The 2021 Mazda MX-5 Miata is a lightweight, two-seat convertible sports car designed for drivers who prioritize feel, handling, and top-down fun over outright power or cargo space. It’s part of the ND-generation Miata (introduced for 2016 and updated for 2019 with more power), and it remains one of the most engaging affordable roadsters on the market. The 2021 model is ideal for weekend drives, commuting with a smile, and anyone who wants a simple, rear-wheel-drive sports car without supercar running costs. In its segment, the Miata stands out for reliability, low curb weight, and crisp manual-transmission character.

- 2.0L SKYACTIV-G 4-cylinder engine (ND2), 181 hp and 151 lb-ft of torque, paired with a 6-speed manual or 6-speed automatic depending on trim. - Rear-wheel drive with a near-50/50 balance feel, quick steering, and a low curb weight (around 2,300–2,400 lbs depending on trim and top). - Choice of soft top (classic MX-5) or RF (Retractable Fastback) with a power-folding targa-style roof for added security and a quieter cabin. - Available performance hardware on Club trims, including a limited-slip differential (manual transmission models), Bilstein dampers, and front shock tower brace for sharper handling. - Modern driver and tech essentials for 2021, including available i-ACTIVSENSE safety features (such as Blind Spot Monitoring and Rear Cross Traffic Alert) and Mazda Connect infotainment with smartphone integration depending on configuration.

Shoppers researching 2021 Mazda MX-5 Miata reliability and 2021 Mazda MX-5 Miata common issues generally find the Miata to be above-average for dependability, but no car is perfect. Here are problems reported by some 2021 Mazda MX-5 Miata owners, along with what to watch for: 1) Soft top wear, wind noise, and weather sealing concerns: On soft-top models, the fabric and seals can develop increased wind noise, small leaks, or accelerated wear if the top is frequently folded while dirty or if seals aren’t kept clean. This can show up within the first 10,000–30,000 miles depending on use and storage. 2) Infotainment glitches and Bluetooth connectivity dropouts: Some owners report Mazda Connect freezes, rebooting, or intermittent Bluetooth/USB connection problems. These issues are often software-related and may be improved with updates, but can be annoying in daily use. 3) Brake noise and uneven wear: The Miata’s brakes can squeal or make scraping noises, especially in cold weather or after sitting, and spirited driving can accelerate pad and rotor wear. Depending on driving style, pads may need attention anywhere from 15,000–35,000 miles. 4) Manual transmission feel concerns (not universal): While the ND Miata is generally solid, a subset of drivers note notchiness, occasional gear grind, or clutch feel changes, sometimes after aggressive shifting or track use. Not every 2021 car is affected, but it’s worth paying attention during a test drive.
