The 2015 Acura TLX presents a compelling package of comfort and value, but its reliability is a tale of two transmissions.

Best Model Years
For the TLX generally, 2018+ saw transmission improvements. For the 2015 specifically, the 2.4L I4 model is the best choice.
Years to Avoid
V6 models from 2015-2017 are the riskiest due to the unrefined and problematic ZF 9-speed automatic transmission.

Top Risk Areas
The systems that tend to fail first on the 2015 Acura TLX, with the typical mileage window when each becomes a concern. Detailed repair-cost ranges and exact what-to-check inspection notes are in the full report.
The ZF 9-speed automatic transmission (found in V6 models) is prone to harsh shifts, shuddering, delayed engagement, and outright failure due to software and hardware issues. This is a critical and expensive problem.
The dual-screen infotainment system can freeze, become unresponsive, or experience Bluetooth connectivity issues. While often fixable with software updates or resets, it's a persistent annoyance.
Reports of A/C compressors failing prematurely, leading to a loss of cooling. This often requires replacement of the compressor and sometimes the entire system.
2015 Acura TLX Mileage Danger Zones
The mileage windows when the 2015 Acura TLX most commonly needs attention. Plan ahead, budget accordingly, and inspect before you cross each threshold.
Early Annoyance Zone
At this mileage, expect early signs of infotainment glitches, potential brake pulsation, or minor rattles to emerge. These are typically software-related or minor wear items.
Transmission Watch Zone
This is a critical mileage for V6 models; the ZF 9-speed transmission frequently begins to exhibit harsh shifts or shuddering here. Regular maintenance items like spark plugs and fluid changes are also due.

Beyond this point, suspension components will likely require attention, and the A/C compressor is a common failure point. The ZF 9-speed transmission in V6 models becomes a significant financial liability.
High Risk Zone
At this mileage, virtually all V6 TLXs will have either had transmission work done or be facing imminent major transmission failure. Expect significant investment in wear items and potential for larger electrical issues.

How Long Does the 2015 Acura TLX Last?
For a 2.4L model, under 80,000 miles is ideal, allowing for many years of reliable service. For a V6 model, I would strongly advise against anything over 50,000 miles unless documented transmission replacement or extensive repair has been performed.
