The 2006 BMW 3 Series has 7 recalls, the most serious being three separate fire risks: an overheating PCV valve heater on N52 6-cylinder engines, a corroding blower fan wiring harness that can melt and ignite, and a driver's airbag inflator that can rupture and send fragments into the cabin.
Two recalls cover the same front suspension defect, where a bolt connecting the control arm to the swivel bearing was not tightened correctly during assembly. That bolt can loosen or break, causing a sudden loss of steering stability and raising the risk of a crash. On the airbag side, the front passenger airbag inflator can also rupture and scatter fragments, and separately, a cracked sensor mat under the front passenger seat can prevent the passenger airbag from deploying at all in a crash.
