I bought my Gen 3 Raptor this past Tuesday. On Wednesday morning I was parked at a shopping center. When I turned the truck on ... you guessed it ... a loud, explosive boom followed by a pulsing white noise at a higher decibel than any sound I've ever heard! It seriously hurt both my ears, but my son's ears as well. Not to mention the absolute terror it creates. Anyway, nothing would stop the sound. I was surprised the speakers didn't blow, or that the windows didn't shatter. The volume dial didn't work, the power button didn't work, and even turning the truck off and exiting didn't work. It finally shut off when I looked the door (assuming a complete power shutoff at that point).
I restarted the truck five or six more times with the same result. (I did get a video clip of the noise on one attempt.) Only turning off the truck, exiting, and locking the door would stop the stereo each time. Finally, another restart and everything was back to normal. We read some materials online, sensing it may be a bad battery issue. I drove straight to a parts store and replaced my battery. I haven't had another episode in the last two days, but every time I turn the truck on I plug my ears just in case. This is the most insane thing I have ever had happen in a vehicle! Both my ears and my son's ears still hurt. I am they are not permanently damaged.
