I would like to hear from more owners who have had power steering issues with either a 2015 or 2016 Canyon or Colorado. This is an important issue that owners need to aware can happen amd what the symptoms/results can be
Symptoms almost implies a forewarning - in my case, there was no warning. First time it happened, I was driving out of a business driveway, came to end of driveway, pointed straight, and the DIC lights up. I look at message, as I pull away, and realize as I go to left turn onto the road I have no power steering.
Pretty much everytime my failure occurred I was headed straight, cannot think of a time I was in the middle of a turn. So the description of one driver that his vehicle snapped back straight I never saw, but at same time, I find this to be a bit odd- I do think it would begin to go back to a straight mode, but not just snap back straight.
Mine felt fine until the first time the messages came up. After shutting down and restarting it felt very light; almost over-boosted. Then the messages came up again and then it just felt like an old car without power steering. Once I was ready for it I didn't feel in any danger or anything.
My biggest issue was that the problem was so intermittent that I was nver "ready for it" to occur. Sometimes it occurred 2-3 times within a few miles, sometimes it was days between failures. I have driven everything from compact cars to 3 ton trucks, forklifts, heavy equipment, etc. I would probably be considered an aggressive driver. As such, I have to be prepared for a failure of the mechanical systems, so I handle these things fairly well. My wife is not adept at such things and was scared to drive the truck until we got the repairs.
Note: After the system was replaced, I have driven over 32K miles without another issue.
I think there may be at least 3 different steering issues that have been seen on the trucks:
1. Total failure of both power steering and stabilitrak, intermittent, like I saw. Corrected by total replacement of steering rack.
2. Death wobble or some other sort of issue where steering becomes unstable, vibration in steering wheel, etc., corrected by reprogramming the steering control module.
3. Some other "total" failure of steering that occurs that only effects steering, not sure I have a clear understanding from the descriptions here.
