    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 report on new models quickly then to track cars closely as they age.

    We already provide some reliability stats on the Suburban and Yukon, but would like to cover all years from 1995 on. For this, we need more participants. So I'm grateful that the owner of this forum has given me permission to post here. We're linking back from our results pages for these SUVs.

    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 Suburban and Yukon, free of charge.

    Updated results soon.

    We're going to start providing new stats for the odds of requiring no repairs and the odds of getting a lemon. These require larger sample sizes, so additional participants would be helpful.

    We've updated the results for the Tahoe, Yukon, and Suburban to include owner experiences through September 30, 2009. In terms of successful repair trips per 100 cars per year:

    2007: 58, about average

    2005: 59, about average

    2004: 53, better than average

    2003: 124, about average

    2002: 22, much better than average, does not appear accurate.

    We only had a sufficient sample size for the 2003 and 2007, so those stats are the most accurate. The others are asterisked and only visible to members on the site itself.

    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.

    523 large GM SUV owners now signed up. A good start, but more are needed to provide precise results for all model years.

    We've updated the results for the Tahoe, Yukon, and Suburban to include owner experiences through December 31, 2009. In terms of repair trips per 100 cars per year:

    2008: 76, about average

    2007: 69, about average

    2005: 60, about average

    2004: 81, about average

    2003: 125, worse than average

    2002: 30, much better than average

    Results for 2002 and 2003 do not appear to be accurate.

    Everyone who has been helping, thanks, I appreciate it. We'll have further updates in May and August. With more participants we could provide more precise results for all model years from 1995 on.

    Just enhanced the related repair history survey so that it can (optionally) be used as a personal car maintenance record.

    As always, more participants would be helpful. Updated Car Reliability Survey results in May, with a preview for participants in mid-April.

    We've updated the results for the Tahoe, Yukon, and Suburban to include owner experiences through March 31, 2010. In terms of repair trips per 100 cars per year:

    2008: 101, worse than average, and than earlier

    2007: 116, worse than average, and than earlier

    2005: 59, about average

    2004: 81, about average

    2003: 115, about average

    2002: 76, better than average

    2001: 194, worse than average, small sample size so less precise

    Thank you, once again, to this forum and everyone who has been helping. We'll have further updates in August and November. With more participants we could provide more precise results and cover all model years from 1995 on.

    Interesting stuff.
    You don't have any numbers on 96-99 Suburbans do you?

    Is there any way to subdivide the repairs so you can make a guess on which is most likely to leave you on the side of the road vs just being a big inconvenience?
