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 2010 BMW M3 centers on airbags, specifically owners reporting that a remedy for a known airbag inflator issue was unavailable due to parts being on backorder, with multiple owners describing extended waits and frustration getting repairs completed. Those complaints account for more than half of the total filed for this model year. On the engine side, a handful of owners report connecting rod bearing failures, describing symptoms like a ticking noise on startup after the car has sat, followed by metal shavings found in the oil. Owners in that group attribute the failures to oil starvation in a tightly-toleranced engine, though the bearing issue appears in only a few reports compared to the airbag backlog complaints that dominate this vehicle's complaint record.

Crash-Related
By System
The 2010 BMW M3 has 4 recalls, the most serious being a Takata-style driver's frontal airbag inflator that can rupture and send metal fragments into the cabin, risking serious injury or death.
The airbag inflator defect is well-documented across a wide range of BMW models from this era: the inflator can explode with enough force to scatter sharp metal shards toward the driver and other occupants, both in a crash and potentially without one. Prior repair attempts did not fully resolve the issue for all affected vehicles, which is why multiple recall campaigns address the same underlying problem.
On the electrical side, there are two separate concerns. The connection between the positive battery cable and the fuse box terminal can degrade over time, causing intermittent loss of electrical power. When that happens, the engine can stall without warning, leaving the driver without power steering, power brakes, or engine response mid-drive. The other electrical issue involves the wiring and connectors that control airflow through the heating and air conditioning system. That wiring can overheat and melt the surrounding connectors, and in some cases can progress to a fire, even when the car is parked and unattended.
