For the 2010 BMW 128i, the most consistent theme across owner complaints involves airbags and the restraint system, followed by engine and engine cooling issues. On the airbag side, multiple owners report concerns tied to the supplemental restraint system, with several describing delays in getting a remedy and parts unavailability stretching many months. On the engine side, owners describe stalling at low speeds, loss of power while driving, and rough-running conditions accompanied by a check engine light. A few reports also mention exterior lighting failures, headlights and taillights going dark, alongside illuminated warning lights. Stalling complaints sometimes include secondary symptoms like door and trunk latches becoming unresponsive at the same time, suggesting some owners experienced broader electrical disruption alongside the drivetrain issue.

By System
The 2010 BMW 128i has 7 recalls, the most serious being a driver's frontal airbag inflator that can rupture and send metal fragments into the cabin, causing serious injury or death.
Two separate recalls cover the same airbag inflator defect, and prior repair attempts did not fully resolve the issue for all affected vehicles. On the fire risk side, the heater inside the positive crankcase ventilation valve can short circuit and melt surrounding components, creating a fire risk even when the car is parked and off. Separately, the wiring harness for the cabin blower can overheat and melt its electrical connectors, also posing a fire risk when the vehicle is unattended. There is also an electrical concern where a fuse or circuit breaker failure can cut power to the vehicle entirely, causing an unexpected stall. Rounding out the list, bolts securing a component inside the engine can loosen or break, causing reduced power or a stall that raises the risk of a crash.
