Just picked mine up after the first service.  I told them I wanted to wait and do the recalls later.  They said to bring it back whenever I was ready.  I did not have to sign anything.

Dont do the recalls! Tell them you want to wait until they sort out the issues with those updates.

Taking advice not to get the recalls, been waiting for a few weeks for them to get sorted out and they still can't get them right.  I've had such bad luck with this truck that I wouldn't be all that m

Folks-  Just some words of advice for those of you who are going thru this but have not yet visited your dealership.  9 times out of 10 your dealership is not going to have any clue about this issue a

Ok just dropped it at the dealer. We’ll see what they say. My CEL was still on so that was good for them to pull codes. I had to raise a little hell to get them to give me a loaner later today if I need it. Haven’t had the mushy brakes since but I’m avoiding using the app until this gets resolved. The shuttle guy mentioned that a lot of folks have had this issue in the past week. Fingers crossed GM gets a fix for it soon!

 

OK they called from the dealer.  Just like they've been telling all you guys it's a software issue related to using the OnStar App.  GM is working on it and they are currently re-calibrating my truck and clearing the codes.  If it holds for 30 mins without throwing any new codes they will release the truck to me, otherwise they'll give me a loaner.  Heading there in a few mins, hopefully I can take her home.  He said not to use the app at all until they are notified by GM that the issue has been resolved.

So if we have the recall done, and don’t use the app to start it, it should be fine?

That’s what they’re telling me. And, When GM has an official recall or service bulletin to address this issue, I’ll have to bring the truck back in to have the module updated.

Mine was “fixed” 2 weeks ago.  All has been perfect since then, complete with remote start via the app, and tonight it came back.  
 

restarted the truck 4 times and good except for CEL. 
 

anyone know if there is an issue with driving with the CEL on until a fix is there?

Just got a call from dealer that my truck is FUBAR until the next software is released.  They will not give me the truck back because my ABS is currently comprised.  I am in a loaner for 2-more weeks.   I would advise anyone with appointments to get anything software related done, to wait.

I emailed my service advisor last night and she emailed me this morning telling me to bring it in. Here is my question, I now know the trick to limp along with the CEL on.  If that is working out and I have my brakes back, should I just wait out a software update or bring it in?  
 

Best case scenario I bring it in and they claim to fix it only for the issue to recreate in a week or so.  it’s abundantly clear that Chevy has no idea how to fix the software and until they do everything else is a bandaid.

I’m just driving mine with the CEL on cause I love my truck aside from this issue. Also my dealer now seems to be ignoring my calls. Had a loaner 2018 over the holidays and didn’t like it.

The CEL informs you one of the Modules are in error. Some errors will prevent operation of the vehicle or the user will notice a change in driveability. Just find out what the CEL is telling you just in case continued operation will harm you or the vehicle. Stop at Auto Zone etc, and let them tell you what the codes are.

Just called On Star. They have no knowledge as of this time of the issue. Asked me if I wanted to go ahead and try using the app again...Politely declined because I didn't want to go get CEL cleared from the dealer again. They had no idea what the problem was or when it's going to be fixed. I'll wait a few weeks and if its not fixed I'll cancel On Star and try again after its fixed. Hopefully that is the issue and it doesn't happen if I remote start with my key fob.

I have (sitting at the dealership) a 2020 GMC AT4 just got on 11/20/19, had to take it in on 12/13/19 as i got the ESC error code and check engine light that wouldn't go off, dealer called a week later and stated that GM told them to replace the brake module, so they get the module but apparently need to order new bolts to put it in as they cannot use the old ones, so another 2 weeks later they contact me and say all parts are in but they cannot get the module to communicate correctly with my computer system and there was a software update just released that day (1/3/20) and they need my truck for 5 more days and i might get my truck back this week. I also asked if they would get the battery cable recall issue addressed and he said they should. So as of this Friday it will have been a month that i don't have my brand new at4, does this seem ridiculous to anybody else out there?? anybody experiencing a similar issue???

I have had the same issue on my brand new 2019 LTZ still driving the loaner truck after 3 weeks. Never had any problems till they did the brake software update and i only have 3100 miles on it. Mine did it twice after the update both times i started with my phone.

I just had this happen two nights ago and was able to get them to reset to just a CEL after a bit of messing around. Dealer pulled codes and opened a case now waiting for a new update to be issued from GM. I just had the brake recall done and module updated of course their is no ETA on the update...7,200 miles

Add me to the list. After the Brake recall. Started the truck via fob and inside the truck itself, no problems. Then same day, remote start via the MyChevy app and Service Brake messages came up. My dealer asked me if I drained the battery somehow the night before that might have caused the errors. I didn’t.

Good to find this thread. Following.

It's not unheard of. 

When the dealer had my truck for three weeks, I had a loaner...so I didn't even bother to ask.

I think there are other's on this forum that have had either dealer / GM make their monthly payment.

      Stabilitrak conversion to Z71

      By teamjnz · Posted

      Sounds like converting will be a bigger endeavor than I was thinking. This truck doesn't have 2Hi like the Suburban did. The Tahoe has 4Hi and 4Lo and a button to turn of traction control.   From what I understand the Stabilitrak uses open diff in the front and rear. When wheel speed is not the same the stabilitrak uses the ABS system to slowdown the spinning wheel(s) to transfer power to the slower non-spinning wheel(s). I thought the transfer case was open too. Being able to transfer power either more to front or rear depending on wheel spin. Maybe I miss understood some information with you saying and power transfer is 50-50. Thanks

      OCI, not when but why?

      My brother has a 2007 Avalanche with afm 5.3. It`s got 176,000 miles. Runs like a clock. Never been apart. Co worker has a 2010 Tahoe with afm 5.3. 230,000 miles. Never been apart. Runs like a clock. So, even though cyl deac is a weak spot, they can go the distance.   BUT, these engines had the oil changed regularly, AND had 5w30 as spec. I wonder if they would have lasted this far on 0w20? I`ll bet not.

      I certainly could be wrong but I hear of pickups far newer than that 2007 cutoff which may not be going to the wrecker but are having engine work done and be that a reman engine or new engine or trying to repair the existing engine. Some of it would be design issues as per the cylinder deactivation system that GM has and one of those lifters wiping out the cam and the question of oil changes moving the needle or not on that whole mess, or in the case of Ford pickup engines that have the long timing chains and wearing them out and the roller followers and phasers and some of that certainly goes back to oil change intervals. But in those various cases the truck has all sorts of life left in it and so the unfortunate owner and may be original owner or used market owner that is pouring money into repairs so the truck is not seeing the salvage yard yet but damage is happening by infrequent oil changes. A friends son had bought a 2018 I think it is half ton GM and it had some sort of extended or used dealer warranty on it and of course the lifter issue bites and its rattling and so the dealer had to swallow the bill and was at least 7000.00 and I think they only replaced what they felt they had to replace so yeah, I can see that being a ticking time bomb in the not too distant future. Would frequent oil changes cure all these engineering "marvels", probably not but some engine designs have shown that they do much better if the oil is changed a lot more often then if the manufacturer service claims are followed. New trucks cost so much that there is an incentive to keep the existing truck on the road by repairing.

      get a good code reader, and find out what problems the truck has noticed by reading codes. cheap ones can only get basic engine codes, you may want to get one that can get codes from all the computers in your truck.

      This is sort of my point, salvage yards aren't overflowing with all these 'poorly' maintained trucks - excellent/good/servicable condition otherwise, salvaged only as a result of a bad engine from poor oil change regiment.    In my area, there are no 2007 to newer gm trucks/suvs in any salvage yards. A few are in the 'recyclers' with very obvious reasons for being there - wrecked.
