Knowing these issues can help you steer clear of these unreliable years.
Active Hybrid System Issues
The BMW 7 Series from the 2009-2015 Fifth Generation has had a lot of problems with its active hybrid system, which raises big concerns about how reliable these cars are. These issues have led to expensive repairs, making these model years tough for potential buyers. If you’re thinking about getting a BMW 7 Series from this time period, keep the following in mind:

It’s really important to do thorough research before making a purchase.
Oil Filter Gasket Leaks
Many owners of the Fifth Generation BMW 7 Series (2009-2015) have had problems with oil filter gasket leaks. This common issue can cause serious engine trouble if not fixed quickly.
In these model years, leaks can lead to oil dripping onto the engine, which is a fire hazard and can result in expensive repairs. To avoid major engine damage, watch for signs like oil spots under your car or the smell of burning oil.
Regular maintenance and quick repairs are essential to reduce these risks. Fixing oil filter gasket leaks right away will help keep your BMW 7 Series running smoothly and prevent unnecessary problems.
Idrive System Problems
Owners of the 2009-2015 BMW 7 Series often dealt with problems with the iDrive system, which affected how well it worked and how dependable it was. The iDrive system, which controls navigation, entertainment, and climate, frequently had issues like freezing or crashing. These problems were quite annoying for users.
Here are four common problems people reported:
- System Freezing: The iDrive system would often stop working and needed to be restarted.
- Software Crashes: Unexpected crashes would interrupt navigation and playing media.
- Slow Response Times: Delays in responding to inputs frustrated many drivers.
- Navigation Errors: Incorrect or outdated maps made route guidance unreliable.
BMW fixed some of these problems in later models, but potential buyers should be cautious when looking at 2009-2015 models.
Sixth Generation (2016-2019)
If you’re thinking about buying a used BMW 7 Series, it’s best to stay away from the sixth generation (2016-2019).
These models are known for having issues like radiator problems and blank instrument clusters. The hybrid system in these cars also tends to be unreliable, affecting their performance and efficiency.
The air suspension, although it gives a smooth ride, often malfunctions and can be expensive to fix. Another big problem is that these cars use a lot of oil, which means more maintenance visits and possible engine damage.
To avoid these headaches and costs, you’re better off choosing a different model year.

These issues can get worse quickly, leading to costly repairs and more downtime.
To reduce the risk of these problems, it’s a good idea to choose later model years within each generation. This will help you avoid the most common engine and cooling system issues.
