7.4/10
1 walk-away risk, 1 serious fault, 6 minor faults documented for this generation, weighted by severity and repair cost. Biggest factor: brake booster no-code system malfunction. Score methodology.
The 2022-2025 NX is a much more modern Lexus than the first generation, but it also brings more software, camera, brake and hybrid/PHEV dependencies. The expensive traps are current non-hybrid fuel-hose/fuel-pump recall exposure, brake-booster "system malfunction" bulletins, panoramic-view camera software recalls, NX450h+ charging or fuel-tank complaints, infotainment/amplifier issues, and run-flat tyre cost. The safest buy is a 2024-2025 NX350h with closed recalls, clean hybrid scan, updated multimedia software and no brake warnings. Owners should use warranty aggressively for intermittent warnings because second-gen NX faults are often bulletin-driven rather than obvious mechanical failures.

Best years
2024-2025
Best buys

- NX450h+ only with home charging, EV range proof and no charging/fuel-tank complaints.
Inspect hard
- 2022 launch cars for multimedia, camera, brake warning and early software history.
- 2022-2025 NX250/NX350 for 2025 fuel-pump/fuel-hose recall eligibility.
- Any PVM-equipped car for backup-camera freeze or blank-screen recall updates.
Avoid
- Any NX with active brake warning, red system malfunction or no-code brake complaint.
- NX450h+ with charging faults and no dealer printout.
- Cars on mismatched run-flats or damaged wheels.
Next checks
Before you contact the seller
Check the car's history first. Then bring the right tools if it still looks worth viewing.
Primary next step
Check history, title, and recall status
The faults above matter more if the car also has accident history, finance flags, missing service records, or open safety recalls.

Engines and trims
Which Lexus NX should you buy?
On most used cars, the engine and trim choice changes the risk more than the mileage does. Narrow this down before you start viewing cars.
NX250 A25A-FKS 2.5 petrol
2022-2025
LOW-STRESS BUT SLOW
The base engine is simple for this generation, but it is not quick and sits inside the same recall/software ecosystem as pricier NX trims. Buy it only after fuel-system and camera recalls are checked.
NX350 T24A-FTS 2.4 turbo
2022-2025
FASTEST NORMAL NX, INSPECT COOLING AND FUEL SYSTEM
The turbo makes the NX feel properly premium but adds heat, hoses and boost hardware. Current fuel-hose/fuel-pump safety actions make VIN status essential.
NX350h A25A-FXS hybrid
2022-2025
BEST ALL-ROUND BUY
The hybrid fits the NX best: strong economy, smooth urban use and less turbo complexity. It still needs 12V, brake and hybrid-system scanning because warning cascades are common on modern Toyota/Lexus hybrids.
NX450h+ plug-in hybrid
2022-2025
EXCELLENT ONLY WITH CHARGING PROOF
The PHEV is the premium pick if charged at home. It is the wrong blind buy because EV range, charge-port operation, fuel-tank behavior and high-voltage warranty status must be verified.
Year notes
Year-by-year buyer advice
Use this to narrow the search before you spend time travelling to view a car.
2022
Second-generation NX launches with new hybrid, turbo, PHEV, multimedia and driver-assist architecture.
Buyer: Inspect launch cars hard for software, brake warnings, camera updates and charging behavior.
Owner: Use warranty for every repeat warning; early software history matters.
2023
Production settles but multimedia and amplifier/phone TSBs remain relevant.
Buyer: Good buy if dealer updates are complete and no brake/camera faults appear.
Owner: Keep update receipts because intermittent tech complaints hurt resale.
2024
More mature year; brake-booster and parking-brake/noise bulletins still need checking by symptom.
Buyer: NX350h is the target if the scan is clean.
Owner: Do not wait out parking-brake or system warnings while warranty runs down.
2025
Current safety actions cover certain 2022-2025 NX non-hybrids and wider camera/software populations.
Buyer: Run VIN immediately; do not buy around an unresolved stop-sale or open safety action.
Owner: Schedule recall work early and keep the completion record.
Common problems
Faults to check before buying
What fails, what it looks like, what it costs, and the quick checks you can do at the viewing - ranked by how badly each one can hurt you.

Rough running, no-start, warning lights, loss of motive power.
Typical repair cost
USD 0 under recall; USD 700-1,500 retail.
Codes / scan clues
Fuel-pressure, lean and misfire codes.

Quick check
- Run VIN on Lexus and NHTSA.
- Confirm remedy availability and completion.
- Ask dealer about stop-sale status.
- Road-test after repair before accepting car.

Follow Lexus fuel-level instructions before the appointment.
Fault 2
Fuel-hose connector recall on non-hybrid NX
Affects
Certain 2022-2025 NX250/NX350 and related non-hybrid Lexus/Toyota vehicles under 2025 filings.
Symptoms
Fuel smell, leak concern, recall notice, possible fire-risk warning.
Typical repair cost
USD 0 under recall; retail cost varies by hose access.
Codes / scan clues
Usually none unless fuel trim or evaporative fault appears.
Root cause: Fuel hose connector specification concern requiring improved hose replacement.
Quick check
- Run VIN for 25V038/related Lexus action.
- Inspect for fuel odor after drive.
- Ask dealer if parts are available.
- Do not park indoors if fuel smell is present.
Buyer note

Fault 3
Brake booster no-code system malfunction
Affects
2022-2024 NX250/NX350 non-hybrid per L-SB-0034-24 reporting.

- Perform low-speed braking and parking-brake tests.
- Scan with Lexus tools, not generic OBD only.
- Ask Lexus for TSB history by VIN.
Buyer note
A no-code brake warning is still a real brake warning.
Owner note
Photograph the message and make Lexus document it while under warranty.
Fault 4
Panoramic View Monitor / rear camera freeze or blank display
Affects
Many 2022-2026 Toyota/Lexus vehicles with PVM, including NX per recall listings.
Symptoms
Reverse camera freezes, blank screen, parking guide unavailable.
Typical repair cost
USD 0 software recall; USD 500-2,000 if hardware is unrelated.

- Test PVM at startup and after short drive.
- Run VIN for camera recall.
- Confirm software update completion.
Buyer note
Do not accept a blank camera on a car that relies on screens for parking.

Affects
2022-2023 NX 250/350/350h with specified premium sound systems.
Symptoms
Caller hears echo, wireless/wired phone issues, audio faults.

Quick check
- Place a Bluetooth and CarPlay call.
- Ask the other person about echo.
- Check amplifier replacement history.
- Confirm software version.
Buyer note
Test phone calls, not just music.
Owner note
Use the bulletin path early; repeated pairing resets do not fix a bad amplifier.
Fault 6
NX450h+ charging, EV range or fuel-tank complaint
Affects
2022-2025 NX450h+.
Symptoms
Reduced EV range, charging interrupted, charge door issue, fuel gauge/tank capacity complaint.

Fault 8
Rear traction motor cable corrosion / AWD hybrid checks
Affects
NX350h/NX450h+ AWD in wet or salt climates.
Symptoms
