To help 720S owners know what to watch for, we reviewed public records from the National Highway Traffic Safety Administration (NHTSA). For these model years NHTSA has 2 owner complaints on file for the 720S and 2 safety recall campaigns. The most-reported problem areas are suspension (1).
Most-Reported McLaren 720S Problems
These problem areas come up most often in NHTSA owner complaints for the 720S (all model years combined). Complaint counts reflect reports filed, not the share of vehicles affected, so popular and older models naturally have more.

Suspension
1 of the 2 complaints (50%) mention the suspension. Suspension wear shows up as clunks, pulling and uneven tires. We inspect shocks, struts, bushings and joints and align the car after repairs. See our suspension & alignment page.

McLaren 720S Check Engine Codes
NHTSA owner complaints rarely cite specific trouble codes for the 720S, 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 McLaren.
| 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 McLaren 720S Reliable in Phoenix
Arizona heat is the hardest test a McLaren will face. Batteries, belts, hoses, tires and engine oil all wear faster here, and a 720S 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 720S 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 McLaren 720S, a pre-purchase inspection shows what the paperwork does not.
