infinity g37 reliability

Infiniti G-37 is a great vehicle. See if you can find one with a service history and a warranty. We owned a 2009, bought it new and drove it 5 years without any issues what so ever. Make sure to change the oil every 5,000 miles or less and only use synthetic oil. The valve train in these cars is picky about oil.

While not an unreliable car, the G37 will cost you more than an Altima or Maxima when it does go in for service.

Despite being Boston's TheSubaruGuru for decades, I've provided an '09 and now last-of-production '13 G37xS for my wife as a no- brainer ultrareliable alternative to an Audi A/S4 or BMW 3 Series...or MB E. In both cases NOTHING EVER needs attention. Yet TheHorror is correct in that eventually rust will take apart the fancy dual exhaust. The extensive use of aluminum under there, as well robust suspension parts and sturdy wheel bearings has meant easy ownership. Mediocre fuel economy is the price paid for this ultra-reliability...and despite all the tricks I've tried with the fatter coupe's rear swaybar, staggered wheels and tires, ya just can't escape the G's stiff and numb initial turn-in. Anyone know how to eliminate that initial understeer? But once a turn is started the dynamics are excellent (with the fatter rear swaybar). The G37 definitely rewards the use of better tires on 18" wheels. The OE (non-S) 17" w/ 225/55R17 are just too sloppy for the G's mass at higher g forces. The 18" OE size is 225/50R18 all around for the AWD X, but, again one can put 245/45R18 on the REAR (only) to improve handling...even with the X AWD (the 1.5% error rotation F-to-R is less than the ATTESA AWD brain's 5% slip threshold for adding FWD traction. Works great. Many will tell you they run the G37 on regular or mid-grade fuel, but at these cheap oil prices I've used premium throughout. But a cheap trick would be to alternate 93 and 87 to get the 91 it wants, as octane isn't a linear scale, and half 87 and 93 equals 91, not 90. But I prevaricate.... The audio system is terrific...and is one of BOSE's great iterations; but even the OE is very nice. Folks complain about the higher rpm roughness of this older motor...and its torque buildup is linear rather than punchy, so ya gotta push it a bit for passing at high speed, but i prefer that to the crazy on-throttle lag of Audi's modern high output 2.0 turbos, for example...especially in urban dynamics. I have the option every week or so to grab a Legacy Limited 3.6 as a comparison, but the G is simply much better built. Yet fuel eco may someday result in powering down to a Legacy Limited 2.5i for its stupendous fuel eco (32+ hwy on 87 vs 26 hwy on 93). Lastly, don't bother with the aftermarket dual cold air intake systems for the already-twinned G37. They don't do anything except add a bit of on-throttle burble. I tried the beautiful Fujita system, but there's absolutely no benefit. Just get the OE Coupe's fatter rear sway and 18" wheels nice tires and enjoy.

Sorry for the verbal diarrhea.... You may wonder if the S model is worth much more. Yes, it gets you the 18" wheels so you run 225/50 all around, but also includes sportier buckets with thigh extension, and importantly for my short wife and I, pushbutton seat memory, allowing me to stretch the seat downward and rearward without all the fine-tuning I'd have to do each time with the previous G37. So I think the S is worth the extra $1k. Just don't forget that cheap $150 for the OE coupe's rear swaybar....

I agree with almost all posted by TheSubaruGuru except for his audio system comments. The audio system in our 2009 G-37x sedan was Bose and it was crap. There is a reason they say "no highs no lows it must be a Bose". The G37 IS a great car period.

Hi Bob. Interesting, as in my early audiophilic years we labeled Bose HOME satellite systems as all top and bottom, with almost a missing octave in the midrange. Interesting story: when Amar Bose first heard Bose engineers' first 3-way sub-sat system he complained that the satellites were too big, and demanded they be smaller for better WAF (wife acceptance factor). The engineers balked, as a small mid-tweet would leave that infamous "hole-in- the-middle" that they became famous for. I have friends who still have these anemic systems in their secondary rooms (like kitchens and bedrooms), and I simply can't stay in the room when they're playing because of the sizzly-hot top. It's pretty damned hard to get a midrange smaller then about 100mm diameter to reproduce the human voice really well. Can't remember if our '09 had OE or Bose, but I remember that it was EQ'd pretty well. Regardless, the '13 Bose is terrific, unlike the really crap job they did in my Miata...but that may have been a winless task. But their paper 3" mid-tweet is a fifty-cent crap driver. Bose is/was famous for shaving pennies on drivers because they bought so many back in the day.

Best factory sound I have ever heard was in our 2005 Acura TL with their ELS sound system. It was fabulous and far better than the THX 14 speaker sound system in our 2014 Lincoln MKZ.

The Bose Studio On Wheels is fabulous in my 2009 G37. Most of you only have the standard stereo. Massive, balanced output.

Hey GQ et al, After deciding NOT to get a modern Q50 3.0T, mainly because of the weird steering and unobtainium proper options pkg, I treated our '13 G37x to an CAI and front strut brace for cheap kicks. The slight burble MIGHT indicate the +12 ft-lb grunt Injen promises, but the Magus brace is just jewelry, of course. It's been my wife's ultrareliable chariot, and now she's hankering for a 5th door, so one of TheSubaruGuru's OBs may get her license plate soon. The HK audio is very well done, although natively balanced a bit forward, which is easy to adjust. Just wish the seats were as comfy as the G's. Hard to argue 26mpg reg vs 21mpg prem though.

So I put our Graphite/Wheat 2013 G37xS, 53k (yeah, all Trader Joe's, Market Basket, Wilson's Farms and the ladies' health club) up on local Craig's in the $15k's, hoping no one buys it yet. I even treated it staggered extra wheels (works just fine w/ ATTESA) and of course the stiffer rear anti-swaybar from the Coupe. The only attractions for replacement are too new to afford ('19 Genesis G70 or '19 3 Series) until used in a year or three, and I'm no longer enamored of Audi's motor-forward geometry and lack of road feel. What's an old fart to do while his Cosworth'ed Miata hibernates? I'm not quite dying to part with our G37 by pushing it here on CG....

I reread my post here re CAI from a year ago. The Injen CAI design is really clever, and the combined effect of a bit more mid-throttle intake sound and POSSIBLY-FELT (yay, placebo effect!) of that +12 ft-lbs torque is kinda fun...but maybe not worth Injen's list price. But I respect the effort.

I have a 2011 G37S, has 254000 miles and never been in the shop. Still going strong

I'll be testing a couple of off-lease Q50 3.0t Sports 2016+ as they appear at Nissan's auctions later this summer, but the weirdness of the DAS has me pining for a G30 3.3t AWD instead. Sold my '13 G37xS last week. I miss her already, but it's Miata time here in Beantown.

@thesubaruguru would you still buy a 2011 G37xs sedan with 90k miles? In good shape no major changes besides oil changes and runs good. Good mechanical conditioner. Minor scratches but fixable. I have a friend selling one and I am debating if it’s worth it. He wants 13,600 for it.

It's 10 years old. Condition is everything. If in the rust bely inspect carefully the fancy twin exhaust for possibly pricey replacement. Add the coupe's fatter rear swaybar while you're at it, if purchased. Otherwise the normal brakes, tires affect sale price. A relative gas hog by modern standards, but still one of my favorite AWD sedans of all time. Drop dead reliable.
