I've posted the latest results of TrueDelta's reliability survey to the site. These are for the year ending December 31, 2006.

I have not yet started collecting data on the 2007 Chevrolet HHR because not enough owners are signed up. For both model years more participants would help a great deal.

For the 2006 Chevrolet HHR, I have an average of 6.4 months of data on 22 cars. The stat of 1.1 successful repair trips per year is among the worst. I suspect that with a larger sample the stat would be a bit lower. I also tend to see higher repair rates for the first model year of a car.

On the other hand, we're still only talking about a single repair trip per car, on average. And many owners have reported no repair trips.

TrueDelta Vehicle Reliability Survey results

Note that Consumer Reports' annual auto issue, out soon, includes reliability ratings for the year ending March 31, 2006. Because TrueDelta's surveys are more frequent, and we analyze the data promptly, our results will average over ten months' "fresher" than theirs. When considering a car, do you want to know how reliable it was a year ago, or how reliable it has been recently?

 

Thanks this is great.
