The contact owns a 2026 Chevrolet Colorado. The contact stated that while driving 70 MPH with the adaptive cruise control engaged, while the vehicle was approaching another vehicle from the rear, the brakes independently activated. No warning light was illuminated. A dealer was contacted. The vehicle was taken to the dealer to be diagnosed, and the contact was advised to stop using the adaptive cruise control while driving. The vehicle was not repaired. The manufacturer was notified of the failure and opened a case. The approximate failure mileage was 8,664.

Not sure if this is a safety issue at this point but there is a rattling noise around the steering column when you drive over any bumps and hoping this will not lead to any safety issues.

Component: Drivetrain, brake, and engine management systems repeatedly fail in a coordinated pattern, with multiple warning indicators activating simultaneously and sudden unintended deceleration occurring without warning. Vehicle available for inspection. Safety risk: Most recent failure occurred at highway speed with family including passengers in the vehicle. Without warning, the vehicle decelerated abruptly while multiple dashboard warnings activated at once. Sudden deceleration at highway speed creates immediate risk of rear-end collision from following traffic and loss of vehicle control. Prior dealer confirmation: Yes. Curry Chevrolet (Scarsdale, NY) has had the vehicle in service for the same defect category on multiple prior occasions, including stays of over a week on at least two visits. The dealer has not permanently resolved the issue — symptoms have now recurred at sixth time. An additional early service visit at the same dealer was not documented with a repair order; I retain contemporaneous text messages establishing that visit occurred. Other inspections: Inspected only by Curry Chevrolet to date. GM Customer Assistance engaged (Case #XXX). No police, insurance, or independent inspections. New case has been filed with GM, linked to the previous (Case #XXX).Next service visit will be at a different authorized Chevrolet dealer for an independent diagnostic. Warning indicators: Yes. In the most recent incident, multiple warning lamps and system alerts activated simultaneously at the moment of deceleration, with no advance warning. Prior incidents showed the same multi-system warning pattern, consistently without predictive indicators. Vehicle is a 2026 Chevrolet Colorado, VIN [XXX], delivered January 2026 with 2,209 miles on the odometer at delivery.

Front passenger headlight assembly is defective with less than 200 miles on vehicle. The defect is allowing excessive condensation in assembly and fogging up headlight brightness and assuming will eventually cause bulbs to prematurely burn out. This in my opinion is a safety concern and issue . Also seems like there is a shortage of the defective headlight assembly.
