Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter at 7,500 mi; spark plugs every 60,000 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.

The 1993 Infiniti G20 falls within a period of declining consumer complaints, which dropped from 14 in 1991 to 7 in 1994 before a significant spike to 29 in 1995. With 8 complaints and 37 TSBs, the 1993 model shows a slight improvement in reliability over the 10 complaints recorded in 1992. Recalls remained consistent at 2 per year from 1991 to 1995, and there were no federal investigations for the target year. Complaints for 1993 were primarily centered on Seat Belts and Equipment, though the data does not specify the root causes for these or the single reported instances of engine cooling and fuel system issues. Including one crash and one fire complaint, the overall volume remains low compared to the mid-generation peak. This makes 1993 a good year to buy.
