NHTSA Complaint #11620170 — 2019 FORD EDGE

My cars rpm's started randomly jumping which would coincide with a slight jerking feeling when the car shifted gears. First I was told it was my spark plugs and then the coil packs. When both of those were changed and the problem persisted they ran multiple diagnostic tests and came up with nothing. Then my car started to shudder when I put gas in it and then the radio screen and door locks would intermittently stop working and again they found no error codes. Then my pre-collision warning system started going off when there are no cars even remotely near. The same for my blind spot indicators. They just go off for no reason. Now after months of issues and zero error codes, they say it's the transmission failing and it will cost me $6,000 to fix. That's assuming that is actually the problem.
