GM Recalls Over 67,000 Cadillac and Chevy EVs for Brake Software Glitch





Ensuring Safety: GM Addresses Critical Brake Software Flaw in Electric Vehicles
The Unforeseen Braking Anomaly
General Motors has initiated a recall for more than 67,000 Cadillac and Chevrolet electric vehicles due to a software flaw that could lead to intermittent loss of braking capability. This issue came to light following an incident involving a 2024 Cadillac Lyriq, which experienced a low-speed collision with a garage.
Identifying the Root Cause
Following the reported incident and an internal investigation, GM successfully replicated the braking anomaly. The core of the problem lies within the brake system control module's (BSCM) software. Under specific conditions, such as light brake application during a sharp turn over uneven terrain, the system's slip calculation can inaccurately interpret wheel movements, potentially resulting in a temporary loss of braking. This defect primarily impacts all-wheel-drive (pAWD) models.
Affected Vehicle Models and Scope
The recall encompasses a range of GM's electric vehicles, specifically targeting 67,380 units. The affected models include certain versions of the 2023–2027 Cadillac Lyriq, 2025–2026 Cadillac Celestiq, 2026–2027 Cadillac Vistiq, and 2024–2027 Chevy Blazer EV.
Incidents and Resolutions
GM's records show 24 field complaints related to this issue, with 20 involving minor collisions and two reporting minor injuries. These reports were filed between February 2024 and June 2026. In response, GM has already started implementing software revisions in its production vehicles to prevent future occurrences.
Remedy and Owner Notification
To rectify the issue, GM will provide a software update for the BSCM. This update will be available either through an over-the-air (OTA) download or via authorized dealerships, at no cost to the vehicle owners. Notifications to affected owners are scheduled to be dispatched in mid-December 2026. For additional assistance, owners can contact Cadillac or Chevrolet customer service, or refer to the National Highway Traffic Safety Administration (NHTSA) website, citing campaign number 26V717.
