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. full 2010 Infiniti G review

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. full 2008 Infiniti G review

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 full 2003 Infiniti G review
