I have had my 06 for a month now and i really havent had any serious issues, however from day one i felt like upon start up, any start up hot or cold, the starter sounds like its dragging ( slow crank ) but it fires right away. After reading about battery maintinance i put the battery on a battery tender, checked the battery voltage hot and cold, checked the output of the alt, and all is withen acceptable range. The car is outside and covered and hooked to the battery tender 24-7 when not in use, it has been very cold in the north east and upon start up on the colder mornings i hear what sounds like the solonoid clicking in and out ( as in a dead battery ) just before it fires. and it has not failed to fire off. having it on a float charge the battery is maintained at peak voltage so i am certain its not the battery. Is it possiable the starter is on its last legs.
