I own a 2015 Colorado and a 2016 Traverse. Both bought used with under 20,000 miles. I just had the Colorado in for major service issues. At 54,500 miles I should not have a problem with a faulty power steering gear (cost to replace $1665.78) and a faulty torque converter (covered under warranty). I have not owned Chevy vehicles for many years and may not again if this type of pattern is common?...
