General Motors is recalling 67,380 electric vehicles after discovering a software defect that could cause a temporary loss of braking at low speeds. The problem affects selected Cadillac and Chevrolet models and could increase the risk of a collision if drivers are unable to slow or stop their vehicles as expected.
The recall covers certain Cadillac LYRIQ, CELESTIQ and VISTIQ models, alongside Chevrolet Blazer EVs. Filed with the National Highway Traffic Safety Administration (NHTSA) on October 29, 2026, the campaign follows reports of incidents in which vehicles experienced unexpected braking problems despite having previously received software improvements.
What is the problem?
The defect involves software within the brake system control module (BSCM), which manages important braking functions. Under certain driving conditions, the software may incorrectly calculate wheel movement and temporarily release braking pressure.
The problem can occur when a driver lightly applies the brakes while making a sharp, low-speed turn, particularly when the vehicle travels over a bump or depression, such as an uneven driveway entrance. A momentary release and reapplication of the brakes can cause the software to misinterpret wheel movement, potentially resulting in a temporary loss of braking.
GM says normal braking function returns when the driver presses the brake pedal again. However, even a brief interruption in braking can create a dangerous situation, particularly when maneuvering around pedestrians, other vehicles, or obstacles.
The issue came to light following an April 2026 incident involving a 2024 Cadillac LYRIQ that struck a garage while moving at low speed. GM subsequently conducted testing and confirmed that a specific combination of vehicle configuration and driving conditions could trigger the problem. The manufacturer has since identified 24 potentially related complaints, including 20 minor accidents.
What owners should know
The recall affects the 2023-2027 Cadillac LYRIQ, 2025-2026 Cadillac CELESTIQ, 2026-2027 Cadillac VISTIQ, and 2024-2027 Chevrolet Blazer EV, although not every vehicle within these model ranges is necessarily affected.
For the LYRIQ and Blazer EV, the recall is limited to vehicles equipped with performance all-wheel drive (pAWD). On the Blazer EV, this configuration is available on the SS and Police Pursuit Vehicle (PPV) versions.
GM will correct the problem by updating the brake system control module software. The update can be delivered over the air to compatible vehicles or installed by an authorized dealership, free of charge.
