The 2007 BMW 750Li is a luxury sedan that combines performance with comfort, but when it comes to reliability, it’s a mixed bag. Owners often find themselves enamored with the driving experience, but the underlying mechanics can be a source of frustration. If you’re considering this vehicle, understanding its key components is essential to gauge whether it’s the right fit for your needs.
Engine Performance
V8 Powerhouse
Under the hood, the 750Li boasts a 4.8-liter V8 engine that delivers impressive power and acceleration. However, while the engine can provide a thrilling ride, it’s not without its issues. Common problems include oil leaks and coolant system failures, which can lead to costly repairs if not addressed promptly. Regular maintenance is crucial to keep this engine running smoothly, so be prepared for oil changes and inspections to become part of your routine.
Transmission Reliability
Smooth Shifting or Trouble Ahead
The 750Li comes equipped with a 6-speed automatic transmission that generally offers smooth shifting. However, some owners report issues with the transmission slipping or failing altogether. This can be a significant headache, as transmission repairs can be expensive. If you’re buying used, it’s wise to check the service history for any transmission-related repairs or fluid changes.
Suspension and Handling
Comfort vs. Durability
The suspension system in the 750Li is designed for a plush ride, but it can be a double-edged sword. Air suspension components are known to fail, leading to a bumpy ride and costly replacements. If you notice any unusual noises or a drop in ride height, it’s a sign that your suspension may need attention. Regular inspections can help catch these issues before they escalate.
Electrical Systems

Keeping an eye on the electrical components and addressing any quirks early on can save you from bigger headaches down the road.
Other Considerations
