Overview & Reviews

Originally, Infiniti's G sedan was not much more than a humble, rebadged Nissan that got some leather trim and a few extra features to become an Infiniti. It wasn't a convincing luxury car and it was indicative of a brand that didn't know what it was.

Then the G35 came along and not only did Infiniti now have an entry-level model that could take on the world's finest luxury sport sedans, it had a basis for which to establish its brand identity. A fun-to-drive personality, ample high-tech features, eye-catching styling and attractive pricing mark the Infiniti G sedan. As such, it ranks among the best choices in the segment and its long-standing popularity ensures plenty of good prospects for savvy used car shoppers.

Note that this model could potentially carry on with a new name, Q40, in the near future.

Used Infiniti G Sedan Models
The last-generation Infiniti G sedan (the fourth generation) was produced from 2007 through 2013. At first, it was only available as the G35. It then featured a 3.5-liter 306-horsepower V6, usually paired to a five-speed automatic. Trim levels consisted of base, Journey, x (AWD), Sport and Sport 6MT (six-speed manual). We found the latter transmission disappointing, as it was unrefined and sometimes difficult to drive smoothly. Rear-wheel drive was standard, while all-wheel drive was available and indicated with an "x".

The G37 and its accompanying 3.7-liter, 328-hp V6 debuted for 2009, as did a seven-speed automatic that was standard equipment on all but the Sport. The latter again came with a six-speed manual transmission. The following year brought subtle styling tweaks and some new navigation features. Although rare, some G sedans made between 2007 and '09 may have a then-optional four-wheel active steer system (4WAS). Reactions were mixed, though, with several drivers noting diminished steering feedback in so-equipped vehicles.

For 2011, the G25 debuted, offering a less-expensive, lesser-equipped entry into the G family. Produced just two years, the G25 had a 2.5-liter, 218-hp V6 mated to a seven-speed automatic transmission. Buyers had a choice between standard rear-wheel drive and optional all-wheel drive (G25x).

Standard features highlights typically included bi-xenon headlights, keyless ignition and entry, Bluetooth connectivity, power front seats, leather upholstery, heated front seats and automatic climate control. As the years went on, more standard features, such as an iPod/USB audio interface and a rearview camera, were added. Sport trims featured a limited-slip differential, unique 18-inch wheels, summer tires, a sport-tuned suspension, bigger brakes, sport seats and design flourishes. Option highlights included a sunroof, rear parking sensors, a Bose stereo and a navigation system.

Inside the cabin the G boasted user-friendly controls, excellent build quality and a handsome design -- the latter highlighted by such items as the car's leather-accented magnesium transmission paddle shifters and Japanese "Shodo-brushstroke finish" aluminum trim (wood trim is optional). The front seats were comfortable and well-bolstered, and the available sport-styled seats offered even more aggressive bolstering, though they could be a bit too snug for larger drivers.

In reviews we found the Infiniti G sedan a well-balanced luxury sport sedan. Although there are plenty of creature comforts, it's the G's dynamic demeanor that has made it a standout among driving enthusiasts. Think of it as a world-class athlete in formal wear. The G's handling was praiseworthy, as it attacked curves with aggression and precision, yet remained poised and compliant when driven over broken pavement. Furthermore, the G37's rapid acceleration was rarely bested in this class.

Overall, any fourth-generation Infiniti G sedan stands shoulder to shoulder with anything in the entry-level luxury segment. Used car shoppers in the market for such a vehicle would be wise to put it at the top of their to-drive list.

The third-generation Infiniti G Sedan was introduced as the G35 and was produced from 2003-'06. It looked similar to its successor, but was more angular and, more notably, had a less luxurious interior with lower-quality materials. A less powerful V6, different chassis tuning and a less stiff structure also make it a less advanced driver's car, but for the time, it was tough to beat and a true performance bargain.

Originally, the G35 was available in one trim level until the all-wheel-drive model arrived for 2004. Its 3.5-liter V6 initially produced 260 hp, but it was bumped to 280 for '05. If you got the manual transmission, it got pumped up to 298. It should be noted, however, that G35s produced for '07 and later have slightly lower horsepower figures, but this was due to a change in SAE testing procedures -- actual output did not change.

Other than the myriad engine changes, there were other noteworthy updates made during this G35's lifetime. It received a new hood, grille, bumpers, side sills and taillights for '05, although it was hardly a revolutionary aesthetic difference. Inside, though, it benefited from a redesigned instrument panel and improved manual transmission with a lower shifting effort. Bluetooth arrived on all Gs for 2006.

In our reviews, we were quite fond of the third-generation Infiniti G. The sedan was a bargain-priced and roomier alternative to the BMW 3 Series. If there was one area of concern, it was the cabin's use of some cheap plastic trim and some unintuitive controls. One feature that was welcome, though, was the optional reclining rear seatbacks, which made it a top choice for backseat comfort.

The first- and second-generation Infiniti G Sedans sold in the 1990s were completely different animals than the subsequent rear-wheel-drive, high-performance breed. These compact, front-wheel-drive models dubbed G20 were unimpressive rebadged Japanese-market Nissans and were produced at a time when Infiniti hadn't established its current knack for creating fun-to-drive, value-oriented luxury sedans.

  My second G - 2013 Infiniti G Sedan
  By slonedigitty - October 12 - 10:06 am

  This is the second G Sedan X that I have owned. My first was an 07 G35X and I loved it! I just traded it in and got an 13 G35X. You wont regret the decision of buying this car. Great price backed up by reliability and great customer service. I didnt have one problem with my first G and it had 68,000 miles on it when I traded her in. My only issue would be that the interior and exterior styling hasnt changed very much even in 6 years! But, I guess you dont wanna mess with success. And as far as performance goes, you will not be disappointed. With an avg of 20mpg and 0-60 in the low 5.0 range you cant lose. And lastly, the Bose system and interface is amazing.

  Rattles, lack of interior storage - 2011 Infiniti G Sedan
  By hmkxi - September 25 - 2:16 pm

  Bought September 2010, now has less than 4000 miles on it. Everything is fine except the rattles from the rear window area. I took it to the dealership once, but nothing has been solved. The rattles are not too bad, but still, it is definitely something prevents me from enjoying this car. Dont know whether another people have this problem or I am just unfortunate. Also, the interior storage is kinda insufficient. Overall, the rattles really ruins my confidence in buying another infiniti.

  An Oldie but Goodie - 2013 Infiniti G Sedan
  By Mike H. - April 12 - 6:14 am

  I purchased this 2013 Infinity G37x used with 29,000 miles. It is one of the best cars Ive ever owned. This car is everything the other reviewers have positively stated. This vehicle is classified as "near-luxury" and lives up to this. Nice power from the 3.7L engine, smooth transmission, great ride, exceptional interior materials, very logical controls and nice interior displays. Handling and braking are exceptional also. This vehicle does use premium gas, but with everything said, I found this not to be a negative. This is one great car!

  Great Car - 2012 Infiniti G Sedan
  By robflo22 - September 28 - 5:51 am

  Ive had this car for a few months and am very happy with it. Coming from a 2009 Maxima 3.5 SV, it is definitely a step down in power, but the engine is powerful and provides adequate horsepower to still make the car a fun drive. Still a good amount of engine roar when accelerating. Not a fan of the 7speed transmission; would perform much better with a CVT like the Maxima has. The drivers seat is also very small, I am only 59 and I feel like a giant sometimes, the car needs a thigh extender on the seat. The steering is very tight which is great to give the car a sportier feel. Gas mileage is about 22-24 mostly highway, will be lower once AWD kicks in. Nice alternative to G37!!

  A muscle car in a slightly-upgraded clothing - 2013 Infiniti G Sedan
  By between3and14 - August 19 - 2:20 pm

  I got this G37 RWD Journey to inject some fun in my family car/ 100 miles/day commute routine. It delivered mostly with its responsive engine, communicative steering and pretty stiff but competent suspension. I have a slight issue with the automanual though - it is supposed to have the rev-matching feature but so far it seems to over-rev quite a bit - so the car surges forward on downshifts (3->2 especially). The seats are nicely shaped but somewhat hard on the bottom - the heater element might be the cause. Anything in the front cupholders seems to get in the way of operating the gearshift stick. The maintenance alert system relies on simple mileage and does not monitor oil/engine state.

  Confident: G37 Sedan is Definitely a great purchase! - 2011 Infiniti G Sedan
  By johnx2011g37 - August 13 - 2:50 am

  Before making my decision on G37 Sedan, I carefully researched BMW 335i, Audi A4, Lexus IS350, the G37 Coupe (330HP). My pricing range is in between 35K - 45K. After test drove all these cars, I have to choose G37 sedan because its a mix of quality and stylish and power. Most importantly, you could feel the car has built very solid, the engine makes you feel powerful, and confident on the street. While 335i has twin turbo but unfortunely tons of problems. Both A4 and IS350 lack of power. The G37 Coupe version is nice, but its a bit heavier than the Sedan. also only 2 HP more than the sedan, I would recommend you getting Sedan not only I have one, but its a better value by far.

  Big huge mistake...dont you make it too - 2011 Infiniti G Sedan
  By edsets - January 13 - 1:40 pm

  After I went I took the car in for a slipping transmission. Was told the car needed to be broken in and to come back in a few months. I went back in 3,500 miles. The car will sometimes search for the gear it needs. Not safe when youre on the highway and attempting to pass another vehicle. This car has the potential to leave you hanging for several seconds while it searches and eventually engages. The dealer acknowledged that this transmission is suited for a 5 or 6 speed, not a 7 but that the car does perform according to how it was built. I asked if it would take people getting hurt to get Infinity to address the problem and was told, "yes"

  G37x - 2013 Infiniti G Sedan
  By mlbm001 - November 17 - 8:33 am

  I really like the car, but the ride is firm and road noise is noticeable on less than perfect roads. Infiniti will need to up their game on technology features on the next generation Q50.

  Glad I bought the G37 - 2011 Infiniti G Sedan
  By wde - November 16 - 12:55 pm

  Ive been looking at cars off and on for a few months and the G37, Volvo S60, Maxima, and Genesis were on the list. Genesis was too large and I wasnt sold on the CVT in the Maxima. After driving the S60 and G37 back-to-back, I went with the G with the Premium package. Handling was a little sharper than the S60 and power is effortless. Plenty of features. The car is fun to drive. The ride is firm and on the sporty side, so if you want a softer ride, look at a Lexus. A G wants to be driven but will provide plenty of creature comforts at the same time.

  Hot Rod Luxury Car - 2011 Infiniti G Sedan
  By les55 - July 5 - 7:52 am

  Owned a week and this car is hot! Heads turn when its on the road. 26 MPG out of the box! A/C cools it down quickly--you need that on the Gulf Coast.
