Audio goes silent by wiping the dust off the dash?!?!?!

long time listener, first time caller...

 

I have a 2015 Silverado with the 8" screen with the I05 hmi module and have the weirdest issue I have ever seen.

 

While driving or at a stop light, if I wipe the dust off the dashboard with my hand directly over the radio (the high hump in the dash right in front of the light sensor), all of the audio goes silent. No radio, turn signal clicks, no phone, etc. The radio is still on, but nothing. Power cycling does nothing, but shutting off the truck and waiting 5-10 minutes works.

 

I assume the static electricity does something?? It is just simple wiping of the hand on the plastic dash, not banging or moving the dash.

 

I did it accidentally the first time, and have been able to do it 2 other times. It's not every single time, but is semi-repeatable. I'm taking it into the dealer soon, but I'd like to know if anyone else has had this.

 

Thanks!

Welcome to the group, I have never had this happen or heard of anyone else having this issue. Sounds like you need to quit dusting! :lol:

That's what I'm assuming the recall will say...

 

"customer should avoid visible micro particle removal from horizontal dashboard surfaces while listening to audio playback or using turn signals" :nopity:

Wow, this is one for the books, Take it to the dealer and get a new HU?

Indeed... This issue would normally be irritating, but it's so random that it's almost funny.

 

I have an appointment tomorrow. Hopefully it will do it for me when I'm there. Otherwise, I'll sound like a complete loon...

2015 Sierra exactly the same problem. Any word from your dealer?

Truck is in the shop now. Fortunately... I was able to re-create the issue in the service department.

 

The service tech had to call the main GM technical support center, and from what I've heard so far, There is an electro-magnetic interference caused by the static electricity caused by the swiping on the dash. They have to wrap a certain wiring harness in a special foil tape and relocate it.

 

For kicks, I tried to do it to the truck in the showroom, but no luck.

 

Hard to believe - over a million miles of testing, and no one ever dusted the dashboard?? :driving: The test trucks must have been nasty when they where done!

 

If there is any specific info when I get the truck back, I'll post it.

Mine has done what you are describing but with out swiping the dash. At first when the truck was new, I chalked it up to me messing it up somehow, not knowing what I was doing. Then I figured it out, and I wasn't messing anything up, because it was all just muted, but still had display, buy obviously not acutally muting the system. I'd shut the truck off for a few minutes, and the sound would be back. However, this hasn't happened in a couple months. I am gonna go try and wipe my dash.

Let me know if the dealer puts a TSB number on your invoice just in case I have this problem. Thanks!

At least you were able to recreate it! Thats like finding a needle in a haystack.

 

Hopefully they get you all straightened out.

If the cables can be idetified, one could wrap them with metal tape used in duct work to shield said cables from interference?

      This is a really late reply but I just found this thread. They won't sell the hinges. I've gone 7 rounds with them. Their solution is to buy a new cover. I'm about to buy a new cover and it won't be a Bakflip. It also won't be from realtruck.com.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Yes, and also pulling heavy trailers or a large camper up steep grades as well as descending grades such as the more rustic off road camping locations and using engine braking with that low gearing as well as soft ground can just suck the power . I realize pickups these days tend to have an over all lower first gear ratio compared to automatic transmission pickups from years back so that has helped a lot in its ability in high range but there comes a point if in four wheel drive the torque runs out at the wheels, certainly with a gas engine. They don't put two speed transfer cases on pickups for a cool factor, they have a function if one needs that massive torque to the wheels that high range can't deliver.

      Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....

      Gas Prices

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.
