NHTSA Complaint #11531204 — 2021 FORD F-150 HYBRID

Our truck is equipped with the B&O Unleashed sound system. One afternoon, upon starting the truck after completing a brief errand, an extremely loud POP sound occured, followed by terrible static and crackling from every speaker. The noises continued for several minutes, even after noticing the audio system was off and then also turning the truck itself off. The terrible noises simply continued. Although the sound eventually stopped, the truck now regularly makes two or three quieter popping sounds as the driver first approaches the truck; nearly every time. The sounds seem to come from the driver door's speaker. There is also faint crackling on occasion from the headrest speakers.
