Adaptive Cruise Control problems of the 2018 Jeep Compass

My husband purchased me this car about three months ago and it has been nothing but hell for me. My car won’t stop swallowing oil. I had an oil change a month ago and I’ve already lost a little over half of the oil, and there’s no obvious oil leaks under the car. My tranny also won’t shift past a 45 minute drive. It shifts rough for the first half hour but after that it progressively gets worse by the minute. After 45 minutes it won’t go faster than 50ish mph and it makes a very loud humming sound when it tries to shift. It has a harder time driving through cities than on the highway, my car just won’t go. I’m trying to gather the money to get it fixed but times have been hard so I haven’t even been able to drive the car. It only has 39k miles on it and I spent over 30k for it so it’s super agitating. I’ve talked to other Jeep owners and they’ve all complained about similar issues with the transmission.

1) 10/29/2020 I was driving on the highway with the cruse control on when the car made a loud thump, jumped out cruse control, shut off, check engine light came on. After sitting for a bit, car started but would not go over 25 mpr back to town. At the signal light, when stopped, the car started to go in reverse. Was able to stop it again, and got it to dealership. They said it needed a computer update. 2) 12/06/2020 1 month later, driving on the highway home from work at night, car did it again, check engine light came on. I was able to get the car to the side of the road. After sitting, it started, but would not run over 25 mpr. And this time at signal light stopped, the car surged forward and almost hit the car in front. The car is going back to the dealership ASAP. This car is very dangerous.
