At 10,000km my 2017 T120 Black suffered a malfunction of the gear changing assembly. This was fixed in April of 2020. In early May of 2020, I had an incident where the bike and I fell over on the left side, this was not on a public road, or traffic-related and the drop was what I would have considered minor. Fast forward a month and a half (as well as over 1000km) later, and my bike is back in to shop on June 30th, 2020 at 12,250km because again, the bike will not shift down through gears, only up. Me being a shmuck, I tell the shop I dropped it a month ago, and it's probably my fault and so I pay the bill of $528 dollars out of my own pocket.
Here I am again.
There has been no further incident to this motorcycle, on April 13 2021 I found myself unable to shift gears again. This occurred at 18,000km ONLY 5500 since the last repair. In 2019 Triumph updated the Gear Shaft Assembly, it's a Service bulletin that can be found here.

Can be found under the power train section.
This document to me recognizes that changes had to be made to this part but neither accepts responsibility or acknowledges that this is a chronic problem facing their new water-cooled engines. They have attempted to keep the issue quiet, allowing consumers such as myself, and loyal dealerships to shoulder many or all of the costs associated with this fault. I no longer have faith in the company's products, My crankshaft balancer was repaired under warranty due to improper installation at the factory, and hilariously enough, my headlight also came installed upside down. The only positive experience I have had regarding this bike is that the dealership I purchased it from has been amazing, and have offered to cover half the labour cost of this repair as Triumph is only willing to "Good Will" the part. The part which undoubtedly, will likely fail again.
Should change their name to the Triumph Lemon Company.
