Service bulletin PIT5481J

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

This Preliminary Information communication provides information to the technician with additional information on the functionality of Lane Keep Assist. Starting with 2016 model year Lane Keep Assist Regular Production Option Code (UHX) replaced Lane Departure Warning Regular Production Option Code (UFL). Lane Keep Assist is designed to assist the driver in keeping the vehicle from drifting out of a driving lane that has clearly identified markings. The electric power steering provides a gentle steering correction if a lane marking has been crossed and the driver has not actively responded.
