I changed the brake pads which were pretty easy to do as they are the same for the front and rear and there's only 2 wear sensors one on the left driver side front and one one the driver side rear on my 2020 gmc 2500hd denali duramax after I drove it on ramps to do the oil cooler Relocation kit so I'm able to install the bigger oil filter instead of that small one that it comes with a service parking brake message illuminated with parking flashing and the wrench every now and again it will go off I hit the parking brake before while it was off and thr brake engaged then the message popped back up and I couldn't move I had to disconnect both battery terminals waited for a minute reconnected then I was able to disengage the parking brake then the message came on then went it and came on again smh does anyone have any idea what's going on???

I’m having the same issues, I have a 2020 Chevy 2500HD Duramax, and my service park brake light won’t go off, I’ve tried disconnecting the battery which it went off for a minute then came back on after I tried to release the park brake with the button, I also looked at my brakes and they still seem about 70-80% good, I’ve also tried cleaning the connectors to the park brake actuators and that didn’t help, anyone know or have a way to fix this issue or any other ideas I could look at??
Thanks

We have a 2020 GMC Denali Duramax as well, 3500HD and our parking brake locked while I was backing up. I got it loose by just driving it but only went a short distance as I was close to our local garage. The guy took it in and looked at. The parking brake pad completely came apart in his hands. He removed what he could and then a month later I had the other side do the same thing. Same thing.. same guy and he removed the remnants of my park brake. Told GM about it and not covered under warranty. Truck was barely 3 yrs old and below 100,000kms. I see now there is a recall for the rear park brakes locking up due to "software". Truck needs to go in and have this remedied but in my mind a park brake should not fall apart. Faulty parts perhaps as it was made during covid?
