Battery Cable problems of the 2009 GMC Sierra 1500

I purchased my truck about 1 year ago and it had 32,00 miles on it, it now has 40,000 miles. Everything was fine with it until about mid-April. I was driving to kalamazoo to see my daughter on I-94 around 72 mph with the cruise control on. I turned on my left turn signal to change lanes to pass the person in front of me and to my dismay my speed dropped drastically as the cruise control disengaged. This happened several times on the way to kalamazoo that day. It also got worse on this trip, sometimes the door locks would lock and unlock, all of the lights on the dashboard turned on and off and every time anything happened the speed dropped, which to me is a safety hazard and should be part of a recall. When I got home the next day, I called levalley GMC to take a look at my truck (where it's been serviced since purchase). When I explained the situation to them, they claimed they never heard of it. That's strange because if this situation is googled, there is a lot of information about what could be wrong. Lo and behold a day and a half later my truck was fixed at a cost of $1069. 71 for diagnosis and 3 cables, all positive and negative battery cables. I consider this situation a serious safety issue. I sent a letter to gm customer service. Lou contacted me and left a voice mail with case number 8-4206988703 (6/4/18). I called customer service and spoke with toni also 6/4/18. Toni reviewed the case and asked what I was requesting. I told her that this is a very serious safety matter that should be addressed and I would like to be compensated somehow. Toni stated that there is no recall for this situation and there is nothing that she can do. I told her maybe there should be a recall and I again stated that this is a serious safety issue.
