Split by first-registration year. Cars registered in a changeover year can belong to either generation.
Computed from DVSA MOT results, all of Great Britain, 2025. Nothing here is opinion.
Share of tests where each item was recorded. The dark tick is the class average across all tracked models; bars are scaled within each group.
The rows that judge the model rather than its keeper. 15,092 tests in this band.
Tyres, pads and stone chips say more about how the car was driven and maintained than about how it was built.
Owner folklore from forums and the motoring press. Most of it never shows up in an MOT, which is why this section exists at all.
On 2019 petrol NX cars a faulty low-pressure fuel pump can starve the engine of fuel and make it stall or fail to restart, sometimes with no warning at all. Toyota and Lexus recalled the affected cars to replace the pump assembly free of charge. If you're looking at a 2019 petrol NX, check the recall has actually been carried out before you rely on the car.
A fault traced to noise-filter resistors in the brake ECU can make the electronic parking brake refuse to engage or release on NX250 and NX350 cars built between April 2021 and August 2022, throwing up a 'Parking Brake Malfunction, visit your dealer' message. Lexus recalled the affected cars for a free software update. Check the service history for the recall on any car from that build window.
Owners regularly report creaks, knocks and rattles from the front end, most often traced to strut top mounts, bushes or a loose brace or side-step fitting rather than anything structural, usually from around 60k miles. Fixing it can take more than one visit since it's often a degrease-and-retorque job rather than new parts. Suspension is the measured MOT signature fault for large SUVs as a class, and on the NX the owner complaints line up with that, though what forums describe is closer to an annoying rattle-hunt than a safety-critical wear item.
Pre-2022 NX cars control the infotainment with a touchpad or joystick instead of a touchscreen, and it's a near-universal gripe: the cursor overshoots, the steering-wheel-mounted pad on some trims shifts as you steer, and simple jobs like changing radio station take longer than they should. It's not a fault that breaks, more a design flaw that grates daily, and Lexus replaced it with a touchscreen from the second-generation NX in 2022. Worth trying it for a few minutes on a test drive, since some buyers genuinely can't live with it.
The 2.0-litre turbo petrol engines (NX200t, NX300, NX250, NX350) use direct injection, which can leave carbon deposits on the backs of the intake valves over time, showing up as a rough idle, hesitation or a misfire warning light from around 60k miles. The NX's dual-injection set-up, direct plus port injectors, is meant to reduce this compared with pure direct-injection rivals, but owners still report needing a walnut-blast clean at higher mileage. It's a maintenance job rather than a warranty claim, typically a few hundred pounds.
On 2022 NX450h+ plug-in hybrids, a component inside the DC-DC converter could have been damaged during manufacture, risking a short circuit, overheating and in the worst case a fire. Lexus recalled affected cars to replace the converter free of charge. Check the recall has been completed on any 450h+ before you buy it; there are no equivalent reports on the regular NX300h or NX350 hybrid, which don't use this part.
