This just started in my 2020 Ascent, when I put the car in park the parking brake activates. In another thread in years past this has been a problem, do they have a fix?
Does the parking brake activate each time as soon as you shift to park, or does it activate after switching the vehicle off?
If the latter:
“When the electronic parking brake has not been used for a long period of time, the electronic parking brake may operate automatically after the ignition switch is turned to the “LOCK”/“OFF” position. This occurs due to checking the proper operation of the electronic parking brake and does not indicate a malfunction.”
Does the brake indicator on your dash blink? It blinks when there’s a malfunction detected. So if it’s not blinking the system should be operating normally.
