Summary

In some of the effected vehicles the active noise cancelation (ANC) and electronic sound enhancement (ESE) features were not activated in the audio control module (ACM). This can cause undesirable powertrain sounds inside the vehicle, and less than optimal speaker sound from ST products, resulting in customer dissatisfaction.
