NHTSA Complaint #11614078 — 2015 CHEVROLET COLORADO

While driving at highway speeds, our 2015 Chevrolet Colorado suddenly experienced loss of power assisted steering. I was able to steer the vehicle, but there was no power assist. This happened suddenly, with no advance warning lights. At the time of the incident, the driver information center displayed "check power steering". The sudden loss surprised me and although the vehicle was driveable, the steering was very difficult and a large amount of effort was required to park the truck. I am very glad this did not happen while my wife was driving the vehicle. Upon restarting the truck after a key off cycle, the code and the symptom disappeared. We were able to drive the truck home without the failure occurring, only to drive it again the next day and experience the failure a second time. Once again, the symptom disappeared after a key cycle. We researched the issue on line and found a recall N202325410 that described the same issue that we experienced. However, our trucks VIN is not included in the recall. This is disturbing to me, because our truck displayed the exact symptoms described in the recall. I repaired the truck using the GM approved recall repair procedure, which was to replace the steering torque sensor cover. We have safely driven the truck with no further loss of the power assist for 2 weeks. If we had known this could be an issue, we would have addressed it pro-actively. Instead, we experienced a failure on the highway. I am relieved that no accident occurred, but any number of circumstances could have occurred that lead to an accident when you suddenly loose your power assist on steering. The vehicle is available for inspection, and I have saved the torque sensor cover that I removed. My local dealer confirmed the failure and provided information on the recall. My vehicle has not been inspected by GM, the police, insurance representatives, or others besides my GM dealer and myself. Warning lamps as described above.
