I was driving down the road, and i went to hit the breaks, and the breaks went to the floor, i had no breaks!!! i tried 3 more times, and the breaks came back, but now they are really touchy, and the ABS isn't working anymore.... i took it to the dealer, and they said it was a wheel sensor, they got the abs light to turn off, but now it did it again, but this time the abs light didn't come on... what's going on? and how hard is it to fix? please help!!!!!!!

 

If it's a wheel sensor, it should be covered under warranty unless your car is over 60,000 miles. And if it's a safety issue, the dealer shouldn't release it to you until it is fixed; they can incur a huge liability if you get in an accident.
