Ok so I am driving my X yesterday and all of a sudden it wont go. It has power but will not accelerate. When I put it in park it would roll backwards. Looks like the transmission or a component of it. I had no warning. It literally just happened in the middle of the road. Has this happened to anyone else? I had it towed to my indy but it will be Monday before I find anything out and I am scared to death of what it may be and how much it will cost to repair. This car only has 69K on it.
