General Motors is recalling 67,380 electric vehicles across its Cadillac and Chevrolet lineups after identifying a software defect that could temporarily reduce braking power. The issue affects several 2023-2027 model-year vehicles and increases the risk of a crash.
The problem involves a defect in the brake system control module (BSCM), which could malfunction under specific driving conditions and cause a temporary loss of braking power. Drivers may be able to restore braking by pressing the brake pedal again.
Which GM Electric Vehicles Are Included in the Recall?
The safety recall covers four electric vehicle models from Cadillac and Chevrolet:
- 2023-2027 Cadillac Lyriq: 44,585 vehicles.
- 2024-2027 Chevrolet Blazer EV: 3,911 vehicles.
- 2025-2026 Cadillac Celestiq: 82 vehicles.
- 2026-2027 Cadillac Vistiq: 18,802 vehicles.
GM estimates that 100% of the recalled vehicles are affected by the defect, meaning the entire recall population is potentially exposed to the software problem.
How the Brake System Software Defect Occurs
The problem can develop when a vehicle is moving slowly, making a sharp turn, and traveling over a bump while the driver lightly applies the brakes. Under these conditions, the brake system software may malfunction, resulting in a temporary interruption of braking power.
Pressing the brake pedal again can restore the braking function. However, even a brief interruption could create a dangerous situation for drivers and other road users.
GM discovered the issue after a technical expert reported an incident involving a Cadillac Lyriq that struck a garage at low speed in April. Subsequent testing successfully reproduced the problem, even though the vehicle had already received software improvements introduced through an earlier recall.
GM Identifies 24 Potentially Related Complaints
During its investigation, GM identified 24 potentially related complaints involving the braking problem. These reports included 20 minor accidents and two allegations of minor injuries.
The automaker determined that the condition increases the risk of a crash, prompting the recall covering the affected Cadillac and Chevrolet electric vehicles.
How GM Plans to Fix the Braking Problem
GM will address the defect through a software update to the brake system control module. Owners of vehicles equipped to receive over-the-air updates can receive the correction remotely, provided their vehicles meet the necessary requirements.
Owners whose vehicles cannot receive the update remotely will need to visit a dealership to have the software installed manually.
The automaker plans to begin notifying affected owners on December 14, 2026, through a phased recall campaign. Vehicle identification numbers (VINs) have been searchable through the recall system since October 29, 2026.
GM has also implemented the software correction during production for specified 2026 and 2027 model-year vehicles, depending on the model.
The recall covers 67,380 Cadillac and Chevrolet electric vehicles affected by a braking software defect. The planned software updates are intended to correct the problem and address the temporary loss of braking power identified during the investigation.
