I ahve had my 2012 Terrain in the shop 4 times now, I was told the last time that some degree of static is normal. Hmm, well, I now drive down the road playing my radio while videotping the static on full blast, I would call it music but since all I hear is PURE static at most times thats what I will call it.. Took it back today, and played the video footage to the service advisor and also to the tech, they re callibrated it, said the calllibration was wrong, I was super excited that they finally found an answer, pulled out of the garage there and it was back to the usual crap! ON top of that weird things have been happeneing, NONE iof which can be found or re created, The screen freezes up , it says diualing, I am not using the phone at the time or it freezes on please try again, Um, try WHAT again, I am driving and just started my car.. also, my screen goes very dim all of a sudden like if u were to turn down the dimmer switch but I havent touched the switch and it doesnt come back until i turn car on then off. Alaso, my car feels like it is going to stall then it jerks real hard, they cant find that either.. It gets so frustrating..
