Hello there,

I have a 2013 G37 sedan with 25k miles on it. Everything is stock. While driving, I turned on the AC. I heard the compressor trying to engage, but it failed and stopped for a second. It tried to engage again, but the same thing happened. The third time, it engaged without any problem and I started feeling the cold air coming in. The whole thing took like 5 seconds. Should I be worried? I would appreciate your input. Thanks in advance!

 

Same thing happened again today while I was at a red light. The car shakes a little bit (nothing crazy, but I can feel it) when the compressor fails to engage. Any thoughts?

 

by your own description it sounds like the clutch is slipping. time to replace the compressor.
