Last night it was -6F when I started my 2015 GMC Sierra. I let it warm up before driving it. I noticed that I had no sound from my radio, turn signals or any other audio devices in the cab. Has anyone else experienced this? After I parked it in the garage for the night everything worked in the morning.

This has been happing with a friends 2015 Sierra as well. He contacted the dealership and told them about the issue. They are putting a new radio in under warranty. The dealership has had about 5 or 6 cases of this in cold weather.

My PDC sensors go hay wire when its below freezing. I can driving down the road and the front sensors show something in front of me for a second then disappear. My truck has 3K miles on but I have a feeling that and the radio is going to need attention.

I'm having the exact same problem.  Can you tell me the name of the dealership your friend went to.  I've had it happen like 6 times, but of course at the dealer twice now and they can't get it to duplicate.  I did video record it 2 times.  Someone from gmc is supposed to be calling .  The name of that dealership might help

I had that issue with my 2015. For a quick fix I would turn off the car, lock it while inside, wait for everything to shut off completely, insert the key and turn it forward to accessory mode(or whatever it’s called) and if the radio turned on I would start it up. If not, I would do the proceed over again. Very annoying especially when in a rush.

My 15 CC same maybe 8 times since new I don’t drive it in the winter. I just turn it off then restart seems to “reboot” everything.

Mine does the same thing only when cold out. Very irritating. I had thought it was my remote start causing this as hadn't heard of many others with this issue but now I see it is quite common. Out of warranty now have just resolved that I have to shut off wait until all lights go out and dash goes black and restart. most times only once but when very cold -5 or so have to repeat a couple times.

This has been  happening to me since day one in the cold. 2015 Silverado now with 92k and out of warranty. Took it to the dealership and they could never duplicate. I used to do the key on/off trick a few times and it would be ok, so I never thought much about it anyways. Now....it is doing it more frequently and I cannot get it to come back even with multiple on/off attempts. Anyone have a real fix?

Did anyone ever find a fix for this? I live in Anchorage, Alaska and drive a '15 Silverado.  Every time my truck sits out overnight when it's colder than 10 degrees, I have this issue the next day.  Since this does seem to be a relatively common issue, I contacted my dealership service to see if they'd had any other complaints of the same problem.  They said they had not, which was surprising considering the colder temps up here. I had read on another forum that replacing the radio unit may fix the problem, but I was hoping to get some confirmation on that before I spend the money to do that.

i too started having this problem with my 2015 sierra. after driving a bit and warming it up. park to run into a store, come out and start and it works.
i never tested initial starting by key, always the remote to first start and key for second start.

FARM FIX:: I have the same problem with 2015 sierra. When it’s truck has sat in cold overnight the radio doesn’t work and my turn signal doesn’t make noise. If I pull the 20A radio fuse on right side of dash/passenger door, wait couple seconds and put fuse back in the radio works fine. Pain in butt yes, but cheaper then taking to shop.

      Oil Consumption

      By Chuck FB · Posted

      So speaking of oil consumption with my L8T as I just changed the oil yesterday and made the switch over to Amsoil SS 0W-40 from the Mobil 1  5W-30 Truck and SUV I just dropped out. 2900 miles on that oil as well as  68 hours on that oil ( so used to equipment with an hour meter and that becomes valuable information to compare with others as well ). Once again the oil use was so very little, I am going to say it dropped under 1/16 of an inch on the dipstick. No towing was done and this interval was from early spring until now.    One interesting item to note is that going by the 5 quart jugs I was using before from Mobil, it was showing that I was putting in 8 US quarts to bring it to full if not slightly over the full mark according to their jug markings. Granted I did allow more drain time this time and in part because the engine oil was only lukewarm as I started it and let it idle and not for long enough to get the oil itself hot ( the engine was up to operating temp ). The oil in that state just seemed to take forever for it to drip out but not only at the drain plug but at the oil filter housing as well, perhaps I had never quite gotten all the oil out before and I could have still waited longer but as it was I waited well over 3 hours. I think next time if I have the time I will do an experiment by dropping the oil and lets say leave the pan under it for 15 minutes, then switch to another pail and let it drip out overnight and measure how much more oil comes out. So this time and yes I ended up getting it just over the full mark as I was experimenting with trying to get the level to the add mark after I had run it and then waited some and then added a bit and waited for a certain amount of time for it to settle to the add mark. I very well may not have waited long enough for that experiment but I got to the add mark, then dumped in a full quart and waited some and checked and then waited some more and it crept up more ... and then finally oops, it was slightly over full some hours later when it really had settled all it would. I find this engine sure takes time for the last bit of oil that gets poured in to finally make its way into the crank case. I can only guess at how much too much I added as per maybe a 1/10th of a quart. I had poured in 8.5 quarts going by the quart containers as per 8 quarts and 16 us ounces. I was shocked at how much this was off compared to the prior oil changes and if those larger jugs and they are not marked accurately enough or they contain slightly more than what they say, or the drain time factor made that much of a difference. But I know on this forum there have been others who have said they have put well over 8 quarts in their L8T and now I have also going by the Amsoil true quart containers. Its a confusing convoluted mess up here in Canada with some oil manufactures packaging is in true US quarts, some is also in true US quarts containers on an even number of quarts but also marked in liters which becomes the odd ball volume of a fractional amount of liters. Then there is the Liters only containers, no US markings as its a true metric container and only measured in Liters to an even number of Liters. But remember we used to have Imperial Gallons and Imperial quarts as well !.

      Holy smokes. Clearly not a deal on that truck. I just mean in general, matte or painted trim is becoming more normative than chrome, but I know the Black Optics packages on various vehicles are being sold as uplevel trims. They look really good, but sheesh. It's just paint and plastic.

      I Wouldn't Know Where to Begin    Oh I know where I would begin but I'm just one of over eight billion people on this rock. Eight billion versions of where the goal post is. How large it should be. How far to kick from. What ball is the right ball. Elevation. Age.....are you getting the point? It isn't about disagreeing with one individual. It's about agreeing only with one individual. One's self.   Agreement comes when multiple people hold the same point already. THAT is the goal of an education. Building the Social Contract. That thing that allows us to all read this sentence. We've agreed on the alphabet and how to arrange those letters into words we agree upon whose meanings hold true for everyone entering into that contract. Those words arranged into a sentence form an idea and several sentences strung together in a paragraph convey an argument for or against or inform the reader of a state, condition or perhaps reveal a things nature. Paint a word picture. Make oneself known.    This contract is not limited to words although they are often explained by words. Things like numbers and their usefulness. Physics, Chemistry, Medicine, Music, Art and so on.    The frequency of middle C (C4) is 261.63 Hz is a first principle. We build on that to make music we all can enjoy even if we all can not compose or play. You don't have to master it to make it enjoyable and useful.    So why is the Beginning so difficult? Why is agreement so elusive?   Everyone "Signs" the contract (when receiving that education in obtaining it)  but fewer and fewer in this world have any intention of living by that contract. They find exploiting that contract more advantageous. Disruption. With intent. Without intent. In Ignorance. In your face. With a double dog dare you. With a hold my beer. In resistance to that contract and in spite how it looks on us. It permeates the very air we breath.    In this way the contract is subject to advantage. Abide by it when it serves you, disregard it when it doesn't. Unpredictable and self-serving. Corrosive.....Toxic........   It says a lot about a persons character to disregard the contract, the truth, first principles. None of it good.        ********************************************************   https://medicine.yale.edu/news-article/character-vs-personality-who-we-are-and-who-we-aspire-to-be/   Just an interesting article.

      It costs $5,250 for the Yukon Nightfall option (black wheels, emblems and illuminated black GMC grill badge). What a "deal".

      I keep getting the above error message on my 25 Sierra.  If I reset the infotainment unit (via the phone hang up button) it will work again for a day or 2.   But I dont want to do have to reset  all the time. Works fine in my 2023 Corvette. On both vehicles I connect wirelessly.   I have a Google Pixel 10 Pro XL, phone is up to date.  Any Ideas.  See attached
