- Problem
- Toyota is recalling certain model year 2012-2013 Scion IQ vehicles manufactured July 31, 2011, through October 12, 2012. The cable for the Occupant Classification System (OCS) may become damaged when sliding the passenger seat forward or backward.
- Risk
- If the cable for the OCS becomes damaged, the front passenger airbags may not deploy or they may deploy inappropriately for the passenger's size and position. This could increase the risk of personal injury during the event of a vehicle crash necessitating airbag deployment.
- Fix
- Toyota will notify owners, and dealers will install a protective cover on the OCS weight sensor cable. The recall began on December 20, 2013. Owners may contact Toyota at 1-800-331-4331.
