Overview

2018 BMW X4

The 2018 BMW X4 presents a stylish, coupe-like take on the compact SUV segment. It pairs a potent 3.0-liter, 6-cylinder engine with BMW's signature All-Wheel Drive system and an 8-speed automatic transmission. While offering engaging driving dynamics, its "Average" reliability verdict, driven by a critical recall concerning the water pump electrical connector, suggests potential ownership challenges. Buyers should prioritize vehicles with a documented history of maintenance and recall completion.

Critical Failure Risk

A recall addresses an improperly sealed electrical connector on the water pump, which can allow water ingress, leading to short circuits. This can cause coolant leaks, engine overheating, and potential engine damage.

Early detection can help you avoid a $800-$1,500 repair.
