We’ve updated the Car Reliability Survey results to include owner experiences through December 31, 2009.

The new email process, which reduced the number of emails to members whose responses were up-to-date, was a big success. For the past year the response rate has been about 36 percent. This time around it was 38 percent. In absolute terms, we received responses for over 15,400 cars, up from 13,140 three months ago.

This was enough to provide full reliability stats for 355 car models, compared to 295 three month ago, and partial results for another 291. Coverage for the “odds” stats increased from 99 to 125.

I’ll cover some notable results in future blog entries.

A big thank you to everyone who helped make these results possible. The more owners participate, the more information we can provide.
