Defect
The Lane Tracing Assist (LTA) function within the driver assistance system uses an improperly configured control program. A deviation in the steering neutral position causes insufficient steering correction by LTA. Depending on curve geometry and vehicle speed, an early warning may activate requiring the driver to intervene manually. This may cause the system to fall out of conformance with Safety Standards Article 11 (steering device). Note: Lane Tracing Assist is a system that assists the driver with steering inputs necessary to maintain lane position while Radar Cruise Control is active.
Corrective action
On all vehicles, the Lane Tracing Assist control computer is reprogrammed to the corrected specification.
