Battery Cable Problems of GMC Acadia

I'm logging these issue as I have now come to realize that the issues we have had with our 2008 GMC Acadia are very widespread among owners. Very early on in the life of the vehicle approx oct 2008 we began seeing small amounts of water inside the cabin. Water would drip along the windshield occasionally, no action was taken as it was not consistent or so we thought. On multiple occasions my wife would complain that the vehicle would "cutoff" or "die" generally at slow speed in areas such a parking lots when turning, however the dealer was unable to re-create the issue so no repairs were made. One day this summer (2014) my wife was unable to start the vehicle, it just would not crank. On taking it to the dealer the vehicle was diagnosed with a corroded battery cable that ran from the middle of the vehicle to the starter in the engine bay. Cost to repair $1,200. In approximately June 2014 the vehicle began experiencing a slight rollback when placed into drive. At first we didn't think it was an issue as it didn't get worse with time. However by October 2014 we got a check engine light, diagnosis transmission failure cost to repair $4,890 after a $200 discount.

The main battery cable running from the battery located behind the passager's seat was resting on a bolt from the frame. The threads from the bolt cut through the battery cable and shorted out the electrical system causing the floor matting to catch fire while the vehicle was in motion. The engine shut down, causing a loss of power steering and brakes. Since it was the main battery cable the connects directly to the battery with no fuse, the short continued to spark. In the particual vehicle the battery is located inside the vehicle, below the passager side rear floor. The positive battery cable runs from there to inside the engine compartment to the alternator, with no fuse in between. I took the vehicle to the dealer and they said it was not a warranty issue. I raised the question with them about a recall and got no where. I did some searches on GMC blog sites and this issue has happened on a number of other vehicles, one leading to a wreck. Luckily I was at a stop light turning when it happened to me. If this would have happened on a freeway at freeway speeds, the story could have been much worse.

I am on active duty an active duty military member. While attending a military school, I purchased a new 2007 GMC Acadia from a GMC dealership nearby. After the course, I served a year at a military station in another state, while there, my vehicle was serviced twice for recalls by a GMC service center nearby. One of the recalls was to fix a defect in the sun roof that was causing water leaks. I had the vehicle serviced in 09 while the vehicle was still under warranty just before shipping for a 2 year overseas assignment. At that time, I identified some electrical issues. Soon after my arrival to my overseas assignment, more electrical issues developed along with mystery water leaks that were saturating the carpet and causing mold to grow inside the vehicle. There was no gm service center in that country so I had to live with the leaks and electrical problems. Finally after about a year, I had a minor accident where my tire hit a guard rail doing about 10 mph. All the air bags deployed but there was no other damage to the vehicle. At this point I quit using the vehicle. The seat belts didn’t work, the ac and heater didn’t work, the left blinker didn’t work, the engine would not shut off with the key, the battery box behind the passenger seat kept flooding with water and I had to disconnect a battery cable every time I parked the car to keep the battery from dying. The vehicle was unsafe. I am now stationed in the us and have shipped the vehicle back to the USA. I am now trying to resolve all these issues with a local gm service center but I am being told by that service center that the vehicle is basically totaled with only 60k miles but since it is now out of warranty, I am responsible for the repairs.
