Updated reliability stats next month.

As always, the more owners participate, the better the information we can provide to everyone.

We've updated the results for the 5-Series to include owner experiences through September 30, 2010. Other sources of car reliability information won't cover the months since April until the summer or even fall of next year.

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

2009: 31, better than average, more participants needed to split by engine

2008 528/550/M5: 56, about average

2008 535: 71, about average

2007: 111, worse than average

2006: 122, worse than average

2005: 50, better than average, but very small sample size and results for other years suggest that this one is not accurate

2004: 150, worse than average

2003: 90, about average

2002: 83, better than average

2001: 234, small sample size; actual repair frequency probably lower but still worse than average

2000: 117, about average

1999: 128, about average

Sample sizes small for all but the 2006, 2007, and 2008. This likely explains some inconsistencies from model year to model year. With more participants, we could provide more precise information and cover all model years.

Thank you, once again, to everyone who has been helping. We'll have further updates in February and May.

We have some new pages that display all reported repairs by problem area:

2008 BMW 5-Series problem reports

From this page it's possible to select a different model year or specify a problem area.

We've updated the results for the 5-Series to include owner experiences through December 31, 2010. Other sources of car reliability information won't cover the months since last April until the summer or even fall of this year.

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

2011: 68, about average, small sample size

2009: 32, better than average, more participants needed to split by engine

2008 528/550/M5: 51, about average

2008 535: 60, about average

2007: 106, worse than average

2006: 97, about average

2005: 86, about average, very small sample size

2004: 148, worse than average, first year of E60, small sample size

2003: 77, better than average, small sample size

2002: 124, about average, small sample size

2001: 215, worse than average

2000: 118, about average

1999: 181, worse than average, very small sample size

Sample sizes small for all but the 2000, 2001, 2006, 2007, and 2008. This likely explains some inconsistencies from model year to model year. With more participants, we could provide more precise information and cover all model years.
