|---|---|---|---|
| Engine | 23 | 41% | |
| Power Train | 18 | 32% | |
| Electrical System | 7 | 12% | |

Engine
23 of the 55 complaints (41%) 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.
Power Train
18 of the 55 complaints (32%) mention the powertrain. Powertrain complaints can range from rough shifting to loss of drive. We road test, scan for stored codes and inspect fluids before recommending any repair. See our auto repair page.
Electrical System
7 of the 55 complaints (12%) 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.

BMW 750I Check Engine Codes
NHTSA owner complaints rarely cite specific trouble codes for the 750I, 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 750I? 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 750I 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 750I 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 750I 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 750I, a pre-purchase inspection shows what the paperwork does not.
