What is this nonsense?

Glava2876 · January 30, 2019

Anyone ever get this message -no detail just telling you to make an appointment for a "diagnostic alert" that needs "immediate" attention.

I'm thinking that they just want to tell me I don't have Onstar anymore and to please sign up fast to keep paying them.

Since it’s the red ! stop sign and your truck is a 015 that is what I would assume “free” five years is up. I bought mine new off the lot in 015 and nobody ever got my email right to even send me one report yet, but I’ll bet they figure it out when it’s time to “renew” it...

There has been several reports on this site of antenna failures with the OnStar/XM antennas sometimes takes out one or the other or both. And sometimes the caused by water leaking into the cab. So check to see if XM is still functional if you don’t have a current plan should still get the “preview” channel(s) Usually if something like this is the problem the green light on the mirror will go red.

Being it is a 015 there has been a couple recalls so I’d double check your current on all of them if you don’t know for sure. Simple call to the Stealership or email your vin to [email protected] and ask for a copy of the service records (can also ask for a list of the RPO codes if you don’t have one or your window sticker)

The monthly diagnostic report will also fail if you have something constantly plugged into the OB2 port under the steering wheel ie Range device, spitter for Amp steps ect.

Don’t have a clue, probably a blessing but I’ve never gotten squat from OnStar after I bought the truck, I hit the button to tell them to turn off the demo mode on the Infotainment system...never heard another word out of them. Yes they did turn the demo off ?

makes me wish that I should of just bought the work truck version

I hate being tracked by onstar, I hate the big screen tv in the dash, I hate the rear view mirror blocking my view, i hated the exhaust tip, i hated the giant 20" rims. lol

Thanks, that what I figured. I have received recall messages in the past and am current on all recalls. I know my bumper to bumper is up, but my in service date is September 2015, so the 5year 100k driveline is still good. And luckily, since the triple A8 flush early on, at 40k miles it still works great.

There is an article around here somewhere that shows how to disconnect OnStar if you are concerned. It looked pretty simple.

did you even test drive the truck? Lol

BTW if you have a cell phone, You are constantly being tracked

Sierra Dan · January 30, 2019

They probably just want you to sign up for Onstar

I hate being tracked by onstar,

Even my 2014 WT has OnStar built in it. Your cellphone listens and tracks you at all times, even when it is shut off or out of the service area. My buddy and I were talking about his septic holding tank system on his RV while out moose hunting, not in the service area. When I got home YouTube tried to show me a bunch of videos on RV holding tank systems, even though I have never searched such a thing. They have good algorithms, but not that good.

OP, OnStar has no precedence over any systems on the truck, if OnStar is not activated, it can't negatively impact anything on the truck. If you are the tinfoil-hat type, just pull the OnStar fuse out of your fuse panel and breathe easy.

Darmichar · January 30, 2019

OnStar is the only thing I have absolutely despised about my 2014 and 2018 Silverado. Why GM continues to shove this horribly overpriced service down their customer's throats is beyond me.

sk · January 30, 2019

The red "stop sign" means something is wrong with your OnStar equipment. Of course if you don't plan on ever using it you probably don't need to have it looked at.

If you just let your OnStar subscription expire but your equipment still works correctly you will get the yellow caution triangle in those diagnostic emails.

Yes, get them every once in a while, then when you go to the website or scroll down the page, there are no problems. No idea what would happen to set off this alert.

Thanks!

If that's the case, it would be nice if they told me that on the Onstar diagnostics, instead of telling me lower on the screen to call and make a service appointment.

But since I received this message, which has the current mileage of my truck, isn't Onstar working?

I have to admit that I really don't like Onstar, especially the cost. I have it on 3 newer GM vehicles and only pay for more on my wife's.

Nitrousbird · January 30, 2019

OnStar is such a rip off. I didn't even bother with doing the work for the extra free 2 months. I'm not paying $15 to enable remote start via the app. Nothing else of their service is worth anything to me.

Hell, I "might" pay a $1 month for the crash assistance service. And that is a big maybe.

Overpriced service that way under delivers.

Might have been as simple as the signal was block when tried to run the test multiple times. The guys running the Range devices were/are having this happen. Some of them that care have figured out what day their trucks get tested and remove them that day. Could have been that day you parked in that underground garage that use to be nuke missile silo and OnStars weak little China made satellite couldn’t penetrate it? The LED on the mirror is supposed to glow green if it’s not working the LED glows red. Foilheads can verify this for you. So maybe it didn’t work a couple of key cycles for some reason and now it is again. GM just wants to verify that heaven forbid you wreck your ride that they can call you via satellite and ask if your ok using your name since they see the death bag exploded as your trying to explain to 911 where the h#ll to send the Bambalance...

If you would like to test it out yourself here is the at home instructions

1 start truck leave truck running

2 take note of green led if it’s red your dead well to GM anyway

3 push talkie button on mirror for OnStar

4 wait for someone to answer using your name is some sort of broken word & tounge

5 acknowledge they are acknowledging you (no real they have switched vins and accounts b4)

6 repeat the following “this is only a test of my GMCs onboard OnStar capability if this had been a actual emergency you would have heard the rest of the people in the truck screaming and crying for help”

7 ask them why the fu@k GM finds it necessary for the OnStar lady to say “this vehicle is connected to limited OnStar services” and scarce the sh!t of people usually when they are trying to back down the drive in the dark on their way to work at stUPid hours of the day or night.

8 report back to this thread on your findings of #7...
