Infiniti G Reliability

You won't find Infiniti G reliability information like this anywhere else. Actual repair frequencies, not just vague dots. So you can tell how much the Infiniti G truly differs from competing car models in reliability.

These stats are promptly updated four times a year, to much more closely track Infiniti G reliability as the cars age. Others tell you how reliable the Infiniti G was a year ago, when the cars were a year younger and had 12,000 fewer miles on them. Only TrueDelta tells you how reliable the Infiniti G has been recently.

Infiniti G Reliability and Durability: 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
7-speed shiftable automatic RWD
Never had a problem in 25k miles of owning original G35, and reviews of G37 show similar results.
2008 4dr Sedan 306-horsepower 3.5L V6
5-speed shiftable automatic AWD
Infiniti sedans have been reliable and a major reason I purchased it.
2008 4dr Sedan 306-horsepower 3.5L V6

I have now owned 4 Infinitis. THey are well made
2008 4dr Sedan 306-horsepower 3.5L V6

Reliability was listed as above average and have owned other Nissan products that were reliable.
2008 4dr Sedan 306-horsepower 3.5L V6

Replaced all 4 wheel bearings in one year :( Not sure what this would be from. Went to dealer to ask and they didn't have any TSB's on it. Not uncommon to have one go - but not all 4 in abou 5 mos. Suspect a local repair shop over torqued wheels - but no proof.
2008 2dr Coupe 330-horsepower 3.7L V6
6-speed manual RWD
very reliable

Good reputation

It has been in the shop for warranty work 2 times already.

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.

aforementioned wheel bearing issues.

CU rated the G35 less than the Honda Accord in this area
2003 4dr Sedan 260-horsepower 3.5L V6

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
