Brought Yukon in to koons GMC in manassas, Virginia in 2012 for two recalls which I was told were both done along with getting an estimate for $3300 for largely an intake manifold. I have called GM Corp and been told many times over that past two years as more cars have been added to recall lists that there were no remaining recalls for my vehicle; now GM corporate says the wheel sensor recall (necessary to avoid low speed crashes) was actually never performed and GM corporate cannot explain why I have been told by both dealerships in the DC area and GM corporate over the past two years (exceeding 10 total calls) since that there were no remaining recalls left to perform on this Yukon. Presumably the headrest recall I brought it into koons in manassas, va as a second afterthought to the wheel sensor recall was the only thing they ended up doing other than giving me an estimate for over $3300 for work that has never needed to be done. My unanswered question to GM corporate was "I's this how your going to handle the ignition recalls"" additionally, GM claims to be unable to answer the question of whether my ignition switch is the same in design as any of those that have been recalled. Do americans citizens not have the right to at least that much "proprietary"-protected information from GM" GM corporate's specialist claimed to object to my mentioning that I, too, might record the call. Koons also never noticed that the previous owner had broken out the ABS light because prior to the recall (which should have later tipped me off that they did not actually clean the wheel sensor and check the ABS light since it was not on the $3300 estimate of necessary repairs), because nobody really knew then why the ABS light would stay on. I believe this was a retaliatory act. I mentioned to koons snd GM corporate before service that I was disabled.

The first time my engine stalled was back in 2001 on the middle of the 101 freeway in los angeles. I took it to the dealer and they stated it had to do with a chip. They replaced the chip and I haven't had a stalling problem until now. My car has stalled twice in the parking lot and once on the freeway. I am very upset that something so serious has not been fixed and was only a temporary fix. It seems to happen more when I have the heater or ac on and if I come to a stop.

While traveling at approximately 50 mph vehicle passed under power lines coming from a tower which caused radio/ guages, and engine to operate erratically and then stop functioning. This event has occurred twice when passing underneath these power lines. Please provide any additional information/attachments.
