The 2021 BMW X5 xDrive40i is a luxury SUV that combines performance, comfort, and technology. However, when it comes to reliability, it’s crucial to dig deeper into its key components. As an auto owner, understanding the reliability of the engine, transmission, and suspension can help you make informed decisions about maintenance and potential issues down the line.
Engine Performance
The heart of the X5 xDrive40i is its 3.0-liter inline-six engine, equipped with BMW’s TwinPower Turbo technology. This engine is known for its smooth power delivery and impressive torque. While it generally performs well, some owners have reported issues with oil consumption and minor leaks. Regular oil changes and monitoring fluid levels can mitigate these concerns, ensuring your engine runs smoothly for years to come.
Transmission Reliability
The 8-speed automatic transmission in the X5 is designed for seamless shifting and responsiveness. Most drivers find it to be reliable, but there have been occasional reports of rough shifting or hesitation during acceleration. Keeping the transmission fluid at the right level and changing it according to the manufacturer’s recommendations can help maintain its longevity.
Suspension and Handling
The suspension system in the X5 xDrive40i is engineered for a balance of comfort and sportiness. It features an adaptive air suspension that enhances ride quality. However, some owners have experienced issues with air leaks in the suspension system, leading to a drop in ride height and comfort. Regular inspections and addressing any warning lights promptly can prevent more significant problems.
Electrical Systems
Modern vehicles are heavily reliant on electrical systems, and the X5 is no exception. While many components work flawlessly, there have been reports of glitches in the infotainment system and occasional sensor malfunctions. Keeping the software updated and addressing any electrical issues quickly can save you from more extensive repairs later on.

The braking system in the X5 is robust, featuring large disc brakes that provide excellent stopping power. However, some owners have noted premature wear on brake pads and rotors, especially if the vehicle is driven aggressively. Regular brake inspections and using quality replacement parts can help maintain braking performance.
