Official summary
TT: Some customers may experience an abnormal steering sensation (?pulling?, ?drifting?). Condition may be more pronounced with ADAS systems (LTA, LKA, DRCC) turned on or after a cold soak. Steering Angle value displayed in Techstream may be greater than +3° off when the steering wheel is held straight. Every time the vehicle?s battery is disconnected or discharged, the Steering Sensor Zero Point Calibration and Steering Angle Neutral Point memorization must be performed.
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
