2013 BMW X1 Sav

For the 2013 BMW X1, the dominant complaint pattern by a wide margin centers on the airbag system, which accounts for nearly half of all filed complaints. Owners most commonly report warning lights illuminating on the dashboard related to the airbag or supplemental restraint system, with several describing the passenger seat occupant sensor as the apparent trigger, the system flags the seat as improperly detecting an occupant's presence or weight. Engine complaints come in at a distant second, where owners describe battery drain issues: vehicles sitting for even a few days lose charge entirely, requiring a jump start, and some report the problem recurring after replacing the battery. A smaller group of engine-area complaints mention an electrical burning smell coming through the vents. Powertrain complaints match engine reports in volume but don't cluster around a single clear symptom.
