Since the G37 doesn't come in AWD I bought the Audi A5. Coming off an M35x lease, I wanted a little sportier car but without the AWD in New Jersey, I went elsewhere.
Hi all, 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.
My G37 developed issues with the hard drive that operates the GUI for Nav/Radio/Heat&Air/Reverse monitor. Infiniti determined the entire unit needed to be replaced.
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.
There's not much else you can do except wait for the 09s to arrive in the dealerships. That way you can try both first and make a much more informed decision.
I did hear from a salesperson at local dealership that an AWD G37 will be offered in 09, available late summer. Haven't picked up any other info or details, tho.
I would like the wheat interior to be an option on the 6mt sport model. Not sure why it isn't for 08, but have asked my dealer to see if it will be for the 09 models.
i purchased my black g37 fresh off the boat in sept. and now have 27,600 miles on the original tires. this is much longer than i had expected the tires to last on the rough asphalt of rural tennessee.i get the oil changed at the dealership every 6 weeks. tire tread is now at 4 mm, road noise is getting to be a problem however. i have two questions for the group: 1) should i replace tires now because of noise and 2) anyone have more miles than this ?

Hi my name is Steven, I have a 2008 g37 Coupe, awesome car, but the gas mileage sucks. Now I know that gas prices are high, no, CRAZY!!! I just wish that it did better than 16-mpg. When I hit the "Status Button" that's what it said. I know its got a big engine, with alot of horsepower, but give me a least 20-mpg. This thing is costing me about $75.00 to fill up. For a Japaneese car it should do a little better, otherwise the car is cool, and I do love the sound of the engine and the duel exaust. I get alot of compliments, other people also seem to like it. Are any other owners experiencing such fantastic gas mileage, please let me know. Thanks. -Steven
Hi Steven. I bought my `08 G37 last Christmas. It currently has approximately 8700 miles on it. Most of my driving is around town and I get 20+ mpg. We just returned from a 600 mile trip (averaging 80mph), and recorded 23+ mpg.
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.
Hi,thanks for the reply. This 20-mpg that your getting, do you know this information because of the "Status Botton" on the center dash, or is this calculated? I know that the window sticker said 17-22. Thanks. -Steven
My g37 ipod adapter is not charging my new 3g iphone, it used to charge last years' iphone. Anybody with similar problem and how do i solve it?, external car charger will not do,since it beats the purpose of the intregrated ipod system.
Thanks for the reply, I'm going to try a different brand of gas. I was told that a better quality of fuel might help to increase my mileage. I didn't know this, I've been using WAWA Gas. I'm hoping that after I switch to Sunoco or Shell, I'll do better. What brand of gas do you use in your G? Thanks Again. -Steven
Here in metro Atlanta/North Georgia, I use Racetrac premium (93 octane). While not a "major" brand, it is offered all over our area, and it gets the job done. My retailer told me as long as I use a premium w/detergents, everything will be fine.
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.
I wish my G37S had a little less horsepower and more torque. I would probably get better gas mileage. More torque would be nicer "off the line". I have to get to 4000rpm before a nice kick, I can appreciate it's a luxury brand, but more torque!!! The horsepower @ 315 would be fine, that's still very fast, and increase the torque to 300 foot lbs. up from 270. Just a thought, thanks. -Steven
I've used Pirelli PZero Nero A/S's as well as summer's on my BMW (530SP). Also Dunlop SP Sport2000 A/S's. I have found the Pirelli's to provide a good balance of grip in all conditions with decent wear/noise characteristics - having switched to the A/S's to squeeze some additional mileage out of a set of tires. Believe there is a price/performance ratio to be considered, so look into doing some research on Tire Rack and using that info to negotiate with your local performance wheel/tire retailer. My guys in Atlanta are superb.
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.
Same here, Apple disabled the 12V/Firewire old way of charging starting with the 3G Iphone. Now it will only charge with 5V USB power. I contacted my dealer about some kind of a solution and waiting to hear back from them. In the mean time there is an adapter that Kensington makes with USB charging and Dock pass though that according to the apple forums will do the job.
Nice car, I just got one in black, they're MEAN!!! I'm affraid to race anyone, I finally cleared all of the points off of my license, don't want to mess it up yet. It's hard to resist the power. Best of luck. -Steven
I have a G37S, and searched exhaustively for all-season tire options. Unfortunately, there are very few, and none in the exact OE sizes for the 19 in wheels of the S.
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).
I would not have bought a G37S if it were my only car to use for winter driving. If you want all season driving consider a model with AWD. The G37 is engineered to be a sports car not a winter driver. When the roads ice up here in WA state, I’ll leave the G37 in the garage and drive the AWD vehicle. On another note: I have owned the G37S with auto trans and all options less the tech package for about six months. The only complaints are: annoying rattles that come and go-like the vanity mirrors and the sunglass box, the tranny shifts into high gear at very low speeds, and the display does not display what gear the tranny is in when shifted to manual shift. The car wants and is engineered to be driven fast and exceeds my expectations when pushing the limits. The Sport model has a very firm ride, as it should be, don’t purchase it if you want a cushy ride.
I noticed an unusual noise coming from the engine several weeks ago. I took the car to my retailor who researched the problem and found the 3.7 engine has a different technology from other Infiniti engines besides the obvious.
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.
Does your 2008 G37 idle rough for about the first 30 seconds after it has sat overnight? Mine does, then it settles down. Has done this since the day I picked it up.
No. The cold idle is fine. A little fast but it does settle down after several minutes on the road. It was suggested cold idle, and other throttle issues would be affected by this ESTER oil issue.
When you first start the car, it has that heavy rumble. That is normal, my g37s does the same. The car is very cool... I just have to try not to get any tickets. Good luck with your car, you should'nt have any problems. -Steven
The back seat of the coupe is very tight. Our granddaughters (all under 5 yrs) are cramped back there. As your kids will only grow larger, I highly recommend the sedan.
I get one as a loaner during service, and it carries everyone with room to spare.
I had the same problem at start-up when cold (lower than 50 degrees or so outside temp). The noise is almost like when you have just change the oil in your car, everything drained, and the car is filled with new oil. It had that clicking noise, valve-tap almost. I called the dealer and they also mention an oil change with Ester oil, for free (only the first time I supposed?!).
The noise was definately from the valvetrain, and was at random. Ester oil corrected the problem immediately with no further occurance (1500+ miles). Yes, the first Ester oil change was free, but I own the rest of them.
Ester refers to a synthetic blend of oil that has certain high end lubrication properties. Don't know where the name "Ester" came from.
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.
hi, 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.
Thanks for the great response. 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.
Wow. Talk about information overload. That which I presented came from the retailer. However, your feedback is more plausible. I will check with the service advisor to see if he is aware of what you have revealed here.
I have the Palm Centro, which probably has a similar Bluetooth interface to the Pre (but I'm not certain). It works fine, but the biggest problem is that it cannot answer calls. (It recognizes when the phone rings and appears to let you pick up, but the call gets dropped; if you answer directly on the phone, however, it works fine.) It also doesn't display the number/ID of the caller, which is all the more reason to pick up your phone and look. It's not perfect, but the hands-free operation otherwise works well (much better voice quality than on the Acura TL, from my experience).
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.
Well, I got the Palm Pre and not only does it work, but I can answer calls and the caller i.d. comes through :surprise: . The only thing it didn't do was automatically download the phonebook . That had to be done manually.
Mine works too however the sound is scratchy and not as clear as my previous Samsung. 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.
Does anyone know when the 2010 models will be launched and when they will actually be available?
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?
I think the main reason they tune these VQs that way is to reduce stress on the drivetrain. Going from 270 to 300 tq would probably require an upgrade to the drivetrain while high RPM horsepower doesn't. Still, we're not suffering here like a Honda VTEC motor used to be! In a couple years I think the direct injection may help a little bit with a bit more power but not sure. Although, I bet the automatic isn't the problem, it's probably having more torque would over stress the clutch and shafts so they tune it for higher RPM, just my 2 cents. :shades:
The more I'm using the Palm Pre in the Infiniti, the more I am intending to agree with you. In fact, I may have to take advantage of the Sprint 30 day trial period and relinquish it.
I know I've considered giving my Pre back as well but decided not to as I really like the phone. If it didn't work at all well then maybe but I can tolerate the imperfect sound in the Infiniti rather than give the phone up totally. It would be even better to lead a REAL life and not worry about crap like this. 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.

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?
