NICO saw the value of this research, and has been very helpful. When I first posted this thread, 77 G35 owners had signed up. We're now approaching 600! Back then, we weren't yet collecting data on the G. Now we're providing results for every model year, even the 2008.

But more participants would still be helpful--especially for the coupe. The G37 is also included.

To encourage participation, anyone who helps provide the reliability data will have full access to the results free of charge.

For the details, and to sign up to participate:

Vehicle reliability research

Update: the G is also the only model with THREE sample sizes over 100. And the 2003 is at 97--that will be #4. This owner group is awesome.

Hopefully I'll be able to start collecting data on the 2004 and 2005 by next month.

get on this guys!

It takes less then 1 minute!

You'll receive emails with links to the surveys each month.

The first month you're required to respond, and then the month after the end of every quarter (January, April, July, October).

If you have had no repairs, the response is just an approximate odometer reading and verifying that two other pieces of info are still correct. Very quick.

In other months, you just respond if you had a repair the previous month. Then you fill out a longer survey, but it's still just one page:

http://www.truedelta.com/survey.php

The email will contain an encoded link to the survey, so you won't even have to log in. Just click the link and you're there.

That's it. The site has other surveys you can fill out right away, but those are voluntary and are not required to remain a member.

I also send out monthly updates to keep people informed of improvements to the site, but it's also not necessary to read these if you haven't got the tiime.

If you have any other questions, feel free to ask them.

Started collecting data on the 2005, though still a couple short of the minimum. 2004 next closest, six cars short of the minimum.

I've decided that "G35 reliability - how does it truly compare?" may work better.

I'm going to collect data on all but the 2006 this month. The 2004 and 2005 are each still a single car short of the minimum, though. So more cars would help.

Current counts:
2003: 37
2004: 29
2005: 23
2006: 20
2007: 19

Total: 137

For at least 2007, and maybe all years, I'll have to separately analyze the coupe and the sedan. So please keep them coming, as I'll need especially large samples to do this.

We have a sweet young lady here as well now that graces us with her presence every now and again...

Those of you who have signed up--so far this month not enough of you have responded to the survey for me to provide results on any year of the G35. Please respond if you haven't already - this is the survey you receive the emails for.

wait till the light comes on? that means the engine is already loosing oil pressure, right?

Latest counts:

2007: 46
2006: 33
2005: 29
2004: 39
2003: 55

Total: 212

In the results posted this week, only the 2003 is included, and with an asterisk and only visible to logged-in members because of an insufficient number of responses. The stat was 0.5 repair trips per year, which is good but not great for a 2003. First-year of the car, of course.

I didn't have enough responses for the 2007 sedan to include it even in the asterisked results. That said, none of the 17 sedan owners reported a repair, so clearly the 2007 isn't trouble-prone.

The next set of results will be in August. Then I expect to have official results for the 2003 and 2007, and maybe for a few other years. It all depends on how many people sign up and participate.

The hard part with the 2007 is I have to analyze the sedan and coupe separately. It might also be necessary to do the same with other years depending on whether the reported problems are bodystyle-specific. So I might need two good samples per year. In general, most of the above cars are sedans.

If you've been helping out, thanks. If you haven't been, please consider doing so.

2006 G35 6 Speed Manual Premium Package A Factory Sirius Radio 111,221 miles, New brakes @ 85k miles, new 2nd replacement set Bridgestone Turanza tires @99930 miles, New plugs @106.7k miles. No mods required, I love her the way she came. Mod money goes to 401K. Regular 87 Octane, all the time.
Last fillup 3/11/10 24.60 MPG @ $2.51 gal with regular 87 octane.

Have some patience.
My 06 G35 Sedan used 1 qt per 1000 miles when new. It wasn't until i reached 21k miles that my oil consumption dropped to 2000 miles per quart
I believe it is now a little better with over 2000 miles per quart.
I change my own oil using a factory filter every 3k to 3500 miles using Penzoil or Quaker State or whatever is on sale. I think as your vehicle ages you will experience a similar result? I now have 36850 miles. Not only has the oil consumption improved as the vehicle aged so did Gas consumption.
