I've posted the latest results of TrueDelta's reliability survey to the site. These are for the year ending March 31, 2007. (CR currently provides results through March 31, 2006, making their data a year older.)

For the 2006 Chevrolet Cobalt I have an average of 5.2 months of data on 23 cars, two short of the bare minimum I require to consider a result "official." So the result is asterisked and on the site is visible only to members. The stat of 60 successful repair trips per year per 100 cars (0.6 per car) is about the average for a 2006 model.

I did not have enough participants for the 2005 and 2007 to even include them among the asterisked results.

Next results in August. Hopefully I'll be able to report on other model years then.

Those of you who have been helping out with this, thanks. If you're not yet helping out, please consider doing so. The larger the sample, the more precise future results will be.
