Service Parking Brake message
So this is a new one...
We went to the lake to visit friends this weekend. Husband parked the Traverse in their driveway, on an incline, with the parking brake engaged. Almost two days later, I go out to move it so my son's girlfriend could leave for work. I pushed the parking brake button to disengage, and started backing up the hill. Ha! Couldn't figure out why I wasn't backing up very well until I realized that the parking brake was still engaged. I pushed on the brake pedal, and pushed down on the button again. It was then that I noticed the red PARK light on the DIC was flashing, not solid as it is when it is engaged. Also, the yellow park light next to it with the wrench was on, and suddenly the DIC flashed up a message to service the parking brake. Uh, what?
Here I am, stuck in the driveway, on a hill, with only a foot clearance on either side (rock walls), no way for the girlfriend to get her car out, 2 hours from the nearest dealership. Hmm. Pushing the button down, I could clearly hear the parking brake disengaging (and pulling it up I could hear it re-engage) but obviously when I pushed the button down, it was not actually releasing the rear wheel. We tried turning the car off and on, but that didn't help. I put it in drive and slowly moved the car about 10 feet down the hill and out of the way so she could get her car out. Not the best thing since the left rear wheel didn't turn, but we had no choice.
I did exit the car, which I now realize after Googling is probably what helped release the brake after 5 minutes(?). I was trying to look through the manual at the time (really, these things are not intuitive to search through) - wifi at the lake is non-existent to Google - and finally husband got in to re-park the car and it was totally fine.
Yes, I am scheduling an appointment with the dealership as it's time for an oil change anyway. Anyone have any ideas what happened? I can't figure out why the parking brake wouldn't actually disengage; I wondered if Hill Assist played a part, but surely it wouldn't affect the parking brake like that. I'd hate to think it would stick like this on a hill! I might live in Kansas, but do periodically park on an incline (my own driveway, for instance).
