GM Recalls 67,380 EVs Over Brake Software Flaw

General Motors is recalling 67,380 electric vehicles in the United States because a software defect in the brake system control module can cause a temporary loss of braking at low speeds. GM filed the recall with the National Highway Traffic Safety Administration on October 29, 2026. It's campaign 26V717, and GM's own number is N262570900.

The covered vehicles are the 2023–2027 Cadillac Lyriq, the 2025–2026 Cadillac Celestiq, the 2026–2027 Cadillac Vistiq and the 2024–2027 Chevrolet Blazer EV. The Lyriq accounts for the bulk of the population. Not every example is in: the defect is tied to performance all-wheel-drive versions, option code X0E, so the VIN, not the badge, decides whether a given vehicle is covered.

The failure needs a specific sequence. A driver braking lightly at low speed through a sharp turn hits a bump or a dip, releases the brakes briefly and reapplies them. The module's slip calculation can misread the wheel movement in that moment and cut braking. GM's filing says normal braking returns on the next press of the pedal.

GM's report cites 24 potentially related complaints, including 20 minor accidents and two allegations of minor injuries, as of October 29. Those are allegations in a filing, not findings, but they're the reason a low-speed defect gets a full recall instead of a quiet software note. A car that rolls when its driver expects it to stop doesn't need highway speed to hurt someone.

For the Lyriq, this is familiar ground. GM recalled 21,469 all-wheel-drive 2023–2024 Lyriqs in August 2024, campaign 24V-589, over brake-control software, and NHTSA has since escalated its own examination of the Lyriq's brake module to an engineering analysis. Whether the new defect is the 2024 fault returning or a different bug in the same module is a question GM's filing doesn't settle.

The remedy is software. GM will update the brake system control module free of charge, delivered over the air where the vehicle supports it or at a dealership. The company says it has already corrected the software in production, with the fixes phased into the 2026 and 2027 model years between August and October 2026.

Owner notification letters are expected to go out December 14, 2026. The recalled VINs have been searchable on NHTSA's recall site since October 29, and owners can also call Cadillac at 1-800-333-4223 or Chevrolet at 1-800-222-1020 with GM's recall number, N262570900. Checking takes two minutes and beats waiting for the envelope.

The pattern matters beyond one campaign. Brakes used to fail as hardware: worn pads, leaking lines, cracked rotors. In an electric vehicle run by software, the brake pedal is a request the computer can misread, and the repair is a file. GM's owners will get their fix the same way they get a phone update, which is convenient, and also the whole problem.
