Brake Grinding Noise problems of the 2012 Ford Focus

I have 2012 Ford Focus with about 85,000 miles. Since 2014, I've had my tcm reprogrammed several times and then replaced in Dec 2015 under the extended warranty after it completely stopped working. I brought my car to Ford again in July 2017 because my steering locked up while I was attempting to back up in a parking lot. I was told it was the epas system, and it would cost about $1,800 to replace since it's not covered under warranty. At their insistence, I paid for the replacement. I also made a complaint with the national highway traffic safety administration at that time. Since July, I've have been back to three Ford dealerships - first two times because of a grinding noise (they couldn't diagnose it then but have since said it is my clutch) and a second time this past Tuesday (9/12) after my car basically short circuited in a parking lot on Monday and it started lurching forward while trying to reverse. . . Simultaneously my breaks locked up and my steering locked up again (my sound/radio display/front buttons were also intermittently not working). Jc Ford did some "reprogramming" but said they couldn't duplicate the issues and told me my clutch would need replaced eventually but Ford would not cover it until it got worse. They told me these problems were unrelated despite me insisting they all felt similar while driving the vehicle. Yesterday (weds, 9/13), while attempting to turn onto a highway, my car again "stalled"/short-circuited (not sure what exactly happened - but the same thing as the previous times) and my breaks locked up and I couldn't move the vehicle from the middle of the road. Fortunately, I was able to get it out of the road after turning it off and on several times. I immediately took it to a Ford nearby and am waiting to hear if they find anything else. I am now scared to drive my vehicle despite Ford looking at it and "fixing" it several times.

When making a left turn from a main road onto a side street I encounter massive grinding noises coming from what sounded like my left front tire area. I thought maybe it was my imagination. From then on there is intermittent noises coming from that area (sounds like plastic rubbing on something) I took it to the dealership on sat, 7/14 they did a visual safety exam and found nothing wrong but they did rotate my tires just in case. I am also experiencing a grinding noise when pressing on the gas from about 0-20 mph (going straight) (sounds separate from the grinding issues under the tire, but I am unsure if this is related. I am scheduled to take the car back to the dealership on 7/19 to see if they can find a problem. Very frustrating as this car is just over 6 months old!.
