The 2015 BMW 750Li is a luxury sedan that combines performance with comfort, but when it comes to reliability, it’s a mixed bag. Owners need to be aware that while this vehicle offers a powerful driving experience, it also comes with its share of potential issues that can affect long-term ownership. Understanding the reliability of key components is crucial for anyone considering this model.
Engine Performance
The heart of the 750Li is its 4.4-liter V8 engine, which delivers impressive power and acceleration. However, this engine is known for a few common problems. Oil leaks can occur, particularly around the valve cover gaskets and oil filter housing. Additionally, some owners have reported issues with the turbochargers, which can lead to decreased performance and increased repair costs. Regular maintenance is essential to keep this engine running smoothly, so be prepared for oil changes and inspections.
Transmission Reliability
The 750Li comes equipped with an 8-speed automatic transmission that generally performs well. However, some drivers have experienced rough shifting or hesitation during acceleration. These issues can sometimes be resolved with software updates, but if the transmission starts to slip or show signs of failure, be ready for a costly repair. Regular fluid changes can help prolong the life of the transmission, so don’t skip those service intervals.
Suspension and Handling
The suspension system in the 750Li is designed for a smooth ride, but it’s not without its flaws. Air suspension components can wear out over time, leading to a bumpy ride and potential failure of the system. If you notice any unusual noises or a drop in ride height, it’s time to have the suspension checked. Replacing air struts can be expensive, so keep an eye on this aspect of your vehicle.
Electrical and Other Components
The electrical system in the 750Li can be a source of frustration for owners. Issues with the infotainment system, navigation, and various sensors are not uncommon. While some of these problems can be fixed with software updates, others may require more extensive repairs. Additionally, be aware that the battery can drain quickly if the vehicle is not driven regularly, so consider investing in a trickle charger if you plan to leave it parked for extended periods.
In summary, the 2015 BMW 750Li offers a luxurious driving experience but comes with reliability concerns that potential owners should consider. Regular maintenance and prompt attention to any issues can help mitigate some of the risks associated with this vehicle.
