Lexus NX 300h (2015-2021) Pros and Cons

Pros	Cons
Superb build quality	Not as fuel-efficient as the official figures suggest
Very unlikely to go wrong	Lots of road noise at speed
Comfortable and reasonably quiet if driven smoothly	Irritating infotainment system

Quick Summary

The Lexus NX 300h (2015-2021) is a premium SUV that stands as a compelling alternative to its German diesel rivals, offering superb build quality, stellar reliability, and a sophisticated self-charging hybrid powertrain. Combining a 2.5-litre petrol engine with an electric motor, it delivers a refined and quiet driving experience, especially in town where it can maximise electric propulsion. While the front seats can feel snug, the rear offers impressive space, and the boot is a practical size. The ride is generally comfortable, though road noise can be noticeable at speed.

Inside, the NX boasts a luxurious cabin with high-quality materials and a generous level of standard equipment across all trims. However, this is let down by a frustratingly unintuitive infotainment system controlled by a tricky touchpad. Running costs are reasonable for its class; while real-world fuel economy is closer to the mid-30s mpg than official figures suggest, the hybrid system's efficiency in urban driving and strong residual values make it an appealing long-term proposition. Lexus’s hybrid health check can also extend the battery warranty, adding to the peace of mind.

Best for: Buyers prioritising reliability, build quality, and refinement in a premium SUV. It's ideal for those who do a lot of town driving and want a well-equipped, comfortable alternative to a diesel.

Not ideal for: Drivers who need the most intuitive infotainment system, maximum fuel economy on long motorway journeys, or a particularly sporty driving feel.


Comparison vs Key Rivals



The Verdict

You should buy the NX if: You want a supremely reliable, well-built, and comfortable premium SUV with a refined hybrid powertrain and generous standard equipment.

Consider alternatives if: You prioritise an easy-to-use infotainment system, ultimate motorway fuel efficiency, or a sporty driving experience.

Competitive Position: The Lexus NX 300h (2015-2021) carves out a unique niche in the premium SUV market. It challenges the diesel-dominated German rivals like the BMW X3 and Audi Q5 by offering unparalleled reliability and a smooth hybrid powertrain. While it can't match them for driver engagement or infotainment technology, its high-quality interior, strong equipment levels, and excellent residual values make it a smart and dependable choice for buyers seeking long-term, trouble-free ownership.
