Reliability info on the Gen III Prius -- help make it happen

We've released an updated reliability stat for the redesigned 2010 Prius that includes owner experiences through March 31, 2010.

We had 127 responses, outstanding for such a new model. The reported repair rate of 13 repair trips per 100 cars per year remains similar to those for the 2007-2009, and excellent for a redesigned model early in its first model year.

We now have two additional statistics, "Nada-odds" and "Lemon-odds," to indicate the percentage of cars with no repairs in the past year and those that required 3+ trips to the repair shop.

In the case of the 2010 Prius, the percentage with no repairs is about 80. The percentage of lemons is less than one.

A big thank you, once again, to this forum and everyone who has been helping. We'll have further updates in August and November. The more owners participate, the better the information we can provide.

Starting this month we have a new question to measure, as objectively as possible, the severity of a problem. Many people have been asking for reliability stats that weight problems by how severe they are, and once we have enough responses with the revised survey we'll start providing this.

Also, updated reliability stats this month.
