Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2014 RLX.
The 2014 Acura RLX is a passenger car powered by a 0W-20 API engine requiring 4.5 quarts of oil, paired with an automatic 6-speed transmission and EPA-rated at 20/30/23 mpg. Within the 2014–2020 RLX complaint record, the 2014 model stands out as the most reported year, logging 83 owner complaints against the generation-low of 2 for 2020, with steering cited as the top complaint area and 5 recalls on file. That concentration of early-run feedback makes the 2014 RLX the most scrutinized year of the lineup, so researchers should treat steering-related reports and recall history as the primary due-diligence focus.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The 2014 Acura RLX recorded 83 complaints, five recalls, two investigations and 188 technical service bulletins, the highest complaint count in the 2014‑2020 span. By contrast, complaints fell to 11 in 2015, remained low at four in 2016 and three in 2017 before a modest rise to six in 2018 and near‑zero levels in 2019‑2020. Recalls followed a similar pattern, dropping from five in 2014 to three in 2015, none in 2016‑2017, then fluctuating between one and three in later years. Investigations were steady at two per year from 2014 through 2017, then decreased to one in 2018‑2019 and none in 2020, while TSBs declined steadily over the period. Given the markedly higher complaint and recall burden in 2014 relative to subsequent model years, this year represents a less favorable choice for a used purchase.
