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 4 tested variants for this model year.
The dominant complaint pattern for the 2011 BMW M3 centers on the engine. Owners most frequently report sudden, unexpected engine shutoffs while driving, some describe the engine cutting out mid-gear change, others report it happening at highway speeds, occasionally accompanied by loud mechanical noise, heavy smoke from the engine bay, and dashboard warning lights illuminating all at once. In several accounts the car became difficult or impossible to accelerate after the event. The airbag system draws the second-highest complaint volume, though the narratives are thinner in detail. A handful of electrical complaints describe the body control module becoming non-functional after battery service, leaving lights, turn signals, and windows inoperative. The recurring thread across the engine complaints is a sudden, unintended power loss with little or no warning, sometimes while the car is already moving at speed.

By System
The 2011 BMW M3 has 4 recalls, the most serious being a defective driver's frontal airbag inflator that can rupture or explode in a crash, sending sharp metal fragments into the cabin and potentially causing serious injury or death.
Two separate filings cover this airbag inflator defect, and prior repair attempts may not have fully resolved the issue for all affected vehicles. On the electrical side, the wiring and connectors that control airflow for the heating and air conditioning system can overheat and melt, raising the risk of a fire even when the car is parked and unattended. There is also a concern with the positive battery cable connection at the fuse box, where the terminal can degrade over time and cause intermittent loss of electrical power, which can stall the engine while driving.
