Our reliability stats for the HHR 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:

2009 HHR: 13, low, small sample size
2008 HHR: 13, low, very small sample size
2007 HHR: 76, moderate, small sample size
2006 HHR: 69, moderate

If a model year isn't listed, or its sample size is small, then we especially need more owners involved.

It's a great wee buggy it tis! We love our 2007 LS 2.2 l auto! 320,000 k or 198,800 miles and still rocking in the free world! But rust! Never sleeps, I just had to clean up a little blister on both rear quarters, I think more caused by stone chips, then from through the sheet metal.

 

We've updated our reliability stats for the HHR to include owner experiences through September 30, 2015. In terms of repair trips per 100 cars per year:

2009 HHR: 20, low, small sample size
2008 HHR: 21, low, very small sample size
2007 HHR: 102, high, very small sample size
2006 HHR: 68, moderate

We'll have further updates in February and in May. Additional participants are needed to provide precise stats for all model years.

We've updated our reliability stats for the HHR 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:

2009 HHR: 27, low, small sample size
2008 HHR: 38, low, very small sample size
2007 HHR: 83, moderate, very small sample size
2006 HHR: 56, low, small sample size

No stat, or a small sample size? Then we especially need more owners involved for that model year.

We've updated our reliability stats for the HHR to include owner experiences through June 30, 2016. Reliability information elsewhere is based on a survey conducted in April 2015--well over a year ago.

Repair frequencies, in terms of repair trips per 100 cars per year (lower is better):

2009 HHR: 28, low, small sample size
2008 HHR: 61, moderate, very small sample size
2007 HHR: 77, moderate, small sample size
2006 HHR: 49, low, small sample size

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