Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2015 TLX.
The 2015 Acura TLX enters the reference guide as a passenger car engineered around a 4.4-quart oil capacity with a 0W-20 viscosity requirement, a detail that underscores its precise maintenance needs. This model year stands out in the vehicle’s history for all the wrong reasons, however, as it accumulated 340 owner complaints—the highest of any year from 2012 to 2025—with the power train emerging as the primary trouble spot alongside six recalls, marking it as a notably problematic vintage that demands careful scrutiny from researchers.
Fluid capacities, tune-up values and fuel economy at a glance.
Replacement part sizes and factory part numbers — battery, bulbs, filters and belts.
From the factory this vehicle uses a BCI 35 · 440 CCA battery. Each part links to every other vehicle that shares it, so a part you already stock may fit more of your fleet than you'd expect.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The 2015 Acura TLX presents the worst complaint record of its generation, with 340 complaints, 6 recalls, 2 investigations, and 427 TSBs—numbers that dwarf every subsequent model year in the dataset. Comparing this peak to the preceding 2012 model (1 complaint, 0 recalls) and the following 2016 model (109 complaints, 3 recalls, 248 TSBs) reveals a dramatic spike at launch that steadily improves across the generation. The primary complaint driver is Power Train at 100 instances, followed by Engine (25), Unknown or Other (20), and Electrical System (13), with 12 crash-related complaints and zero fire complaints. The recall count of 6 is tied for the highest in the dataset with 2019, but the 2 investigations remain consistent across 2015 through at least 2016, indicating ongoing federal scrutiny at launch. This arc suggests the 2015 model suffered significant early-life problems that were largely addressed through subsequent model years. A buyer should avoid the 2015 model year in favor of a 2016 or later example, where complaint rates dropped by roughly two-thirds and TSBs halved, indicating substantially improved reliability and resolved manufacturing issues.
