Reliability information on first-gen Prius

We've updated our reliability stats for the Prius to include owner experiences through December 31, 2013.

Repair frequencies, in terms of repair trips per 100 cars per year:

2003 Prius: 68, low, very small sample size
2002 Prius: 47, low, very small sample size
2001 Prius: 51, low, small sample size

We'll have further updates in May and in August. The more owners participate, the more comprehensive and precise these will be.

Our reliability stats for the Prius now cover the year ending June 30, 2015. (Others are over a year behind, and so report how these cars were doing when a year younger.)

Repair trips per 100 cars:

2002 Prius: 46, low, small sample size
2001 Prius: 82, moderate, very small sample size

We continue to especially need more owners involved with this generation.

We've updated our reliability stats for the Prius to include owner experiences through the end of 2015, about eight months ahead of other sources. In terms of repair trips per 100 cars per year--lower is better:

2002 Prius: 63, low, very small sample size

We didn't have enough responses for the 2001 and 2003, and barely had enough for the 2002. Without more owners involved we probably won't have stats for the first-generation Prius in future updates.

Unfortunately, we only had enough participants for one of the three model years. This was the last round to include 2001s. But more 2002s and 2003s would be very helpful.
