Mine's still at the dealer. Not yet fixed.
Looking at the history of your vehicle, the only record relating to the engine looks to be the 'ticking noise while hot engine is idling'. Did the previous owner ever fix the problem and if so, what had been done? Do you think the engine shaking may have something to do with it?
