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 every 100,000 mi; coolant at 150,000 mi. The big-interval services (at 150,000 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 1998 Pontiac Grand Prix sits in a notable transitional period within its generation: complaints dropped sharply from a 1997 peak of 859 to 535, but this remains substantially elevated compared to the early-to-mid-1990s baseline (e.g., 102 complaints in 1996). The 7 recalls and 5 investigations in 1998 are slightly fewer than 1997's 9 and 7 respectively, but represent a higher level of regulatory scrutiny than the 2-4 recalls and 2-3 investigations recorded from 1992-1996. TSBs declined from 110 in 1997 to 72 in 1998, yet this number is still roughly triple the volume of the early 1990s. The top complaint areas—Steering and Exterior Lighting (each 85), followed by Engine & Engine Cooling (77)—suggest persistent structural issues, particularly given the 60 fire-related complaints versus only 19 crash complaints, a ratio that warrants attention. Compared to 1999 and 2000, where complaints continue declining to 413-467, the 1998 model appears to represent the tail end of a high-complaint period rather than a clean baseline. Takeaway: the 1998 Grand Prix is a marginal choice—it benefits from the post-peak complaint decline but still carries elevated recall/investigation counts and concerning fire complaint volume compared to earlier years in the generation; a thorough pre-purchase inspection focusing on steering, lighting, and engine cooling systems is essential.
