Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2016 RLX.
The 2016 Acura RLX is a passenger car equipped with an automatic (S6) transmission and EPA ratings of 20/30/23 mpg, with routine service requiring 4.5 quarts of 0W-20 engine oil. Across the 2014–2020 complaint history, the 2016 model year generated only four owner complaints—far below the 83 recorded for 2014—with steering flagged as the top complaint area and zero recalls issued. That low-complaint profile places the 2016 model among the most reliable years in the RLX’s production span, part of a broader pattern that saw complaints drop to a low of two by 2020.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The 2016 Acura RLX sits in a notably stable middle of its generation's federal record, well past the volatile 2014 launch year that generated 83 complaints and 5 recalls, and showing continued improvement over the already-cleaner 2015 model (11 complaints, 3 recalls). Complaints had collapsed to just 4, no recalls were issued for the target year, and the 2 open investigations had been carried over unchanged from prior model years rather than being newly opened against 2016 — a sign the platform's known issues were already on regulators' radar. Technical Service Bulletins were still flowing at 97 for 2016, but the downward trajectory across the generation (188 → 157 → 97 → 50 → 21 → 15 → 10) suggests Acura was systematically addressing the early-build gremlins rather than letting them persist. The four complaint areas tied at a single report each (Steering, Electrical System/Structure, Suspension/Wheels, Air Bags) point to no concentrated failure mode, and the lone crash complaint with zero fire reports is reassuring. The data doesn't specify root causes for these isolated filings, but the pattern indicates the 2016 is a meaningfully better bet than the 2014 launch-year cars and essentially on par with the 2017. As a used buy, the 2016 model year represents a strong value position in the RLX generation — most of the early teething problems are behind it, recall exposure is zero, and the single-digit complaint count compares favorably with most luxury sedans of the era.
