Vehicle: 2026 Chevrolet Colorado Trail Boss, 4WD Crew Cab. Delivered new 3/29/26. Beginning in May 2026, the vehicle developed a steering column defect: play in the steering wheel, a catch or jerking sensation while driving and turning (particularly at low speeds and on rougher residential/city roads), a structural popping noise, and an accompanying dashboard rattle. Dealership staff advised the vehicle was safe to drive despite the confirmed defect, and I continued operating the vehicle with my family for approximately two months while a replacement part was on backorder. The vehicle has been repaired three times for this identical defect: - 5/5/26–7/3/26: intermediate steering shaft replaced; defect returned - 8/17/26: upper and lower intermediate steering shaft joints replaced; defect returned - 9/7/26–10/7/26: intermediate steering shaft replaced again. Dealership staff told me directly this repair was untested and that I would be the first to determine whether it holds up long term. The repair order's own mileage log shows only 18 total miles driven for the entire 30-day visit, including the post-repair verification test drive. No independent manufacturer field inspection was conducted before the vehicle was released back to me. Since picking up the vehicle on 10/7/26, I have noticed new symptoms: the vehicle occasionally pulls to the left when braking, and the steering feels unusually tight at times, as though the power steering is not fully engaging. A loaner vehicle (also a Chevrolet Colorado) provided to me by the dealership during an earlier repair exhibited the identical steering catch and popping symptoms as my own vehicle, suggesting this may be a defect affecting the platform rather than an isolated issue with my individual vehicle. I am filing this report due to the ongoing safety implications of a recurring, unresolved steering defect on a new vehicle, the manufacturer's acknowledgment that the most recent repair was unverified, and new symptoms

Incident May 5, 2026

The contact owns a 2026 Chevrolet Colorado. The contact stated that while driving approximately 45 MPH and approaching a traffic light, the contact heard a loud popping sound, and the sunroof suddenly shattered. The sunshade was closed at the time of the failure. The contact stated that glass started blowing from the sunroof. The sunroof glass was shattered in a mushroom-shaped pattern and was fractured outward. The contact purchased plastic from a hardware store to temporarily cover the opening. The vehicle was taken to a local Chevrolet dealer, where the dealer was verifying the warranty coverage. The vehicle was scheduled to be repaired. The failure mileage was approximately 500.

Incident Oct 1, 2026

The vehicle developed a rapid and moderate shudder followed by "Check Engine", "Service Traction Control", "Service ESC" messages and associated icons on the driver display. The shudder happened a second time within approximately 30 seconds and the engine lost power followed by "Reduced Power Warning" message. I engaged the emergency flashers and limped to the nearest side road. I had to stop on the road because of no shoulder. I waited there while assessing the situation and eventually was able to drive the short distance home. I disconnected the battery to reset the PCM. This action temporarily cleared the fault code and check engine light. The first dealer said it couldn't do anything without a fault code. A second dealer said it was unable to duplicate the malfunction. Two weeks later the vehicle began to shudder on a busy interstate, with the same warning lights and messages and had to pull off the interstate. It happened once more on the way home. The dealer duplicated the issue. It took them over 30 days with multiple repair attempts. The dealer replaced all four fuel injectors, fuel injector wiring harness, Engine Control Module (ECM), and wiring between the ECM and another connector. The dealer had to reach out to GM's Technical Assistance Team (TAC) to get it back on the road again. Approximately 8 weeks later, the vehicle began to shudder again, this time only while travelling up hills. There has not been any messages or warning lights associated with this event. The vehicle was taken back to the dealer where is has been now for almost a week with no follow-up on the diagnosis or repair status. These events compromised safety and we were put at risk due to the sudden lack of power while in traffic, maintaining control of the vehicle while trying to understand the situation, and the possibility of other drivers adversely reacting to these events.
