To help M5 owners know what to watch for, we reviewed public records from the National Highway Traffic Safety Administration (NHTSA).

Most-Reported BMW M5 Problems
These problem areas come up most often in NHTSA owner complaints for the M5 (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 | |
|---|---|---|---|
| Air Bags | 69 | 39% | |
| Electrical System | 29 | 16% | |
| Engine | 29 | 16% | |
| Power Train | 20 | 11% | |
| Seat Belts | 11 | 6% | |
| Exterior Lighting | 10 | 5% | |
| Seats | 8 | 4% | |
| Steering | 7 | 4% |
Air Bags
69 of the 173 complaints (39%) mention airbags and seat belts. Airbag and restraint issues are often tied to open safety recalls, which are repaired by the manufacturer at no cost to you. Check your VIN on NHTSA's recall lookup first, and we can help with related warning lights and diagnostics. See our auto repair page.
Electrical System
29 of the 173 complaints (16%) 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.
Engine
29 of the 173 complaints (16%) 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.

BMW M5 Check Engine Codes
NHTSA owner complaints rarely cite specific trouble codes for the M5, 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 BMW.
| 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 M5? 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 BMW M5 Reliable in Phoenix
Arizona heat is the hardest test a BMW will face. Batteries, belts, hoses, tires and engine oil all wear faster here, and a M5 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 M5 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 BMW M5, a pre-purchase inspection shows what the paperwork does not.
