I took my vehicle in several times for issues regarding the brakes. I was told for months nothing was wrong. The brake percentage was rapidly declining on the display and they just kept saying it would fix itself in an update. Finally the service brake alert came on prompting me to take it to the dealership again for the brakes. I was told my front brakes were completely gone and needed new pads and rotors and my back brake lines were severed and pouring brake fluid everywhere. I was told I was lucky I brought it when I did because I could have gone to stop and just not been able to. It was concerning because there was no warning or indication there was anything wrong and I kept being told everything was fine

At purchase, I noticed that the brakes felt spongy and were screeching when the salesmen pulled up. The salesmen stated that new brakes always screech due to burned plastic. Weeks later, I scheduled a servicing appointment with Chevy Crews in North Charleston, due to brake screeching, the repairmen told me again that the brakes had condensation on them, so he dusted them off and the screeching would stop in 3 weeks. 3 weeks later I returned again, the salesmen told me that GMC made the vehicles with faulty brakes. My vehicle was seen over 4 times for screeching brakes, thousands of consumers have complained about the same issue, and GMC has failed to act.

Approximately four weeks ago on 02/03/2026, during rainy conditions, the brakes on the vehicle did not function properly, creating a serious safety concern. At the same time, a hose connected broke and there was a strong burning smell coming from the vehicle. I also noticed fluid leaking from the vehicle. I immediately took the vehicle to the dealership for repair, and the vehicle remained there for approximately five days for inspection, parts, and repair. Additionally, this is now my third time bringing the vehicle in for service. During previous visits, I asked the service department about the condition of my brakes because they were making a squeaking noise and I was concerned about their performance. I was told by the service department that the brakes were fine, that I still had plenty of brake life remaining, and that the squeaking noise was normal. However, as of March 4, 2026, my vehicle displayed a new warning message stating “Service Brake Pad Monitor – Front Brakes.” This is concerning because the vehicle currently has approximately 25,490 miles. Given the previous brake concerns I reported and the dealership’s response that the brakes were normal, the new warning message raises additional concerns about the safety and reliability of the braking system. Because this defect involves the braking system and creates a safety concern, I am requesting that General Motors review my case under the applicable Lemon Law and advise me on the next steps toward either a vehicle replacement or buyback if the issue cannot be fully resolved.

What component or system failed or malfunctioned, and is it available for inspection upon request? The front and rear brake system is malfunctioning. Both front and rear rotors have developed significant premature heat “hot spots,” causing loud, persistent squealing and excessive heat from the front wheels. It began with the front brakesm July 2025 and as of October 2025 the rear brakes had the same issues. This vehicle is available for inspection upon request. ----- How was your safety or the safety of others put at risk? This issue involves the primary braking system. The front and rear brakes become excessively hot and produce loud, constant squealing. I am concerned about potential brake drag, caliper malfunction, or premature rotor damage, which could reduce braking efficiency or lead to brake failure. Because this affects stopping performance, it presents a potential safety risk to myself, passengers, and others on the road. ---- Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. The Chevrolet dealership confirmed that both front and rear rotors have heat hot spots and advised replacement of the rotors and brake pads. Although I replaced the front break parts as suggested this did not repairthe issues. The vehicle is currently under review by a GM technician, but they have delayed a response sense January 14, 2026. ----- Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes. The vehicle was inspected by a Chevrolet dealership and reviewed by a GM technician. It has not been inspected by police or insurance representatives. --- There were no dashboard warning lights. The primary symptom was loud, persistent squealing from the front and rear brakes and noticeable premature heat spots on all the roters. The noise developed within approximately one year of ownership and at relatively low mileage for a new vehicle.

I experienced complete brake failure while coming up to an intersection during rush hour. To avoid crashing into the vehicles in front of me I went off the road onto the shoulder and coasted until I stopped. During this “brake failure” popped up on my dash. (I have a picture) I ended up turning the car off and then starting it back up. Everything appeared to be fine, however I was not fine. I called the dealership right away and brought in. They diagnosed it as needing brake master cylinder and it took about 30 days for the vehicle to get fixed. Now I’m experiencing transmission fluid leaking. The vehicle shudders when accelerating.

I am experiencing a recurring battery/charging system detection warning with my vehicle that has not been resolved despite multiple service visits. The warning continues to reappear after the vehicle is returned to me, indicating the issue has not been properly diagnosed or repaired. My vehicle has been in the shop approximately 5 times for this same issue. Each time, I am told the problem is resolved or that they cannot replicate the issue, yet the warning returns shortly afterward. To date, no permanent fix has been provided, and the underlying problem has not been remedied. I have made repeated attempts to work with GM and the dealership, but meaningful assistance or escalation has not occurred. This ongoing electrical issue raises concerns about the reliability and safety of the vehicle, as well as GM’s failure to correct a known, documented problem. I am requesting appropriate escalation and resolution, including further diagnostic intervention by a regional service manager or field engineer, or consideration of alternative remedies if the issue cannot be permanently repaired.

Recurring failures related to brake system. When reversing, the rear brake assist system slams on the brakes for no reason even though no obstacles are present. This startles everyone in the vehicle and nearby traffic. On other occasions, the vehicle shows an error on the instrument cluster stating "Rear Brake Assist Unavailable". More recently, a persistent error began appearing on the instrument cluster stating "Service Brake Monitor", indicating a failure of the brake pad sensor. On top of all of this, the brakes are noisy and squeaky to the point where it wakes up my neighbors.

1EA26006 · Electronic Brake Module Component Failure
Opened Aug 21, 2026 · No close date supplied
Status: open (inferred from source dates) · Service Brakes
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.
