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; 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 Acura Integra sits near the peak of the generation's complaint and investigation activity, with 40 complaints and 3 investigations—the highest investigation count across the entire dataset (tied with only 2023-2024 for later model years). Compared to 1990, complaints rose slightly (37 to 40) and investigations increased (2 to 3), while recalls dropped from 12 to 11 and TSBs climbed from 10 to 12. The following year, 1992 saw a sharp decline in complaints to 30, investigations dropped to 0, and recalls fell to 9, indicating the 1991 model represented a localized inflection point. The primary complaint areas—seat belts (15), hydraulic service brakes (6), and powertrain (4)—suggest potential safety concerns, though only 3 crash-related and 1 fire-related complaint were recorded. The trend shows complaints remained moderate through the mid-1990s before spiking in 1994 (82 complaints), then declining sharply in later years. Given that 1991 was the most investigated year of the generation and carries elevated seat belt and brake complaints relative to surrounding model years, buyers should exercise due diligence regarding these specific systems before purchase.
