Infiniti G Reliability through December 31, 2012

An asterisk (*) marks results based on small sample sizes.

General NotesModels and statistics marked with an asterisk (*) have very low sample sizes. These results, visible only to logged-in members, provide only a rough estimate of car reliability.

Any result under 20 repair trips per 100 cars is likely a result of the small sample size, and should be expected to increase to 20 or so in future updates.

New models often start out with high repair rates, and then improve as the manufacturer identifies and addresses common problems. MethodologyOnly successfully completed repairs are currently included in the analysis. Routine maintenance, most wear items, recalls, and problems fixed with just a reflash or warning light reset are not included.

What Our Members Are Saying about Infiniti G Reliability and Durability

Reliability and Durability of the Infiniti G: Pros
YearBody/PowertrainComment
2010 4dr Sedan 328-horsepower 3.7L V6
7-speed shiftable automatic RWD		 Despite the high-performance, the G is rated above-average, same as our G35 - which has only been in for routine maintenance (and a couple of recalls). The old G35 only parts needing replacements in 7 years were the two clock bulbs.
2009 4dr Sedan 328-horsepower 3.7L V6
7-speed shiftable automatic AWD		 39 months with no repairs.
2009 4dr Sedan 328-horsepower 3.7L V6

5-speed shiftable automatic AWD		 Online and editor reviews as well as owners comments on websites show the car to be very reliable and seldom has major service issues compared to its competitors
2006 2dr Coupe 280-horsepower 3.5L V6
5-speed shiftable automatic RWD		 Reliability is great as engineering is top notch. The VQ motor can go 250,000 miles no problem under routine maintenance.
2006 4dr Sedan 280-horsepower 3.5L V6
5-speed shiftable automatic AWD		 No major problems in 24 months

2006 2dr Coupe 280-horsepower 3.5L V6
5-speed shiftable automatic RWD		 I love the reliability so far. At 122,000 miles, all the switchgear functions beautifully and shows no wear & tear at all. There are no creaks or rattles in the dashboard or center console.
2006 4dr Sedan 298-horsepower 3.5L V6
6-speed manual RWD		 I have no worries about my car breaking down.
2005 2dr Coupe 298-horsepower 3.5L V6

2005 4dr Sedan 280-horsepower 3.5L V6
5-speed shiftable automatic AWD		 Pretty reliable on a whole
2005 4dr Sedan 280-horsepower 3.5L V6
5-speed shiftable automatic AWD		 Nissan/Infiniti engines will last a very long time, and this car has an excellent history of reliability.
2005 4dr Sedan 280-horsepower 3.5L V6
5-speed shiftable automatic AWD		 After 22K miles (now at 35K), no major expenses other than front rotors and new tires. Engine is strong, interior and ecxterior in great shape.
2004 4dr Sedan 260-horsepower 3.5L V6
6-speed manual RWD		 Everything works - and continues to work - well. Routine maintenance is relatively easy and I expect to see 150-200K miles on this sedan.
2004 4dr Sedan 260-horsepower 3.5L V6

5-speed shiftable automatic AWD		 reliabile car
2004 4dr Sedan 260-horsepower 3.5L V6
5-speed shiftable automatic RWD		 minimal repairs in 3 years of post-warranty ownership.
2004 4dr Sedan 280-horsepower 3.5L V6
6-speed manual RWD		 G35 is not perfect but you will have to look pretty long and hard to find unhappy owners. These cars use a number of proven parts from the Nissan bin including the VQ engine which is nearly bulletproof. Repairs when they do occur are quite reasonable
2004 2dr Coupe 280-horsepower 3.5L V6
5-speed shiftable automatic RWD		 Only 1 warranty repair (minor annoyance), no other unplanned time in the shop.
2004 2dr Coupe 260-horsepower 3.5L V6
6-speed manual RWD		 Nissan and infiniti are known for excellent reliability, although there have been minor issues I have experienced the overall mechanical components of the car have been terrific.
2004 4dr Sedan 260-horsepower 3.5L V6
5-speed shiftable automatic AWD		 Very few issues, and nothing major has occured in 60,000 miles.
2004 4dr Sedan 260-horsepower 3.5L V6
5-speed shiftable automatic AWD		 The VQ is a proven engine. I have had no problems to date and expect it to last a very long time.
2003 2dr Coupe 260-horsepower 3.5L V6
5-speed shiftable automatic RWD		 In 53K miles only service required has been routine: oil service, air filter, coolant replacement, accessory drive belts. Brakes and tires have required replacement early, but that may be expected on high performance GT coupe. Car drives like new.
2003 2dr Coupe 280-horsepower 3.5L V6
5-speed shiftable automatic RWD		 not much maintenance
2003 4dr Sedan 260-horsepower 3.5L V6

Reliability and Durability of the Infiniti G: Cons
YearBody/PowertrainComment
2008 2dr Coupe 330-horsepower 3.7L V6
5-speed shiftable automatic RWD		 Within my two year lease of my vehicle it has been brought it countless times for repair. Exhaust on the car was faulty and needed to be replaced twice. Apparently something was wrong with the resonators and it made a hideous metal pinging noise.
2008 4dr Sedan 306-horsepower 3.5L V6
5-speed shiftable automatic RWD		 It has been in the shop for warranty work 2 times already.
2005 2dr Coupe 298-horsepower 3.5L V6
6-speed manual RWD		 CU rated the G35 less than the Honda Accord in this area
2003 4dr Sedan 260-horsepower 3.5L V6
5-speed shiftable automatic RWD		 Brakes, stereo, electrical system, seats, wipers etc have required more frequent repair than expected. In some cases you have no choice but to replace the defective component with a stock part which again fails after a similar length of time, kind of a vi
