Signing up after this post.Guess I'll find out if you can enter past issues fixed in prior mo/yrs?

In a nutshell...Both window motors replaced; drivers window regulator replaced and a new VQ35DE revup due to Oil Consumption per TSB.

[mkaresh]

Past issues aren't reportable on the main survey. That one collects data going forward.

You can report past repairs on a second survey, the Vehicle Repair History survey. Unlike the main survey, which is only accessible through links in emails I send out, you can get to the second survey by going to the site.

[CPV35GT]

^ Understand and will do that. Repairs are repairs and contributes to past history stats.

[mkaresh]

Updated results in August for all years 2003 on.

As noted in the updated OP, three model years already have over 100 owners signed up, and the 2003 is now at 98.

Help us provide the best possible information on your year:

Add one more....2005, 5AT to the list.

The G recently became the first model with 100+ owners signed up for each of four model years. Great job, guys!

Of course, with sample sizes more is always better. So anyone who hasn't signed up--your participation would be helpful.

We did recently post the latest results. Most model years for the first-gen G35 are average or a bit better than average. The 2005 is a bit worse than average, which is probably an effect of the small sample size rather than an indication that that year is different than the others.

The 2007 continues to be on the low edge of average, because of the common problems with the seat heater wiring and a piece of sunroof trim. The repair rate for the 2008 is a bit better than average.

Next update in November, with a preview for participants next month.

623 G owners signed up so far. An awesome start...but more is always better.

We're going to start performing more complex analyses soon for models with large sample sizes. Some years of the G could qualify.

This month's survey is the last before the February results. As always, additional participants would make it possible for us to provide better info to everyone.

TrueDelta has released updated Car Reliability Survey results for the Infiniti G35 AND G37. In terms of successful repair trips per 100 cars per year:

2008: 50; about average, large sample size

2007 sedan: 72, about average

2007 coupe: 16, better than average, very small sample size

2006: 27, better than average

2005: 80, about average; other results suggest actual repair rate is lower

2004: 33, better than average

2003: 47, better than average

Overall, the Gen 1 cars seem to require fewer repairs than the current generation, despite their greater age. It's possible that the repair rate for the current cars will improve one a few initial problems drop out of the analysis, which always covers the past year.

A big thanks to everyone who has been helping. We'll have further updates in May, August, and November, so additional participants would certainly be helpful.

TrueDelta now has a separate results page for each model that includes the scores of competitors for easy comparisons. The one for the Infiniti G35 / G37:

I just signed up my 2004 G35.

I bought in new in Sep 2004 and it has been flawless. I have 87,000 on it and plan on taking it at least that many more.

[mkaresh]

Thanks, I appreciate it.

The G35/G37 recently became the first model with 100+ owners signed up for each of five model years. Thanks, guys.

That said, with sample sizes more is always better, and we badly need more 2007 coupes and more 2009s.

I'm already signed up for my G37x, after my participation for over the last 2 years with my M35x. I notified them that I had sold my M and bought the G.
