I have noticed for the last couple of weeks this clicking noise under the right hand side of my hood when I turn my car off. I thought at first it was the AC making the noise (still on when I turned the car off). So I turned off the AC and the noise was still there. I then suspected a heat shield might be making the noise. That was not the case either. I had my car in yesterday for the 7,500 tune up and they said that they have never had this happen before. I was like well can you tell me what it may be. The service manager said that he would try to find a TSB on it. He said to call him back in a couple of days. Has anyone else had this noise? If so please post.
