Most-Reported Lexus RC 300 Problems
These problem areas come up most often in NHTSA owner complaints for the RC 300 (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 | |
|---|---|---|---|
| Vehicle Speed Control | 1 | 33% | |
| Fuel/Propulsion System | 1 | 33% | |
| Visibility/Wiper | 1 | 33% |
Vehicle Speed Control
1 of the 3 complaints (33%) mention vehicle speed control (throttle and cruise control). Speed control complaints involve the throttle, cruise control and related sensors. We scan for stored codes and test the throttle system and sensors to find the actual cause instead of guessing. See our check engine light diagnostics and auto repair pages.
Fuel/Propulsion System
1 of the 3 complaints (33%) mention the fuel system. Fuel system problems can cause stalling, hard starts and poor mileage. We test fuel delivery and related sensors to find the real cause. See our no-start diagnostics and check engine light diagnostics pages.
Visibility/Wiper
1 of the 3 complaints (33%) 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 RC 300 Check Engine Codes
NHTSA owner complaints rarely cite specific trouble codes for the RC 300, 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 RC 300? 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 RC 300 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 RC 300 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 RC 300 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 RC 300, a pre-purchase inspection shows what the paperwork does not.
