Engine Noise problems of the 2012 Dodge Challenger

This is in regard to the Dodge t36 alternator recall. After the recall was announced, my car was affected. I want to add another report. In mid 2017, a higher pitch noise was coming from the engine. 2 to 3 months later, I took the car to my dealer who affirmed the noise was the sound of the alternator charging. The recall replacement part was not available. As long as I was operational, the advice was to wait. 2 months after the dealer visit, while driving one morning, my alternator failed, the battery was dead, and my engine died. When I left out that morning, a couple of the idiot lights came on which was weird. Then 15 minutes later, while in traffic on a busy road, the radio was glitching, many of the warning lights came on, power steering went out. I was able to move over to the right lane, though nearly sideswiping another vehicle in the process. The engine then just ceased. I was able to coast to a stop in a safe spot. No power whatsoever. Car towed to dealer. Dealer claimed battery, which was the original, did not die as a result of the alternator failure. To me, the timing says otherwise. If the battery was on its way out, this sure finished it off. Dealer installed a new battery and a replacement alternator - but this was the existing non-replacement alternator stock. Once the recall replacement part becomes available, whenever that will be, I will need to take the car in again to have that put in if it's a replacement part to the alternator. Otherwise, if it's a whole alternator unit, then they will swap out the existing stock new one I received. Dealer/mfr did not cover the cost of the new battery. They did replace the alternator at no cost.
