Remote Start Issues

I'm having a strange, random issue with my remote start and I'm curious if it's been happening to anyone else. Started when I tried to start the truck ('19 AT4 6.2L) with the onstar app. It failed, said not to try again and to start truck normally with start button. Did so, and the CEL was on. Got an email saying an engine/transmission issue was detected and to go to dealer within 7 days. Did so, they did a software download and all was good. 2 days later, same issue after trying to start with the app again. Except the CEL randomly cleared and I could use the app again after awhile. Over the last few days the CEL randomly comes on after a failed attempt to start with the app or key fob then will clear eventually. I uninstalled/reinstalled the app after speaking with onstar but that didn't seem to help anything. I have another appt at the dealer later today so I'll see what they say. I really like the remote start with the app so I hope this gets figured out quickly.

I think remote starting this way is a known issue.

What's the advantage over using the fob?

That's disappointing. I tried searching on here and google, but wasn't coming up with much. 

 

The biggest advantage to me is range. I work in a large plant and at shift change I can start it with the app from anywhere and by the time I get changed and out to the parking lot, truck is warm. The key fob doesn't compare.

I use mine all the time and have never had an issue. The advantage using the app over the fob is that you can remote start from anywhere, very handy if your not close enough to vehicle for fob to work.

I have a K2, but use the same app as you. I don't think the issue is with the app, but rather some electrical gremlin in the truck. You said it has also occurred when using the fob.

 

It could be something like low voltage reading that is preventing the truck from starting remotely. I can't remember exactly, but i think there are a list of requirements that must be met in order to remote start. your truck is triggering something, whether accurately or not, is throwing an error.

 

Are you certain the battery is in good condition? ground cables tight? a lot of weird things happen when the voltage is messed up.

You may be on to something. It does happen with the app or the fob. The issues started not long after I had 3 recalls done. One of the recalls was for a potentially loose ground cable I think. I'll mention that at the dealership this afternoon.

Looks like it was a bad knock sensor causing the CEL and preventing the remote start. Dealer replaced it and it has been working fine. Hopefully that is the end of it.

Seems like this one is resolved, but fwiw,

 

The vehicle cannot be remote started if:
. The RKE transmitter is inside the vehicle or if the key is in the ignition.
. The hood is not closed.
. There is an emission control system malfunction and the lamp is on.
. The ignition is in any mode other than off.
. The hazard warning flashers are on.
. Two remote starts or a remote start with an extension have been used.
. The vehicle is not in P (Park). 

 

If running under a remote start it will shut off if low oil pressure or high coolant temp occurs.

I have a question, you all say the “onstar app” I stopped using the onstar app a long time ago when the my chevy app was introduced, onstar told me the onstar app was discontinued, is the onstar app you refer to actually the my chevy app?

Or the GMC app.

 

All the same app, with different 'covers'

 

If you have a chev and a gmc they can both be operated with either cover on the app.

Thanks for mentioning that. I thinks there is a caddy, Buick etc. just a cover as stated

I thought so as it has been working fine for the last week but the exact same problem happened again this morning. Back to square one I guess.

      Trim level custom/pro

      By Another JR · Posted

      Are you going to take long trips in it?  If so, try out the seats in the various trims. For me the lower trim level seats were not comfortable.

      I have a 2016 that I bought new and still own. I'm around 129,000 miles now. The biggest problem was a transmission failure about 2 years ago around 95000 miles. No warning, just failed while driving down a back road. A reman GM transmission installed and it's been fine ever since. A few other minor problems along the way. I am in no hurry to replace it. It's been paid off long ago and do plan on driving this as long as I can.   I will admit I am leery about all the additional electronics in the newer models and feel that it is just more potential problems. I think there's actually more than I would have wanted in this 2016 but so far so good. I think even if something major like lifter failure happened, it would still be cheaper to at worst, drop a new engine in than buy a new vehicle.

      OCI, not when but why?

      I’ve own several successful businesses. I’ve bought homes and lived in different states. I’d witness several generations buy homes and survive in different economic circumstances. You get awful sippy when people have different experiences than you do. You live a life. I’ve lived a life. It seems our experience has been different. You can point out generalized statistics. Some people learn how to thrive when the odds are against them. Living in different states does make a difference in a persons quality of life and economic outcomes and opportunities. That’s a fact Jack. It’s my truth, my life. Hard work and long hours the right environment made my families life easier. And yes moving to a different state increased the odds of that happening. Stats are generalized. People who thrive don’t make excuses. They beat the odds. Others get mad and point to those statistics. I guess that’s you. My post pointed out how you helped people beat the odds. Somehow your panties got in a wad. Go figure.

      Good question, I don't remember for sure but I believe it was the HD. I will check and get back to you.

      Point of the post sir was that while both wages and cost are rising EVERYWHERE; the cost is rising faster EVERYWHERE than the ability to buy EVERYWHERE. We're not going down the location rabbit hole. I'm aware of what economic migration is. I've lived in four states including Texas.   It's what "Purchasing Power" means.   I'm not telling you what I think. I'm telling what the government, your government, data shows.   It wasn't an argument. It wasn't a suggestion. It was a statement of FACT. You are absolutely entitled to your own opinion. Your not entitled to your own facts. If you and I were, they wouldn't be facts.    fact /făkt/   noun Knowledge or information based on real occurrences. "an account based on fact; a blur of fact and fancy." Something demonstrated to exist or known to have existed. "Genetic engineering is now a fact. That Chaucer was a real person is an undisputed fact." A real occurrence; an event. "had to prove the facts of the case."
