I have a 2014 GMC Sierra 1500 and mine just started doing it - today it was cutting in and out - figured it may be the satellite ?

I am in Northern California - San Francisco Bay Area.

Any thoughts?

1 fast ss: How did you resolve your issue? I have the same problem with my 2014 Sierra. XM worked fine for 6 years. In the last few weeks, I have been getting "No XM Signal Reception may be blocked". However, the raadio does work occasionally for 3-5 minutes, so I wonder if it is just a loose antenna cable. The AM/FM radios work fine.

Since you both have 14 models with the "Shark Fin's" that were the leakers, and had a tendency to rust, wonder if they both are failing. The newer generation has a different seal and connections, that don't seem to leak or have problems.

Thanks, JimCost2014:

Not sure what radios the antenna in the shark fin serves, but my AM/FM radio is working just fine. Do you know if that means anything about the shark fin and the XM not working?

 

BTW, thanks to YouTube, I opened up the radio compartment and checked all cable connections. no problems there. While doing this, I discovered that the XM module in my 2014 Sierra is located behind the screen and above the AM/FM radio, NOT next to the glove compartment as claimed by several YT videos.

You are very welcome.

 

XM/Sirius and On Star, and I believe maybe for HD radio. The 1940's antennae on our fender is still for AM/FM radio.

I have this too.  I bought my 2014 Silverado from my dad who didn’t use it for much except an occasional trip on hobbies and to move his pontoon.  Only had 38000 miles on it when i bought it in June.  My Girlfriend gave me XM for Father’s Day of this year and it worked great till last week.  I did the whole thing with XM over the phone and nothing worked.  Still reads no reception, signal may be blocked.  Dad never had XM on it because he doesn’t believe in paying for that.  So the XM has hardly been used although I’m sure the XM module was on everytime he drove the truck.  So, i guess ill have to troubleshoot once it warms up and i can work outside without freezing my butt off.  Till then, its regular radio or my Echo Auto from Amazon which works very well.

My husband and I also have a 14 Silverado.  Have started having issues with the XM radio (first), then the compass "stuck" on NORTH, now the red light for the OnStar.  

According to OnStar, (last year) truck was in the water off the shore of Newark NJ.  Just last week, called OnStar again and was told we were in Palisades NY on I-90 (Nope - in RI at the time!)  

Took to the dealer (last fall), paid the $199 to have it "diagnosed".  They told us the antenna (shark fin) was no good.  OnStar ran a diagnostic  when we called  (last week) from the vehicle and said there was a "trouble code" and we should take it to the dealer.  

Have done a bunch of research since then and found there was a "recall" (technical service bulletin) issued for the shark fin antenna on the 2015-18s.  Unfortunately, it doesn't include the 2014s.  

It seems the "fix" is to replace a poorly designed antenna.  Fairly straight-forward (I won't call it "easy").  Remove the drivers side visor and grab handle, loosen the (left side of windshield) trim panel and headliner.  One bolt holds it in place.  Clean the area, apply a bead of caulking around the hole in the roof, and re-attach everything.  

The challenge seems to be getting the new antenna.

Hope this helps!

I had this problem today on my 2017 Silverado. Went thru the power cycle with XM cust. svc. to no avail. I waited approx. 30 minutes, then tried it again and it finally came on. you WILL have to send a refresh signal. You can call XM and have them do it or you can do it online. The procedure is listed in one of the previous posts, above. Good luck!

I had to have a refresh sent to activate my Gen V Linkswell after removing the stock radio.
It worked rather quickly.
I suppose when I put the stock radio back in, I'll have to do it again.
Fairly effortless but this step needs to be done on occasion.

Has this been resolved yet? If so, what was the issue and how was it resolved? I have a 2015 GMC Yukon Denali with the same issue and I cannot seem to find the resolution anywhere!

From the posts above, it seems a call or an online request to refresh your XM subscription on your radio is necessary.
My experience and it appears from the previous posts to be so, as well.

My XM radio quit with this same message. The XM tech support told me I had to replace my satellite/GPS antenna. Purchased from Amazon and watched a U tube video. About 2 hours later, I’m jamming to my XM again. My cost was less the $100

      Another 6.2L engine failure!

      By MASONV88888888 · Posted

      My 2025 Silverado 1500 had to receive a brand-new engine (long block) under warranty last month at only around 16,500 miles. Before the replacement, the truck repeatedly displayed "Engine Oil Level Low" warnings, even though the Oil Life Monitor still showed around 50% remaining after about 6,000 miles since my last oil change. After seeing the warning several times, I checked the dipstick with the engine cold, and the oil level was completely normal. The next day, the message escalated to "Add Engine Oil." At first, I assumed it was just a faulty oil level sensor, so I brought the truck to the dealership. After inspecting the engine, they found internal cylinder wall scoring and ultimately replaced the entire long block under warranty. Before this happened, I was planning to install a 4-inch lift and suspension upgrade on my truck. After needing a new engine at just 16,500 miles, I honestly don't see the point anymore. I also contacted GM to ask whether my vehicle qualified for a buyback, but I was informed that it does not at this time. Anyway, this experience has left me with serious concerns about the long-term reliability of this engine. I sincerely hope NHTSA expands the current investigation or recall to include 2025 model and performs a thorough inspection of affected vehicles. My biggest concern is that these engines may fail shortly after the powertrain warranty expires. If GM truly stands behind this engine, then at the very least, please consider extending the powertrain warranty to 10 years for affected owners. That would go a long way toward restoring customer confidence.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Without exception but then I'm the odd duck, right? I know what goes into that test, how it is calculated and thus how to beat it. But EPA values are often not beaten by the general public and the government has in past years adjusted the means and methods to come to those values to more closely approximate "Joe Average".    The only real trick to beating that EPA average is don't drive like "Joe Average".    It's the same method you used to profit from "Economic Migration" and in doing so beat the 'stats'. But you, like me, are not "Joe Average".     The thing you don't seem to grasp is this "Purchasing Power Index" isn't forward looking. It doesn't predict what it going to be but looks backward and states what it was. They are not telling us what the THINK, they are telling us what they MEASURED. Example:    Wife says "I'm going to lose 40 pounds by Christmas". May she does, maybe she doesn't but the doctors office who weighed her when she made that statement and again at Christmas only REPORTS what the RESULT was. You and I can banter about what was possible and what aunt Tilly did till the cows come home but the result is the result. Arguing otherwise is.....irrational. That's all I'm saying. This isn't about:      What you are calling a 'Statistic' is a RESULT not a CALCUATION and as a result the RULE. Like gravity as a rule, it can not be broken.

      Rattle in the rear!

      By MASONV88888888 · Posted

      Just wanted to say thank you for posting this. Years later, your thread is still helping Silverado owners.   I bought my 2025 Silverado 1500 in January 2025, and I've had what feels like the exact same rattle since day one. After reading your findings, I believe my truck has the same issue with the cable carrier contacting the rear sliding window. To be honest, I had pretty much given up on pursuing the issue. It wasn't until I recently drove another brand's pickup that I realized just how quiet their cabin was—and how noisy mine has been all along. On my truck, the rattle happens on almost any paved road, gets even worse on rougher pavement, and I can even hear it during braking and acceleration.   I actually referenced your thread when submitting my case to GM, hoping they'll recognize this as a recurring issue instead of treating it as an isolated incident. The reason I reached out to GM first is because my dealership told me they would need to keep the truck for at least two days just to diagnose the problem. I was concerned that even after two days, they still might not be able to identify the source of the rattle before giving the truck back to me. I had also asked a few dealerships about this issue during previous service visits, but none of them seemed to know what was causing it or had a solution. That's why I decided to contact GM directly first, hoping they might already have an official repair procedure or guidance for this issue.   I also hope GM eventually comes up with an official fix for this problem. I have a feeling there are many Silverado owners experiencing the same rattle, but most either choose to live with it or simply don't know what the cause is.   Really appreciate you taking the time to document your diagnosis. Your post is still making a difference years later.

      Do you have access to BP fuels? Some stations have Silver 91 E-0 priced the same as their 93 E-10.  There is a local Marathon with 90 alky free for $6 a gallon but I go down the road to BP for $5-ish. They also have a 100 E-0 but that stuff is $10 a pop.
