NHTSA Complaint #11487857 — 2022 FORD F-150 LIGHTNING BEV

On October 4, 2022 at ~1:30 p.m. EDT I was stopped at a red light when an extremely loud pop and deafening noise "exploded" in the truck cabin. If I had been driving at the time, the sudden and extreme noise could have caused me to react in a way to lose control of the vehicle. After the light changed, I turned into a business entrance, turned the vehicle off, got out of the vehicle, locked the door, and the noise still continued for several seconds. After the noise stopped, I got back in the vehicle, restarted it, and the noise returned. The noise sounds like it is coming from the sound system at more than full volume. I estimate the sound level at well over 100 dB. Trying to turn off the sound system had no effect on the problem. I had to drive my truck for at least 20 minutes to get home with the deafening noise continuing unabated for the entire trip. After about 10 minutes into the trip, I also detected an "electrical burn" smell in the cabin. The smell was strong enough that I looked around the cabin for smoke, but I did not see any. Something has definitely overheated. Two hours after the incident my ears are still ringing, and I have a severe headache. I am a retired Licensed Professional Engineer with over 50 years of Engineering and Safety experience. I did not notice any warning lamps or messages. The vehicle seemed to operate normally, except the air conditioning system seemed to be operating at reduced capacity. This issue has been reported by at least 50 members on the "f150gen14.com" forum.
