NHTSA Complaint #11557088 — 2017 NISSAN PATHFINDER

I am told my transmission needs to be replaced and I need timing chain repair kit. I had transmission service in June 2023 and our car started with a funny noise. Had oil changed and tune up and still same sound Car started to jerk really hard on accelaration after 25mpg then would catch itself up and then loose power. I took to back to place that did my transmission service and they deemed 2 parts in my transmission went out. I have only driven my car for 54585 miles. When I got it it had 48583. I have not driven the car 100000 miles ourselves and this happens. I argued with them because Ihad no problems with my car, we were trying to follow the guidlelines of service for mileage. Now we are stuck with no car and the cost of repair 10,500 that we do not have plus having a high car payment. I asked when purchasing the car about the transmission because of things I had heard but the sales guy reasured us they have fixed the problems with the CVT engines. Not true thats why with the new models they went back to the standard transmission. WE NEED HELP!!!!
