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. Initially the GMC dealership refused to repair my vehicle which is under a 5 year 100,000 warranty as they said the vehicle must have been sabotaged but they could not provide any proof. I pointed out to the service manager that there was no evidence of any sabotage and let him know that I would be pursuing a warranty claim with GMC corporate as well as MA dept of consumer affairs. The service manager called me back about 30 minutes later to let me know that the general manager agreed to repair my vehicle this one time was while responsive to my request did not appear to address a potentially larger safety issue. I inquired about reporting this incident to the nhsta and they did nothing which is why I am contacting this organization directly.
