NHTSA Complaint #11686637 — 2018 TOYOTA C-HR

At approx 110K miles, I noticed the CVT transmission whining during acceleration - w/ the whining noise increasing/decreasing as I accelerated/decelerated. As the whining increased over the ensuing miles, during my 120K service, I asked the dealer to evaluate its cause - and was advised that my transmission is failing and that I need a new one. Estimated cost: $12K. Yes, trans is available for inspection upon request. Obviously, should the trans fail while the vehicle's being operated, it could leave the driver (me) stranded or worse. Trans has only been evaluated by the dealer's service tech(s). No warning lamps or other indicia that trans is failing has appeared. In addition, I've noticed no performance issues/differences - w/ the only symptom to this point being the loud whining as I accelerate.
