2004 Ford Focus loud noise while driving and engine coolant leak. Suggestions as to what is wrong and possible cost for repairs? - 1

Added (1). Not even at 100k miles yet and I have been experiencing a loud winding/ rumbling nose coming from what sounds like the middle/ back of car. Sounds like a plane taking off. Also been dealing with engine coolant like as well. Loud noise is probably back left bearing because winding stops when taking left turns. Suggestions of what could be wrong and approx. Cost?

Ford Focus 2015 won't start

I have a 2015 Ford Focus. Well taken care of with not many issues. I drove home last night. And this morning I went to leave for work and it won't start. All the lights came on. The low windshield washer fluid notification came up. But it wouldn t turn over. My miles were at about 60k, but everything came up as 0 this morning. And my clock said it was 12:00, when it was 6:30 am. The lights flickered and the radio came on but when I turned the key to start the engine it wouldn t turn. You could hear a tick or clicking in the engine like it's trying to start but just can't. I've read that it could be my starters. Also I've read it could be my computer system, or my TCM could be bad. Is there a way to test or even fix it before I tow it away?

2012 Ford Focus SE AUX system problems?

I own a 2012 Ford Focus SE, which is a hatchback. Lately, whenever I press the AUX button, it goes to sync for a second and then it reverts to radio. It's maddening. I tried parking my car with the engine running and turning it off and back on again, to no avail. Is it possibly an electrical issue? I have no idea if these two things correlate, but my window, which I roll down often to show my ID, stops functioning sometimes and stays closed. I know that it's not stuck, because it will randomly stop working and then start again. Are these two things being caused by an electrical issue in my car?
