The 2008 BMW 3 Series has 4 recalls, the most serious being a fire risk from a crankcase ventilation valve heater that can overheat and ignite a fire while driving or shortly after parking.
On certain M3 models, tires may have sustained cold-weather cracking during transport, where low temperatures caused the tread to crack. A cracked tire can fail at high speed, potentially causing a sudden loss of control. The airbag and seatbelt system also has a concern: faulty crimp connectors on the side airbag and seatbelt pretensioner wiring can create high electrical resistance at the connection point, which may prevent the side airbag from deploying or the seatbelt from tightening in a crash, leaving occupants with less protection than expected. On M3 models equipped with a double-clutch gearbox, the transmission software can trigger an unintended multi-stage downshift during hard deceleration, briefly interrupting power delivery to the wheels and causing an abrupt change in vehicle behavior.

What can fail
Side airbag and belt tensioner wiring may have incorrect crimp connectors that don't make proper contact with their plugs, increasing electrical resistance in those connections.
What the fix does
BMW will replace the crimp connectors on the side airbag and belt tensioner wiring at no cost.

What can fail
During hard braking, the dual-clutch transmission may downshift multiple gears at once, causing the clutch to disengage for about 200 milliseconds. This interrupts power delivery and can cause the engine to stall, resulting in loss of propulsion.
What the fix does
Dealers will reprogram the engine control module to correct the transmission downshift behavior.
