I was driving up the [XXX] north and where [XXX] merges to [XXX] I'm going 65mph on the far left side, and my dash starts beeping and reads WARNING STOP VEHICLE CHECK BRAKES. MY brakes go out, pedal to the floor sounding like grinding gears and doing some major damage, my acceleration stopped working. The [XXX] is merging on the left side so i had to avoid major traffic. I am a driver with skill as i dodge slowed and stopped vehicles, and get to the shoulder before [XXX]. I call for roadside assistance because kia says its free and its not. I was looking around the engine to see what the heck and unplugged the hybrid fuse and battery from back and suddenly it worked again and drive it home and right before I park I made a right turn, and it started beeping again, and this time it stayed this way. I almost lost my life, and I did lose my job because of it. GLENDALE'S CARSPRO KIA SERVICE DEPARTMENT IS THE WORST DEPARTMENT EVER!, they would not help me get a tow, I paid for the tow. THEY CHARGED CLOSE TO 5 GRAND FOR A REPAIR, Hydraulic brake booster module, AND A COUPLE HUNDRED FOR THERE HIGHEST SERVICE OPTION (Changing fluids, wipers, wash, detail, etc) this was a huge mistake and took nearly two months! My car had dust on it THEY DID NOT EVEN CHECK THE PRESSURE I HAD IN MY ALL 4 TIRES (EMPTIED UNTIL 25PSI) I started the vehicle and it started to hiccup as I idle I asked for the manager (a tall husky middle eastern guy with long hair and glasses). He replied "DOES YOUR CAR
