Prep Measure the diameter of each cylinder head bolt at point A and point B. Point A = 11.00 mm from thread end and point B = 48.00 mm from thread end. If either diameter is less than 0.18 mm use new bolts coated with clean engine oil. Tighten all bolts to finger tight then continue on with the following procedure.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 7,500 mi; spark plugs at 105,000 mi; coolant at 105,000 mi. The big-interval services (at 105,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

In 2012 the vehicle recorded 12 complaints, a decline from 17 in 2011 but still higher than the single complaint logged in 2005, while recalls and investigations remained at zero. Compared with 2005’s 35 TSBs, the 2012 model shows fewer service bulletins but a comparable number of complaints, with air bags (4) and electrical system issues (2) as the leading complaint areas and one fire complaint reported. No crash complaints were recorded, and the fire complaint represents a small fraction of the total complaints for the year. Given the modest drop from the 2011 spike and the absence of recalls, the 2012 Infiniti G25 remains a reasonable used purchase, though buyers should verify that any air‑bag or electrical concerns have been addressed.
