2024 Chevrolet Colorado

Visibly observed antifreeze / coolant leaking from top radiator hose where it connects to the radiator. Dealer replaced upper radiator o-ring but it's still leaking. At 17000 miles a service brake warning message showed up on information screen. Front brake rotors are warped. Dealer states normal wear on front brakes. Also the dealership stated the front left inner brake pad was down to 2mm of pad left. Wanted over $420 to turn rotors and replace pads. I inquired why the left front pads were worn so much than the right side. They stated this was normal!

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.

At engine start up there were two warnings that came up on info screen. "Service Front Brake Monitor" and "Front Brake Pads Low". Just before this incident the monitor showed front pads at 82% brake life and the rear pads at 84%. Upon my own inspection the driver side front brake pads are worn significantly more than the passenger side. Front brakes are also squealing when coming to a stop. Chevrolet dealership inspection/repair scheduled for 9/22/25.

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.

We purchased a used 2024 Chevy Colorado WT with a little over 4,500 miles on April 9th. A couple of days later before starting the vehicle the brake pedal would sink all the way down to the floor. This happened twice. So I made a service appointment with the Chevy dealer on April 14th. I told the service advisor that the brake pedal sank to the floor twice before starting the vehicle. He said they would take a look at it. When I went to pick up my vehicle the next day, the service advisor said the technician could not duplicate the problem. That same day, the brake pedal sank to the floor before starting the vehicle. So I made another service appointment the following week on April 23rd. I have videos to prove that the brake pedal would sink all the way to the floor before starting the vehicle. The service advisor told me that that technician duplicated the problem and they will order parts for it. The vehicle has been at the dealer since then.The service brake issue is a safety hazard that needs to be addressed.

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.

I purchaced a new 2024 Chevy colorado, the truck had 193 miles on the odometer when the brakes failed. When I stepped on the brake to put my truck into gear the pedal became spongy and brakes were severely diminished. I had to force the pedal to the floor to stop the truck at idle. I shut the truck off and restarted, it continued. I called the dealer, they sent a truck with trailer to take it back to the shop. They verified the condition and diagnosed the problem. I was told the EBC and master cylinder failed. The warning on the dash came on at the same time as I realized the brakes were not working.

I have had this truck for about 3 weeks and the first day I brought it home the Parking brake was engaged upon starting the truck along with the collision light. It finally came off and drove the truck. Took it to the dealer they checked it and said it was fine per their assessment. Couple days later it happened again took back to dealer as the collision and parking brake light and brakes were stuck again, they again ran their computer diagnostic system no issues. Drove it for about 3 days and now it occurred again today, collision light and parking brake engaged. After about 15 minutes of trying to disengage the parking brake I shut the truck off, then one last time I started it back up and the brake disengaged. I then drove it back to the dealer today.
