For the 2014 BMW 428i, the electrical system draws the most complaints, with owners describing unexpected shutdowns, power loss, and various electrical faults that can leave the car inoperable. A recurring concern involves the positive crankcase ventilation system, where fluid dripping onto electrical connectors is reported as a trigger for failures. Engine complaints are the second most-reported category, with multiple owners describing sudden stalling or complete engine shutoff while driving, in several cases traced to oil pump failure or oil starvation. Service brake complaints round out the top three, though those reports are less detailed across the set. The oil pump issue stands out because owners describe the car cutting out mid-drive with no warning lights beforehand, and several report difficulty getting parts or resolution from the manufacturer after the failure.
