AutoNation Chrysler Jeep Broadway

My 4xe has not been charging and the check engine light has been on and off since may of last year. I’ve owned the vehicle for 12 months and 6 of which the electric feature doesn’t work so I’ve been in and out of service. As of today it still is not functional and the check engine light is back on. I was told it has to be my fault and my homes power. I paid an electrician $270 to come evaluate my home and power and everything is good on my end. I think they can’t figure iut what is wrong w the vehicle so sending me home the problem and telling me it has to be my fault is the only solution. I am not sure what to do at this point w the car. I’m a single mom that works 60 plus hours a week that can’t be without a car and bought this jeep to save money on gas not be in a service bay. Oh and on top of all of that my rim was scratched while in service with them for several weeks and they still haven’t determined how to handle that.
