Currently I'm a few responses short of being able to report a result for the 2007 Tahoe, Suburban, and Yukon. _____________________________ truedelta.com Vehicle reliability, fuel economy, and price comparison information (in reply to mkaresh) Post #: 11

RE: Chevrolet Tahoe reliability - how does it compare? - 9/4/2007 11:03:39 AM    mkaresh   Posts: 72 Joined: 3/5/2007 Status: offline The 2007s were included in the August results, with a worse than average repair rate. The sample size was barely over the minimum for even an asterisked result, so a very general indicator at best. With more participants the result would be more precise, and that asterisk could be removed.

Hopefully I can get rid of that asterisk. I think I'm going to start including the Avalanche in the totals, which will help.

It would appear to me as your sample size is no where near the minimum requirements to have any significant confidence level.  What are your parameters? I.e. your confidence level and interval? Population size say for the chevy cobalt? _____________________________ 2008 LTZ Tahoe - Summit White / Light Cashmere Leather / Chrome Package / LED Tails / Chrome front & rear bowtie / GMX320 Lockpick / Ipod Lockpick / 8000k HID / WeatherTech Floorliner / Wood Trim Armrest & 4wd Switch / 3M ClearBra (in reply to mkaresh) Post #: 14

RE: Chevrolet Tahoe reliability - how does it compare? - 9/28/2007 4:27:27 PM    mkaresh   Posts: 72 Joined: 3/5/2007 Status: offline Unless the size of the population is small, there is no relationship between the size of the population and the size of the sample needed to evaluate this population. That there is a relationship is a common misconception. The necessary size of the sample is driven by the amount of variance within the population. The results start to provide a general indication with as few as 15 responses and really start to stabilize over 25. It helps that I'm currently focusing on a metric with relatively low variance, the average number of repair trips per year. Of course, the larger a sample size is, the better. They'll get where they need to be. _____________________________ truedelta.com Vehicle reliability, fuel economy, and price comparison information (in reply to GIXXER) Post #: 15

RE: Chevrolet Tahoe reliability - how does it compare? - 10/20/2007 8:17:22 AM    mkaresh   Posts: 72 Joined: 3/5/2007 Status: offline When I have enough participants, I'm months ahead of anyone else. CR reported problems with the Camry V6 this past week. TrueDelta reported these problems back in August. We'll be reporting a repair rate for the 2008 Buick Enclave in a couple of weeks. CR will be reporting on the Enclave this time next year. I know this wasn't the best news for Tahoe owners, but we also reported iffy reliability for the GMT900s months ago. CR's rating, incorrect for the past year, was only corrected this past week. Our sample size isn't as large as theirs. But we've still be providing accurate results well ahead of them and JD Power. _____________________________ truedelta.com Vehicle reliability, fuel economy, and price comparison information (in reply to mkaresh) Post #: 16

Other years are getting close to the minimum.

RE: Chevrolet Tahoe reliability - how does it compare? - 11/16/2007 1:50:13 PM    ZX1100F1 Posts: 2433 Joined: 8/1/2006 Status: offline Looks like an epic waste of time to me. Similar (and most likely more detailed) data is compiled by numerous organizations that is readily available to the public. Reliability isn't modern consumers driving force, the worst cars sold in America are very reliable. Not to mention the fact that the new long-term manufacturers warranties will ease even the biggest cynics worries. (in reply to mkaresh) Post #: 18

RE: Chevrolet Tahoe reliability - how does it compare? - 11/16/2007 2:42:23 PM    mkaresh   Posts: 72 Joined: 3/5/2007 Status: offline You might want to take a closer look... I recently posted a repair rate for the new Buick Enclave. Can you find a single additional source of this information? With TrueDelta's research process, the results are promptly updated four times a year. On average, our data are over nine months "fresher" than that of Consumer Reports. Second, TrueDelta posts actual repair rates. Can you find another source that provides more than vague dots? So much for that additional detail. Finally, if people did not continue to be concerned about reliability, GM and Ford would be in much better shape. _____________________________ truedelta.com Vehicle reliability, fuel economy, and price comparison information (in reply to ZX1100F1) Post #: 19
