2024 Chevrolet Colorado Brakes Problems

About two weeks ago my truck popped up a message asking if I had installed new brake pads. When I selected no, on my Home Screen, where I can see the systems of my truck the front bake wear indicator no longer showed a percentage. When I inspected my brake pads the front outer pads still had a good amount of pad left, but when I checked the inner pads they had been severely worn down compared to the outers. On 4/1 I brought my truck to a Chevy dealership to have them diagnose why there is such uneven brake pad wear. After they inspected the brakes the dealership then told me that due to the brake pad clips being installed improperly my pads were wearing out unevenly. The dealership also showed me a service bulletin (25-NA-365) that GM had put out for trucks in the 2023-2026 models that stated due to a factory installation defect on the clip that holds the brake pads in place it is causing uneven wear on the brake pads. I told the dealership that the clip causing uneven wear on the brake pads could become a safety concern if owners don’t know about this because the braking effectiveness of the truck is wearing out faster than what the owner is told by the sensor. I told them in extreme cases that if the pad completely wears out then the rotor could be damaged and cause a very significant impact to the safety of the vehicle because the braking system will be severely degraded. I was told that since it is just a service bulletin the dealership and GM do not have to cover the repairs of the brake pads because a service bulletin is not the same as a recall and that brake pad wear is a normal maintenance item. My concern is that trucks with similar mileages as mine of 20000 miles are wearing their brake pads out at an alarming rate and the dealership and GM are not taking the responsibility to ensure that the issue is resolved and new pads are replaced to ensure proper braking effectiveness on the roads.

My truck only has 16,600 miles on it and the rotors and brakes are already shuddering. The dealership told me I needed my front and rear brakes and rotors replaced. It is beyond ridiculous when my last truck a 2020 Chevy Colorado had no rotor or brake problems and have 90,000 miles when I traded it in.

there have about 4 incidents where my vehicle has engaged the automatic emergency breaks while I’m driving, even though there are no cars around me close enough to cause that reaction. called 911 on most recent incident to get medical evaluation to check chest from seat belt sudden locking

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!

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.

The vehicle is registered to me; my mother was the driver at the time of the failure. At ~2,963 miles, the truck developed intermittent check engine and ABS warning lights. The dealer pulled DTC C058A (brake system control module) and P25A2. Per GM bulletin PIT6012A, the battery was replaced and a brake plunger motor sensor learn was performed. The same codes returned within weeks. The dealer then diagnosed internal failure of the brake master cylinder and reservoir, documented the vehicle as "unsafe to drive," and replaced both under warranty. The truck sat at the dealer over six weeks due to a nationwide parts backorder. Repairs were completed April 4, 2025. On May 2, 2025, at ~6,500 miles, the driver was traveling downhill on a city street in the rain at roughly 20 mph. The brake pedal suddenly became hard and resistant. Despite full-force pedal pressure, the vehicle could not be stopped. It entered an intersection, struck another vehicle, then struck a tree. Front and side airbags deployed; the vehicle was totaled. The driver sustained a concussion, broken finger, and severe back and knee injuries, was transported by ambulance, and required months of concussion treatment including vestibular therapy. The hard, resistant pedal is consistent with failure of the electronic brake boost assist (eBoost) system, leaving only unassisted hydraulic braking (roughly 4–5x normal pedal force). This matches other owner reports and the class action in Barron et al. v. GM LLC, which cites defective master cylinders with a missing internal cartridge seal on the same platform. The vehicle is no longer available for inspection. The driver was concussed with significant short-term memory loss at the scene; statements in the police report may not reflect the mechanical failure. Full police report available on request (exceeds 10 MB limit).

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.

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.

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.

The contact owns a 2024 Chevrolet Colorado. The contact stated while driving 10 MPH and approaching a stopped traffic, the contact stated that the sun temporarily blinded his vision of the roadway. The contact depressed the brake pedal, but the vehicle failed to respond and crashed into a stopped motorcycle, causing the motorcycle and the motorcyclist to fall to the ground. Additionally, the contact stated that the vehicle was designed with the Forward Collision Avoidance: Automatic Emergency Braking (AEB) system, which failed to engage as designed. The motorcycle rider was able to escape the scene, while the contact's vehicle continued to move forward and to drive over the rear end of the motorcycle. The motorcycle was damaged and could not be ridden. The motorcyclist sustained physical pain and received first aid from the ambulance; however, the motorcyclist declined medical assistance and was picked up by his girlfriend. The contact did not sustain any injuries. The air bags did not deploy. The check engine warning light illuminated after the crash. The contact stated that the front end and the undercarriage of the vehicle were damaged. The contact was able to drive the vehicle from the scene. A Police report was filed. The vehicle was taken to the dealer's Auto Body Shop, where an assessment of the vehicle damage was being performed. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and a case was opened. The failure mileage was approximately 4,700.

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

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.

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.

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.
