2024 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. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

The contact owns a 2024 Chevrolet Colorado. After starting the vehicle, the engine ran for several seconds before the vehicle unexpectedly shut off. The check engine warning light illuminated, and the word "Key Fob" was displayed while the key fob was in the contact's hand. The vehicle failed to restart and made a clicking sound. An independent mechanic diagnosed the vehicle with fuel pump module failure. The fuel pump module was removed and cleaned; however, the failure reoccurred four months later. The contact purchased a new fuel pump module and the mechanic installed the part. The manufacturer was notified of the failure by phone. The failure mileage was approximately 22,000.

In July 2026, I received a message on my truck's dashboard to "Service Latch System". Neither of my passenger doors would lock. I brought it into the Hendrick Chevrolet Service center, and they told me the actuators on both passenger side doors failed. Even though the truck is only 2 years old, they said I was past the mileage on the 3-year warranty and I would need to pay out of pocket for replacing the actuators. They replaced them. Then this week, week of September 21, 2026, the driver side door locks stopped working. They are now telling me the actuators on that side have now failed and I need to pay out of pocket for it again. I am concerned there is an underlying defect in the vehicle not being addressed.

Love my 2024 Chevy Colorado and researched every aspect about it prior to purchase....accept the REQUIRED Onstar subscription to enable the handsfree "speaker button" @ RH side of steering wheel for phone, navigation, etc. I was finally made aware of a promotional that came w/ the truck by an Onstar rep that only worked for one month, which no one @ the dealer, sales rep, finance, etc told me about. Once function quits, using an Android phone, it is impossible to utilize, requiring physically handling the phone to initiate and end calls.....which is unsafe and illegal in my state. It is aggravating to me that one should have to pay 45.00 a month for a great feature that is factory installed on the steering wheel when my 2015 Ford worked for free for the entire time I owned it. As a safety item it should be free and could lead to issues for others if they opt out...distraction BAD

I bought this vehicle late June 2026 and it is currently September 1 2026 and last week I encountered a check engine light. Its already having coolant issues. Way too early for something like this. Only 64,000 miles.

Engine cooling system has a known leak. It is rather expensive out of pocket and although there is now a tsb the tsb does not cover the danger of overheating an engine and being stranded on the side of the road. Also the coolant leaking causes an unseen hazard by polluting water supplies with one of the more known toxins to the water and environment.
