran over something, just trying to get some ideas from the experts before i check it out. Thanks for your input. i will be happy to contribute to the thread once i can confirm a thrown rod and have all the other details you would need.

    I traded in my 2008 last month and removed it from true delta and put my new 2016 on.
    I only had 108,000 on the 08. It was the best car I ever owned and only three trips to the dealer and two were for recalls and the other was those troublesome HID light for bulb replacement. Mine was the only one I ever saw with rust on the right rear rocker panel. I blame that on where I worked in a steel mill, very corrosive atmosphere.
    Mechanically, I replaced the noisy right front wheel bearing and replaced front struts at close to 100,000 miles.
    I am expecting similar results from my new 2016 Prius.

    Wao! This is great. A job well done.
    I'd like to incorporate something like this in Nigeria, where we've got lots of issues with used cars.

    I have have PM you already @mkaresh.
