The BMW 640d Gran Coupe is a stunning vehicle that offers a blend of luxury and performance. However, like any car, it has its share of problems that potential buyers and current owners should be aware of. Understanding these issues can help mitigate risks and ensure a smoother ownership experience.
Engine and Performance Concerns
One of the most significant aspects of the 640d is its engine. While the diesel engine provides excellent torque and fuel efficiency, it is not without faults. Some common engine-related issues include:
- Turbocharger Failures: Turbochargers can fail due to oil starvation or excessive wear, leading to a loss of power and increased exhaust smoke.
- Fuel Injector Problems: Faulty fuel injectors can cause rough idling, poor fuel economy, and engine misfires.
- Overheating: The engine may overheat if the cooling system is not maintained, which can lead to severe damage.
Transmission Troubles
The 640d Gran Coupe is equipped with an automatic transmission that generally performs well. However, some owners have reported issues that can affect drivability:
- Delayed Shifting: Drivers may experience delays when shifting gears, which can be both frustrating and dangerous.
- Transmission Fluid Leaks: Leaks can lead to low fluid levels, resulting in erratic shifting and potential transmission failure.
- Software Glitches: The transmission control module may require software updates to function correctly, as outdated software can lead to performance issues.

- Infotainment System Glitches: The iDrive system may freeze or crash, affecting navigation and entertainment features.
Suspension and Steering Problems
The handling of the 640d Gran Coupe is one of its highlights, but suspension and steering issues can detract from the driving experience:
- Worn Bushings: Over time, suspension bushings can wear out, leading to a rough ride and poor handling.
- Power Steering Failures: Some drivers have reported issues with power steering, including loss of assist and unusual noises.
- Alignment Issues: Misalignment can cause uneven tire wear and affect overall stability.
