TrueDelta has updated Car Reliability Survey results for the G37 to include owner experiences through December 31, 2010.

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

2010: 13

2009: 31

2008: 39

These appear to be good numbers when compared with other manufacturers.

Go to Car Reliability Comparisons

and join. I just did. Then you can see the full results of their research, and can contribute to it with your own experiences.

 

I just joined, but I couldn't add to the survey. I put the eng/trans package and sedan in.

 

this was one of the reasons I got a G instead of BMW. great website. gas mileage section is very interesting as well.
