    I wanted more up-to-date car reliability information that included actual repair rates. So in late 2005 I started getting people together to make this possible. TrueDelta now reports absolute repair rates that make the differences between cars much clearer. Results are updated four times a year, so it's possible to track cars closely as they age.

    Over 240 GMT360 owners have already signed up to participate. A good start, but more are needed to provide full results for all years. So I'm grateful that this forum has given me permission to post this thread.

    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, at the end of each quarter.

    To encourage participation, participants receive full access to all results, not just those for the TrailBlazer and Envoy, for free.

    For the details, and to sign up to help out:

    We've updated the results for the TrailBlazer, Envoy, and other GMT360s to include owner experiences through September 30, 2009. In terms of repair trips per 100 cars per year:

    2006: 115, worse than average

    2004: 98, about average

    2003: 61, better than average

    2002: 17, better than average

    The sample sizes were small in all four cases, which likely explains the highly inconsistent results. With more participants, these would even out.

    Everyone who has been helping, thanks, I appreciate it. We'll have further updates in February and May. If you haven't already signed up to participate, I hope you will. With more participants we could provide full results for all model years from 1995 on.

    2006: 94, about average

    2004: 114, about average

    2003: 44, better than average

    2002: 35, better than average

    The sample sizes were small in all four cases, which likely explains the highly inconsistent results. With more participants, these would probably even out.

    A big thank you, once again, to this forum and everyone who has been helping. We'll have further updates in May and August. If you haven't already signed up to participate, I hope you will. With more participants we could provide full results for all model years from 1995 on.

    We've updated the results for the TrailBlazer, Envoy, and other GMT360s to include owner experiences through June 30, 2010.

    Other sources of car reliability information won't cover the more recent months until the summer or even fall of next year.

    In terms of repair trips per 100 cars per year:

    2006: 72, about average

    2005: 67, about average

    2004: 54, better than average

    2003: 47, better than average

    2002: 67, better than average

    Barely reached the minimum for a full result with the 2002. Small and even very small sample sizes with the others.

    Thank you, once again, to this forum and everyone who has been helping. We'll have further updates in November and February. With more participants we could provide full results for all model years.

    I'm glad you found it helpful. I must admit, though, that our GMT360 info is held back by small sample sizes. If we could get more owners involved the results would be far more comprehensive and precise.
