Why is the ABS engaging when it shouldn't Dangerous prevents safe steering.

What is your question?

At least three time the ABS light has come on twice now I have had the following problem. With the light on the ABS is engaging while driving and with it the steering /wheel is affected. The last time it was repaired the reason reported was a damaged/cut wire..the first time the repair shop checked it they said there was no problem until it engaged again at a busy intersection almost causing an accident. Took it back to the repair shop, they looked thoroughly and found the broken wire. This was at least a year ago now it is happening again. How many complaints do you have to get before this is improved (thicker wire or other solution)?
