Speed Control Cable problems of the 2007 Chevrolet Tahoe

We purchased a 2007 Tahoe in August 2012. Since this time, my wife and I have both experienced multiple electrical starting issues with the vehicle. A jump start or boost will often allow the vehicle to start. However, there have been situations where we have not been able to find an available boost. We have been stranded in parking lots, family vacations, work, and our kids games or practices. As noted in many of the complaints, the starting problems are intermittent and there are times a boost will not start the vehicle. In fact, we even began to lose power traveling at highway speeds during a family vacation this past summer. This is very disturbing issue for gm and their apparent inability or unwillingness to correct the problem. In addition to the starting / loss of power problems, a cracked dash and faulty cruise control is something that should not happen with the technology available. Based on a review of the complaints, it may likely be a battery cable issue. Gm must recall this known problem!!!.
