2015 Chevrolet Colorado steering problems

“Power steering Assist is failing consistently. Travelling on highways 65+ speeds while the power assist goes out. Must make it to the side of the road to reset vehicle. No they have not been able to reproduce because they do not test it long enough. By a Chevrolet dealer twice now. First visit they simply replaced the battery and never informed me of error codes regarding this internal component being a problem No warnings until the power steering goes out. There have been recalls from GM for power steering errors but they will not fix this one.”

“Vehicle experienced sudden loss of electronic power steering assist due to an integrated EPS module failure. This matches the exact failure criteria of GM Recall N202325410, but my VIN was excluded due to manufacturing date limits.”

“The contact owns a 2015 Chevrolet Colorado. The contact stated that while driving and making a left or right turn, the steering wheel shook abnormally, and the failure ceased once the steering wheel returned to center. The vehicle was taken to an independent mechanic, where the tires were replaced and the front alignment was inspected; however, the failure persisted. The contact was referred to the dealer, who was contacted by phone and confirmed that the VIN was not included in NHTSA Campaign Number: 21V213000 (Steering). The failure mileage was approximately 75,000.”

“Shortly after startup or while driving, my vehicle will suddenly lose power steering. The dashboard will illuminate the traction control light and warn "Service Staiblitrak" and "Power Steering Reduced Drive With Care" however this happens when the power steering is already lost. This has happened while pulling out of parking lots and also while pulling up to a red light in the street. If I turn the vehicle off and on 1-2 times then the fault clears and I can continue driving. A dealer could not reproduce the issue. They found two stored fault codes but could not diagnose further. There is no advance warning of the failure. The failure is random and has occurred about 2-3x per month for 3 months.”

“While driving my vehicle, the power steering assist suddenly and completely dropped out without warning. The dashboard displayed the warning message 'Service Power Steering, Drive with Care'. Immediately, the steering wheel became extremely heavy and nearly impossible to turn, creating an immediate and severe crash hazard. Turning the vehicle off and back on temporarily clears the message, but the power steering assist fails again shortly after. This is an intermittent hardware and electrical communication failure that makes the vehicle unsafe to operate on public roads. I contacted a Chevrolet dealership to check for remedy under NHTSA Safety Recall #21V213 (GM Recall #N202325410). However, I was informed that my VIN is not included in the current recall list, despite my vehicle experiencing the exact same catastrophic steering gear and torque sensor defect described in the recall. I am filing this report because this severe safety defect clearly extends beyond the manufacturer's limited VIN scope.”

“The Electric Power Steering (EPS) system suddenly and completely malfunctions, causing an abrupt loss of power steering assist. The power steering assist cuts out unexpectedly while driving, making the steering wheel suddenly violent and extraordinarily heavy to turn. This creates an immediate risk of a crash, as navigating curves, intersections, or avoiding obstacles becomes nearly impossible without immense physical exertion.Has the problem been reproduced or confirmed by a dealer or independent service center?No, a dealer has not confirmed it yet. Because the defect is highly sporadic, it has been difficult to time a service visit with the exact moment of failure.Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others?No, it has not yet been inspected by any of these entities.Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear?When the failure occurs, a "Service Power Steering" message immediately appears on the dashboard alongside an audible warning chime. There are no advanced symptoms prior to the sudden failure. The issue is…”
