Fuel economy data from fueleconomy.gov (EPA / U.S. Dept. of Energy). Annual cost based on 15,000 mi/yr at 55% city driving and current fuel prices. MPG is U.S. gallons; L/100km converted. Ranges reflect the 2 tested variants for this model year.
The dominant complaint pattern for the 2013 BMW 128i centers heavily on the airbag system, which accounts for the large majority of the 36 filed complaints. Owners most commonly report the airbag warning light staying on after startup, with several specifically describing the passenger-side airbag light illuminating even when an adult is seated in the front passenger seat. The passenger seat occupancy sensor, the component that determines whether the airbag should deploy for an occupant, comes up repeatedly as the apparent source of the fault, with owners seeing a "fault in passenger restraint system" message. Engine-related complaints are a distant second, spread across a handful of reports without a single dominant symptom emerging. The airbag warning light, particularly tied to the passenger seat sensor, is clearly the most consistent thing owners of this model year describe running into.
