I do not have SXM signal in my 17 GM 1500, there is a hardware failure between the head unit and SXM.  Had it in today and the entire unit was replaced.  Updated the ID # with SXM and still nothing.  I did check the shark fin, water came out from beneath it when I put pressure on the fin.  I'm not sure if that impacted anything.  Funny that I had no issues with my previous GM truck and this one is a year old and kaput.  SXM resent my info several times, nothing.  Error is no signal and something about signal blocked.  I only see channels 0 and 1 and no preview.

Agriont:  I have the same "Reception Blocked" problem.  I had a trial on my 17 Suburban.  I renewed my subscription for 4 months last week and it played one day.  After that I refreshed the signal, moved the car, the reception is blocked.  Sirius says go to the dealer.  Frustrated.  Well I am only out $25

The radio head unit was replaced under warranty.  Didn't resolve the problem.  Next step was to replace the antenna unit, which includes the fin.  Seems GM has those pre-painted in stock based on your VIN.  The antenna was the problem for my vehicle.  I note though that the break in the seal is at the front of the fin vice the rear with the old and faulty unit.  SXM wanted to charge me to transfer to the new SXM ID #, told them to pound sand.  Everything works fine now but the antenna is not as good as an aftermarket, portable kit magnet type.  I don't think that there are any bulletins or recalls but the radio is part of the vehicle.  Go to the dealer and have them fix the problem because it is the equipment that is the problem

It's GM's problem but they are trying to blame the signal with me as well. I can switch to an aftermarket antenna and it works perfectly. I've also had a 2008 Avalanche, a 2015 Acadia and a 2017 Acadia that have no issue. Only my 2017 Sierra Denali cuts out.

You certainly confirmed what a lot of us suspected...crappy antenna signal. Where is your aftermarket antenna mounted? Thanks for the video and welcome to the site!

I ran it through the dash and it's right behind the normal antenna on the Passenger Side Fender. It's just the old antenna that I got in 2005 with my very first Sirius Kit my wife bought for my truck.

 

I made another video that I haven't uploaded to youtube of me driving through an area where it is cutting out constantly and then I switch antennas to the aftermarket and it works perfectly. Basically, the same as above just a lot more driving.

 

Initially, the dealership tried to argue it wasn't GM's problem and that it was just bad reception in town. They attempted to convince me by telling me they took trucks like mine out and got the same result. I told them that the only confirmed my suspicion that this is a much bigger issue affecting a lot of trucks. Once I showed them this video and reminded them that I've had 4 factory Sirius XM equipped GM vehicles and this in the only one that did it they were more helpful. IMO my dealer did what they could and replaced the original antenna.

 

I have since gone directly to GMC but so far, I'm getting nothing but "Customer Service" talk. Lot's of apologies and no action. They want me to take it back to the dealer and tell them to fix it. I've nicely and NOT so nicely explained to them the dealer has already done what they can. I think they really just don't want to admit it is on their end because then they are going to have a very wide spread issue. I have also requested to speak directly to engineering. I am also an engineer and would love for someone at GM to tell me why I am wrong in face of all the evidence I've presented.

I feel sorry for SiriusXM...I know a lot of us just said screw it, never went past my 3 month trial with the crappy reception.

It was a good idea at the time. With Pandora, I-heart radio, and even I pods there's just no reason for it. Who wants to listen to music you don't want to get to music you do in this right now world. And the sound isn't as good. Their billing procedure don't get me started, just like dealing with direct tv.

That's a good point. Had not thought of it from SiriusXM's perspective but that might be because I've had Sirius/SiriusXM for so long I knew how it should work and never considered it was anything but an issue with the truck.

 

One thing I am considering trying is going to test drive an F-150 and driving it around town to see if it's better or not. If so then my next video can be of my GMC vs a Ford Satellite Radio Reception comparison.

Never had a problem on my 2008 Avalanche, I barely lost it inside the Mobile tunnel. This truck is atrocious. XM ought to get on GM to get their stuff together! XM is losing a ton of money from people like me not renewing with them, it’s a complete waste of money with the system/antenna I have.

Ahh but there are other happily satisfied customers of other auto makers subscribing to XM all the time, so no big deal to them.

I enjoy having the XM Radio but that’s all. I think, not totally sure, I pay approximately $140 per year for two cars and it comes with weather mapping as well but never use. IMO, 140 is pretty good for two cars. I also have Apple (unlimited) radio but my wife really enjoys listening to the news while driving. I’m just trying to keep up with all the new music my kids are listening too. Btw, the other day I asked my kids what they were listening too and the reply was “Marshmallow”, who and what the heck is Marshmallow?? Lol, man times are definitely different......

 

And so many just don’t get it and forget about the mental diseases plaguing our country lol

I enjoyed it and didn’t mind paying for it but this truck just doesn’t receive it well at all. It’s all I listened to in the Avy

I just got this message from GMC after I ranted on the phone at this poor Christian guy this morning.

I am very much not done with this yet. I feel like I'm orbiting the earth with a Flat Earther, showing them the curvature of the Earth and they are just going "Nope, Nope, I don't see it." 

 

I'll spare you guys my response to this message.

    • 286,740 Mile Services   8/6/2026   New AC Compressor. Refrigerant oil and dye, evacuate and charge system.  New exhaust system from cat back.  New Iridium plugs plus replace #3 coil Repair/rewire headlamp wiring (passenger side) and replace all forward bulbs. Polish lenses of both assemblies.  Pull rear rotors, clean and adjust parking assembly. Inspect, clean and grease front calipers. Check pads and shoes.  4 wheel power bleed of brake system. Dot 4 Reset idle speed 50 rpm higher New Serpentine belt.    Will need new pads in the rear in about 5K more miles.    Tax Title and License out the door just short of a grand.    AC clutch had bitten the dust. 1 year warranty on the pick and save replacement. Thing will make a Polar Bear cry Uncle.  He spent quite some time on the wiring. It was in the harness and he does nothing half. I got off cheap. I have considerable more light down the road. Sylvania Silver Star replacements.  Gas seal between the porcelain and shell of plug #3 was blown, cooked the coil. That was the cold miss.  Love the new exhaust. I can sneak into the neighborhood again.  Nice to have a working parking brake again. Belle Tire never got it done. That was disappointing.    This was one of her bigger bills and still way cheaper than a payment even given the oil consumption. This thing cost me under a hundred a month in repairs and normal routine costs. What is my incentive to replace it? 🤔           
    • hello I recently bought a 2012 gmc 1500 with a 5.3 and have a AFM disabler on it I'm interested in doing a cam but I'm worried if I remove the AFM system I will fail smog does anyone have info if they are able to detect that or a work around to it (not talking about hot smogging) please let me know thank you  
    • Update. I started chasing down my symptoms. Started first with pulling valve covers and looked at everything. Everything looked good and couldn't hear or feel anything different. Then a compression test. 240 psi or really close on each cylinder. I was worried I was a tooth off of timing. Not bad for an engine with 173,000. Granted I did put new heads on. I sprayed water around the injector area to see if I could hear a change. Nothing. I hooked up my new hp tuner which I should have done in the first place but I don't really know what I'm looking at just yet but am learning. I noticed the fuel trims were way off so that told me I have to have either a bad injector or exhaust leak. New injectors, so I did the shop vac on blower and in the tail pipe. Sprayed soapy water and found the exhaust flange on the drivers side was leaking. I didn't think it would be that considereding I pulled the heads and left the manifolds attached. I did have the transmission replaced not long ago. They must have not seated them properly but I guess I didn't notice. I put in new gaskets on both sides. Which by the way isn't a bad job but I had a hard time getting them to seal right. Took two attempts. Reset the fuel trims and the ticking is gone, engine runs smooth and acceleration has improved. Got to feel the real difference with that stage 1 cam. It's not that big of a difference but it does add a little more. It feels like how the truck should have been from the factory.
    • Can it still be Assembled I?    Stribeck says that we need a certain amount of viscosity under conditions of load and velocity to prevent two surfaces of a know roughness from tearing each other asunder. And we have marketing trying to tell the masses that those two surfaced require less of that commodity due to more exact limits being placed on the same old clearances. We also know that there are limits to how hard something can before it becomes to brittle to be viable and to smooth to 'wet' the surface and that both of those conditions have been known and met since about the Second World War.    That viscosity value shook out at 10 centistokes at 212 F just under a hundred years ago.  Give this a look: [Anton Parr]     What is advertised is the Kinematic viscosity (mm2/s) or that which has been density adjusted but the value we are after is the dynamic viscosity (mPa.s) or true viscosity. You can see that this number is dependent on density thus base stock and temperature. You can also see that an SAE 30 doesn't reach that value in this example. However an SAE 30 that is at the upper end of the SAE 30 range; 12.5 cSt (mm2/s), might. 12.5 * .83 = 10.375 (mm2/s). If you could find an SAE 30 at the upper end these days.   Then there is the complication of viscosity modifiers or VII or VM, whatever you wish to call them. Polymers added to very thin base oils, perhaps 3 to 6 cP oils, that will meet the SAE *W30 spec at 'tested' shear rates and 100 C/212F  target temperature. So a polymer fortified base that is a fraction of the 10 cP requirement Stribeck insist upon.   This could be all well and good if those polymers didn't have two very problematic 'features'. They shear or loose viscosity both 1.) permanently and 2.) temporality. And they do both omitted in the advertised data with the distinct  purpose of deceiving the consumer of the actual operating state of the fluid. I've shown the example of Warren Oils COSTCO 10.91 cSt 5W30 formuation several times where the 100 C HTHS value is 6.9 cP!! That's the temporary shear down and with and SSI or shear stability index of 9.4 cSt. Note the intentional deception in using mixed units?    After a short while that 9.4 cSt oil has a viscosity corrected dynamic value of 7.8 cP. But as the SSI is still within the range of an SAE *W30 whose lower value is 9.3 cSt.    This allows them to continue to call this SAE 16 weight oil a 30 weight, the cake, and still meet the API requirements for fuel efficiency IMPROVEMENT mandated by the EPA. The eating of the cake. By the time you've worn out your motor doing the responsible thing by adhering to the warranty requirements, (the stick), you get deprived of the carrot, wear control. So sad, to bad.   So what can be done? Do I need actually say? [Anton Parr]       Even this must be monitored if the oil is on the low side and the VII an organic or you opt for a 0W40 with an even lighter base oil and more / higher MW VII. (Note the lower density of the 40 weight versus the SAE 30 mono-weight?)    There is another workaround. Temperature. An SAE *W30 run at a bulk temperature of between 180 and 195 F.    Being the belt and suspenders sort I am I do both. Run it cook and run it heavy.    In Part II I'll work the AW package.
