Whelp, the truck relapsed last night.  I have been using the app to remote start the truck since I got it back over a week ago and no issues.  Last night used the app and when we got in the truck I noticed the CEL was luminated prior to pushing the start button.  Once the truck was turned on, all the warning messages began popping up.  Restarted twice and the brakes reset and was able to drive home.   Will be contacting the dealer on Monday.  

Same exact thing happened to me with the same behavior.  I was all good for about 10 days using the app etc. and then it went to CEL.  
 

I was waiting for them to have another Silverado in stock for me to use as a loaner so going to pick up tomorrow.  I wasn’t about to take another Trax or Equinox.

My brakes were effected. All the same codes. The latest version of code... onstar says is there is an issue with my ABS brake system. CEL. The new symptom is while park assist is turned on. All the sensors light up like a christmas tree.

Yep. I had the original codes first with recall. Lost the brakes not completely but I had to push hard to stop. Then after the last update I got this happened. Goes back to the shop tomorrow.

Question for those of you who are on your second or more return to dealer to fix...  I know in some cases, the dealer is just keeping your truck while they wait for a fix.  Others are claiming they have it fixed and giving it back for the same issues to pop up.

 

What is your plan for the long term?  I ask because im taking mine in tomorrow for the 2nd time.  I know that they are going to clear the CEL and say they did this that or the other to fix it, claim its good to go, and its not going to work.  Do I just keep playing the back and forth game with the dealership and hope for the best?

There are trucks that have not experienced any type of brake loss indication [ie brake loss, idiot lites] before or after the recalls and using the Remote App Start. [Mine is one of them so far]

There are trucks that experienced brake loss indication before any recalls and had the master cylinder, brake booster and brake control module replaced. Most of those vehicles were fix while a few were not.

There are trucks that went in for the recalls and experienced brake loss indication with the use of the Remote Start App. Some had parts replaced while others were left at the dealer and others were told not to use the App.

The vehicle is kept by the dealer and they give you a 2019/2020 truck as a loaner...........

Lots of variations exist for sure. The loss of brakes is enormous and the predictability of the loss makes a reason for standing down from the vehicle while GM comes up with a solution. GM should be reaching out to those affected with some type of compensation. I believe this issue is bigger than we realize and GM is aware of it. Just luck has prevented an accident or has it?

I'm picking mine back up from the dealer today, I had just brought it back to the dealer this morning for the second time since the recalls. From the post above I'm in the third camp, both times my lights have shown up it was after starting the truck from the app. After restarting the truck 3 times all the lights go away (including the CEL).

 

Mine seems to act normal after the restarts and I have not tried to drive it with the engine lights on.

 

Also this morning the a audible message came on in the truck from On-star stating something along the lines of not all onstar features available. Are they finally realizing that the remote start app has a problem?

Would anyone be interested in talking to a class action attorney? If we've got about 100 (eyeballing that excel sheet) owners impacted here alone there has to be thousands nationwide.

I would this is BS. I can’t tow my tractor or anything because of being worried about this crap.

count me in on the class action law suit. I should say if you're one of us having the brake failures, DON'T USE THE GM APP TO START YOUR TRUCK.

use the key FOB or just go start it yourself. I was told by my dealership that the app is messing things up.

I got my truck back Thursday afternoon. Friday morning - a new problem arose. “Learning remote - please wait”.  After I had started it at the dealer (with remote) and driven home - and started it (without remote) on way to get gas. Started it once more after getting gas on way to work. Ready to leave work - won’t start with button on dash. Will with remote - but truck won’t recognize remote to let truck “energize” or whatever. 
 

Sent text to service advisor and salesman to get a wrecker, bring me a loaner and come get this POS.  They did. Friday afternoon I traded that lemon back to them. 
 

Guess I should change my screen name to 2020ArkansasSierra now.

Same thing happened to me after the recall was done,and I started the truck with the app.

there is a bulletin issued on January 6th and GM confirmed to my dealer that it is in fact a bug with the app that the brake issue is cause by starting the truck with the app.

On my service ticket it says not to use the app.

Hope this help.

    • That makes sense, and I think you are describing the real product problem. Capturing data is the easy part. If the owner or technician has to manually dig through five minutes of millisecond-level logs, the product has already failed. The device would be at the ECM harness, not at the OBD port, so I agree that data retrieval and event marking need to be thought through carefully. The way I am thinking about the architecture is: The recorder itself should not depend on a phone, app, Bluetooth, Wi-Fi, or cloud connection to capture the event. It should always keep a local rolling buffer and lock the event locally. A button, phone app, or small cabin device would only act as an event marker. If the driver feels a stumble and presses the button 10–30 seconds later, the pre-buffer has to already contain the useful data. For data retrieval, the practical options would be a sealed service USB lead, Wi-Fi download, or a phone/cabin companion device. I would not expect the owner to remove the ECM-side module or work with raw files directly. The cloud or AI side would be for interpretation, not for capturing the event. The truck may have no connection when the issue happens, so the evidence has to be saved locally first. After that, cloud processing could help decode the data, compare it against baselines, and generate a readable report. For the first version, I would keep the automatic triggers conservative and objective: driver event marker bus-off error passive voltage drop / brownout device reset FIFO or queue overflow a normally periodic message disappearing side-to-side communication mismatch, if the topology supports that For “learning normal,” I agree with your point, but I would not want to overclaim it as automatic root-cause diagnosis at first. A realistic first step would be learned baseline comparison for that specific vehicle and operating condition. For example, a value would only be compared against similar conditions: RPM range load / MAP throttle position gear / vehicle speed coolant and oil temperature battery voltage AFM/DFM state, if decoded and validated Then the report could flag things like: this periodic message disappeared compared with its normal timing this value deviated from this vehicle’s normal range under similar conditions the same abnormal pattern repeated after the same type of event the anomaly occurred together with voltage, oil-pressure, misfire, or communication changes But I would still call that “abnormal pattern detected,” not “replace this part,” unless there is enough validated repair data behind it. So the intended product would not be “here is a huge log.” It would need to be an event package: what triggered the capture how much pre/post data was preserved what changed before and after the event whether the device itself reset, overflowed, or saw a bus error selected graphs around the event raw data only as supporting evidence From your perspective, what would make this kind of report useful instead of just another datalog? For example: What are the top 5 parameters or events you would want highlighted first? Would you trust a learned baseline for that specific vehicle, or would you prefer fixed thresholds? How much false-positive flagging would be acceptable before you stopped looking at the reports? What would a one-page report need to show for an independent shop to take it seriously? For misfire, AFM/DFM, oil pressure, or U-code complaints, what would you want the tool to flag automatically?
