OK so the other day I am driving out of my neighborhood to the gym when i realized i forgot something. So being the random person that I am i decided instead of turning around I would drive backwards to my house. (yah go figure)

So as I am turning backwards onto another street i got to hit the breaks and the STABILITY SYSTEM comes on on the DIC and the brake pedal goes completely to the floor!!!! Scared the **it outta myself.

First of all I can't figure out why the stability system kicked in, the car wasn't skidding and I was prolly doing about 20 mph. And when the system kicked in should it override the brakes like that? It didn't feel like the brakes were working at all, but it also didn't feel like a bad master cylinder seal (that'* how my last truck met it'* demise, along with the cadillac infront of it).

Any ideas? the brakes are working fine now, and i've decided not to drive in reverse back to my house anymore

I laughed out loud when I read your post. I've done the same silly thing, backing all the way up the street, even turning a corner, going back to my house. Neighbors thought I was freekin' nuts. Only thing, I didn't have a car with stability control at the time.

I think this is Mama GM'* way of telling you NOT to act like an idiot and drive over 15mph in reverse. I call that NaderThink.

Try it again and I'll bet she does the same thing. Only this time find yourself a place where you can cause no danger to anyone else or yourself, AND YOU CAN'T BE SEEN.

.................and another thing. I know how the system knows you are goofing off, but exactly how do you know how fast you were going? Did the speedo register -20mph?

sensors my friend, sensors

The sensors in your head can't be THAT good! Did you see a "-20mph" sign on the back of your eyeballs. Gawd, now I'm really getting silly..............but as the carrot said to the mold, "Hey, you sound like a fungi".

even in reverse the speedometer is going to read positive. I've gone 40 MPH in reverse before... that was pretty stupid.
