I used the parking brake on a boat ramp, then after I released it the light stayed on. Then after I was driving up the ramp my information panel started beeping and displaying "Stabiltrak off" "Traction Control Off" and "Service Braking System". After I turned it off, all that went away, but then came back a day later for a few minutes. Then went away again, then today it all came back again while driving to the store. Any ideas on this issue? I reapplied the brake and released it hard thinking maybe it was stuck... but it wasn't.

 

Check the switch that the parking brake operates. It may be sticking.

 

There nay be something else with the brake system not working correctly. It's just coincidence it happened after using the parking brake. Pull the service codes and check it out.
