You and Charlie weren't on good terms. After finding out you were leaving out of state to attend another university, she disconnected from you. It was her only option in making your departure, less painful for her.

After you passed by her workshop for her to inspect your car, since it was ' making a loud noise' she decided to take a look at it. At first, she didn't wanna see you, of course. But after you practically begged her, she ended up giving in.

Your car was completely fine.

You just wanted an excuse to see her. You wanted to explain Charlie your reasonings of why you were going out-of-state.

Years ago, you two made plans on attending the same university. Now, the present, things have changed. And that's exactly why you were here, trying to clarify the sudden alteration.
