Lexus NX Reliability by Year

Every gasoline NX model year from 2015 to 2025, scored on reported failures weighted against how many were sold — and ranked against every other Mid-Size SUV of the same year.

Scored separately as its own vehicle: NX Hybrid (2015–2024).

The short answer

Best model year
2021
#3 of 53 that year
Year to avoid
2024
#30 of 72 that year
Latest scored
2025
#9 of 66

Across 11 scored model years the NX needs fixing less often than its class, and costs less to fix when it does. The spread between years is what matters: 2021 is its strongest, 2024 its weakest.

Every model year, scored

Longer bar is better. Rank is against every Mid-Size SUV sold that same model year.

Across all 11 model years on record, the line has held a strong position in its class.

What tends to break

All 12 systems, measured against the class average for each model year.

Every NX model year is scored across 12 separate systems — engine, transmission, brakes, electrical, steering and suspension, structure, interior, and five more. Each system is compared against how often that same system fails on the average Mid-Size SUV of the same year, so a common failure is judged against how common it is everywhere else.

Across the last three model years (2023–2025), the trouble concentrates in one place: tires & wheels. That system draws issue reports more often than the same system on the average Mid-Size SUV of its year — which changes what you should be inspecting before you buy.

Where does this data come from?

Failure reports filed with NHTSA — submitted by vehicle owners and repair shops alike — weighted against US sales volumes so a high-volume model is not penalised for selling well, then benchmarked within segment and model year.

How this was built. Scores derive from failure reports filed with NHTSA — submitted by vehicle owners and repair shops alike — weighted against US sales volumes and benchmarked within segment and model year. We measure two separate things: Fix Frequency — how often a vehicle needs fixing — and Fix Severity — how costly those fixes are. These figures describe a model line, not the specific vehicle in front of you; trim, mileage and service history still decide an individual car.
