NHTSA Complaint #11472241 — 2009 KIA BORREGO

I was driving in traffic with stop light coming up hit my brakes to slow down because of cars in front of me, I had no brakes/ no warning lights on dash. I pumped my brakes and was able to stop before hitting car in front of me. Local shop said master cylinder so I took it to local shop that repairs my car the last few years, they replaced Kia master cylinder, still no brake, replaced Kia brake booster, still no brakes, sent master cylinder back and reordered another new kia one it was put on and no brakes, had it towed to shop in Charlotte NC , no codes reading for problem so they said it must be the module accuator assembly. No mechanic knows what's wrong with my brakes because nothing can relay to their diagnostic machines. I have spent over about 13 hundred dollars so far and there is no way to find out what's wrong other than replace the entire brake system from wheels inward to the brake assembly and up to the booster and master cylinder because the brake assembly is not relaying any codes. I could of been in a bad accident because of my brakes failing.
