Reliability information

[mkaresh]

I've been meaning to drive the Touring, but haven't. And now I probably can't find one to drive.

Tires and suspension tuning could make a big different in instrumented test scores. Their test scores do not include reliability. Reliability is reported separately from the road test score. There should be just one reliability score, not one of the base and one for the Touring.

Updated results have been posted. Thanks to excellent participation by Prius owners--thanks guys--we have results for all years of the current Prius, with relatively large sample sizes from 2005 on.

Repair rates continue to be very low for the 2005, 2006, 2007, and 2008. The repair rate for the 2004 has increased, to where it's just a bit better than the average. But it's worth noting that the sample size is smaller, and that these cars have an above-average number of miles on them--71,200, on average.

With the November update it should be clearer if this is a brief blip, or a sign that the cars are starting to reach a point where they'll require more attention.

Additional participants always helpful. I'd especially like to have results for the Gen1 cars, but there are clearly fewer owners to draw from.
