my 2009 journey makes the vibration also but the engine light does not come on. it feels like the front of the car is coming apart and the engine realy rattles started about 20000 has 35000 now nothing has been found have had it checked but nothing has been found also if we dont let idle for a minute or so when it is started and before it is put into gear it wont shift to over drive. you have to stop and shut it off then restart it then it will shift ok.
