  Summary

  P57 Interim Repair Procedure Brazil ONLY Some vehicles may experience a Frequency Operated Button Ignition Key (FOBIK) that may stick between the ?START? and ?RUN? position. This may result in the loss of certain electrical features. A FOBIK that is stuck between the ?START? and ?RUN? position while driving could experience an unintended change in ignition switch position to the ?OFF? or ?ACCESSORY? position due to ?FOBIK spring back.? FOBIK spring back to the ?OFF? or ?ACCESSORY? ignition position may result in the loss of certain electrical features and/or a loss of engine power, power steering assist, and/or power brake booster assist. The loss of any of these features could increase the risk of crash under certain driving conditions. FOBIK spring back may also cause the disabling of one or more of the vehicle?s safety features including the frontal airbags. This could increase the risk of vehicle occupant injury during a crash. Chrysler intends to repair the vehicle free of charge (parts and labor). However, the part required to provide a permanent remedy for this condition is currently not available. NOTE: Chrysler is making every effort to provide the part as quickly as possible.
