The 2016 Colorado is the loudest single model-year in this nameplate by a wide margin, and the reason is not the transmission everyone associates with these trucks — the eight-speed did not arrive until 2017. It is the steering. Owners describe the electric power steering assist cutting out mid-drive with no warning, usually announced by a StabiliTrak or traction-control message, sometimes cleared by shutting the truck off and restarting, and eventually not cleared by anything. Several report it happening four or more times. One writes that he cannot let family members drive the truck because they are not strong enough to turn the wheel when it fails.
What makes this a walk-away rather than a caution is the coverage picture. GM recalled the 2015 Colorado for exactly this — a poor electrical connection in the steering gear causing loss of power steering assist — under campaign 16V054, then NHTSA opened a formal Recall Query into whether that campaign was broad enough, and GM issued a second campaign, 21V213, covering 60,681 trucks. Both are model year 2015 only. The 2016 owner pays for the steering gear. Unless the truck in front of you has a documented steering gear replacement and a test drive long enough to provoke the fault, there is a better Colorado two model years down the road.
