Reliability information

mkaresh · 06-18-2008, 05:51 PM

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.

The full set of results:

It's been three months, so the Vehicle Reliability Survey results for the Toyota Prius have been updated again. Repair rates remain very low for all model years.

We've had excellent participation by Prius owners. A big thanks to this forum and everyone who has been helping. We'll have further updates in May, August, and November. Additional participants always helpful. Especially need more 2004s and 2009s.

We now have a separate results page for each model that includes the results for competitors. The page for the Prius:

So based on the reliability results. Should I buy the extended 7yr/100k warranty or not? I have a 2006 and need to decide in about 3 months.

Our results (as well as others') suggest that there are few cars for which an extended warranty makes less sense.

I'd only buy one if you absolutely want to limit your potential repair expenses.

ok. thank you.

Has been for a few years.

We have updated results for the Prius to include owner experiences through March 2009. In terms of successful repair trips per 100 cars per year:

2008: 5

2007: 11

2006: 18

2005: 13

2004: 29

All are much better than average.

A big thank you 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 information and cover all model years.

We'd especially like to have a quick result for the new 2010.
