I've had my beautiful Element 6 weeks today. I decided it was finally time to turn the remarkable stereo down and just listen to the engine, etc. What I discovered is that when I first turn on my A/C, I get a grinding noise. This grinding seems to last about 5 seconds and then it quiets down. Doesn't do this everytime it is turned on but does do it most of the time. Anyone else exerience this? Is a visit to my dealer in order?
