Cadillac and Chevrolet EVs Recalled Over Brake Control Software
General Motors is recalling 67,380 electric Cadillac and Chevrolet models in the United States because faulty software in the brake system control module can cause a loss of braking in certain driving conditions. The campaign, numbered 26V-717, reached the US safety regulator NHTSA on 29 October, and recall tracker Automotor News published the details on 4 November.
Key takeaways
- 67,380 vehicles: Cadillac Lyriq, Vistiq and Celestiq, plus the Chevrolet Blazer EV.
- Model years range from 2023 to 2027, depending on the model.
- The fix is a free software update, delivered over the air or at a dealer.
- Owner letters are due to be mailed on 14 December 2026.
Which cars are affected
The recall spans four GM electric models from two brands. It covers the 2023-2027 Cadillac Lyriq, the hand-built 2025-2026 Cadillac Celestiq, the three-row 2026-2027 Cadillac Vistiq and the 2024-2027 Chevrolet Blazer EV. GM's internal reference is N262570900. The filing gives one total for the whole campaign and does not split the 67,380 vehicles by model. Owners can already check their VIN on the NHTSA website, where the affected cars became searchable on 29 October.
What goes wrong with the brakes
The fault sits in software, with no reported hardware failure. GM told NHTSA that a defect in the brake system control module (BSCM) software "may cause loss of braking during certain driving conditions". The component involved is the unit that runs the antilock brakes, traction control and electronic limited-slip control for the hydraulic service brakes. A sudden drop in braking performance raises the risk of a crash, which is why the problem was classed as a safety defect. The filing summary does not describe the exact conditions that trigger the fault, and it lists no do-not-drive advice.
How GM will fix it
The remedy is a new version of the BSCM software, free of charge. Most cars can receive it over the air, so owners may not need a workshop visit at all. Cars that cannot take the remote update will get it at a Cadillac or Chevrolet dealer. Official owner letters are scheduled for 14 December 2026. Cadillac customer service is on 1-800-333-4223 and Chevrolet on 1-800-222-1020.
What it means for owners
US owners of these four models should check their VIN on NHTSA's site, accept any pending software update as soon as it appears, and treat any brake warning light or change in pedal feel as a reason to stop and call the dealer. The NHTSA filing covers US-market vehicles only. The Lyriq is also sold in several European countries, so owners there should ask their local Cadillac partner whether the same software is installed in their car.
