Engine Performance
The heart of the X5 4.8i is its 4.8-liter V8 engine, which delivers robust power and acceleration. This engine is known for its smooth performance, but it can be a bit of a gas guzzler.

Keeping an eye on oil levels and addressing any leaks promptly can save you from more significant problems down the line.
Transmission Insights
The 6-speed automatic transmission in the X5 4.8i generally performs well, providing seamless shifts and a comfortable driving experience. However, some owners have reported issues with transmission fluid leaks and erratic shifting behavior. Regular transmission fluid changes are crucial to maintaining its longevity. If you notice any strange noises or shifting problems, it’s best to get it checked out before it turns into a costly repair.
Suspension and Handling

Other Key Components
In addition to the engine, transmission, and suspension, other components like the electrical system and cooling system can also present challenges. Electrical gremlins are not uncommon, with issues ranging from malfunctioning sensors to problems with the infotainment system. The cooling system, particularly the water pump and thermostat, should be monitored closely, as failures in these areas can lead to overheating and significant engine damage.
