Maybe it won't be a G37 Sedan Z. But I've heard that the next production version of the G37 will be TWIN TURBO/ AWD with 500HP under the hood. Price will be double what it is now. I think I read it from some automobile magazine but can not remember.
Being a new model, it took three weeks to get a replacement.
It has resolved the issues and the service advisor said other G37's were coming back with similar issues.
FYI... If you experience this, you must have XM radio flash your new radio ID which can be found on channel 1.
I live in Plano, TX. I have decided to go with the G37 Journey, Red/Graphite, w/ Premium Pkg & NAV. My question is do buy now, an 08, or wait for the 09. How can I find out what, if any, changes there will be with the 09 including price? Thanks in advance for any help.
I got black G37 few months back... met with small incident . ended up to replace with a new fender.
Does replacing fender involve paint job? Is it factory paint or custom paint? Can't I get fender with color from factory?

Granted, I don't drive aggressively, but I don't just cruise either. Unless you are driving it at or near its full potential, I don't know why your mileage is so poor.
Maybe the retailer's service department can give it a once over and find something for you.
Good luck.

Anyway, these numbers are the pencil and paper real deal. Surprisingly close to the trip computer calculations.

When traveling, I usually look for Exxon/Mobil.
Don't know much about the tires. I am not at that point yet. However, I probably will look toward Michelins when that time comes.
-Steven
BTW, totally agree that Michelin builds a superb tire, but will cost you more. Only you can determine if they provide the value & performance you need. Again, Tire Rack can provide excellent insight.

I ended up going with Michelin Pilot Sport A/S, 245/40-19 front, and 255/40-19 rear. They are each about +1 size over the OE tires, but fit just fine (10 mm is about 1/3 of an inch more tread width). I have used the Michelin's on several cars in the past, I think it is an outstanding tire. The dry weather performance sacrifices very little to pure "summer only" tires, you will not notice a difference unless you autocross the car. They have a big advantage of not only allowing driving in light snow and slush, but superb rain/wet weather performance (which the OE Bridgestone's are not good in).
Good luck!
All you need is a good winter tires.
There is variable valve timing for intake and exhaust valves. The exhaust valves are adjusted by an electric motor. The intake valves are adjusted internally from oil pressure.
If you cycle the key(turn it off and restart), the noise goes away for a few seconds. then the engine goes back to its original state and somehow does not transmit the excessive noise.
The fix is something called ESTER oil. It comes as the OEM oil from Japan. This oil accommodates the intake valve lub specs. Internally, no one told Infiniti to use ONLY this oil for oil changes in the 3.7 engine.
I was assured by the territory (factory) rep no harm has been done to my engine, and my retailer has learned something as well.
Mine does, then it settles down. Has done this since the day I picked it up.

I get one as a loaner during service, and it carries everyone with room to spare.
Infiniti has a technical bulletin addressing this. Apparently "ester" oil was shipped in the vehicles from the factory, but at the 1st oil change after purchase, non-ester oil was used. Hense the valvetrain noise. The problem was identified and the the fix was the reintroduction of ester oil.
Happy motoring.
congrats on your new car it looks great. can you tell me if the 09 trunk has an obstructed trunk opening due to the nav/cd system? i know the 08's did and it made a small trunk even smaller. what did you end up paying? i'm sure there not offering the 0.9 financing like the 08's have.
thanks

Let's clear up a few things here. The Nissan Ester oil is NOT a synthetic blend. It is conventional 5W-30 oil. According to the European Patent Application for this oil available on the web and referred to in a number of other G37 forums, the claims for this oil are that the carbon-based additives increase fuel economy. According to the Infiniti VVEL Technical paper, the carbon-based additives reduce friction across the VVEL valve stem diamond-like carbon coating. That seems to be the gist of the Nissan Ester oil.
Esters are PAO based substances added to oils and lubricants. Based on the European Patent Application, the Nissan Ester oil does not seem to have additional esters or greater quantities of esters.
Are you referring to the "out-of-sync" VVEL Technical Service Bulletin? If so, the newer software seems to be the key to getting the VVEL to return to idle, even though the amended TSB calls for an Ester oil change after updating the software.
Nissan has only recently stated the Ester oil is a factory fill. Most people with Ester factory fill may not have even performed their first oil change yet. The "change" from Ester to non-Ester oils does not appear to have any effect on the valve train noise you refer to. And, I am not sure what noise, exactly, you are referring to. The "identified" problem is the VVEL software which does not return the valve timing to idle setting after the car has been driven hard. The updated software is the "cure" for the out-of-sync VVEL knocking. Unless a different "noise" could be caused by the valve stem diamond-like coating, and the Ester carbon-based additive is the only way to the quiet this noise, then the cure is not the Ester oil.
This information is all available elsewhere on the net.
Has your G37 been updated with the software referred to?
I am using Mobil 1 synthetic. From what I have read this oil does have the Ester properties.
Thanks for the additional material.
(The Bluetooth site at Infiniti indicates it is being tested but makes no recommendations pro or con.)
You could use any MP3 player via the aux input, but you wouldn't have control over the songs/menu the same way you do with the iPod.
How is your sound clarity?
There are many posts on Pre related websites that would indicate that poor sound quality is to be expected and is being broadly experienced.
Also, based on historical evidence do you think the new models will cost more or will they about the same? And will the 2009 models be cheaper once the 2010 models have been launched?
Thanks
If you do decide to return it let me know and I will not torment you by advising you when the next software mod comes down the line and fixes the problem.
