2024 Chevrolet Colorado

Mid December 2025 my forward collision warning, adaptive cruise control, automatic emergency braking and auto high beams all stopped working. I combined the repair request with my next oil change Dec 22, 2025. The Chevy dealer, Serra, advised me that Chevrolet had no way to correct these problems, one of which was a $950 option. I have returned to the dealer more times, still no fix. I have talked to Chevrolet customer service, asked for a buy back, or car to drive till repairs and was denied. Chevrolet simply says just wait till we figure out how to fix our broken truck. I feel Serra Chevrolet has done all they can and has otherwise provided me with excellent service. Since the problems include safety features and I have waited over 4 months to date, I hope your agency can expedite the repair and secure some type of compensation for me.

Vehicle: 2023 Chevrolet Colorado Trail Boss Mileage: Approximately 14,000 miles I am submitting this complaint because the ABS braking system on my vehicle activates unexpectedly and causes a temporary loss of braking when driving over uneven pavement. When braking over potholes, bumps, or rough road surfaces at low to moderate speeds, the ABS system engages even though traction is available. When this happens, brake pressure is reduced to the point where the vehicle does not slow as expected. The ABS warning indicator flashes briefly, and there is a noticeable delay before normal braking resumes. This behavior has occurred multiple times in normal driving conditions on city streets, not during panic stops or slippery conditions. The issue feels most pronounced when approaching intersections or slowing in traffic over broken pavement, where consistent braking is critical. The momentary reduction in braking force significantly increases stopping distance and creates a safety concern. The vehicle has low mileage, has not been modified, and is maintained as delivered from the manufacturer. There are no warning lights remaining on after the event, and the issue appears to be related to ABS calibration rather than driver input or road conditions. This does not feel like normal ABS operation and gives the impression that braking is interrupted at the exact moment it is needed. Given the frequency and repeatability of the issue, I believe this represents a potential safety defect that could contribute to a collision, particularly in urban driving environments with uneven road surfaces. I am submitting this complaint to document the issue and to request that the ABS braking behavior on this vehicle be reviewed for safety.

ABS check engine light came on after initially taking the vehicle in because of the brakes feeling weird and making noise. This similar issue has been experience by multiple users reported on a Chevy Colorado group page on facebook to include 2 cases of individuals, one with a Colorado and another with a GNC Canyon, both GM vehicles, that had their brakes fail while operating the vehicles. This was a concerning issue because, in my case, while I drove the vehicle, I was able to punch the brake pedal all the way to the floor while the vehicle was slowing down. The vehicle and part were inspected about 3 different times with the final time, and with video proof of an odd noise it was making, which then caused the dealership service department to actually check the brake pump which then they found to be faulty and needed replacing. This also took about a month and a half of wait time because the part was on backorder. I also spoke to Chevrolet directly where they did not seem to be aware nor cared at the fact I explained to them many owners experienced this same issue and did not acknowledge my concern for safety of the vehicle itself.

The components failing are the (ADAS) components. Specific concerns are with adaptive cruise control, automatic emergency braking, front facing detection camera, and blindside detection. The front facing camera will randomly deactivate prompting a message to check for obstructions as a possibly reason of failure. Upon checking, and also wiping the lense, there is not obstrution. Blindside detection operates at random and at times will stay on for a sustained period without any vehicles near or around my vehicle. This is especially bad at night because the light is extremely bright and directed into the drivers vision. Adaptive cruise control will falsely detect vehicles or objects that are not present and implement emergency braking before recognizing there is no vehicle/object and then speed up. Sometimes this will happen consecutively in repetition. This is especially concerning because it has happened at interstate speeds as well as highway speeds with traffic behind me during the day time. It would brake aggressively taking my speed from 65 mph down to 40 mph and the change to a wide open throttle to regain speed only to brake again. Sometimes it will just keep slowing until I turn off cruise control. All of this happens without notice or indication other than the blindside warning lamps during its failure. It has happened often enough that I can not use the cruise control confidently. I have had it into the dealership for inspection and they claim there were no codes and could not reproduce the symptoms during a brief test drive. They however inform me that the front facing camera mentioned earlier does all the sensing for these components but did not get a reaction from it. I do experience one or more of these problems daily. I have also experienced false pedestrian warnings from the system early on but that has not happened for 3 months currently. I welcome requested inspection to hopefully get this fixed for my safety and those around me.

While driving in heavy and slow moving traffic at approximately 15 mph, the vehicle in front stopped. The forward collision and automatic emergency braking failed to activate. These safety features are not a replacement for active driving attention, but if they properly function and activate, they could have prevented the rear end collision that occurred.

forward collision alert system not warning when a near collision is about to occur. this failure was confirmed by the dealership. the dealership also told me they have 5 other 2024 colorados also failing with this area of the alert system. the dealership has tried 2 new cameras and the fault continues. chevrolet care team knows of the failure, but have given no updates on how to correct this.

1) All the sensors on the truck relating to the auto emergency breaking, pass sensors, cruise control ETC are malfunctioning, truck was at 10,000 miles at the time and brand new. 2) This feature contributed to an accident on Jan 14 2025. I could not see because of the sun and rear ended the car in front of me. 3)The DTC report on the truck came back and stated 6 errors relating to the systems and sensors to include a data memory loss. 4)Took in for servicing at the dealership and they refused to touch the issue. GM is inspecting the truck Feb 13. 5) There were warning indicators however I though it had to do with ice blockage from a snow storm. That morning I cleaned all the cameras off and did not immediately notice it and assumed it went away. It seems the the warning does not immediately come on takes approximately 1-2 minutes. There is no differentiating a software-servicing issue with a camera blockage.
