After asking my S/A for a better explanation, and after he spoke to the tech, they had to replace the receiver unit, apparently the sensors did something to the receiver and froze/fried it. They didn't want to put in a new part and get it fried again hence the new sensors. The tech also told me that as long as they are the OE style they will work, I guess the ones Tire Rack and some other companies sell are OE so they have no problems. My S/A also said they take these seriously since its a safety feature on the car and they wont be liable for someone getting injured because something wasn't working.
