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.

      Is it time to put a piece of tape over the CEL?

      2015 Silverado 3500 right rear turn indicator failure

      consider doing electrical testing?  I would guess some power or ground wire/connection has a problem.   alldata.com has wiring diagrams, connector pinouts and diagnostic procedures you can use to find where the problem is.

      My First Project and GMC has me stumped

      By davester · Posted

      can you tell if the reader is actually trying to get codes, and the pcm is reporting none, or is your reader just silently failing because it's not communicating with the pcm?

      Any joy with this truck seems to be short-lived.   The CEL for P0172 ("bank 1" too rich) is now "intermittent".   I'm not sure where to check, or re-check, and my energy to keep chasing problems with junk is wearing thin. The P0172 seems to set as I'm coming to a stop, completely off the throttle, when fully warm. At least, that's what it's done the 3? times it's set.   Everything appears normal on the scanner EXCEPT long term fuel trim. There's only one bank on this vehicle because it's an OBD 1.5 with only one upstream O2 sensor. At idle, it's around -16.4% and will dip to -18% occasionally at idle or off-throttle. LTFT approaches 0 when throttle is held at 2500rpm. Short term appears normal, much closer to zero all the time. The LTFT tells me the engine is running rich at idle but compensating at higher load. But, why?   The EVAP purge valve doesn't appear to be leaking/sucking fuel vapor continuously. Is it sticking just as I come to a stop and the engine is choking on fuel vapor and sets the P0172? But that doesn't explain the persistently negative LTFT. Disconnecting the purge valve doesn't seem to make any difference.   I suppose that leaves another dang issue with the fuel injector. A leaking fuel pressure regulator, a new leak in the spider, or a leaking fuel injector/poppet valve I didn't see, or a small crack in one of the spider legs.   The vacuum line leading to the fuel pressure regulator doesn't have raw fuel in it. It doesn't even smell like fuel when it's pulled off, not until you suck air through it, then you can tell it leads to a fuel component. I'd consider that normal? Nothing is signaling this is a FPR issue from the outside, at least.   The oil smells like fuel but it's not building volume. I've noticed most oil in most engines smells like fuel to some degree so it's hard to say if the smell is an issue or not. Or if the engine just still smells like fuel because the crankcase was full of it a few hundred miles ago. But it's been changed twice since that original issue of the leaking fuel line dumping fuel into the intake.   Patience is running very thin. Every win seems to be accompanied by two steps backwards, or another issue that leads to removing at least the top half of the intake manifold. Enough! LOL

      Tire pressure for 37s

      By Chuck FB · Posted

      First off you mentioned "Toyo Says" and then gave the pressures 45/50, was this some person at the tire shop that pulled those numbers out of his head ?   Now of course I can't know your exact axle weights front and rear, however I have much the same pickup as yourself other than not knowing your starting weight as per the pounds the truck rolled out of the factory at due to the options yours did or didn't come with or what you have added beyond the extra tire weight. The correct way to know 100% where a person is at is by weighing each axle with the typical weight the vehicle is driven with and that means taking into account passengers and making sure you figure in a full tank of fuel and a little grace for whatever you may put in the bed "groceries" !    I am looking at and not that it really matters as all the tire companies use the same charts anyway, but I am looking at the comprehensive Toyo tire chart in the section that your tire falls under and I know it sounds confusing but your tire is not an LT metric tire like your factory tire but instead because its a standard inch measured tire its under a different category called an LT floatation series tire. That makes a difference as LT metric tires they don't want to see run below 35 psi at highway speed where as with the LT floatation series it can be run down to 25 psi on the highway as long as the weight on the said size of tire is agreeable with or less than that minimum 25 psi. It blows many people away that how is this physically possible, an empty truck for one thing and larger tires with the same size wheel diameter have a lot more air volume so they can carry the same weight as the smaller tire with less air pressure.    So my truck, I have the stock 275/65R20 wheels and tires and I have a bit of weight in the box with a bak flip cover and a rubber bed mat and some tools and spare gas. The front of my gas truck weighs a bit more than some trucks of the similar spec due to double batteries and alternators. However with full fuel and just me in the truck I am weighted such that I can run 40 front and 35 rear and so that is what I have done since day one.    If I base your truck at or slightly below the weight of my truck, in theory with your tires going by the tire chart you might be right around a minimum of 30 pounds front and 25 pounds rear. Of course that would hit pretty much minimum cold inflation pressure one could run with that tire size and a near empty truck. If you have access to an accurate weigh scale to do individual front and rear axle weights I would suggest you do that and make sure your topped up with fuel and whatever else in the truck before you weigh it and then you will have a great starting point to work off of and figure out what your bare minimum pressures are you can safely run. If you do much in the way of hot weather high speed driving, bumping up a bit for a safety margin is never a bad idea but just depends on what type of driving you do. I will include the Toyo chart and the floatation series sizes start on page 31. Without a doubt at these pressures I am speculating at minimum wise for your truck, it would most certainly ride very different then it did when you were using 55 lb front and rear.     https://www.toyotires.com/media/pxcjubjs/application_of_load_inflation_tables_20200723.pdf
