Consumer Reports projects that the Silverado and Colorado are going to be troublesome.

Consumer Reports (CR) has just released its latest ranking of the vehicles its data point to as troublesome. CR’s surveys take a deep dive into the numerous things that can go wrong with a vehicle. The group studies 17 trouble areas, from nuisances—such as squeaky brakes and broken interior trim—to major bummers, such as out-of-warranty transmission repairs and trouble with four-wheel-drive systems. The CR team then weighs the severity of each type of problem to create a predicted reliability score for each vehicle. To be considered for this CR list, the group must have at least two model years of data in calculating the predicted reliability score.
