Top Risk Areas
The systems that tend to fail first on the 2018 Acura NSX, 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.
While generally durable, the high-voltage battery and associated power control units are complex. Failures are rare but extremely costly due to specialized parts and labor, typically manifesting as warning lights or reduced power.
The sophisticated DCT can occasionally exhibit rough shifts, software glitches, or, in rare cases, require expensive mechatronic unit replacements. Fluid changes are critical, and neglected maintenance can lead to premature wear.
The active suspension system components, including the adaptive dampers, can eventually develop leaks or electronic sensor faults. Replacement parts are proprietary and labor-intensive, leading to significant repair bills.
