1991 Pontiac Grand Am

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1991 Grand Am.

The 1991 Pontiac Grand Am is defined by practical engine specifications, such as a 4-quart oil capacity requiring 5W-30 API viscosity, yet its engine and cooling systems anchor the vehicle's 100 total owner complaints and 3 recalls. Within the model's broader 1990-2005 complaint history, this model year sits far closer to the lowest point of 56 complaints in 1990 than to the 909 complaints recorded at the 1999 peak. For researchers, this positions the 1991 Grand Am as a relatively stable entry in the lineup's timeline, representing an early era of comparative reliability before the model experienced a dramatic escalation in reported issues.

From the factory this vehicle uses OE oil filter 12737092. Note the factory fuel filter is now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known.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 engine oil and filter at 7,500 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 1991 Pontiac Grand Am sits near the beginning of a long upward trend in complaints and recalls that peaks around 19992000, with 100 complaints and 3 recalls—a notable jump from 1990’s 56 complaints and 1 recall, but still far below the 253 complaints and 3 recalls of 1992. Technical service bulletins (TSBs) also rose sharply from 1 in 1990 to 8 in 1991, indicating that early issues were already being documented, though this is modest compared to the hundreds of TSBs seen in later years. The top complaint areas for 1991—engine/cooling (28), visibility (12), and hydraulic brakes (10)—are consistent with the broader generation’s focus on powertrain and safety systems, but the data does not specify root causes. Given that 1991 is early in the arc of escalating complaints and recalls, it likely benefits from fewer accumulated design flaws than subsequent model years, but it is not the lowest-risk year in the record. This is a moderately acceptable year to buy if you prioritize lower complaint counts over later models, but the 1990 model appears even more trouble-free based solely on the federal data.
