2026 Chevrolet Colorado

On April 11, 2024, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE24011 after receiving complaints concerning a loss of brake assist in 2023 MY Cadillac Lyriq vehicles. These complaints allege a hard brake pedal, followed by a “Brake System Failure” message at start up or while driving. GM shared records regarding several internal investigations for loss of brake assist due to alleged spindle fractures in the eBoost system. GM has stated that in the event of a spindle fracture, anti-lock brakes (ABS), stability control, and traction control remain functional until the vehicle comes to a complete stop. At this point, ABS, brake assist, stability control, and traction control functions are lost. The loss of these functions causes the vehicle to set one of three Diagnostic Trouble Codes (DTCs) based on failed performance criteria for the Electronic Brake Control Module (EBCM). These DTCs, in turn, activate several driver alerts: an audible chime, a visual “Service Brake System” message in the display, and multiple illuminated Malfunction Indicator Lights (MILs) for the ABS, Traction Control, and Brakes informing the driver of loss of functionality. The vehicle speed will also be limited to 70 KPH (43 MPH). Since opening PE24011, ODI has continued to receive reports of loss of brake assist. Some of these reports describe symptoms inconsistent with GM’s description of a spindle failure. These reports allege an immediate loss of brake assist functionality as opposed to the loss occurring after the vehicle comes to a complete stop. The sudden loss of brake assist during a braking event could result in extended braking distance, which increases the risk of a crash or injury. ODI believes further analysis is necessary to assess the potential for failures in GM’s eBoost system to resulting in safety-related outcomes. At this time, ODI is aware of the following vehicles that are equipped with this eBoost system: 2023-2026 MY Cadillac Lyriq, Chevrolet Colorado, and GMC Canyon; 2024-2026 MY Buick Enclave, Envision; Chevrolet Blazer EV, Equinox EV, Traverse; Cruise Origin; and GMC Acadia; 2025-2026 MY Cadillac Celestiq and Optiq. ODI is also aware of 2024-2026 MY Acura ZDX and 2024-2026 MY Honda Prologue vehicles that were built with this system. The Acura and Honda vehicles were manufactured by GM in a joint venture with Honda, and will be included in the Engineering Analysis as peer vehicles. ODI is opening this Engineering Analysis to further assess the safety-related consequences of a failed eBoost system. In addition, ODI is expanding the scope of the investigation to encompass all GM vehicles that share this eBoost system.

My truck makes a very loud horrible noise when the fuel pump primes after the truck sits for a few hours it’s a clear flaw with the fuel pump and I’ve seen multiple people complain about this issue and there’s no fix for it.

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.

The contact owns a 2026 Chevrolet Colorado. The contact stated that when the vehicle was purchased, the passenger’s side air bag warning light remained illuminated. The vehicle was taken for tire maintenance, and the contact was informed that the air bag warning light should not be constantly illuminated. The dealer was contacted about the failure. The dealer diagnosed a failure with the restraint system and that the sensor on the passenger’s side was not operating properly, causing a failure with the passenger’s side air bags and seat belt. The contact stated that the part to repair the vehicle was no back order. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 5,952.

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.

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.
