2011 Acura RL

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2011 RL.

Body PASSENGER CARTransmission Automatic (S6)

The 2011 Acura RL is a passenger car fitted with an automatic (S6) transmission, rated by the EPA at 17/24/20 mpg, and specifies a 4.5-quart fill of 5W-20 API oil. Within the model’s 1996–2015 complaint history—a span that saw owner reports peak at 125 for the 2005 model year and bottom out at one for 2012—the 2011’s total of just three complaints places it among the least-troubled model years. Those three complaints, with the engine logged as the top concern, accompany six recalls and signal a comparatively uneventful year in the RL’s reliability history.

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 2011 Acura RL sits deep in the mature tail of the second-generation KB1/KB2 platform, recording just 3 complaints, 6 recalls, 0 investigations, and 91 TSBs, and it shows a clear generational arc in which the 2005 launch-year spike of 125 complaints, 11 recalls, and 3 investigations gave way to a steady decline through 2009 (8 complaints) and into the 2010–2012 window (9, 3, and 1 complaints respectively). The 6 recalls for 2011 are not anomalous—they match the 6–7 recall cadence seen every year from 2006 through 2012, suggesting a pattern of carryover campaign work rather than new, year-specific defects, and the 91 TSBs (up from 62 in 2010 and 63 in 2009) is the one figure that warrants attention as it indicates elevated service-bulletin activity even as hard complaints fell to a generation low. The three documented 2011 complaint areas—Engine, Vehicle Speed Control, and Air Bags—are each represented by a single report with no associated crash or fire incidents, which is a notably clean profile relative to the 2005 outlier year. The data does not specify root causes for the 2011 issues, but the volume is so low that statistical signal is weak. The takeaway: the 2011 model year is a defensible used buy on federal-record grounds—complaint volume is at its generation low, crash and fire counts are zero, and the recall count is simply the tail of a long-running campaign series—though a pre-purchase inspection should confirm that all six open recalls have been completed and that the high TSB count hasn't masked any intermittent drivability concerns specific to this car.
