The DBS system may sometimes fail to engage properly, leading to reduced braking assistance during emergency stops.

Worn control arm bushings, ball joints, and steering components can lead to poor handling and uneven tire wear.

Dynamic Brake Support (DBS) systems can sometimes fail to engage properly, leading to reduced braking efficiency and increased stopping distance.

BMW V8 engines, like the one in the 750i, are known for developing oil leaks, particularly from the valve cover gaskets and the oil pan gasket.

The high-pressure fuel pump in BMW engines can fail prematurely, causing issues such as rough idling, stalling, and loss of power.

Turbocharger failure or malfunction can occur, leading to reduced engine performance and potentially causing smoke from the exhaust.

Timing chain wear or failure can lead to significant engine damage and require costly repairs.

BMWs often experience problems with the cooling system, such as water pump failure, radiator leaks, and thermostat issues, which can lead to overheating.

The 2018 BMW 750i is equipped with numerous electronic systems that can malfunction, leading to issues with the infotainment system, navigation, or other electronic controls.

Direct injection engines are prone to carbon buildup on the intake valves, which can cause rough idling, misfires, and reduced performance.

The automatic transmission in the BMW 750i can experience shifting issues, hesitation, or even complete failure in some cases.

The suspension system, including air suspension components, can wear out, leading to a less comfortable ride and potentially causing handling issues.
