Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2003 CL.

Body PASSENGER CAR

The 2003 Acura CL is a passenger‑car built on Acura’s mid‑size platform and equipped with a powertrain that requires 4.6 qt of 5W‑20 API oil. Across its 1997‑2004 production run, the model accumulated 79 owner complaints overall, with the power‑train identified as the most frequent issue area and five recalls issued for the generation. Compared with the peak of 274 complaints recorded in 2001, the 2003 CL sits toward the lower end of the series’ trouble‑report curve, approaching the 2004 low of just one complaint, indicating a comparatively steadier reliability record for researchers to note.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 15,000 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.

The 2003 Acura CL sits at the end of a generation that saw a dramatic complaint spike in 2001 (274 complaints) before settling to 61 in 2002, then rising again to 79 in the target year. More critically, the 2003 model year carries the highest number of recalls (5) and investigations (4) in the entire dataset, alongside a peak in technical service bulletins (177), signaling that serious, widespread issues were being addressed by the manufacturer. The top complaint area is the power train with 33 reports, and there were 7 crash-related complaints, though no fire complaints. Compared to earlier years, the 2003 CL shows a troubling concentration of federal oversight and corrective actions, even as raw complaint volume is not the highest. This pattern suggests that while the vehicle may have fewer overall owner gripes than the troubled 2001 launch, the problems it does have are significant enough to trigger multiple investigations and recalls. A buyer should be cautious: the 2003 Acura CL’s federal record points to a higher risk of unresolved serious defects, particularly in the power train, making it a less reliable choice than the 2002 model year.
