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 2011 BMW 328i centers on the engine, which draws the heaviest complaint volume by a wide margin. Owners frequently report unexpected stalls, sudden loss of power, and the engine shutting down while driving, sometimes at highway speeds and sometimes with little or no warning light beforehand. Low oil pressure warnings appear across multiple reports and are often tied to stalling events that leave the vehicle unable to restart without a tow. A recurring diagnosis mentioned by owners involves the VANOS system's hardware failing, though fuel delivery problems also come up, with several owners describing the fuel pump or its control module cutting out and killing the engine mid-drive. Idling issues, including RPM fluctuation, rough idle, and a burning smell at low speeds, show up as a secondary cluster within the same engine category.

With Injuries
By System
The 2011 BMW 328i has 5 recalls, the most serious being two separate airbag inflator defects where the driver's airbag can explode during deployment and send metal fragments into the cabin, posing a risk of serious injury or death.
Two recalls also involve fire risk. The heating element inside the crankcase ventilation valve can short circuit, melting internal components and potentially starting a fire even while the car is parked. Separately, the wiring and connectors that control airflow for the heating and air conditioning system can overheat and melt, also raising the risk of fire when the vehicle is unattended. One recall only affects xDrive models: front driveshaft attachment bolts on certain vehicles may not have been tightened to specification, and if they work loose, the front wheels can lose drive power and the vehicle may break down unexpectedly.
