Brake Antilock Wheel Speed Sensor problems of the 2007 Chevrolet Colorado

On 10/10/2012 I was driving at 30 mph and went to brake for a car in front of me and the brakes just grabbed and released and I thought I was going to hit the car in front of me. I noticed the brakes grabbing and pulsating after that didn't know if I was going o stop without hitting someone in another car or something also the abs fault light came on and off. I took my vehicle to the dealer on 10/15/2012 and the service advisor told me the right front speed sensor was bad and had to replace the right hub bearing & right front wheel speed sensor because the engineers at Chevrolet designed it wrong and that they made a kit to repair the problem it cost 930. 00 dollars in 2012. Now the left front brake is doing the same thing. Obviously there is a problem I have noticed other complains listed in the vehicle safety complaints just like mine I feel there should be a recall issued for this problem. Please investigate thank you.
