¿Qué le pasa a mi coche?
What is happening with my car? I don't understand this construction. ¿Qué le pasa a mi coche? Why not ¿Qué pasa con mi coche?
What is the le doing there, what about the a? Gracias.

I studied a similar form in my spanish book; I had sentences like: "Qué le ha pasado a ella" "What has happeneed to her." etc.
"What is happening with my car" is also the same as "what is happening to my car." So we have the occasion to use "a mi coche". But apparently, when you use a indirect object pronoun or the like, you also need to use "le" as a complement or something like that. (I have been told that it's not proper grammar to say things like "Ella dice el secreto a él", that it needs to be "Ella le dice el secreto a él")
I'm writing this from the top of my head, so, it may not be perfect, but I hope it helps.
Jeezle I have been thinking about your question about the a and my view is that the a is not the same personal a used in sentences referring to people or to pets:
e.g. Siempre das de comer al perro a las cinco de la tarde
You always feed the dog at 5 o' çlock at night
but the a used in constructions meaning to
eg ¿Puedes ayudarme a estudiar? = Can you help me to study?
So in your sentence, I believe that it is used to mean: What has happened to my car?
I have to be honest I do know why the le has to be there Kela maybe correct about that lets wait and see what the natives say 
I hope that helps
the first is what happened "with" my car. the other is whats happening in regard to "it" (my car) both are correct
I guess I wouldn't think about using an indirect construction like this with a car and not a person or something. I still think con sounds better.
Gracias.
