Narrative:
After cleared to intercept runway 35C localizer, the autoplt did not intercept localizer final, resulting in an overshoot. As we corrected back to final. ATC advised us of the overshoot and gave us a new heading and altitude to reintercept. We continued to an uneventful approach and landing.
