See attached document for complaint. I am writing to formally notify you, pursuant to the California Song-Beverly Consumer Warranty Act (California Civil Code§§ 1790 et seq.), that my 2024 Chevrolet Blazer EV, VIN 3GNKDHRK4RSXXXXXX is subject to an active safety recall N252503010 for the parking brake system. GM has acknowledged the defect, but no genuine repair or remedy Is available. I have already experienced problems with the parking brake, which substantially impair the safety, use and value of the vehicle. Due to the severity of this defect, I have placed the vehicle at the dealership, Woodland Motors, and it will remain there until GM completes the buyback process. I refuse to drive it because it is unsafe. I further understand that GM has instructed the dealership to adjust the depth sensor as so-called remedy. This adjustment has no bearing on the parking brake defect and cannot be reasonably be considered a repair nor the taping of brake lines that they also instructed to do. It does not address the safety risk or brake failure or unintended activation. Under California Civil Code§ 1793.2, the manufacturer must repair any defect that substantially impairs the use, value, or safety of the vehicle within a reasonable number of attempts and within a reasonable period of time. Since GM has no remedy and cannot provide a repair, it is impossible to comply with this requirement. Accordingly, I hereby demand that GM immediately: Repurchase my vehicle for the full purchase price, including sales tax, registration, finance charges, and any incidental or consequential damages. In addition, I request GM immediately provide me with a loaner vehicle or GM-paid rental until this matter is resolved, as it is unsafe to operate my current vehicle. If GM fails to resolve this matter promptly, I will retain legal counsel and pursue all available remedies, including attorney's fees, court costs and civil penalties under California Civil Code §1794.

The vehicle was taken back to a dealer for the recall repair. The contact stated that the repair involved the installation of an anti-abrasive tape around the wiring harness. The manufacturer was notified of the failure, and a representative was sent to inspect the vehicle. The Chevrolet Representative was later informed by the dealer that the brake lines were already taped prior to the recall and that no additional repairs were needed. The vehicle remained in the possession of the dealer because the contact was concerned about the safe operation of the vehicle. The failure mileage was unknown.

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.
