Today my '09 MCCS's brakes went crazy! I was driving at 33 MPH on a straight dry paved road and all of a sudden I hear a faint squealing sound that gets louder and louder. Then I start feeling my brakes going on and off very rapidity and my car is jerking very hard. I pull off the road and look at everything but nothing is apparent other than the brake rotors are very hot. Got back in and started driving; everything behaved normal so I drove the remaining 10 miles to home.

The weather and roads were dry, my driving was normal, and the road was clean and paved. My MCCS has 1,123 miles on it. What happened?

Sounds to me that the ABS turned it's self on for the heck of it.
Did you turn off the car when you got out to check?
Prolly reset the CPU and went back to normal.
If it happens again, I would take it in pronto as it may be a bad caliper, making the ABS think you are emergency braking.

 

Sounds to me like your E-brake was slight engaged.
