Brake Sensor problems of the 2003 Cadillac CTS

Was entering the on ramp on to a freeway and just tapped the brake and noticed and heard the left front tire grind and the steering wheel pulled to the left real hard. I was going into a blind under pass and thought that if it seized up around the blind corner I would surely be in an accident. I first thought that a stone chip was in between the brake and rotor. The car was towed away to a aaa location about 3 miles away. The service station then took it out around the block and was not able to duplicate. The put the car up and the lift and could not see anything that was wrong. Then I took them out around the block real slow and the left front brakes would grind away. They tested it and could not find anything wrong no error codes. They I said could drive the car home from san diego to south orange county not didn't make it a block away before it locked up the left front tire. Was able to limp to marvin k. Brown auto center about a mile away and it was there for two weeks and $500. 00 for a steering sensor replaced. Then it continued to happen and the Cts was taken to tustin Cadillac and they tried to correct the problems after spending 2 days at the dealer and $1700. 00 later the car continues to have not only the left front but now it is the right front. The brakes continue to activate on both the left and right front at anytime at any speed. This last time it felt like the left rear activated, the car got out of control every one around me backed off. I have been driving the car through the locking of left or right front tires and it does say ding and read " check stability system" this car it no longer save to be driven and I was told the last part to fix it is "obsolete" the only thing that might work is to disable the "stability system" by unplugging the fuses on in the trunk on up front.

While driving at a steady and even speed my car would suddenly pulled to the left as if the left front wheel had the break apply. Almost instantly my "stability system engaged" display would go on and the car would correct itself. This went on to become a regular event with each time I took the car out. The most it occurred was 30 or so times in a 90 mile trip, but it happened regularly on local 2 mile trips to the store. Sometimes it would be more severe than others . In addition and occasionally, when the breaks were applied, there would be a "loudish" crunch sound and resistance to foot pressure that would give way after the initial break application. There was also a vibration "buzz" through the gas pedal when this all would occur. The first time I took the car to the dealer they could not find anything wrong or duplicate the problem. I took them information I had found on the web about the problem and they checked their service bulletins for a problem. It was fixed by changing a steering sensor at a cost of $430.

At highway speeds while driving straight stability system engages when applying the brakes. It only feels like there is brakes on the left side, pulling the vehicle violently to the left. . Dealer fixed the vehicle, replaced sensor in steering wheel part # 26059045.
