    2010 Mazda CX-7 loss of acceleration

    I have a 2010 CX-7 and was driving down the freeway yesterday at about 65-70mph and all of a sudden heard a loud whine noise (sounded like a woosho of air mixed with a whine) and lost all acceleration. I pulled off the freeway and the car was still drivable, just really bad acceleration. I can no longer hear the turbo spool up. No oil leaking, no white smoke, no check engine light. Any ideas?
