Unexpected adaptive cruise control braking	C-CM Front bumper cover	The adaptive cruise control system can occasionally detect and respond to out-of-path vehicles, especially on curves, entry/exit ramps or when changing lanes. CHECK the C-CM and front bumper cover for damage. RETEST the adaptive cruise control system.
Lack of adaptive cruise control braking	C-CM Front bumper cover	The adaptive cruise control system may not detect and respond to vehicles carrying out close cut-ins or on tight curves (especially for vehicles on the passenger side) due to limited C-CM field of view. CHECK the CCM and front bumper cover for damage. If no damage is observed, RETEST the adaptive cruise control system.
Noise during adaptive cruise control braking	Low speeds Brake concern	The driver can detect some noise at low speeds when adaptive cruise control braking occurs. If braking noise continues, REFER to BRAKE SYSTEM - GENERAL INFORMATION to continue diagnosis of the ABS system.
