NHTSA Complaint #11520599 — 2021 FORD F-150

After driving my vehicle, I parked the truck for about 20 min. Upon returning to the vehicle and leaving the parking spot, a loud crackle and pop sound came from the speaker system. Followed up a recurring static noise that was at the loudest volume I presume the audio system would get to. The static would not cease with turning the volume off, turning down the volume, etc. I tried to turn off the vehicle and leave the vehicle for 5 min but upon restarting the truck, the sound restarted immediately. I tried turning off and restarting 2 more times with no success. I had no choice but to drive 40 min to the closest dealership. The manager and a sales person heard and experienced the sound. They shut the vehicle off and on as I did. They shut off the vehicle for about 10 min while they went in search of a service tech. When the truck was restarted the sound stopped. The tech did a master reset just in case hoping for a error code but none appeared. This event was jarring and a day later, my hearing still is not normal and my ears hurt.
