NHTSA Complaint #11610434 — 2016 FORD EXPLORER

My car started shaking while i stopped (like at a red light, stop or traffic) I had it diagnosed ($175) and was told it needed to have the transmission changed, my explorer was 6 yrs old with less than 50k miles. I have never hear of that happening as the car well kept. New transmission cost me $5585.40, it seems that every year this car has a new problem. I feel so ripped off this shouldn't happen on a $50k car.
