Certain vehicles may have a condition in which condensation from the HVAC module can leak into the housing of the active noise cancellation (ANC) module. This can lead to electronic failures inside the ANC module such as erratic audio from the speakers, popping noises, intermittently inoperative, to complete loss of audio. Dealers are to inspect the ANC module for corrosion, replace if corrosion is present, and add a service shield over the ANC module.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2017/MC-10118897-9999.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2017/MC-10118897-0001.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10118897","components":[{"id":"electrical","name":"Electrical system","parent":null},{"id":"software","name":"Software","parent":"electrical"}],"codes":[],"topics":[],"vehicles":[{"make":"GMC","model":"ACADIA","year_from":2017,"year_to":2017,"match":"exact","vehicle_ids":["2017_gmc_acadia"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
