On 24th of Dec 2014 while driving on a four lane hwy at about 8pm my brakes got really hard then I saw my brakes light came on it was not a good feeling thanks god the street light was green cause if it was red we would be having a dir convo right now, anyway I pulled in a parking lot at maybe 15 to 20 mh then I put it in park pull up the hand brakes and turn off the car, I stayed there for about an hour and half then I tried the car again it came on like nothing happen. . . . . . . . . . . . . . Am telling u I don't wish this on anyone. . . . . When I first got the car in 2007 it shut down on me I said I maybe did something I still can't figure it out but it never shut down again.
