Radio change’s channel on its own

[BruceM28]

Recently my radio will change from one preset to another, and back again. I pretty much only listen to Sirius, don’t know if it does it on am-fm. I’ve tried banging on the radio, switching the steering wheel controls back and forth,nothing. There has been no updates done to anything, seems worse when it’s very hot. I have a lifetime extended warranty, but the dealershis is a bunch of clowns. Any ideas?

If it's the 8.4 screen, You can try cleaning the screen with isopropyl alcohol (rubbing alcohol) but it's probably a problem with the screen itself.

2018 + truck with AA/CP radio?

Is there a bubble at the top?

Most likely the Digitizer adhesive between the screen/Digitizer is letting go and causing the issue. Known problem with early 2018-19 Panasonic 8.4 radios due to bad SL01 screen assembly from LG which needs replaced with version SL03 part.

What year is the radio?
is the original to your 2013 truck or an upgrade to the 4c Panasonic with Android Auto/Carplay?

2013 Laramie with the Alpine radio/nav system. Original

Sometimes it will switch to the next preset, sometimes just to the next station numerically

Software does not cause this issue. Screen delamination, steering wheel controls or radio buttons being loose and wiggling on rough road, or other issues with the harware does.

So, the question is, Bruce, does the intermittent station change happen while you're driving and/or sitting stationary?

And, to Ram Forum.

If original 2013 8.4 Harmon radio, then screen delamination is likely not the issue and likely one of the other items that @Dean2 mentioned.

Fyi... There was a recall for 4th gen trucks awhile back where they found that some trucks had the wiring harness inside the wheel pinched in-between covers which caused intermittent issues with cruise control and radio controls like you're seeing.

To help isolate the issue, you could also try unplugging the HVAC/radio Bezel connector temporarily .. That would eliminate the Bezel as the issue and if it still happens, it would suggest the steering wheel controls (or radio, but less likely).

I had that issue with a 2003 Ram that I had. I could tilt the wheel and make the headlights flash.
The problem with this truck is it does it moving or sitting still. I’m pretty sure it’s in the radio itself because I can hit the dash near the screen and it will change, but not always. I will try unplugging that harness and go from there. Just trying to avoid dealer at all costs.

Was that an actual recall or just a TSB?
