Known issues on the 2015 Colorado. Seven recalls sit on the federal record for this model year. Two involve the electric power steering, where a poor connection inside the steering gear can reduce or remove assist while the truck is moving. Another covers front brake calipers that can leak fluid through a flaw in the casting, lengthening stopping distance. A third covers seat frame hooks that were not properly attached, so a seat may not stay anchored in a crash. Steering dominates the 489 complaints with 356, ahead of 41 on the power train and 20 on the electrical system.
