The latest TrueDelta Vehicle Reliability Survey results have been posted. These are for the year ending September 30, 2007, six months more recent than other sources.

Repair rates are again very low for all four model years of the current Prius, 2004 to 2007. The results for the 2004 is based on just 17 responses, so it is asterisked. The sample sizes for other years ranged from 44 to 52.

Everyone who has been helping out with this research, thanks, I literally couldn't have done it without you. Those who aren't yet helping out, please consider doing so. I'd like to eliminate the asterisk on the 2004 and report results for both the 2008 and the first-gen Prius.
