Overview

The 2021 Acura NSX is a mid-engine, all-wheel-drive hybrid supercar designed for drivers who want exotic performance with everyday usability. Positioned against rivals like the Audi R8 and McLaren Sports Series, it blends twin-turbo V6 power with three electric motors for instant torque and strong all-weather traction. This model remains part of the second-generation NSX introduced for 2017, with refinements carried forward rather than a full redesign. It’s ideal for enthusiasts who value technology, sharp handling, and a performance car that can still be driven regularly.

Key Features

- Hybrid powertrain with Super Handling All-Wheel Drive (Sport Hybrid SH-AWD): a 3.5L twin-turbocharged V6 paired with three electric motors for quick response and corner-exit traction. - Strong performance numbers: 573 horsepower (combined system output) and rapid dual-clutch shifting via a 9-speed automatic transmission with paddle shifters. - Multiple drive modes: Quiet, Sport, Sport+, and Track tailor throttle, steering, suspension damping, and hybrid response for street or circuit use. - Braking and chassis tech: large performance brakes and a rigid, lightweight structure help deliver consistent stopping power and precise turn-in. - Modern cockpit and daily-drive features: supportive sport seats, a low-slung supercar seating position, and available driver-assist features depending on configuration, plus usable storage for weekend trips.

Common Issues & Reliability

Searching “2021 Acura NSX problems” or “2021 Acura NSX common issues” often brings up a few themes. Overall, the NSX benefits from Acura engineering, but it’s a complex hybrid supercar, so small issues can be expensive to diagnose and repair. 1) Infotainment and connectivity glitches: Some owners report intermittent screen freezing, Bluetooth pairing drops, or navigation/backup camera lag. These complaints can show up early in ownership (often within the first 5,000–20,000 miles) and may be improved with software updates, module resets, or component replacement if a unit fails. 2) Battery and charging-system concerns: The 12-volt battery can be sensitive to short-trip driving or extended storage, leading to low-voltage warnings, no-start conditions, or strange electronic behavior. Owners who don’t drive regularly may see this within a couple of years, especially if the car sits without a tender. 3) Brake noise and accelerated wear in certain use cases: Squeal, vibration, or faster-than-expected pad/rotor wear can occur, particularly with frequent spirited driving or track days. Some owners notice noise at low speeds even with plenty of pad life remaining; bedding procedures, pad choice, and proper brake service help. 4) Minor fit-and-finish and rattle complaints: A few owners mention interior squeaks/rattles, window seal noise, or trim buzzes that can be more noticeable in a stiff, performance-focused chassis. These tend to appear as mileage accumulates (often 10,000–30,000 miles) and are usually addressed with adjustments rather than major repairs.
