Lexus NX II (AZ20) (2021 – 2025)

Reliability score : 9.2/10

The second-generation Lexus NX (AZ20) marks a major turning point for the Japanese brand's premium compact SUV. Based on the TNGA-K modular platform (shared with the Toyota RAV4), it corrects its predecessor's main flaw: its obsolete touchpad infotainment system, replaced by the highly modern Lexus Interface (touchscreen up to 14 inches). It is also the first Lexus model to introduce a plug-in hybrid powertrain (PHEV) with the NX 450h+, alongside the traditional self-charging hybrid (NX 350h). True to the brand's reputation, build quality, soundproofing, and overall reliability are at the top of the category. It stands out as one of the most rational and durable choices against the German trio (Audi Q5, BMW X3, Mercedes GLC).

✅ Strengths

Exceptional mechanical reliability (4th generation Toyota/Lexus hybrid system)
Impressive real-world fuel consumption on the NX 350h (often under 6.0 L/100 km)
New multimedia system finally on par with the competition (fast and intuitive)
Finish quality, material assembly, and cabin soundproofing
Very high resale value on the used market

⚠️ Weaknesses

Average trunk volume for the category, especially on the PHEV (cables under the floor)
Combustion engine (e-CVT) can still be heard during hard acceleration
Driving aids (ADAS) sometimes too intrusive (frequent audible alerts)
12V battery sensitive to long periods of inactivity on hybrid versions

🎯 Verdict

The second-generation Lexus NX is a true best buy in the premium compact SUV category. It erases the ergonomic flaws of its predecessor while maintaining almost unmatched mechanical reliability on the market. The NX 350h version is the most well-rounded choice, offering negligible fuel consumption for a vehicle of this size. The NX 450h+ is excellent for businesses or those who can charge daily, although it is heavy. The recorded recalls are numerous but mostly concern software updates (cameras, parking aids) or minor adjustments covered by the manufacturer, without tarnishing the robustness of the powertrains.
