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.

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.

The windshield cowl and trim pieces keel breaking. If I didn't keep an eye on them they would just end up flying off causing road debris or projectiles

While driving home multiple lights,messages and sounds came on the dashboard. I stepped on the brake and there were no brakes. I put vehicle in neutral and pumped brakes a few times. I was not traveling that fast so the vehicle stopped before I hit the person in front of me. I drove 10 mpg with my hazards on to the nearest gas station. I called Chevy service and they sent a tow truck N/C to bring to the dealer.

I was told that my vehicle has a bent exhaust valve, which has caused irreparable damage to the engine and requires a complete engine replacement. The dealership could not determine what caused the valve to bend, but they indicated that it could potentially be a manufacturing defect, although they could not confirm that. My vehicle has now been at the Chevy dealership for more than 30 days, and I was informed that there are currently no replacement engines available from the factory due to a shortage. Given that this appears to be a known parts shortage, I assume other owners of the same make and model may be experiencing similar issues, although I cannot confirm that. The vehicle has approximately 10,000 miles on it.

Was on a trip and on the highway home the service break lights came on. By the time we got home(less than 200 miles) the breaks where scraping the calipers. Truck only had 25,586 miles on it when they picked it up to take to the shop. Dealership had to replace the break pads, calipers and rotor on the front driver side.

I purchased this truck new in March of 2024, in May I was at a Starbucks drive-thru and lost all brakes. While slowing down at the window the pedal went to the floor and my dash light up like a Christmas tree. I pulled into a parking spot and shut the truck off for about 5 minutes. When I turned the truck back on the lights were gone and the truck seemed fine, so I drove home. The next day I was picking up my kids from school when in the pickup line the same issue happened. I lost my brakes, the dash lit up, and the truck started rolling forward in the pickup line. I had to push on the brake pedal as hard as I could to make the truck stop. I called the dealer and had the truck taken there. The truck was there for several days and I was told the master cylinder and brake control module were replaced. I’m reporting this now, because I saw that this is part of a larger issue being reported and I wanted my experience memorialized to help others.
