The brakes feel like the pulsate wgen you start to press on them. Then while engaging the brakes it will feel likes its grabbing then it releaes and the pedal feels like it has no pressure in it. The cruise control stopped working, all the lights are on for the brake system, and now it has a long high pitch beep when turning the car on or applying pressure to the break pedal.
For about 6 months or longer, the cruise control on this car has been operating erratically, when it wants to it seems. The problem always seemed to be that I couldn't turn the system on. Now, however, when I am sometimes able to turn it on, and set the speed, the problem becomes that the stalk on the lower right side of the steering wheel will lose it's connection and the movements of the stalk become inactive. This is very surprising if you're planning to slow down, speed up or more importantly hit the cancel button. The only thing to do is hit the brakes. This is very distracting and potentially dangerous.
