i noticed the same thing, but attributed it to just being a Very heavy car.... im curious to know as well tho, but i suspect that what u and i are experiencing, Everyone is experiencing, and probably isnt a problem at all....
I had never used my parking brake but the brake light came on this morning. I remember someone else had this problem. I pushed in the parking brake and then released it and the light went off. Hopefully this is not the sign of a problem.
I have on several ocassions "touched" the parking brake pedal with my foot when entering the vehicle producing the warning light when I start it up. I just pull the release lever and the light goes out. That puppy is sensitive! Depression of the pedal 1mm must set that warning light!
I have noticed that once in awhile, my brake light is on...Has anyone noticed, if you even "tap" the parking brake (which may happen when you exit) it will trigger the parking brake....I mean, even a tap...Can someone check this for me? perhaps I need an adjustment--or is it a design flaw???
It happened to me about 3 times in first 2000 miles but not recently. Brake release turns it off easily. I have not been aware that I actually bumped the brake to make the light come on and I have not been able to make it come on by deliberately bumping it.
"Easter Egg Mode" is achieved by pressing the "N" button on the right inner portion of the steering wheel with the music note button on the left inner side of the steering wheel - hold both down together for 6 seconds, and you get detailed info about what's going on with the car. It's really cool!
I haven't had the light come on unexpectedly, but my parking brake is not holding the car in my driveway unless I give it a good kick. Usually those light problems are in a switch mounted next to the pedal. We'll see if the dealer fixes mine today.
Took my "C" into the dealer yesterday for oil change, filter, and rotate wheels. Asked also why my parking brake is so sensitive that the light comes on very often.
Advisor said that after checking, my master brake cylinder was slightly low. It was topped off, no further problem.
Related, I asked why I practically have to stand on the parking brake to get it to hold, Advisor said that the brake is a small drum inside the left rear wheel only. The cable was adjusted as far as it could safely be tightened without causing the brake to drag. Still isn't what I would call a valid emergency brake. Maybe PARKING is exactly what is meant. Go figger.
