DBS may fail to activate, leading to insufficient braking assistance during emergency situations.

Variability in engine performance may be noted between the 473hp and 503hp configurations, causing inconsistent driving experiences.

Problems with the ignition system or fuel injectors can cause one or more of the six cylinders to misfire, leading to rough engine performance.

Turbochargers can wear out or fail, particularly in high-performance engines, causing a significant drop in power and efficiency.

Oil leaks are common in high-performance engines, often due to gasket or seal failures, leading to potential engine damage if not addressed.

High-performance engines like the ones in the BMW X4 may experience overheating due to a malfunctioning cooling system, such as a failing water pump or radiator.

The high torque and power output can place extra stress on the transmission, leading to issues such as slipping gears or delayed shifting.

High-performance engines require precise fuel delivery, and any issues in the fuel system, like clogged injectors or a failing fuel pump, can lead to performance problems.

Modern vehicles have numerous electronic components that can fail, including sensors and control modules, which may affect engine performance and reliability.

Performance-focused exhaust systems can develop leaks or become damaged, leading to increased emissions and noise along with decreased performance.

DBS system may not activate or provide inadequate assistance during emergency braking, leading to longer stopping distances.

Inconsistent engine braking performance between the 473 hp and 503 hp configurations.

Potential for misfires in one or more of the six cylinders, causing rough idling and loss of power.

Turbocharger failure or inefficiency can lead to loss of power and increased exhaust emissions.

Common in high-performance engines, leading to potential engine damage if not addressed promptly.

Overheating issues due to inadequate cooling, especially under high-performance conditions.

Can lead to improper engine timing and severe engine damage if the chain skips or breaks.
