car has been acting up. at idle the car feels weird. the nav unit keeps getting a message saying command cannot be used at this time, that happens wen you put a disc into the cd slot. the gastank light comes on says cap is loose when its tight as can be. the seats dont go back n forth anymore when door opens or closes. plz help thanks in advance

 

disconnect the battery for half an hour then read the thread stuck at the top of this forum. inside it you will find the "resets"

 

Have you had to jump start the car lately by any chance due to a weak battery?
