Most-Reported Lexus NX Problems
These problem areas come up most often in NHTSA owner complaints for the NX (all model years combined). Complaint counts reflect reports filed, not the share of vehicles affected, so popular and older models naturally have more.
| Problem area (NHTSA component) | Complaints | Share | |
|---|---|---|---|
| Electrical System | 4 | 22% | |
| Wheels | 2 | 11% | |
| Visibility/Wiper | 2 | 11% | |
| Seats | 2 | 11% | |

Electrical System
4 of the 18 complaints (22%) mention the electrical system. Electrical problems are made worse by desert heat, which ages batteries, cables and connectors. We test the battery, starter and charging system and trace faults to the actual part. See our battery replacement and starter & alternator repair pages.
Wheels
2 of the 18 complaints (11%) mention tires and wheels. Tire and wheel complaints are often about wear, vibration or pressure warnings. We check tires, balance and alignment, which matters in Phoenix where heat accelerates tire wear. See our suspension & alignment page.
Visibility/Wiper
2 of the 18 complaints (11%) mention lighting and visibility. Lights, wipers and visibility items are quick to fix and are on every rideshare inspection checklist. We check them as part of our inspection prep. See our rideshare inspection prep page.

Lexus NX Check Engine Codes
NHTSA owner complaints rarely cite specific trouble codes for the NX, so we do not have a model-specific ranking to show. These are the check engine codes we see most often on vehicles in Phoenix heat, and any of them can show up on a Lexus.
| Code | What it means |
|---|---|
| P0420 | Catalyst efficiency below threshold (bank 1) Often a worn catalytic converter, but failing oxygen sensors or exhaust leaks can set it too. Can cause an emissions test failure. |
| P0300 | Random or multiple cylinder misfire Worn spark plugs, failing ignition coils, fuel or vacuum problems. Do not ignore a flashing check engine light. |
| P0171 | System too lean (bank 1) Often a vacuum leak, dirty MAF sensor, weak fuel delivery or a failing oxygen sensor. |
| P0455 | EVAP system large leak Missing or loose gas cap, or a disconnected or cracked vapor hose. |
| P0128 | Coolant temperature below thermostat regulating temperature Usually a thermostat stuck open. Fix it to restore efficiency and cabin heat. |
| P0442 | EVAP system small leak Loose or worn gas cap, cracked hose or purge or vent valve. |
| P0301 | Cylinder 1 misfire Commonly a bad spark plug or ignition coil on that cylinder. |
| P0401 | EGR flow insufficient Clogged EGR passages or a stuck EGR valve. |

Keeping a Lexus NX Reliable in Phoenix
Arizona heat is the hardest test a Lexus will face. Batteries, belts, hoses, tires and engine oil all wear faster here, and a NX that spends its life in stop-and-go Valley traffic needs maintenance earlier than the owner's manual's normal schedule suggests.
Our recommendation for NX owners: follow the severe-service schedule, test the battery before every summer, inspect brakes and tires twice a year, and have any warning light diagnosed instead of ignored. If you are shopping for a used Lexus NX, a pre-purchase inspection shows what the paperwork does not.
