The 2004 Mitsubishi Lancer has 6 recalls, the most serious being a passenger-side frontal airbag inflator that can rupture during deployment, sending metal fragments into the cabin and raising the risk of serious injury.
This airbag defect has been the subject of multiple repair campaigns over the years. Moisture can work its way into the inflator over time, building pressure that causes it to explode rather than deploy normally. Prior repair attempts using a like-for-like replacement inflator did not fully resolve the issue, and vehicles that received that interim fix are included in a subsequent recall requiring a complete remedy. The defect can also damage the airbag module itself, which may prevent the bag from deploying at all in a crash.
On the chassis side, the front lower control arms can detach from the suspension. If a control arm lets go while driving, the affected wheel loses its connection to the steering and suspension geometry, and the driver loses the ability to steer or control the vehicle.
