GM is “aware of the problem“, as we enter the second model year of the same vehicle still having the same problem. Come on GM, get your shit together.
 

Unbelievable that the same crap that happened to me in January is still happening to others in December. I mean, it’s only brakes I guess...

You've documented on a public forum that your truck has brake issues and continue to drive it hoping maybe it won't happen again.   If it were my truck it would be at the dealer to be fixed

There is no reason why today’s electronics heavy vehicles can’t record every instance an indicator lights up on the instrument cluster signaling a malfunction/fault.

 

GM simply chooses to not incorporate this logic into their software.  It’s more economical for GM to simply tell you, “sorry, unable to duplicate”

100% accurate.    My AT4 was towed into dealer twice in 2 days.   This is exactly what I said to my service rep.   He said “what are you complaining to me for I don’t engineer the vehicle.    Call GM to complain”    I have bought 6 GM vehicles in 12 years ( for my company and family) !!!  This may be my last which really sucks as I love my AT4. 
 

After the 1st no brake visit,  they gave it back saying they could see the check engine light but the codes were gone after the third restart.  And they couldn’t duplicate it.    But the service rep,  service manager (AHole) and VP of the dealership all told me my car was 100% safe to drive with my kids in the car.    12 miles later ( 1 hour later). I had little to no brakes again with all the same warnings.    
 

I told them I am not accepting the car back if they tell me that they couldn’t duplicate it .   Just tell me who their council is for my attorney to send the notices.    I will go buy a ford/dodge I guess which will really bum me out.  What else can you do.  I can’t take the risk with my family or me hitting anyone else’s.

Wonder what the percentage of vehicles has to experience this be before GM will acknowledge and address it? 
 

I’ve been curious what the percentage of trucks with this happening actually is. I have a feeling it’s either really a lot of them due to a design flaw, or a very small amount whose owners all end up here to talk about it.

IMO, if there are a lot of them, it’s a design flaw. 
 

If it’s very small percentage, there has to be a commonality, like build date, location, parts supplier etc (who knows, I am just throwing things out there). 
 

this terrifies me. I love my AT4, absolutely love it. But I love my brakes even more! ?

2019 Silverado High Country owned 1 month with 1500 miles

 

12/23/19 brakes system failure while backing out of a parking space.  Truck was in limp mode with very little, 5-10% braking on first attempt to brake and approximately 50% on second depression of the brake pedal.  Limped to dealership which was 2 miles away and was told something in the brake system requested the check engine light.  Manager states he reset the computer and a visual inspection showed no leaks.  Told everything should be fine and to bring it back on 12/26/19 and they will take a closer look.  I live 40 miles by freeway away, this was not a safe option!  After multiple discussion between the sales and service departments I was put in a rental (dealership expense) until they can look at truck.

 

Unbelievable GM knows of this problem and is rolling the dice instead of a hard and safe fix!   Truck was sold without having recalls performed.  Took truck in for a flat tire at 700 miles and dealership completed recalls.  While doing so, it disabled my camera which disabled all driver assist (lane departure, following distance, auto high beams, etc.) and had to be brought back.  Dealership messed with it for 3 hours before deciding to order a new camera.  Left the dealership and all systems began rebooting themselves and coming back online.  Took truck through brushless car wash and discovered my truck is one of the lucky rear window leaking trucks!  Still waiting on this to be corrected.  On this note, while I was at the dealership for the brake failure last night I poked my head in a brand new 2019 GMC Denali in the showroom and the headliner had a huge stain on the passenger side and the rear window leaked on both sides.  Just 5 minutes before this observation a service tech told me the windows only leak because we owners take our vehicles through automatic car washes which we are told in the owners manual not to.  And to top it all off, yesterday morning I was advised by the OnStar rep there is a new recall (12/18/19) for an oil line coming disconnected.  Way to go GM!

Mine did this a couple of nights ago. Had very little for brakes till I got home, about 4 miles. Next morning everything seemed fine except check engine light was on. That evening when I got off work the check engine light was no longer on. Was also  showing service trailer brake system and service ESC. Going to dealer tomorrow afternoon.

There's no fix yet as far I I'm aware please follow the 2 new recalls thread. Mine started doing this after having the recall done and has been at dealer a week, service bulletin from 12/20 says to clear codes but if it happened again they don't currently have a fix

Lost the brakes today!!! Was stopping from about 45 mph and thank goodness no one was in front of me. I called roadside assistance and they took it to the dealership. I got a call today and said the battery was low and they charged it up so get it which I refused and said a truck with 6000 miles on it should not be discharging. 
I ask if they put a new battery in and said no GM said to just charge the battery??

i told them to find what was discharging the battery and they said they would try. 
all of this happened one day after they had completed the recalls. 
called Chevrolet and spoke to an advisor who is supposed to be on the case. Lol

what if this happens while towing??

there has to be something that can be done instead of here is your truck back and it should not happen again?

what if someone gets hurt really bad from another malfunction??

im really scared to drive this thing now and don’t trust it especially when towing!!

First time they replaced the master cylinder, second time they reprogrammed the brake module, the third time I just let it reset and went on my merry way. Hopefully my new truck will be here shortly after first of year, supposed to be in Kansas City on the 29th. Dealer can then worry about it, also the brakes squalling like a wounded elephant and the two open recalls still on it. Plus the infotainment screen.

That’s not what I wanted to hear.  Towed in twice already for no brakes.   Just picked it up and GM had them replace the battery (said there was an issue) and also the master cyl and related parts.    I was hoping it would work.   I am really nervous to drive with my kids in the car.  I need to take it on a 600 mile trip in 2 days

With the potential of losing brakes while driving, is there any sort of emergency braking option?  All I see/have is the parking break button. Would that act as an emergency brake if you press and hold that in these situations where braking is only a small percentage of normal?

I don't believe that the park brake will engage with vehicle in gear.

You still have the mechanical push through on the brakes. Not power assisted obviously at that point but it’s still there.

      That sir is a choice. And even if it were not for all the reasons stated, this disruption has zero to do with the reality of the actual logistics and everything to do with the greed of SPECULATION. Spot price is irrelevant to reality.

      What I think you're saying is there is supply here at home, and in Venezuela, and we could ease pricing if only it were favorable to do so.   Well, yes?   But that's not the current market. Supply isn't what could someday exist, if only, it's what producers are willing to produce and sell at a certain price point.   The national price of single family homes would come way down if we'd just slap together a few million homes this summer.   RAM and GPUs would get a lot cheaper if we just set up some factories to produce a bunch more and stopped using it to build out AI data centers.

      The turn signal/multifunction switch is faulty.  I've seen a few of these go bad at work.

      If we actually used any significant amount of that source in the USA then I'd agree but we don't. We've had that discussion before. We drill and pump more than we use. Thing is, we sell. We export. Gas and Crude. It's more profitable so any shortage here is self inflicted and LEGAL.    I worked a gas plant that has multiple fuel sources available and I worked in the furnace and boiler plant in that facility. I'd had days we swapped fuel types four times in a twelve hour shift which isn't done on supply but on margin. Two of the fuel sources are internally generated. Tail gas and DAK, both of which are sold as well a consumed. We always had more than we needed to run the process but we chose the fuel that produced the best margin not bought at the cheapest price always. A good bit of math to that and back in the time that was done on a slide rule.     I worked the Shale Oil Semiworks of Chevron Research and CONOCO Research in Salt Lake City. That process never went into production although it was very successful. Why? Did we lack oil bearing shale? Nope. Price of crude never made the margins work. That was in the late 70's early 80's. Remember history? What was happening then was a reaction to that situation. It didn't drive it. If so then it's easy. This isn't a supply and demand thing. This is a profit and margin thing and AI rules that now.    In no refining situation that I was ever in would a bomb hitting a well anywhere in the world 'instantly' interrupt or even distress the supply. Most plants have more than a months worth of crude in the tank field and more in pumping stations. That yo-yo could play out over days, weeks and maybe months and have zero impact on plant operations. How many times has this been off and on in the last few months? These people and not stupid. These plants measure down time in hundreds of thousands of dollars per day. They are not sucking fumes or waiting on the next truckload with baited breath. Besides, as I noted, they are for the most part 'vertically integrated'. They own it from the dirt is sits in to the delivery rack and sometimes to the pump. It has a HUGE shock absorber built in. When production suffers, refining wins and when refining is winning exploration is killing. The rest of that crap in the news is a 'news cycle'. Government dipping in to reserves? Oil is stealing their milk money. There's a reason Chevron abandon Venezuela infrastructure and it had nothing to do with security of US citizens. Nationals run those plants. it has to do with MARGINS disappearing to corruption. They are in no hurry to return. Is there supply there? Oh yea. More than enough to offset what is bought in the middle east. Just isn't ???? Profitable.    We have supply. There are places in Illinois you can drive a pipe into the ground and run your homes natural gas furnace on it.    A refinery fire will gum up the supply works but not a localized war where the market is using a limited supply from. Now Europe, that's something other....
