Service bulletin A451307 2033412-

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Supersedes Technical Service Bulletin Group 97 number 13-35 dated March 27, 2013. Steering wheel does not lock. Various warning lights are on. Steering feels stiffer than usual. The engine cannot be switched off. The ignition key cannot be removed. There are DTC entries present in the system (either static or sporadic). DTCs are stored in the ABS control module. This condition does not result in any drivability concerns. The steering system is fully connected. The insulation for the ABS wheel speed sensor is damaged in production. Over time, this can lead to corrosion on the wires and restricted functions with the ABS control module. Only the wires in the left bulkhead grommet are affected.
