While driving 30 MPH on a city street the drive shaft of my 2012 GMC acadia fell off. I was able to quickly move my vehicle into a parking lot to avoid further damage. Upon inspection with the tow truck driver we noted that the AWD drive shaft fell from the under carriage of my vehicle. It seems that all six bolts had fallen off this drive shaft.
