Most-Reported Lexus LS Problems
These problem areas come up most often in NHTSA owner complaints for the LS (all model years combined). Complaint counts reflect reports filed, not the share of vehicles affected, so popular and older models naturally have more.

|---|---|---|---|
| Service Brakes | 8 | 28% | |
| Forward Collision Avoidance | 4 | 14% | |
| Engine | 4 | 14% | |
| Wheels | 4 | 14% | |

| Seats | 1 | 3% |
Service Brakes
8 of the 28 complaints (28%) mention brakes. Brake complaints turn up on nearly every vehicle, and Phoenix stop-and-go traffic wears brake parts quickly. We measure pads and rotors, check calipers and fluid, and replace only what is worn. See our brake repair page.
Forward Collision Avoidance
4 of the 28 complaints (14%) mention driver-assistance and stability systems. Driver-assistance and stability systems rely on sensors and software. We scan for stored codes and diagnose sensor and wiring faults. See our check engine light diagnostics page.
Engine
4 of the 28 complaints (14%) mention the engine and cooling system. Engine and cooling complaints are best caught early in Phoenix, where heat pushes cooling systems and engine oil to their limits. We diagnose warning lights and check coolant, hoses and oil condition. See our check engine light diagnostics and oil change & maintenance pages.

Lexus LS Check Engine Codes
NHTSA owner complaints rarely cite specific trouble codes for the LS, 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. |
Got a check engine light on your LS? A code is a clue, not a diagnosis, so we scan it and test the system before replacing anything. See our check engine light diagnostics.

Keeping a Lexus LS 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 LS 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 LS 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 LS, a pre-purchase inspection shows what the paperwork does not.
