The best Acura NSX years are 1997 through 2005 for the first generation, and 2019 through 2022 for the second generation. Avoid early 1990s manuals and 2017 models due to transmission and hybrid system concerns.
Rankings are comparative, and no vintage supercar is flawless. Maintenance history, timing belt service, and overall condition matter far more than the odometer reading when evaluating these high-performance vehicles.
Meaningful differences exist between the naturally aspirated first generation and the twin-turbo hybrid second generation. Transmission types and specific facelift years also heavily influence reliability and long-term ownership costs.

How We Evaluated the Acura NSX Model Years
Our analysis considers official recalls, manufacturer service campaigns, and verified owner complaints. We evaluate powertrain differences, generation changes, and repair complexity to determine long-term reliability.
Consumer complaints are not confirmed defects, and a recall does not automatically make a vehicle unreliable. Recent models have less ownership history, making long-term predictions difficult.
Best Acura NSX Years
1997–2005 (First Generation)
These years represent the pinnacle of the original NSX design. The 1997 model year introduced a larger 3.2-liter V6 and a six-speed manual transmission for improved performance.
Later models received a comprehensive facelift with fixed HID headlights and revised suspension. The platform was thoroughly sorted, making these the most dependable options for collectors.
2019–2022 (Second Generation)
Following its 2017 debut, the second-generation NSX received crucial software and mechanical updates. The 2019 refresh improved suspension tuning and standard features, resolving many early-production quirks.
The 2022 Type S serves as the ultimate farewell edition. While maintenance costs are high, these late-model years offer the most refined hybrid supercar experience available.
Best Year by Buyer Type
- Best Overall: 2002–2005. These facelifted first-generation models combine modern styling with bulletproof naturally aspirated reliability.
- Best Enthusiast Choice: 1997–2001. The introduction of the 3.2-liter engine and six-speed manual transmission makes these highly desirable for driving purists.
- Best Modern Alternative: 2020–2022. Later second-generation models offer cutting-edge hybrid performance without the teething issues of the 2017 launch year.
Years to Approach Carefully
1991–1996 (First Generation)
Early first-generation models are legendary, but 1991 and 1992 manual transmissions suffered from a notorious snap-ring flaw. This issue could cause catastrophic transmission failure if left unaddressed.
Additionally, aging electronics and pop-up headlight motors frequently require attention. Buyers must verify that the transmission was rebuilt or updated and that the timing belt was serviced.
2018 (Second Generation)
The 2018 model year carried over the initial launch hardware before the 2019 refresh. While improved via software updates, it still shares some early hybrid system vulnerabilities.
Buyers must ensure all technical service bulletins were applied. A comprehensive dealership diagnostic scan is mandatory to verify the high-voltage system and dual-clutch transmission health.
Worst Acura NSX Years
2017 (Second Generation)
The 2017 model year is the most problematic of the modern era. As a first-year redesign featuring an incredibly complex twin-turbo hybrid powertrain, it suffered from numerous software and transmission issues.
Owners reported DCT hesitation, 12-volt battery drains, and hybrid system warnings. While later updates resolved some concerns, the 2017 model remains the riskiest modern NSX to purchase.
Acura NSX Reliability by Generation
First Generation (1991–2005)
Sold as the Acura NSX in the United States, this generation is famous for its Honda engineering. The naturally aspirated V6 engines are incredibly durable when properly maintained.
The primary concern is the timing belt and water pump service, which requires dropping the engine or extensive labor. Rust and aging rubber components also demand careful inspection.
Second Generation (2017–2022)
The NC1 generation introduced a twin-turbo V6 paired with a three-motor Sport Hybrid system. While technologically advanced, the complexity makes out-of-warranty repairs exceptionally expensive.
Reliability heavily depends on software updates and hybrid battery health. Unlike the first generation, these cars are not suited for DIY maintenance and require specialized Acura dealerships.
Common Acura NSX Problems
Transmission Snap-Ring Failure (1991–1992)
Early manual transmissions featured a faulty snap-ring that could break and destroy the gearbox. Acura issued a recall, but buyers must verify the repair was completed decades ago.
Timing Belt and Water Pump Service (All First-Gen)
While not a defect, the timing belt must be replaced every six years or 90,000 miles. The mid-engine layout makes this a labor-intensive and expensive maintenance requirement.
Hybrid System and DCT Issues (2017–2018)
Early second-generation models experienced dual-clutch transmission shudder and hybrid system software faults. Ensuring all technical service bulletins and recall updates are applied is critical for these years.
What to Check Before Buying a Used Acura NSX
- Verify the VIN for open recalls, especially regarding the second-generation fuel tank and hybrid system.
- Inspect documentation for timing belt and water pump replacements on all first-generation models.
- Test the dual-clutch transmission for shudder or hesitation during low-speed maneuvers on second-generation cars.
- Check the operation of pop-up headlight motors and aging interior electronics on pre-2002 models.
- Arrange an independent pre-purchase inspection with a specialist familiar with mid-engine Honda vehicles.
