So, once in a while I hear a very brief, but noticeable squeak, similar to a belt slip sound right after start up.

anyone experience the same?

 

I have, and it's driving me nuts; i don't know if it's the auxiliary belt that drives the AC or something more than that?
did you fix it? what was it if so

 

No the car was in for service B but "the guys I have here are just oil and wiper guys" so they didn't look into it.

It it is annoying and hard to pin point.i assume if it was a driving belt it would squeak right at the REV on start up but it is usually delayed a split second and near the end or after the initial start up REV. Is the same for you? This makes me thing its AC belt but..It's intermittent and the ac is alsway on auto.

so essentially no, haven't figured it out yet...
