If by interesting you mean the Colorado is not mentioned at all then we're on the same page.
Non-vehicle model specific awards are meaningless, and those that are specific really have to be scrutinized. A quick search of the JD Powers website for
Chevrolet for the Colorado for 2016-19 (2020 has nothing yet) don't show the Colorado at all. Click on the link, pick your year, drill down through things. It probably would not hurt do do more research on J.D. Powers - that is interesting.
I can tell you that I have had worrisome issues with my 2017 Colorado diesel and question the long-term reliability of both the engine and transmission (6 speed). I've had the ECU replaced, some wire chaffing issues checked, and had to update the headlights which have remained rated
poor per the IIHS fo
r the entire run to date which is astounding as this is a safety issue, and Consumer Reports gives the predicted reliability rating a whopping 1/5 (subscription, cannot link to that).
