The 2015 Acura TLX offers two distinct engine options: a powerful 3.5-liter V6 and a fuel-efficient 2.4-liter inline-4. Choosing the right engine depends on individual needs and priorities. This article examines the potential benefits and drawbacks of each powertrain, focusing on common issues and long-term reliability.
The 2.4-liter inline-4 (i4) engine, known as the K24W7, is generally considered highly reliable, especially in later models. However, the 8-speed dual-clutch transmission (DCT) paired with the i4 in the 2015 TLX might exhibit some quirks that were addressed in subsequent model years. These potential issues primarily involve transmission behavior rather than engine problems.
The 3.5-liter V6 engine delivers significantly more power and often comes with all-wheel drive (AWD). However, it’s important to acknowledge potential issues associated with the ZF 9-speed automatic transmission. While numerous fixes and adjustments have improved its performance and reliability, some quirks may persist. These issues primarily relate to transmission behavior and are not typically indicative of widespread engine problems.
A less common but more severe issue reported with the V6 engine involves potential rod bearing failures, leading to catastrophic engine damage. While this problem seems more prevalent in later model years (2018-2020), it’s worth considering when evaluating a 2015 TLX with the V6. Acura offered warranty coverage for this issue in later models.
Ultimately, the best way to decide between the 2015 Acura TLX’s two engines is through a test drive. Experience firsthand the driving characteristics of each powertrain and consider individual needs and priorities. If power and AWD are essential, the V6, despite potential transmission quirks, offers compelling performance. If reliability and fuel efficiency are paramount, the i4, coupled with its potentially finicky 8-speed DCT, presents a more economical and potentially less problematic ownership experience. Remember to research and factor in potential maintenance and repair costs associated with each engine option.
