Car Will Not Accelerate Problems of Hyundai Elantra

My car had recently began to shake and buck violently while driving with no warning lights or indicators at 38,000 miles. Three weeks ago before a regular maintenance appointment at my Hyundai dealership where I bought the !car, as I turned over the ignition and accelerated the car began to buck and shake violently. As I pressed the gas, the car would not accelerate. I was in the middle of traffic in washington, d. C. So once I was able to safely move over, I turned the car off and back over. No shaking and continued as normal. Once I took the car in the following week, I was told everything was fine and made sure to mention the shaking and bucking and was told that they didn't see anything. The next day following service and receiving my car back, my car began to shake violently again. Still no warning light indicator. I returned the car to the mechanic where my coil packs were updated (I bought my car March 2017 and was never told about any recalls on coil packs that release late 2017 until this moment). Once I received my car back I was informed that everything was okay. Well it was not. The next day I'm driving my car a short distance when two hard shakes happened. One sounded like two metal pieces colliding. I pulled over and turned the car off and back over. The malfunction indicator light is now permanently on. I had to have my car towed and now being told it could be the transmission but no updates. Seriously unsafe and could've now been in multiple accidents although I've regularly serviced at the dealership I purchased my car.

When I attempt to start the car the engine turns but won't turn over. The car does this more often in very cold weather. Even in warm weather it will start sometimes and sometimes I have to try multiple times and sometimes it will not start at all. There are no check engine or other indicators that there is an issue with the car. The only other thing that may or may not be related that is different from what I normally expect is that sometimes the while driving, the car will not accelerate in a timely manner. There is a bit of a hesitation as if the fuel output is not increasing. This happens while I'm already driving (for example when I'm going from the access road and entering the highway or when there is a speed limit increase of some kind). I was told by a mechanic that the part affected is connected to other systems in the car that have an electrical component such as the fuel pump.
