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.

The steering shaft on my 2026 Colorado Trail Boss is faulty and needs to be replaced. There was no accident but feel like this could be a safety issue that needs to be addressed and reported.
