Most-Reported Mercedes-Benz AMG C43 Problems
These problem areas come up most often in NHTSA owner complaints for the AMG C43 (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 | |

| Tires | 1 | 100% |
Tires
1 of the 1 complaints (100%) 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.
Mercedes-Benz AMG C43 Check Engine Codes
NHTSA owner complaints rarely cite specific trouble codes for the AMG C43, 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 Mercedes-Benz.
| 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. |

Keeping a Mercedes-Benz AMG C43 Reliable in Phoenix
Arizona heat is the hardest test a Mercedes-Benz will face. Batteries, belts, hoses, tires and engine oil all wear faster here, and a AMG C43 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 AMG C43 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 Mercedes-Benz AMG C43, a pre-purchase inspection shows what the paperwork does not.
