Replacement part sizes and factory part numbers — battery, bulbs, filters and belts.

From the factory this vehicle uses a BCI 35 · 585 CCA battery, OE oil filter 1520865F0E. Note the factory front wiper blades is now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known. Each part links to every other vehicle that shares it, so a part you already stock may fit more of your fleet than you'd expect.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the spark plugs at 105,000 mi; coolant every 30,000 mi. The big-interval services (every 30,000 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.

Owner complaints about the 2008 Infiniti G37 Coupe lead in one area — the air bags, 12 of 66 reports (18%), well ahead of the next concern. That matters, because the air bags are also the target of recall 08V-521 on this vehicle — so the single most useful check before buying or servicing one is confirming it was actually performed. 2 of the reports describe a crash and 3 a fire — a small share of the total, but worth weighing against the air bags pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
