I'm trying to figure out what is wrong with my car and hopefully get a ballpark idea of how much it will cost to fix it. About a two months ago my check engine light came on. I scanned for the code and it came back P1450 which is for the EVAP. I took it to a local mechanic who claims they fixed it but the light came back on two hours later. When i called to complain they told me to take my car to a ford dealership because they thought they fixed it and if they didn't, they didn't know how. It doesn't seem to really do anything being on except whenever I get gas, my car won't turn on for like 5-10 minutes. But then last night, I was in the middle of driving (about 35-40 mph) and my car just turned off. The dash light came on saying the car wasn't in park (obviously). I pulled over and turned the car all the way off and back on again and it has been fine sense. It scared the crap out of me though. The other issue is that about a month ago, every time I pulled out of a parking space or turn my wheel slowly, this god awful noise came from what sounded like the front passenger side of my car. Intermittent steering squeaking a friend called it. But it suddenly stopped about two weeks ago. The only think I hear now is an occasionally creaking noise when I drive coming from under the car. I had a friend lift the car up and look and he found nothing wrong with it so I think it might be okay but I'm still a little concerned. Any ideas would be helpful! I've only had my car a little over two years and I'm only the second driver. Less than 80,000 miles. I got brand new tires in January, a new wheel barring in September. I don't beat her up, just my daily driver to and from work which is only about 20 miles each way.
