Cable probably rubbed thru a wire by the floorboard. If you cannot find it soon, buy you a resetable fuse of the correct size and put it in.

 

There is a body harness that should be near the e-brake pedal, now it shouldn't be chaffing the harness and should have good clearance but I guess anything is possible, stick your head under there and peel back the carpet and take a look if something is chaffing the e-brake pedal assembly.

 

FYI, my 2019 Colorado had a "service stabilitrak" error the first month I had it. Dealer discovered that the factory had routed a wire harness differently and it was in contact with the parking brake mechanism somehow. The problem made itself known so quickly because my truck was a manual and the parking brake is used way more often than in an auto.

Definitely check to see if the parking brake has cut into a harness and is causing it to short.

 

For the sake of correctness, it is a PARKING brake, not an emergency brake. It will not help you in an emergency. Otherwise, I agree with previous posts.

 

Theres been roll overs from children pulling the brakes…. And a few other curious individuals.

Obviously ours are not the handle style. But yeah.

Newer cuvs are all electric buttons now. I’ve never tried it. Nor will I. But I would imagine they block the brake from applying at speeds.

 

We have a parking brake? Only time I ever used one is sometimes in standard shift cars. Even then usually just left them in first gear. I've had my 2019 Colorado since new 2 1/2 years now and haven't even tried it to see if it works.
