Oil Pump problems of the 2014 Jeep Cherokee

I purchased my car on 10/1/19 with 98,000 miles. A few short days later my car started driving horrible. Shaking,bucking, jerking, hesitating to accelerate and shift and my engine light came on while driving, scanned it and was showing p0520 oil pressure sensor. That was replaced. Car was still driving the same and 3 days later while driving my engine light came on again, this time code p06dd. Brought my car to the mechanic where he had it 3 week. My oil pump was replaced with a new oem pump. The very next day while driving my engine light went on again, throwing the same code p06dd. Brought back to the dealer where my car was low 2 quarts of oil. Was told to bring it to Jeep for recall and diagnosis. Jeep has my car for 4 days, completed the recall but was unable to diagnose my car. Upon leaving the Jeep dealer my engine light came back on and now my car was stuck in safe mode and would not go over 60mph. I brought my car back to the dealer where I purchased it. They had my car for two weeks and replaced my engine. I picked my car up on 12/6/19 from the dealer I purchased from, who just replaced my engine. With a new engine, the car is still not driving right. It is still shaking,bucking, jerking, hesitating to accelerate, hesitating to shift out of all gears. I had my tires balanced 2 times. On 1/13/2020 my car while driving on the highway went into safe mode again. Not going over 60mph. This time no engine lights are on. I brought it back to the dealer I purchased from, they hooked up the computer. . Which showed no codes. It took my car out of safe mode but did not fix any of the problems I'm having. Today, 1/21/20 my car went back into safe mode while driving. Will not go over 60mph and there are no lights on the dash showing there is a problem. This car is not safe. I am a single mom with 2 kids and I will not jeopardize mine or their lives in this vehicle.
