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.
