What Problems Does the 1991 Acura NSX Have?
The 1991 Acura NSX is renowned for its robust build quality, a testament to Honda's engineering prowess. However, like any aging performance car, it has developed some known issues over time. One of the most commonly reported concerns revolves around the clutch, particularly on higher-mileage vehicles. While generally durable, the original clutch had a finite lifespan and replacements can be costly. Another critical maintenance item is the timing belt and water pump, which require periodic replacement (typically every 60,000 miles or 5-7 years). Neglecting this can lead to catastrophic engine damage. Fuel injectors can also become clogged over time, affecting performance and fuel economy, though this is often addressable with cleaning or replacement. Early models, including the 1991, could sometimes experience electrical gremlins, such as faulty window regulators or dashboard illumination issues. The ABS system, while effective, can also develop faults with age, requiring attention. For the 1991 model year specifically, there haven't been widespread, significant recalls that impacted the entire production run in the way some other vehicles have experienced. However, it's crucial for any prospective buyer to have a thorough pre-purchase inspection by a mechanic experienced with the NSX. Long-term reliability is generally excellent, provided diligent maintenance. The aluminum chassis, while preventing rust, can be susceptible to damage from impacts, so checking for accident history is paramount. Despite these potential issues, the NSX is considered one of the most reliable exotic cars ever produced, with many owners reporting trouble-free ownership when proper care is given.
How long will the 1991 Acura NSX last?
Based on owner data and maintenance habits, the 1991 Acura NSX can realistically achieve well over 200,000 miles, with many examples far exceeding this mark. The long-term durability is exceptional, largely due to the high-quality engineering and robust V6 engine. However, this longevity is contingent on meticulous and consistent maintenance. Weaknesses that emerge over time are primarily related to wear and tear on components like the clutch, suspension bushings, and aging electrical systems. The aluminum construction is remarkably resistant to corrosion, a significant advantage over steel-bodied contemporaries. With regular fluid changes, timely belt replacements, and addressing minor issues promptly, the NSX demonstrates remarkable resilience and can remain a reliable and enjoyable driver for decades.
What Technology & Safety Features are Included?
The 1991 Acura NSX, while a performance-focused machine, offered a respectable suite of technology and safety features for its era, though it eschewed the flashy electronics of some competitors. Standard tech included power windows, power door locks, cruise control, and a premium audio system. The climate control system was also power-assisted. Entertainment was primarily delivered through the factory stereo, which often featured an AM/FM radio and cassette player. While Bluetooth or modern infotainment systems were non-existent, the focus was on the driving experience. Driver-assistance features were limited, with the primary inclusion being a four-wheel anti-lock braking system (ABS), which was quite advanced for its time. Power steering was standard, aiding maneuverability. Safety features included driver and passenger front airbags, along with a very rigid all-aluminum unibody structure designed to absorb impact energy. Optional features were less about technology and more about driver preference, such as the removable targa top on the NSX-T variant (though the 1991 was primarily a coupe). Crash-test ratings for vehicles of this vintage are not directly comparable to today's stringent standards. However, the NSX was engineered with a strong emphasis on occupant protection through its sophisticated chassis design and airbag systems, reflecting Acura's commitment to safety even in a performance car. The overall tech package was functional and driver-centric, prioritizing the sensory experience of driving over digital distractions.

How Does the 1991 Acura NSX Compare to Other Sedan?
The 1991 Acura NSX carved a unique niche, often stacked against icons like the Ferrari 348, Porsche 911 (964 generation), and Chevrolet Corvette ZR-1. In terms of performance, the NSX offered razor-sharp handling and impressive VTEC power, though its outright top speed might have lagged slightly behind some rivals. Its mid-engine layout provided superior weight distribution for agility. Feature-wise, the NSX was well-equipped with creature comforts, but lacked the flamboyant luxury of some European counterparts, prioritizing driver focus. The NSX's trump card, however, was its legendary Honda reliability. While the Ferrari 348 and Porsche 911 of the era were known for their more demanding maintenance schedules and potential for costly repairs, the NSX offered a level of dependability unheard of in exotic cars. This reliability came at a price point that was competitive, often slightly more affordable than a comparable Ferrari, but more expensive than a Corvette ZR-1.
Similar Alternatives:
For those prioritizing reliability and a fantastic driving experience without the constant worry of expensive repairs, the 1991 NSX is arguably the superior choice. If raw V8 power and Italian pedigree are paramount, a Ferrari might appeal, but at a much greater cost and commitment to upkeep.
Similar Alternatives:
