The 2018 BMW 640i Gran Coupe is a car that turns heads and delivers a driving experience that’s hard to beat. However, like any vehicle, it comes with its own set of quirks and potential issues. Owners often rave about the sleek design and powerful engine, but they also share their experiences regarding reliability and common problems. If you’re considering this model, it’s essential to know what you might be getting into.
Common Problems
Electrical Issues
One of the more frequently reported issues among owners is electrical gremlins. Many have noted problems with the infotainment system, including freezing screens and unresponsive controls. Some users on forums have mentioned that software updates can temporarily fix these issues, but they often return, leading to frustration. If you’re not tech-savvy, be prepared for potential trips to the dealer for troubleshooting.
Oil Leaks
Another common complaint is oil leaks, particularly from the valve cover gaskets. Owners have reported that these leaks can develop over time, leading to a mess in the engine bay and potential performance issues if not addressed. Regular checks and maintenance can help catch these leaks early, but it’s something to keep an eye on, especially if you notice any oil spots where you park.
Suspension Problems
The suspension system is another area where owners have voiced concerns. Some have experienced premature wear on components like bushings and control arms, which can lead to a rough ride and uneven tire wear. It’s crucial to stay on top of suspension maintenance to avoid costly repairs down the line. Owners recommend regular inspections, especially if you frequently drive on less-than-perfect roads.
Cooling System Failures
Cooling system failures have also been reported, particularly with the water pump and thermostat. These components can fail unexpectedly, leading to overheating and potential engine damage. Owners emphasize the importance of keeping an eye on coolant levels and temperature gauges. If you notice any fluctuations, it’s best to address them immediately to avoid a more significant issue.
Reliability of Key Components
Engine Performance
On the performance side, the engine is generally praised for its power and smoothness. The 3.0-liter inline-six engine delivers a solid punch, and many owners appreciate the balance of performance and efficiency. However, some have reported issues with the turbochargers, particularly in higher-mileage vehicles. Regular oil changes and using high-quality fuel can help maintain engine health.
Transmission Durability
The 8-speed automatic transmission is another highlight, known for its quick shifts and smooth operation. However, a few owners have experienced rough shifting or hesitation, particularly in cold weather. Regular transmission fluid changes can help mitigate these issues, and it’s worth discussing with your mechanic if you notice any irregularities.
Owner Opinions from Forums
When diving into owner forums, the consensus is that the 640i Gran Coupe is a fantastic car but not without its drawbacks. Many owners emphasize the importance of regular maintenance and being proactive about potential issues. A common piece of advice is to invest in a good extended warranty, as it can save you from unexpected repair bills down the line.
Some owners have shared their experiences with BMW’s customer service, noting that while they can be helpful, the process can sometimes be slow and frustrating. It’s a mixed bag, and your experience may vary depending on your dealership.
In summary, the 2018 BMW 640i Gran Coupe is a stunning vehicle that offers a blend of luxury and performance. However, potential buyers should be aware of the common problems and reliability concerns that some owners have encountered. Staying informed and proactive about maintenance can go a long way in ensuring a positive ownership experience.

From the quality of materials used to the costs associated with maintenance and insurance, here’s a detailed breakdown.
Quality of Materials
When you step inside the 640i Gran Coupe, the first thing that strikes you is the quality of materials. BMW is known for its attention to detail, and this model is no exception.

However, some users have reported issues with the infotainment screen and controls. While the materials themselves are high-quality, the technology can sometimes feel outdated compared to newer models. If you’re someone who values cutting-edge tech, this might be a consideration.
Durability and Reliability
Durability is a mixed bag with the 640i Gran Coupe. The engine and transmission are generally reliable, but as mentioned earlier, certain components like the cooling system and electrical systems can be problematic. Regular maintenance is crucial to keep everything running smoothly.
Many owners recommend sticking to the manufacturer’s service schedule. This includes oil changes, brake inspections, and checking the cooling system. Neglecting these services can lead to more significant issues down the line.
Cost of Insurance
