general problems of the 2012 GMC Acadia - part 2

I opened the rear tailgate and while taking an object out of the back of the vehicle, the tailgate came crashing down on my head with great force. After physically recovering, I tested the tailgate and the issue repeated itself. I called kitahara GMC in fresno, CA and scheduled a service appointment. Kitahara replaced the parts, but I was told that it is a wear part and that because there are no recalls there is no way for them to guarantee that the issue won't happen again. I called general motors to report the issue and they offered $100 toward an oil change and tire rotation and claimed that they do not issue recalls. I am reporting this issue to the NHTSA, because I fear that this default is extremely dangerous and could cause severe injury or even death depending on the situation at the time of malfunction.

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.

As power liftgate was opening, I started to retrieve items from back of vehicle. All of a sudden, as the liftgate reached the top of it's opening range, it immediately slammed down about 12 inches, hitting me in the head and causing severe neck pain, and continued to travel down. At this point, I am unsure what the actual defect is as I have not taken the vehicle to gm yet to be diagnosed. In googling this issue, I came across another person that had the same thing happen. "I made a report to the NHTSA. The number is 10464171".

The contact owns a gm aftermarket air deflector (part number: 1927884) being used on a 2012 GMC Acadia. The contact was driving 70 mph when the center plastic tie fractured and caused the deflector to crash into the windshield of the vehicle. The manufacturer was made aware of the failure. The deflector was not replaced. The serial number and VIN was not available. The failure mileage was unavailable.
