When it starts doing this I turn the AC off and everything goes back to normal, wtf? I sent it to the dealership about a month ago and they found nothing wrong with it at all. My girlfriend drove it the other day and it happened to her and now she refuses to drive the car, lol. has anyone experienced this before? I'm at my wits end and I'm having a friend take a look at it tomorrow. But if he can't find anything and the dealership tells me its fine what am I supposed to do? The last thing I want is for this problem to cause an accident but its been damn near 100 degrees everyday where I live. Any thoughts? I think it may have something to do with the AC compressor?
