Mine used to do it erratically, not predictable. For me, it was a faulty ignition coil in cylinder number 7.

Mine was caused by bad engine mounts. After the mounts were replaced,the car ran just like new.

can engine mounts go bad after 15 months/19K miles of driving, though?

Best bet is to have it checked since you still have warranty? My dealer said these mounts on our car are not as strong. And they should have fixed that problem by now? It's also because the engine is so heavy also.

I'll get it checked out ... I have a feeling I'm going to get the "operating as designed" response...........
