At startup today vehicle displayed “Brake Assist Failure. Press Hard to brake. Speed limited.” It also displayed “service.” It also displayed “ESC,” and the word “service. An internet search indicated this may be a common problem of this vehicle, caused either by a software error in the Electronic Brake Control Module, or due to a defective brake master cylinder. There is a GM service notice for these defects, N242471431. Regardless of the cause, the brake is extremely mushy, and requires a high degree of force to stop the vehicle. GM says there is no recall due to this defect. This is a brand new vehicle and therefore it must be a defect in the vehicle. Given that braking is a fundamental safety issue, it’s hard to believe there is no recall already issued.

The driver and infotainment center is so dim during the day that it is dangerous to drive the vehicle. I have taken the vehicle in to the dealer 3 times and each time the dealer indicates that there doesn't appear to be a problem, but at no time to my knowledge have they taken the vehicle out into the sunlight, There have been 2 Software updates at the dealer and one OTA update so far with no improvement. The screens are so dim that there is no way you can tell what icons are there. If you try to do anything while driving, you are taking way too much time trying to look at the screens and as a result a serious and unnecessary amount of distracted driving is occurring. There is no way you could wear sun glasses and view the screen because it appears black. Don't open the panoramic sunroof or the problem is worse. Anti glare screen protectors make the situation worse. I have attached a document I provided to the dealer service department on my latest visit.

EA26006 · 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.
