I did a custom build on a 2023 Colorado Trail Boss. Two weeks after picking it up it started having electrical issues, the dynamic cruise would suddenly brake for no reason, blind spot monitors would light up with no vehicles around, front collision sensor would turn off, screen would freeze. Now at 48K the trans slips between 3rd and 4th then slams into gear. Only when it's cold and the colder it is outside the worse it does it. Once it warms up its fine. The dealer looked at and said they couldn't find any problems. They did a module reprogram and flush but it still does it. They have done multiple software updates for the electrical problems but they always come back a short time later. Being that I did a custom build it's really disappointing because other than these issues I really like the truck.
