Warnings problems of the 2017 Toyota Highlander

Customer support program ;; zjc. . . . Toyota has received reports about potential symptoms, such as a whine noise from the transmission while driving, harsh shifting, reduced power, , in the subject vehicles that are equipped with a model ua80 transmission. There is a possibility that a washer tab, designed to prevent the loosening of a nut inside the affected transmissions, was not sufficiently bent during assembly. This could lead to the nut loosening and, over time, lead to the symptoms described above. I. Ve been having this issue with my transmission for a couple of years. My issue started ,when I first got this Highlander back in 2017 . When coming to a stop ,I would get a thumping sound from tranny . I took this SUV to dealer ,twice for said tranny issue and pre collision system not functioning properly was told nothing wrong! this happened while SUV was still under warranty! I eventually need to replace front windscreen : after which pre collision was functioning properly this was done by safelite autoglass! a couple of months the tranny had a new issue ,tranny began to hesitate. A few months went by and then another new symptom developed ,I was getting shuttering at 1400 rpm ,which goy worst if you were at this rpm for a little while. I've been sick for a couple of years now and was not able to take to dealer to diagnose issues associated with tranny. I've kept driving my Highlander with these issues ,since it started!! customer support program zjc addresses some of the issues I have with my transmission. I don't know why my transmission and VIN# is not included in this program. . I'm worried if I went to doctors appt and Highlander broke down ,what I'm going to do. . I'm on social security disability ,I cant afford much !.
