Known issues on the 2013 Sentra. Six recalls are on federal record for this model year. One covers a front passenger seat belt bracket that can deform when used to secure a child restraint, causing the Occupant Classification System to misclassify the seat and leave the frontal air bag from switching off as designed. A second covers Occupant Detection System sensors built out of specification, which can permanently suppress the passenger air bag. A third covers electrical system software that can have the same OCS incorrectly read the passenger seat as empty when an adult is sitting in it. A fourth covers an incorrectly installed OCS control unit from a prior repair, causing the same empty-seat misclassification. A fifth covers the OCS again, where the front passenger air bag may not deploy as intended in a crash. The sixth covers the fuel tank assembly: some units built between September and October 2012 were not properly sealed and can leak gasoline when the tank is full, raising fire risk near an ignition source. Owners have filed 638 complaints for the year. The factory diagnostic and repair procedures behind each of those systems are here.

Whether you're tracing an OCS fault code, inspecting the fuel tank seal, or working through a routine service interval, it keeps you on the OEM procedure and the correct specification for your specific 2013 Sentra.
