2024 CHEVROLET COLORADO Service Brakes Problems

The front brake pads are showing extremely uneven ware. Outer brake pad is at 2mm and the inner is at 7mm due to a spring issue on the front caliper. There is also a lip on the left rotor. The tech used 25-NA-365 to help identify the issue. However, my VIN is not covered under this repair. The result is a $500 out of pocket repair for something that should be a mfg defect and not wear and tear. As this was already outlined as an issue with other 2024 Chevy Colorado's I am asking this to be expanded to cover my vehicle as well. The issues was also causing my brake sensors to "detect" new brakes and I had to inform the vehicle that I have not had brake service done to trigger this alert.

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.

I have had 3 separate occasions where the automatic emergency braking has engaged with nothing in front to trigger it. Each time was one a busy section of road, two of those times I had traffic behind me nearly causing an accident.

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.

Started the truck and got a Brake System Failure, Service ESC, Service Trailer Brake System, Traction Control, Forward Colission, ABS, Check Engine Light and Parking Brake Warning light flasing. Also the Auto Start Feature works less than 10% of the time.

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.

On the afternoon of [XXX], I had an interesting incident in a parking lot while slowly pulling into a parking spot. As I began braking, the brake pedal suddenly sank to the floor, forcing me to engage the emergency brake to stop the vehicle. After restarting the truck, the pedal firmness returned, but I noticed a peculiar sound, likely originating from the ABS pump or solenoids. No warning lights illuminated on the dashboard, and no error codes were detected with my scanner. Additionally, I’ve observed that the front driver’s side wheel has significantly more brake dust compared to the passenger side. I brought this issue to the attention of the service advisor at Boulevard GMC in Signal Hill, CA. Boulevard GMC informed me that brake parts are currently on a nationwide backorder, and there is no estimated time of arrival for when GM will supply dealerships with replacement parts. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Got notification of brake system failure on the dashboard and lost all braking ability. After the truck was shut off they worked again, perfectly fine. This scenario repeated itself and I lost breaks again. The truck has 200 miles on it and after looking online seems to be a common issue

We purchased a 2024 Chevy Colorado mid June and drove it successfully, without incident until the end of August when the vehicle had complete brake failure. My husband was driving on I-95 in morning rush hour traffic when the dashboard lit up flashing several different indicators and a message saying "Brake System Failure" and "Service ESC" He had no brakes but could slow somewhat by applying as much pressure as he could to the brake pedal. He got the car to the dealer that same morning, Grieco Cheverolet Delray. They worked on the car all day and we were called in the late afternoon to pick up. It was explained to us that GM advised their mechanics to restart the computer that controls that component and that the problem should be fixed. We were also told they were going to go ahead and order a replacement part in case "it happened again." This comment did not leave us with much confidence. Then, as we were checking out, the employee noticed there was no explanation of what had been done to the vehicle. He called the mechanic and said he refused to hand over the keys until notes were added explaining what was done to address this serious issue. So notes were made, copies were handed over, and off we went. The truck drove perfectly until exactly one week later when the dash lit up again with all kinds of alerts and lights stating, "Brake System Failure" and "Service ESC." That's right, no brakes again. We had the truck towed back to the dealer this time and we have been told they have ordered "the part" and it will probably be 3 weeks. That was one week ago and we have not heard anything yet. We have concerns over how nonchalant Cheverolet and the dealer seem to be about a brand new car having complete brake failure twice and no real explanation as to why. Can you advise? Thank you

Component/system issue: Intermittent loss of power assist to brakes after auto start-stop startup. Safety Risk: Unable to use brakes normally. Requires hard brake pedal pumping to get vehicle to stop. Reproduced by others: No. Doesn't happen every time. It has happened a total of three times (so far). Inspected by manufacturer: Yes. The first time, the dealer found low voltage DTC set. Replaced battery. Second time, dealer found low voltage DTC (P 0562) set. They contacted GM TAC who provided a file to patch the radio software. Third time, other (possibly related) electronics issues were also present which caused the vehicle to enter limp mode every time it's driven. They've replaced the ECU and the accelerator pedal, neither of which fixed that issue. They are now awaiting a wiring harness from GM to see if that is the root cause. Hopefully it also fixes the intermittent loss of power brakes after auto start-stop startup. Warning lamps/messages/other symptoms prior to failure: No symptoms prior to the failure. Upon startup caused by auto start-stop feature, the symptoms are as follows: All warning lamps illuminate and several messages display on the instrument cluster screen about loss of ESC, ABS, traction control, collision avoidance, adaptive cruise control, and others. One by one, the warning lights go out within 1 minute, except ABS. Power assist for the brakes is not available while this light is illuminated. Within approx. 2 minutes, the ABS light goes out and brakes function normally again.

About 30 minutes after driving at low/ moderate speeds, the emergency automatic braking system and five other braking systems failed while the vehicle was in motion. Parking brake was used but nothing worked until the car was in neutral and came to a natural stop. Almost caused an accident.

Bought my son 16 year old a new truck, truck only has 517 miles on it. He was driving 45 miles/hour on street, dashboard warning lights all lit up ABS, Brake and Check Engine. Brakes failed. Was able to pull into a parking lot eventually but a very serious safety issue/concern and this truck should be recalled immediately.

The forward collision avoidance system which controls the automatic emergency braking is showing as unavailable. This is after the parking brake warning light comes on and the brake master cylinder or BCM or both makes clicking noises after driving.
