1999 Acura RL

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1999 RL.

Body PASSENGER CAR

The 1999 Acura RL is a passenger car with a 4.9-quart oil capacity requiring 5W-30 viscosity, and it recorded 38 total owner complaints—placing it well below the model’s peak complaint year of 2005 (125 complaints) but above the lowest year of 2012 (1 complaint) across the 1996–2015 span. Its two recalls and top complaint area of air bags mark this model year as a relatively early point in the RL’s reliability history, where issues were still moderate compared to later peaks.

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 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.

In the context of this model generation, federal complaints trended downward to a low of 11 in 1998 before rising sharply to 38 in 1999 and nearly doubling again to 70 in 2000, while recalls held steady at 2 in 1999 versus 3 the prior year and 4 the following year. The 1999 model sits at the leading edge of this complaint escalation, recording 87 TSBs—up from 72 in 1998 and matching the 86 logged in 2000—while investigations remained at zero. For 1999 specifically, the top complaint areas were Air Bags (7), Power Train (5), Visibility (4), and Unknown or Other (4), accompanied by 2 crash-related and 2 fire-related complaints, though the data does not specify root causes. Compared with the 2005 peak of 125 complaints and 11 recalls, the 1999 model’s federal profile is moderate, but within its generation it marks a clear inflection point where complaints and service bulletins began a pronounced climb. Because 1999 initiates a distinct upward trend in complaints and technical service bulletins that continues into 2000, it is not the cleanest year of the generation; a well-documented maintenance history and thorough pre-purchase inspection are essential, making it a cautious buy rather than a standout choice.
