Vehicle Shudder problems of the 2011 Dodge Charger

I was driving my vehicle straight down a city street at 36 miles per hour through an intersection light and my car began to shake really hard and the car began to drop speed on its own, I went to press the gas to acelerate and the egine light began to flash and the air conditioner started blowing really hot air and I lost all power to the vehicle. I tried to push the gas to turn off the busy street but I had no power so I had to pretty much coast to the nearest place to get out of traffice. Once I pulled over into a parking lot the car started to have a smell as if something was burning underneath the hood, at that point I put the car in park and pushed the off button, I sat a few minutes then tried to restart the car but it would not start and kept making a noise so I turned the car off got out and got my toddler out of the backseat and called my husband, he arrived about 10 minutes later and tried jump starting the car but it would not start and was making a weird noise when pushing the start button, at this point I figured the car stopped due to the alternator recall that was issued so I called my insurance company and had the vehicle towed to my local Dodge dealership where I had a diagnostic done on the vehicle and was told my engine is completely burned up due to lack of oil which is not true becuase I checked the oil dipstick 2 days after it had been sitting at the Dodge dealership and there was oil in the car and no oil leaks, I just had an oil change in March of this year (2018) so I believe my engine was burned up completely due to the alternator and a circut shortage cased the car to over heat and burn the engine, I need this to be investgated to see if this is secondary to the recall so that I can see if im responsible for the damages or not because now I need an entire new engine which is over $8,000 in costs.
