I've had mine just over a month now. I have about 2300 miles on it. So far no big issues. I did have a vibration or something in the dash somewhere to the left of the steering wheel. It was annoying. But I never did figure out where exactly it was coming from, and I haven't heard it in a few weeks now.
I know the first few times I checked the oil it seemed good to go. I checked it tonight and it was a little below the midpoint between the low and full lines, but the car was parked on a slant. I don't know if it was enough to cause that, or if it has burned a bit.
