Brake Pad Life

So I currently have about 1300 miles on my AT4 3 weeks into ownership and somehow, based on the brake pad sensors in the truck, I have gone through 20% of the pads life (I have not checked this by other methods yet) . I don't brake hard, haven't towed yet and haven't been in stop and go traffic at all. Is anyone else running into this? Not sure if anyone else is experiencing this or if they are hitting a point where the pads are not losing mass so quickly due grooving with the rotors.

this is under investigation by gm engineers they believe its a software anomaly but have not released a fix for this yet. i just had this on a 2019 with like 1500 miles the brake life was saying it was at 30%. nothing is out yet as far as an update for the software.

This isn't true. Have you read the last few pages at all?

i dunno if you have ran into it yet, but i have already replaced two whole brake booster modules on the 19s, just had one this past week for "service brake system" warning /SES light. SI leads you to perform a brake pedal travel relearn and clear dtcs and they reset replace the brake booster module. its 1 piece, ebcm, vacuum pump, booster all in 1. they are on spac.

I have 5200 miles on my 2019 1500 RST and its shows front break at 64% back at 73%.  Mostly highway miles as well, no hard breaking, no stop and go traffic.  There's no way the breaks are that garbage.  I'll be replacing front after 12k miles... no way.

GM has a new fix for this. Go to your dealer and it’s a 15 minute software update. I have over 1000 miles on mine since the patch was installed and my front and rear’s are showing 99%.

Yes you also get new brake pads if truck has over 6000 miles.

Thank you, it says that was released August 7, 2019.  I was just in my dealer Friday picking up some parts and they told me nothing available yet.  I will be going back soon to see what else they missed.

I had it applied in mid-August and it's been working great so far.  Sometimes you have to hand the dealer the TSB if you have it as most of them aren't really great at looking things up.  It's just easier for them to say nothing is available when they search once and find nothing.

Wondering same thing. My 2019 RST Crew has 3790 miles and 63% front/77% rear brake life left. I was planning on inquiring at my first oil change but figured there is no way this is accurate. You'd have to be replacing pads nearly as often as you rotate tires.

Bulletin 19-NA-191 applies only to Cadillac CT6. The Bulletin was updated 9/16/2019 to exclude the Silverado and Sierra. The Brake pads are not replaced, just the software update is done.

So I got the software fix apllied yesterday along with rear window seal fix due to leak. They did not reset the brake pad life I only have 5000kms so they should have according to the tsb. Does anyone know how to reset it? I follow the manual, scroll to the brake life, press thumbwheel, attempt to select front or rear but cannot as they are greyed out. Only available option is it disable. I tried that, juat comea back to old life. Tried in access mode but that page is only available if engine is running. It is hard to see in the pic but they are greyed out.

Dealer has to reset it.
