Many improvements and updates? Of course there could be new model problems as well, although it's been out for a while now globally. Only you can justify if you should consider a new one or not but you like the one you have and it's working for you so unless you want the new features and a new truck probably not.
But for some looking at a new mid-size truck, and like Ford, they might be interested in the all new Ranger.
Some like to change every few years for the latest tech improvements, interior layout, suspension tweaks, whatever.
Some like to change with every generation and the current generation is essentially 10 years old now.
Others may not always like new, if it's working ok why change? I can be like this. For instance I traded a 2018 Ridgeline on a (same generation) 2023 model just because I was concerned that Honda may screw the next generation up more than improve it, in particular the transmission and 3.5 V6.
Anyway the thread is titled "New Ranger Review", the current version is about to cease production with the next generation Ranger starting production by early Summer.
