Summary of Investigation: Welcome to the webpage maintained by Shepherd, Finkelman, Miller & Shah, LLP (“SFMS”), for its investigation of certain Nissan and Infiniti models. Nissan markets its occupant classification system (“OCS”) as part of the vehicles’ safety features. The OCS is supposed to detect weight to indicate that an airbag should be deployed in the case of an accident. Certain Nissan and Infiniti consumers have reported that their airbag warning light was on/flashing, indicating that their OCS are failing to detect weight and deploy in an accident. If you have purchased or leased a Nissan or Infiniti and have experience similar problems with your OCS and airbag warning lights, please contact us below.
