Some customers may state, while using Supercruise, the vehicle
may not stay centered in the lane at times. This may be
described as movement back and forth between the left and
right side of the lane or "ping ponging" behavior.
Anomaly in the lateral control calibration.
Correction:
Engineering is currently working on a software improvement and the PI will be updated or
replaced with a TSB once a determination has been made.
