After accumulating over 10,000 miles, the 2025 Acura ADX has been thoroughly evaluated as a long-term review vehicle, revealing both commendable features and significant drawbacks. Overall, the compact luxury SUV continues to satisfy as a comfortable and uncomplicated daily driver, yet specific aspects of its performance have emerged as points of contention or praise.

One of the most notable annoyances stems from the vehicle's driver-assist systems, particularly its adaptive cruise control. This system has been observed to be concerningly slow in reacting to changes in the leading vehicle's speed, often taking nearly four seconds to initiate braking after a preceding car decelerates. This delayed reaction frequently necessitates hard braking, which can be jarring for occupants and inconvenient for following drivers. Furthermore, the system tends to brake unnecessarily for small decelerations rather than coasting, leading to a ripple effect of braking for vehicles behind. Another significant flaw is its tendency to misinterpret vehicles turning in parallel lanes as the leading car, causing abrupt and uncalled-for braking even when there is ample clear space ahead, despite the lane keep assist functioning accurately.

In contrast to the driver-assist frustrations, the 2025 Acura ADX shines in its audio performance, especially for models equipped with the high-end A-Spec with Advance trim. This particular trim level features an exclusive 15-speaker Bang & Olufsen audio system, which is a substantial upgrade over the standard eight-speaker setup. The Bang & Olufsen system delivers a rich, clear, and exceptionally immersive sound experience, living up to the expectations of a vehicle positioned within the luxury category.

However, the cabin's acoustics present another area of complaint: persistent road noise. After spending time in other vehicles, the ADX's noisy interior often becomes apparent upon reentry. While some wind noise is present, the more prominent issue is tire noise, which is noticeably amplified at freeway speeds and becomes particularly intrusive on pavement with even a slightly gritty texture. While this level of noise is generally tolerable, it is a point worth considering when evaluating the ADX's qualifications as an upscale vehicle.

In summary, while the 2025 Acura ADX largely fulfills its role as a comfortable luxury SUV, the experience is marked by a clear dichotomy between its impressive premium audio system and the less refined aspects of its driver-assist technology and cabin quietness. These detailed observations from over 10,000 miles provide a comprehensive look at the vehicle's strengths and weaknesses in daily use.
