The 2008 BMW 128i has 6 recalls, the most serious being a driver's frontal airbag inflator that can rupture in a crash and send metal fragments into the cabin, posing a risk of serious injury or death.
Two separate filings cover the same airbag inflator defect, and prior repair attempts did not fully resolve the issue for all affected vehicles, which is why multiple campaigns exist. The risk is the same in both: the inflator can explode with enough force to scatter metal shards toward the driver and any passengers.
There are also two fire risks tied to the engine's positive crankcase ventilation system. The heater inside the PCV valve can short circuit and overheat, melting surrounding components and raising the fire risk both while the car is running and after it has been parked and shut off. A separate electrical concern involves the blower regulator wiring harness, where the wiring and connectors can overheat and melt, again creating a fire risk even when the vehicle is sitting unattended. Taken together, the 128i carries three distinct scenarios where a fire could start without the engine running.
Rounding out the list, a fuse and circuit breaker issue in the electrical system can cause a sudden loss of power to the vehicle, which can stall the engine without warning while driving and increase the risk of a crash.
