Mazda MX-5 IV (ND) (2015 – 2025)

Reliability score : 8.8/10

The Mazda MX-5 ND (4th generation) represents a triumphant return to the model's original 'Jinba Ittai' (horse and rider as one) philosophy. Significantly lighter and more compact than its NC predecessor, the ND focuses on pure driving dynamics, naturally aspirated engines, and rear-wheel drive. The production run is generally divided into three main phases: * ND1 (2015-2018): Introduction of the 1.5L (131 hp) and 2.0L (160 hp) Skyactiv-G engines. * ND2 (2019-2023): Major engine update for the 2.0L, raising the redline to 7,500 rpm and power to 184 hp (181 hp in North America). The 1.5L received a minor bump to 132 hp. Addition of a telescopic steering wheel. * ND3 (2024+): Minor facelift, updated infotainment system (8.8-inch screen), new asymmetric limited-slip differential (LSD), and re

✅ Strengths

Exceptional driving dynamics and chassis balance (50:50 weight distribution).
Bulletproof reliability of the Skyactiv-G engine blocks (both 1.5L and 2.0L).
Very low running costs (excellent fuel economy, affordable consumables).
ND2 2.0L engine is a masterpiece of naturally aspirated engineering.
One of the best manual gearboxes on the market (when not affected by early ND1 flaws).

⚠️ Weaknesses

Early ND1 2.0L manual transmissions are prone to failure (2nd/3rd gear).
Paint quality is notoriously thin, especially 'Soul Red Crystal' (code 46V), which chips very easily.
Infotainment screen 'ghost touch' and delamination issues on pre-2024 models.
Cabin noise is high at highway speeds (even on the RF model).
Very limited interior storage and small trunk space.

🎯 Verdict

The Mazda MX-5 ND is an outstanding sports car and one of the most reliable performance vehicles on the market today. The Skyactiv-G engines are incredibly robust, and the car's simplicity keeps maintenance costs low. Buying Advice: If budget allows, the ND2 (2019+) 2.0L is the absolute sweet spot, offering a thrilling 7,500 rpm redline and a reinforced gearbox. If you are looking at an early ND1 2.0L (2016-2017), you must verify the gearbox history; if it hasn't been replaced with a later revision, budget for a potential failure if you drive aggressively or track the car. The 1.5L model is a hidden gem—immune to the gearbox issues due to lower torque, and arguably offers the purest, most rev-happy 'classic roadster' experience for street driving.
