Sometimes when I start my truck the radio will make a loud static for about a second and then stop. This has only happen maybe 6 times in 3 years, so I don’t bother trying to figure it out. Other than the noise, nothing else is affected. Once it made a strange noise and radio started playing music and lost the time. Also, it put a setting back to Audible Touch Feedback on, then whenever I adjust fan on heater/AC it chimes (maybe Audible Touch Feedback is a factory default, might all be back to factory settings and that is the only one I notice). I went and turned off the Audible Touch Feedback and set the time- that was at least a year ago. I should mention I never listen to radio, it has display on of a station and is muted, I can see songs that are playing, time and temp show up in upper right corner, but no sound. If I could I would only have the clock showing, but that isn’t possible. When I hold button and only clock shows up it stays that way until I start truck up next time, then goes to radio on and mute.
Today driving down road I heard a noise, thought I hit something in road like rock threw up under fender or something. Next thing I know the radio is playing, time is changed to 12 o’clock and if I adjust the fan it chimes once again. So Audible Touch Feedback setting went back to on. I should note that the preset stations are not lost.
Now after all that, has anyone experienced something like this or know what could cause this to happen? Now I have set things back to like I normally have them, radio on with sound muted and time and temp in upper right corner. I am sure someday it will do this weird thing of noise again, radio sound will come on, clock will reset and Audible Touch Feedback back to on. Today I did pull out and push back in the radio fuse. Still wonder if a radio issue or something else that affects the radio, because I don't lose preset stations, but lose time and at least one setting of the Audible Touch Feedback goes from off to on. Yet at the same time the radio does come off mute and start playing.
This is on a 2014 Silverado 1500 work truck with 5.3. This is old style, bench seat 2 doors, no power windows or mirrors. Also, there is no bluetooth or anything like that via the radio and is not touch screen.
