November 13, I went out to start my 2008 Yukon and the lights, door locks, and cd player began to flicker and then shut off. The gauges also began to flicker erratically, then the car would not start. Later in the afternoon, my husband and I pushed the car out of the garage and when the Yukon went over the lip of the garage into the driveway, the bump caused all the lights, radio, and back dloor latch to come on or begin working. This occurred several other times over several weeks and included the rear door not working or the powerlocks not working with the remote. We took it to driver's automotive in the woodlands, texas, and had them run a diagnostic on the vehicle. The auto repairman checked the battery and cables and said nothing shows up in the diagnostic but eventually they did replace the cbm. We paid $ 718. 00 to replace the cbm, trusting that was the problem. The vehicle started up fine for several weeks after that but since December 21, the Yukon has duplicated the erratic light flickering, radio and ignition not working, the rear door not opening (using the car remote as well as the power button on front console inside vehicle). In addition, the doors won't lock and the gauges flicker uncontrollably and the vehicle won't start. We are very concerned. A diagnostic says nothing is wrong but with the electrical issues, I am fearful of what could happen.
