Vehicle Shudder problems of the 2005 Saturn VUE

While driving between 30 and 40 mph the vehicle experiences a vibration in the rear of the vehicle. The vehicle was allegedly repaired by a gm dealer at no charge. The problem was not resolved. At least 4 other attempts to have gm repair the vehicle were refused by gm dealers even after the repair bulletin was extended into 2015. Not satisfied I contacted someone at gm and asked for a referral to another dealer in my local area. I received it and took it the referred dealer and explained the situation. After inspecting the car they acknowledged the vibration issue but said that before anything could be done the engine block mounts had to be replaced at a cost of approx. $1000. I thanked them and took the car to my trusted regular mechanic. I asked him to check the engine mounts (without telling him what happened at the gm dealer) and give me a report. Upon inspecting, he stated there was absolutely nothing wrong with the engine mounts. At this point, frustrated and angry with gm, I basically gave up. Furthermore, this occurred at the time of the gm ignition switch recall debacle. Our Saturn Vue also has a problem with the ignition. On multiple occasions we were not able to remove the ignition key from the ignition switch without pliers and a lot of time. It took over an hour on several occasions to remove the key. We found information online where gm acknowledged there was a problem with the Vue ignition switches, but several attempts to have the switch replaced resulted in refusals by gm dealers. I thought this was odd given the huge recall of ignition switches by gm at the time. We basically received the same treatment concerning the rear end powertrain vibration after the initial repair even though the maintenance bulletin extended the repair period. There was an alternate repair if the first repair failed, but the dealer wouldn't honor it.
