As an auto owner, understanding the key components and their reliability can save you from unexpected headaches down the road.
Engine Performance
The heart of the 750i is its 4.4-liter V8 engine, which delivers impressive power and acceleration. While many owners appreciate the performance, there are some common issues to be aware of.
Common Engine Issues
- Oil leaks: Over time, gaskets and seals can wear out, leading to oil leaks that require prompt attention.
- Cooling system failures: The cooling system can be prone to issues, particularly with the water pump and thermostat.
- Carbon buildup: Direct injection engines like this one can suffer from carbon buildup on intake valves, affecting performance.
Transmission Reliability
The 750i features a 6-speed automatic transmission that generally performs well. However, there are a few points to consider.
Transmission Concerns
- Shifting issues: Some owners report rough shifting or hesitation, which can indicate a need for transmission fluid changes or repairs.
- Electrical problems: The transmission relies on electronic controls, and issues with wiring or sensors can lead to malfunctions.
Suspension and Handling
The suspension system in the 750i is designed for comfort and performance, but it can be a double-edged sword.
Suspension Challenges

- Wear on components: Bushings, control arms, and struts can wear out, especially if the vehicle is driven aggressively.
Other Key Components
Beyond the engine, transmission, and suspension, there are other areas to keep an eye on.
Electrical System
The electrical system can be finicky, with issues ranging from faulty sensors to battery drain. Regular checks can help catch problems early.
Braking System
The brakes are generally reliable, but be mindful of wear on pads and rotors, especially if you drive in a spirited manner.
Interior Electronics
The infotainment system and other electronic features can sometimes be problematic. Software updates and occasional resets may be necessary to keep everything running smoothly.
In summary, while the 2009 BMW 750i offers a luxurious driving experience, potential owners should be aware of its reliability concerns. Regular maintenance and vigilance can go a long way in ensuring that this vehicle remains a joy to drive.
